Objective
A comparative study of manual and automated post processing software tools to measure CT parameters before Transcatheter Aortic Valve Implantation (TAVI).Patients and methods
51 patients were included; all admitted to the Cardiology Department with clinically established severe aortic stenosis, in whom TAVI was the treatment of choice. All patients underwent CT angiography (CTA) pre-TAVI. The CT images were post processed and the needed CT parameters were calculated using both manual and automated methods. The results were compared for statistical analysis.Results
Only 43 patients completed the study, with mean age 65?years old. The automated software provided accurate almost similar results as the manual method, especially for aortic annulus area and aortic circumference measurements (p-value?=?1 and 0.548) and was accepted for left and right coronary artery ostium height (p-value?=?0.191 and 0.635).However, there was a statistically significant difference for the minor diameter axis and mean annular diameter (p-value?=?0.001 and 0.021).Conclusion
The automated software introduced rapid, accurate and reliable measurements for the aortic annulus in cases prepared for TAVI and can be used as a standard method. Also, it can be performed by junior staff with avoidable human errors. 相似文献2.

Objective
The aim of our study was to determine the role of PET-CT in detection of recurrence and metastasis of renal cell carcinoma.Patients and methods
Our study included twenty patients with renal cell carcinoma. All patients were from those attending to radio-diagnosis department in Sharq El Madina Hospital in Alexandria referred for PET/CT study. The following were done for all patients: Careful history taking, clinical examination, ultrasound, enhanced CT and PET/CT.Results
One patient (5%) had positive PET/CT findings at different bone sites with high metabolic activity however these lesions were negative at CECT without any anatomical changes neither lytic nor sclerotic changes could be detected at these bone sites, with sensitivity, specificity and accuracy of PET/CT were 100%, 83% and 95% respectively.Conclusion
PET/CT had advantage to PET and CT alone, making it an appropriate imaging technique in recurrence detection, therapeutic assessment and follow up of patients with renal cell carcinoma. 相似文献3.

Aim of the study
The aim of this study was to explore the role of the DWI in assessment of peri-anal fistula and whether it can replace post contrast study.Patients and methods
MRI examinations was done for 35 patients. Images were reviewed for the presence and number of visible fistulas, internal openings, secondary extension, horse shoe and abscess. Apparent diffusion coefficient (ADC) measurement of suspected fistula tracks and abscess cavities was done to assess activity. Comparison between TIRM, DWI and post-contrast T1-weighted fat saturated sequences was done. Surgical findings were the reference standard.Results
Contrast enhanced images were superior to DWI in detection of primary fistula and internal opening while they were equivalent in detection of secondary extensions and abscess. There was no significant difference in overall accuracy of detection of perianal fistula and its complications between combined (DWI and TIRM images) and post contrast images. There was significant difference between ADC values of active and inactive fistulae and between abscess and inflammatory reaction.Conclusion
Combined DWI and TIRM is equivalent to post contrast images in detection of primary and complicated fistula. DWI is useful in differentiation between abscess and inflammatory reaction, and assessment of disease activity. 相似文献4.

Background
Urinary tract injuries occur in 3–10% of abdominal trauma. Early recognition and diagnosis of ruptured bladder is essential to lower this mortality rate. CT is the method of choice for the evaluation of patients with blunt or penetrating abdominal and/or pelvic trauma. Imaging in patients with suspected bladder injury with CT cystography may be performed using either an intravenous or retrograde technique.Aim of work
The aim was to evaluate the role of CT in diagnosing traumatic urinary bladder injuries.Materials and methods
The study was carried out on 32 patients with suspected traumatic urinary bladder injury. All patients were subjected to contrast-enhanced CT study and classified according to Sandler et al. classification of urinary bladder injuries.Results
All patients were classified according to the type of the encountered urinary bladder trauma. Type I injury was diagnosed in 3.1% of patients, type II in 18.8%, type III in 3.1%, type IVa in 12.5%, type IVb in 43.7% and type V in 18.8%. 21.8% of patients were managed conservatively, while 78.2% of patients underwent surgical repair.Conclusion

The wrist joint is a complex joint containing several intrinsic and extrinsic ligaments that contribute to carpal stability. There is increased incidence of ligamentous/capsular injury following trauma.
Objective
The aim of this study was to assess the value of high resolution MDCT arthrography in detection of various ligamentous and capsular injuries of the wrist in post-traumatic writ pain.Patients and methods
From August 2016 to February 2017 Seventeen patients with posttraumatic wrist pain underwent MDCT arthrography primarily through radiocarpal injection and using high resolution study, all patients have negative MRI study of the wrist.Results
59% of cases had ligamentous/capsular tear. The most frequent was the capsular tears. Incomplete intrinsic ligament tears were observed, the dorsal scaphotrapezio-trapezoid ligament was the commonest to be affected. Class IA traumatic TFC tear was found in 12%. There was significant high positive correlation between the VAS score for wrist pain and the presence of ligamentous/capsular tear in absence of bone fracture.Conclusion
MDCT arthrography of the wrist is an excellent imaging method that can detect MRI occult ligamentous tear in unexplained post traumatic pain. 相似文献6.

