Purpose
Evaluate MDCT findings in patients with blunt chest trauma with a demographic evaluation of number and percentage of each pattern over 6?months at University Hospital.Patients and methods
This study involved 125 patients, including 90 males and 35 females with a mean age of 51.4?years. They were exposed to blunt chest trauma and were referred to the emergency radiology department. All patients were subjected to clinical examinations with medical history interview, plain chest X-ray, and MDCT of the chest with 3D reconstruction.Results
Road traffic accidents were the most common mechanism of trauma, accounting for 56.8% of the 125 cases. Chest pain was the most common clinical presentation, observed in 76%. Both sides of the body were affected in 41.6%; the right side was affected in 29.6%; and the left side was affected in 28.8%. Radiological findings among the patients in the order of frequency were pleural injuries in 72% of the patients, parenchymal lung injuries in 56.8%, chest wall injuries in 40.8%, mediastinal injuries in 11.2%, diaphragmatic injuries in 4.8% and tracheo-bronchial injuries in 1.6% of the patients.Conclusion
Chest trauma may cause significant morbidity, and MDCT could lead to critical changes in a patient's management. 相似文献2.

Aim
To compare the role of chest US and bedside plain chest radiography in the evaluation of intensive care patients having pleural effusion and pneumothorax. Chest computed tomography has been used as an ideal standard.Patients and methods
Sixty critically ill patients with chest troubles and positive CT, were be studied with chest US and bedside CXR .Two pathologic abnormalities were be evaluated: pneumothorax and pleural effusion. Each hemithorax had been examined for the existence or absence of each pathology. All patients had been assessed by clinical examination of chest, full clinical history, laboratory assessment. All patients who had pleural effusion underwent US guided FNAC.Results
One hundred twenty hemithoraces had been investigated by the three imaging techniques. The sensitivity, specificity and diagnostic accuracy of bedside CXR were 54.5, 96 and 83.3% for pneumothorax and 76.2, 70.6 and 75% for pleural effusion, respectively. The corresponding values for chest US were 85.7, 97.9 and 95.2% for pneumothorax and 100, 100, and 100% for pleural effusion, respectively.Conclusions
In evaluation of ICU patients with pleural effusion and pneumothorax, chest US is the first bedside tool with high diagnostic performance. These chest conditions are urgent especially in seriously ill patients, as both need US guided drainage. Chest US has many advantages, including non invasive examination in multiple planes, free of radiation hazard, less expensive, real-time, high sensitivity and diagnostic accuracy in chest lesions detection. Lung ultrasound is being exclusive than bedside chest X-ray and equal to chest CT in diagnosing pleural effusion and pneumothorax. 相似文献3.

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8.

Back ground
In some patients suffering from chest pain, we must start by non-invasive coronary CT angiography (CCTA) to protect these patients from unnecessary invasive coronary catheter angiography (CCA).Objective
Value of CCTA as the first diagnostic imaging modality in patient suffering from chest pain.Patients and methods
A total number of 100 patients were included in this study with mean age of 53.51?±?11.6 years. Our patients were divided into two groups, group (A) included 60 patients underwent both CCTA and CCA and group (B) included 40 patients underwent CCTA only. Then Framingham Risk Score was applied for 68 cases (68%) after exclusion of cases with previous coronary artery intervention as CABG or stent (32 cases).Results
We were calculated a cutoff point of Framingham Risk Score at which p value <0.001, sensitivity 85.7%, specificity 51.5%, PPV 65.2%, NPV 77.3% and accuracy 69.1%, it was 7.5%. The diagnostic statistics of MDCT for CABG with sensitivity (100%) and specificity (100%).Conclusion
It is reasonable to start with CCTA in patients with Ferminghaim Risk Score less than 7.5%, filtering the patients to avoid unnecessary CCA. CCTA should be the first imaging modality in patients with CABG suffering from chest pain. 相似文献9.

Background
Bismuth shield has been recently introduced for radiation protection of patient radiosensitive organs such as breast during chest CT with image diagnosis capability. The purpose of this study was to evaluate the dose reduction and image quality conserve using new bismuth-silicon composite shields during chest CT.Materials and methods
Scans were performed on a PMMA phantom using a 6-slice MDCT system. Dose reduction was calculated by placing ion-chamber in the 12?o’clock position for breast dose measuring. Chest CT scans was performed with and without new bismuth composite shields 10% by 0.5?mm and 1?mm thicknesses. Image quality was assessed by CT numbers and noise evaluation.Results
The results of using bismuth composite shields induced to dose reduction to 7% and 12% for 0.5?mm and 1?mm thicknesses, respectively. As a result of the using 0.5?mm and 1?mm bismuth composite shields, the mean CT numbers and noise increased by a factor of 0.01 and 0.02 and also from 0.08 to 0.13, respectively. Significant dose decline was measured and no relevant noise was found.Conclusion
Results showed that new bismuth-silicon composite shields have good potential to breast dose reduction with smallest noise for diagnosis in chest CT. 相似文献13.

Background
The ankle is frequently injured in trauma, overuse syndrome and inflammatory processes. Different imaging modalities assess the ankle, including plain radiography, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasonography (US).Purpose
Our objective is to assess the role of high resolution US as a valuable tool in the depiction of causes of ankle joint pain.Patients and methods
The study included 28 patients presented with ankle pain ranging in age from 17 to 60 years. They were examined by US and findings were correlated with MRI.Results
US was capable to detect various lesions (synovitis, arthritis, plantar fasciitis, tendon and ligamentous lesions). It had a sensitivity of 95.4%, a specificity of 83.3% and an overall accuracy of 92.8%. US had a limited value in detection of avascular necrosis (AVN), bone marrow oedema and fractures.Conclusion
US can be used as a first step diagnostic tool in cases of ankle pain. MRI should be spared to cases with negative or equivocal US findings. 相似文献14.

Background
MRI is an essential tool for diagnosing multiple sclerosis; however, overlap with nonspecific white matter lesions still exists. The central vein sign as detected by MR susceptibility weighted imaging has been proposed to improve the diagnostic accuracy of MRI in MS.Purpose
To assess the value of the central vein sign at susceptibility weighted imaging in discriminating between MS-WMLs and leukoaraiosis-WMLs.Patients and methods
Thirty MS patients and 30 patients with leukoaraiosis, matched for age and gender were included in this study. On axial FLAIR, white matter lesions?≥?5?mm were counted and subsequently assessed on the axial SWI sequence for the presence of the central vein. The cut-off value of CVS positivity of lesions was evaluated using ROC curve.Results
CVS was detected in 86.84% of MS lesions and in 13.33% of leukoaraiosis lesions with statistically significant difference.The sensitivity, specificity, positive and negative predictive values of individual CVS positive lesion in diagnosing MS were 86.84%, 86.6%, 88.7% and 75.72% respectively. A specificity of 100% was attained when CVS positive lesion load is ≥47.5%.Conclusion
Central vein sign is a fairly reliable discriminator between MS and leukoaraiosis. 相似文献19.
