An 83-year-old woman presented to the emergency department with a 2-hour history of sudden chest pain and dyspnea. An initial ECG demonstrated nonspecific ST changes, and a portable chest x-ray suggested a widened mediastinum. A thoracic multidetector helical computed tomography (CT) angiogram was obtained to assess the possibility of aortic dissection (GE LightSpeed Plus, 2.5-mm collimation wi...

Evaluation of a body mass index-adapted protocol for low-dose 64-MDCT coronary angiography with prospective ECG triggeri...

Prompt diagnosis of acute mesenteric ischemia is a dilemma which is unfortunately generally made at the irreversible phase of intestinal damage. Besides conventional diagnostic imaging modalities contrast enhanced multidetector computed tomography angiography enables fast and detailed evaluation of the mesenteric circulation and abdominal viscera which provides accurate and rapid diagnosis in t...

OBJECTIVE To assess the prognostic role of multidetector computed tomography coronary angiography (MDCT-CA) in patients with diabetes with suspected coronary artery disease (CAD). Use of MDCT-CA is increasing in patients with suspected CAD. However, data supporting its prognostic value in patients with diabetes are limited. RESEARCH DESIGN AND METHODS Between January 2006 and September 2007, ...

OBJECTIVE To present a case of a rare variation of the renal artery and multiple (7) renal arteries by multidetector computed tomography (MDCT) angiography. CLINICAL PRESENTATION AND INTERVENTION A 36-year-old male patient was admitted to our hospital as a potential living donor for renal transplantation. An MDCT angiography was performed using a 16-detector row CT scanner to obtain a detaile...

results of this study suggested superiority of CABG over PCI in elderly patients, this is counterintuitive and these results may not be generalizable to the majority of patients requiring coronary revascularization. Those patients with a higher risk profile were likely to be excluded from randomization because of procedural risks associated with CABG (3). The advantage of PCI in the elderly pat...

OBJECTIVE To assess the performance of multidetector computed tomography in determining late clinical outcomes of patients undergoing sirolimus-eluting stent implantation. METHODS Thirty patients, successfully submitted to sirolimus-eluting stent implantation for more than six months, were selected to participate in the study. All underwent invasive angiography and intravascular ultrasound fo...

background: coronary computed tomography angiography (ccta) is a well-known method for evaluating anatomic coronary stenosis, but the reliability of ccta to predict cardiovascular events is an issue of controversy. materials and methods: in this prospective observational study, 58 patients with acute chest pain and low-to-moderate risk were selected and ccta was performed on them. during follow...