Objective
Aim of this study was to assess role of Multidetector computed tomography (MDCT) Renal Angiography in determining the anatomical eligibility for renal sympathetic denervation in resistant hypertensive patients.Subjects and methods
This study included 30 patients, referred from hypertension unit in Zagazig University Hospital, with refractory systemic hypertension [an office blood pressure (BP) >140/90?mmHg despite treatment with at least three drugs, including a diuretic in adequate doses]. All cases were performed using a 128-slice MDCT scanner. All data were transferred to an imaging workstation for reconstruction and analysis. Axial source images were post-processed to produce multiplanar reformation, curved planar reformation, maximum intensity projection and volume rendering images.Results
Most patients (46.7%) had an A1/A1 type renal artery (RA). 66.7% were completely eligible (CE), 23.3% were partially eligible (PE), and 10% were non eligible (NE). Regarding intraobserver agreement; concordance between two readings by the same radiologist was in 96.7%, while discordance was in 3.3%. Regarding interobserver agreement; concordance between two radiologists was in 93.3% while discordance was in 6.7%.Conclusion
MDCT renal angiography gives valuable knowledge to the interventional radiologist and cardiologist before renal artery denervation (RDN) to increase the success rate. 相似文献8.

Aim of work
To assess the role of color Doppler ultrasonography and multidetector computed tomography angiography (MDCTA) in diagnosis of uterine arteriovenous malformations (AVMs).Methodology
Twenty patients were referred to the radiodiagnosis and imaging department, faculty of medicine, Tanta University from obstetric and gynecology department. All patients were suspected clinically to have uterine arteriovenous malformations. All were subjected to history taking regarding clinical state, laboratory investigation and color Doppler ultrasonography and multidetector computed tomography angiography of the pelvis.Results
Color Doppler ultrasound sensitivity was 100% in detecting a uterine hypervascular lesion and highly suggesting the diagnosis of uterine AVM and the sensitivity of MDCT angiography was 100% in diagnosing and evaluating uterine AVM.Conclusion
Doppler US can strongly suggest the presence of AVM but patient should undergo CT angiography for definitive diagnosis and possible embolization, as CTA helps in providing valuable cross sectional anatomical details about the lesion, its extent and its surroundings. 相似文献10.

Objectives
To assess the role of 320 MDCT angiography in the evaluation of extra cardiac, vascular anomalies of great arteries and compare its results with transthoracic echocardiography and its impact on treatment planning.Materials and methods
This study included 39 patients, their age ranged from 16?days to 13?years. All of these patients underwent echocardiography and CTA examination using 320-MDCT. The images were analyzed using reconstruction techniques including MPR, cMPR, MinIP and VR techniques, the results were compared with surgical/catheter angiographic data.Results
MDCT was superior to echocardiography in diagnosis of great arteries anomalies (aortic and pulmonary). We found excellent agreement between 320-MDCT and surgery/catheter angiography with k?=?1.000 sensitivity, specificity, PPV, NPV, accuracy for aortic anomalies were 100%, 100%, 100%, 100%, 100% and 82.05%, 100%, 100%, 56.25% and 85.42% for MDCT and echocardiography respectively, and that of pulmonary anomalies were 100%, 100%, 100%, 100%, 100% and 84.62%, 100%, 100%, 92.86% and 94.87% for MDCT and echocardiography respectively.Conclusion
The main advantage added by 320-MDCT to transthoracic echocardiograpy was excellent delineation of the great arteries anomalies with suitable operative/catheteric decision without the need for the invasive diagnostic catheter angiography to the patients. 相似文献11.

Objective
The prognosis of different histologic subtypes of RCC varies and affects management. Patients with chromophobe or papillary RCC have better prognosis than those with clear cell RCC. The aim of our work was to study the utility of DCE and DWI in the preoperative prediction of renal cell carcinoma subtypes, using histopathology as a gold standard method of diagnosis.Patients and methods
Thirty five patients with 38 renal masses were included in the study. All had DCE MRI studies with DWI sequences, CER and ADC values calculation for normal and diseased renal tissues.Results
The Mean ADC value of normal renal parenchyma was significantly higher than RCC. The CER and ADC values for Clear cell RCC were higher than Papillary and Chromophobe RCC. No statistically significant difference was found between the CER & ADC values for Papillary and Chromophobe RCC. CER & ADC values of clear RCC were higher than non clear RCC.Conclusions
DCE MRI in addition to DWI & ADC appears as a very helpful imaging tool in the differentiation between clear cell and non-clear cell RCCs. 相似文献12.

