a 3 month- old boy was admitted with recurrent severe respiratory distress and refractory to therapeutic options. patient underwent a helical multidetector ct examination. axial, coronal and three- dimensional imaging, revealed tracheal bronchus, stenosis, diverticulum and bronchiectasis. in this situation, ct scanning, perfectly 3d imaging is recommend for rule out congenital tracheobronchial ...

OBJECTIVE To examine whether we could predict myocardial ischemia when coronary artery calcification is detected by non-gated multidetector CT in patients with suspected ischemic heart disease. METHODS Eighty-three patients suspected of having ischemic heart disease (55 men, 28 women; age range 36-83 years; mean age 68 years) underwent multidetector CT and T1-201 single photon emission comput...

PURPOSE To retrospectively assess virtual autopsy performed with multidetector computed tomography (CT) for the forensic evaluation of gunshot wound victims. MATERIALS AND METHODS The institutional review board approved this HIPAA-compliant study and did not require informed consent of the next of kin. Thirteen consecutive male gunshot wound victims (mean age, 27 years) were scanned with 16-s...

BACKGROUND AND PURPOSE Perfusion imaging in the angiography suite may provide a way to reduce time from stroke onset to endovascular revascularization of patients with large-vessel occlusion. Our purpose was to compare conebeam CT perfusion with multidetector CT perfusion. MATERIALS AND METHODS Data from 7 subjects with both multidetector CT perfusion and conebeam CT perfusion were retrospect...

Sixteen-slice multidetector CT findings of a pulsatile pseudoaneurysm of the mitral-aortic intervalvular fibrosa, in a woman following aortic valve replacement, are presented. Multidetector CT depicted the pseudoaneurysm and enabled dynamic evaluation of its lumen through the cardiac cycle, documenting expansion during systole and almost complete collapse during diastole. This case illustrates ...

STUDY OBJECTIVE We compared the accuracy of multidetector computed tomography (CT) coronary angiography with stress nuclear imaging for the detection of an acute coronary syndrome or 30-day major adverse cardiac events in low-risk chest pain patients. METHODS This was a prospective study of the diagnostic accuracy of myocardial perfusion imaging and multidetector CT in low-risk chest pain pat...

The study of fossils permits the reconstruction of past life on our planet and enhances our understanding of evolutionary processes. However, many fossils are difficult to recognize, being encased in a lithified matrix whose tedious removal is required before examination is possible. The authors describe the use of multidetector computed tomography (CT) in locating, identifying, and examining f...

methods multidetector ct-scan and explorative laparotomy of the patients with blunt abdominal trauma were assessed retrospectively. characteristics of the injuries were categorized on the basis of the american association for the surgery of trauma (aast) grading system and the findings were analyzed using kappa test. results the findings of 35 patients were analyzed. according to the kappa test...

OBJECTIVES To assess the role of multidetector computed tomography (CT) and CT virtual sinoscopy in the evaluation of chronic sphenoid sinusitis and to compare the imaging findings with functional endoscopic sinus surgery. DESIGN Prospective study. SETTING Tertiary care teaching hospital. PATIENTS Thirty patients with chronic sphenoid sinusitis referred for preoperative CT. INTERVENTION...

OBJECTIVE. The objective of our study was to evaluate the role of dynamic inspiratory– expiratory imaging with multidetector CT in patients with suspected tracheobronchomalacia. CONCLUSION. Multidetector CT with inspiratory–expiratory imaging is a promising method in the evaluation of patients with dynamic airway collapse. In our study, the degree of dynamic collapse correlated well with bronch...
