cardiovascular disease remains the principal cause of death in the modernized world.   several novel noninvasive imaging techniques have been recently developed to improve diagnosis of cardiac and coronary disease.   of these advances, multidetector computed tomographic (mdct) angiography has evolved most dramatically to transform computed tomography from a single-slice trans-axial modality to ...

background although the aim of cardiac computed tomographic angiography (cta) is to visualize the cardiac, coronary, and great vessels, portions of noncardiac structures such as lung, mediastinum, bones and abdomen are visible on the scan. some have suggested that the scans should be evaluated in all field of view. some other believe that reporting accidental findings can lead to unnecessary fo...

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...

Coronary CT angiography is widely recognised as a reliable imaging modality for the diagnosis of coronary artery disease. Coronary CT angiography not only provides excellent visualisation of anatomical changes in the coronary artery with high diagnostic value in the detection of lumen stenosis or occlusion, but also offers quantitative characterisation of coronary plaque components. Furthermore...

conclusions in most cases, the conus artery can be visualized in cardiac ct. a description of the conus artery should be a part of the standard clinical coronary ct angiography description. objectives to examine whether it is possible to visualize the conus artery in multi-slice computed tomography (ct). patients and methods in 79 consecutive patients (aged 56 ± 12.9 years; 13 women), 64-slice ...

This study was conducted on a human anthropomorphic phantom to investigate the effective dose and entrance skin dose (ESD) in selected radiosensitive organs through invasive and computed tomography (CT) coronary angiography procedures using different dose-saving techniques. The effective dose was calculated as 2.49, 3.35 and 9.62 mSv, respectively, corresponding to three coronary CT angiography...

Multislice CT angiography represents one of the most exciting technological revolutions in cardiac imaging and it has been increasingly used in the diagnosis of coronary artery disease. Rapid improvements in multislice CT scanners over the last decade have allowed this technique to become a potentially effective alternative to invasive coronary angiography in patients with suspected coronary ar...

Coronary CT angiography has been increasingly used in the diagnosis of coronary artery disease owing to rapid technological developments, which are reflected in the improved spatial and temporal resolution of the images. High diagnostic accuracy has been achieved with multislice CT scanners (64 slice and higher), and in selected patients coronary CT angiography is regarded as a reliable alterna...