Aim of the work
To evaluate the role of fast imaging employing steady-state acquisition (FIESTA) together with conventional MRI and MR myelography (MRM) sequences in evaluation of brachial plexus traumatic roots injury in adults in correlation with surgical outcome.Subjects and methods
This prospective study included 20 patients (their mean age was 22.6?years). All patients came with initial clinical diagnosis of traumatic brachial plexus and positive electrodiagnostic tests. All underwent conventional MRI, FIESTA and MRM and the imaging findings were correlated with surgical outcome.Results
Combined evaluation of the conventional MRI, FIESTA and MRM sequences yielded highest diagnostic sensitivity (95%) of pseudomeningocele and non-visualized nerve root detection which are the most important marks of brachial plexus root injury compared to conventional MRI combined with FIESTA (90%) and to conventional MRI combined with myelography (85%)Conclusion
In traumatic brachial plexus root injury, it is vital to differentiate between pre- and postganglionic injuries. Combined conventional MRI/FIESTA/MRM depicted root injury has the highest sensitivity in detection of psuesdomeningiocele and non-visualized nerve root. 相似文献13.

Aim of the work
The aim of this study was to assess the rule of delayed T1 post contrast sequence in detection of active lesions in multiple sclerosis patients by comparing the early and delayed T1 post contrast images.Materials
This was a prospective study and included 30 known multiple sclerosis patients with clinically suspected activity referred form neurology department to radiology department for MRI examination.Methods
All patients were subjected to the followings: –?Conventional routine MRI of the brain using 1.5?T machine. –?T1 delayed post contrast sequence (about 10?min after contrast injection).Results
The included MS cases showed 162 lesions of variable distribution as 113 lesions were supratentorial while 49 lesions were infratentorial. Among 162 lesions in the current cases 58 lesions showed post contrast enhancement while the remaining 104 lesions were non enhancing. From the total of enhancing lesions (58), 16 lesions showed early enhancement while 42 lesions showed delayed enhancement.Conclusion
Delayed T1 post contrast is an important sequence for detection of active MS plaques as it increases the sensitivity of MRI. 相似文献14.

Objective
The aim of this work is to highlight the diagnostic value of multidetector CT in assessment of gastric malignancy compared to surgical and pathological results.Method
A Multicenter study was conducted from (October 2011–March 2014). Thirty-five patients were included, eight females and twenty-seven males with mean age 50?years (34–81). All patients were subjected to; Full history taking and physical examination, Multidetector Computed Tomography (MDCT), and Upper Gastro intestinal endoscopy. Triphasic CT was used using oral and IV contrast where scanning at arterial phase cuts were taken after 15?s followed by portovenous 20–25?s after the arterial phase.Results
74% of Lesions detected at the study were mural thickening, with adenocarcinoma pathology. MDCT T staging compared to pathological staging was highly significant. Only 33 cases had pathological reports suitable for comparison with the MDCT staging. True positive cases were 30, false positive cases were 2 cases and false negative was only one case, Thus giving sensitivity 96.7% and accuracy 91%.Conclusion
Multidetector CT can play an important role in diagnosis and preoperative staging of gastric cancer. 相似文献15.

Objective
The objective of this study was to outline the role of multidetector computed tomography angiography (MDCTA) in the evaluation of patients with thoracic traumatic aortic injuries (TTAIs) pre- and post-thoracic endovascular aortic repair (TEVAR)Subjects and methods
Forty-two patients (30 men and 12 women; age range, 24–67?years; mean age, 42.4?±?11.5?years) with blunt chest trauma who underwent TEVAR for TTAIs were retrospectively reviewed in this study during the 66-month review period. All patients were subjected to MDCTA followed by conventional aortography as part of planning for TEVAR. Postoperative MDCTA follow-up was done for all patients within one month of TEVAR. MDCTA findings before and after TEVAR were reported.Results
The most common TTAI site was the aortic isthmus (85.7%). The MDCTA findings in 42 patients included pseudoaneurysm (38), intimal tears (30), transection (16), intraluminal haematoma (2), dissection (2), periaortic haematoma (42), and minor aortic contour abnormality without pseudoaneurysm (2). The most common associated injury was haemothorax in all patients. Postoperative MDCTA follow-up revealed only two patients with type I endoleaks.Conclusion
This study confirmed that MDCTA plays an essential role in the assessment of patients with TTAIs before and after TEVAR. 相似文献16.

Objective
To assess the diagnostic accuracy of diffusion weighted imaging (DWI-MRI) being a non-contrast based MR sequence versus dynamic contrast enhanced MRI (DCE-MRI) in the preoperative loco-regional staging of the cervical carcinoma.Methodology
Fifty cases of proved cancer cervix prior staging subjected to dynamic post contrast technique: one pre-and six post contrast phases (40?s each). DWI was scanned using different b values and ADC values were measured.Results
DWI was the most accurate in staging operable cases (93.3%).Parametrial infiltration was overestimated in 3 cases versus 4 cases in DCE-MR. DWI showed 100% sensitivity, positive predictive value and accuracy in the assessment of locally advanced carcinomas. In metastatic lymph nodes, DCE-MR showed the least accuracy of 86%.Conclusion
DWI is helpful in discriminating local from locally advanced cervical carcinomas. DCE-MR can delineate cervical carcinomas confined to the uterus and exclude bladder/rectal invasion. 相似文献19.
