Recent developments in computed tomography technology have made imaging of the coronary arteries possible. All the same, the rapid motion and small dimensions of the coronary vessels make coronary computed tomography angiography (coronary CTA) challenging. With the last generations of 16- and 64-slice computed tomography and adequate patient preparation (which includes lowering of the heart rat...

Coronary computed tomographic angiography (cCTA) as a noninvasive approach underlies a rapid technological development with an impressive improvement of spatial and temporal resolution of the images. Therefore, it has become an accurate and costeffective method to detect or exclude obstructive coronary artery disease (CAD) in patients with low to medium cardiovascular risk profile, as recommend...

O ne million patients undergo invasive coronary angiogra-phy (CA) in the United States every year. 1 In view of its invasive nature and related costs, noninvasive imaging of coronary imaging has the theoretical appeal to improve comfort for patients, reduce cost, and refine patient selection to limit invasive procedures to patients requiring treatment for ischemic coronary artery disease (CAD)....

Background: This study assessed the application value of 64-slice spiral computed tomography angiography (CTA) in a follow-up evaluation of patients receiving coronary stent implantation. Materials and Methods: A total of 468 patients who underwent percutaneous coronary intervention (PCI) at our hospital between January 2013 and October 2016 were selected for this study. Coronary angiography an...

Feasibility study of the best monitoring time-interval to track contrast agent bolus in dual-source coronary computed tomography angiography

conclusions coronary artery aneurysm should be a differential diagnosis in cases of mediastinal cyst and mass lesion. case presentation a 32-year-old woman presented with edema of the upper and lower limbs, palpitation, and chest pain, and was diagnosed with a giant right coronary artery aneurysm that had initially mimicked a mediastinal cyst. although computed tomography (ct) suggested a media...
