Background
Ninety percent of hepatic cancers are hepatocellular carcinomas (HCC) which have an unfavorable prognosis. HCC is a hypervascular tumor supplied mainly by the hepatic artery. It has a higher blood supply than the surrounding hepatic tissue due to neovascularization. Computed tomography with perfusion imaging (CTP) is a non invasive tool which quantifies the blood flow parameters of HCC and compares it to the surrounding tissue.Purpose
To prove that CTP is a valuable diagnostic tool in diagnosis of HCC and posttherapeutic assessment.Patients and methods
One hundred and twenty-six HCC patients with 150 focal lesions are enrolled this study. Perfusion parameters are quantified and results are compared to those of triphasic CT.Results
CTP detected 141 lesions with 94% sensitivity and 40% specificity with elevated arterial perfusion (AP) and perfusion index (PI) with low portal flow (PF). It missed 5 lesions because of their hypovascularity and 4 lesions following radiofrequency ablation (RFA) and trans arterial chemo embolization (TACE).Conclusion
CTP is a safe and specific imaging tool for diagnosis and assessment of therapeutic interventional procedures in HCC. 相似文献2.

Purpose
To highlight the relationship between coraco-humeral distance and subscapularis tendon tear.Material and methods
Sixty-two shoulder MRI studies were examined. Twenty-two patients had partial or complete tear of subscapularis tendon and forty shoulder as a control group. Axial and oblique sagittal MR images were examined to measure the coraco-humeral distance followed by statistical analysis to correlate the distance with tendon tear.Results
A cut-off value of 8.25?mm for the coraco-humeral distance gave a sensitivity of 77.5% and specificity of 72.7% for subscapularis tendon tear.Conclusion
There is a well-known relationship between the coraco-humeral distance and the subscapularis tendon tear and its meticulous assessment in subjects with pain in the anterior shoulder region increases the diagnosis of subcoracoid impingement. 相似文献7.

Background
Assessment of treatment response in patients with a brain tumor is paramount, as true tumor recurrence and radiation necrosis are similar looking on conventional MRI.Purpose
To evaluate the role of dynamic susceptibility contrast (DSC) perfusion magnetic resonance imaging in the differentiation between recurrent brain tumors and radiation necrosis.Material and Methods
Twenty patients with a history of operated primary brain tumors and postoperative radiotherapy with or without chemotherapy were enrolled in this prospective study having conventional MRI findings of enhancing lesion suspicious of being recurrence or radiation necrosis. All patients were examined by DSC-perfusion MRI. Definitive diagnosis was reached through either subsequent surgical biopsy or follow up over 6-12 months.Results
Fifteen patients (75%) were diagnosed as tumor recurrence and 5 patients as radiation necrosis (25%). The relative cerebral blood volume (rCBV) and relative peak height (rPH) were significantly higher (P?<?0.05) in recurrent tumors than in radiation necrosis lesions. The rCBV and rPH thresholds in differentiating between them were 1.8 and 1.22 respectively with 87%, 93% sensitivity and 100% specificity for each respectively.Conclusions
DSC-perfusion MRI is a valuable non-invasive tool besides conventional MRI whenever available to differentiate between radiation injury changes and tumor recurrence. 相似文献13.

The aim of this prospective study was to evaluate the diagnostic performance of the use of strain index ratio by sonoelastography to differentiate between benign and malignant breast lesions.
Patients & Methods
This prospective study including 40 females, complaining of breast masses which were suspicious to be malignant on clinical examination. All patients were submitted to B-mode Ultrasound and sonoelastography. Biopsy as a gold standard and pathological study were done for all breast lesions.Results
US examination of every mass was done and categorized according to BI-RADS categories according to ACR2013, according to US lexicon. Sonoelastography examination with Lesions classification was performed on the basis of a 5-point scoring method proposed by Tsukuba elasticity score. Then measurements of strain ratio were done. Statistical analysis of combination of the three methods was sensitivity of 96.7%, specificity of 100% when we use cut off value of 3–4 in elastography score and ≤3 cut off value of strain ratio.Conclusion
The combined use of strain ratio with Tsukuba score and BI-RADS categorization increased the diagnostic performance in differentiation between benign and malignant breast lesions. 相似文献15.

Objectives
To evaluate accuracy of computed tomography angiography (CTA) in evaluation of post traumatic renal vascular injury.Patients and methods
38 patients were presented with post traumatic intermittent or persistent hematuria. Renal CTA and digital subtraction angiography (DSA) were done for all patients.Results
CTA demonstrated pseudoaneurysm (PA) in 30 patients (78.9%) and no vascular lesions in 8 patient (21.1%). CTA had 86.11% sensitivity and 50% specificity in detection of post traumatic renal pseudoaneurysms, CTA missed diagnosis of renal arteriovenous fistula (RAVF) in 10 patients which discovered later by DSA.Conclusion
CTA with MIP as non invasive technique widely replaced renal DSA in detection of posttraumatic renal pseudoaneurysm. Renal DSA is still best modality in detection of RAVF and also has the upper hand in planning of selective renal artery embolization for the management of persistent or delayed hemorrhage from renal vessels. 相似文献16.

Introduction
To determine whether Computed Tomography Perfusion (CTP) can predict treatment response and prognosis in non-small cell lung cancers (NSCLC). To determine which one of the perfusion parameter correlated best with treatment outcome.Methods
Sixteen patients with NSCLC underwent CTP before and after completion of chemo-radiotherapy. Patients with complete and partial response were grouped as responders and patients with stable and progressive disease were grouped as non-responders. Pre and post-treatment whole tumour perfusion parameters (blood flow - BF, blood volume - BV, mean transit time - MTT and permeability surface area product - PS) were compared between responders and non-responders.Results
Responders had higher baseline BF and PS values than non-responders; P?=?0.047, 0.028 respectively. On 1?year follow up, patients with even 2.65% increase in PS value from baseline developed metastasis while patients with decrease in PS value by 24% did not develop metastasis (P?=?0.05). Greater decrease in BF values (17%) were noted among responders than non-responders (2.4%) following chemoradiation, though the results were not statistically significant (P?>?0.05).Conclusions
Tumours with higher baseline BF and PS respond well to chemo-radiation. Changes in the PS values can predict the development of metastasis and hence, the long term outcome. 相似文献17.

Purpose
The aim is to assess the usefulness of cine phase-contrast MRI for evaluation of patency of endoscopic third ventriculostomy operation and correlation with clinical state postoperatively.Material & methods
Prospective study performed upon 20 patients who underwent ETV operation, concerned on obstructive hydrocephalus (age range, 4–63 years; 11 male & 9 Female). Cine PC-MRI CSF flowmetry technique was applied for qualitative and quantitative assessment of CSF flow dynamics through ETV stoma to assess its patency.Results
The patency of ETV stoma was evaluated according to overall flow amplitude (OFA) as it was the most effective variable to predict the response to surgery, we found that when OFA value is ≥75?μL, the sensitivity and specificity of our technique to determine patient improvement were 71.4% and 76.9%, respectively.According to OFA, we classified the state of ETV stoma into three subcategories: patent stoma with adequate flow; OFA value ≥75?μL (10 patients), patent stoma with low flow; OFA value from 25 up to <75?μL (4 patients) and obstructed stoma with impaired flow; OFA value <25?μL (6 patients).Conclusion
Cine phase-contrast MR imaging is an effective and reliable method for evaluation and follow up of the ETV patients postoperatively. 相似文献18.

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.
