PURPOSE To directly compare the sensitivity of 64-section multidetector computed tomography (CT) with that of 1.5-T magnetic resonance (MR) imaging in the depiction and measurement of heterogeneous 7-8-week-old microinfarcts and the quantification of regional left ventricular (LV) function and perfusion in the territory of coronary intervention in a swine model. MATERIALS AND METHODS Approval...

PURPOSE To retrospectively assess the value of computed tomographic (CT) bronchial arteriography (BA) with 320-row multidetector CT in the management of patients with recurrent hemoptysis immediately after bronchial artery embolization (BAE). MATERIALS AND METHODS Among 135 consecutive patients treated with BAE between April 2014 and March 2016, recurrent hemoptysis developed in 15, and 10 su...

PURPOSE To evaluate multidetector computed tomographic (CT) images to investigate the prevalence, morphology, natural course, and prognostic effect of intramural blood pools (IBPs) in patients with acute intramural hematoma (IMH). MATERIALS AND METHODS Institutional review board approval and written informed consent were obtained. Sixty-five patients (41 men; mean age, 65.9 years ± 11.3 [stan...

conclusions a high index of suspicion is essential for early detection of ddr and dddr. patients with high impact injuries or surrounding organ damage should be followed with serial clinical examinations, follow-up radiologic assessments, and even re-exploration in situations highly suspicious for diaphragmatic injuries. introduction diaphragmatic rupture (dr) is an uncommon, potentially seriou...

PURPOSE To assess the potential of a single-session multidetector computed tomography (CT) protocol, as compared with established methods, for the etiologic work-up of acute ischemic stroke. MATERIALS AND METHODS Patients found to have recently experienced an ischemic stroke were recruited for this prospective study after institutional review board approval was obtained. Each patient was sche...

BACKGROUND AND PURPOSE Several retrospective studies suggested that contrast extravasation on CT angiography predicts hematoma expansion, poor outcome, and mortality in primary intracerebral hemorrhage. We aimed to determine the predictive value of contrast extravasation on multidetector CT angiography for clinical outcome in a prospective study. METHODS In 160 consecutive patients with spont...

BACKGROUND The accuracy of multidetector computed tomographic (CT) angiography involving 64 detectors has not been well established. METHODS We conducted a multicenter study to examine the accuracy of 64-row, 0.5-mm multidetector CT angiography as compared with conventional coronary angiography in patients with suspected coronary artery disease. Nine centers enrolled patients who underwent ca...

BACKGROUND Preoperative imaging has been demonstrated to improve diagnostic accuracy in appendicitis. This prospective study assessed the accuracy of a diagnostic pathway in acute appendicitis using ultrasonography (US) and complementary contrast-enhanced multidetector CT in a general community teaching hospital. STUDY DESIGN One hundred fifty-one patients with clinically suspected appendicit...

The accuracy of computed tomography (CT) imaging for the diagnosis of acute pulmonary embolism (PE) was reviewed. Single detector CT, based on pooled data, showed a sensitivity of 73% and multidetector CT, mostly 4-slice, showed a sensitivity of 83%. Respective specificities were 87% and 96%. Among patients with suspected PE evaluated with single slice CT, 20% of patients found to have venous t...
