Evaluation of a Chest Circumference-Adapted Protocol for Low-Dose 128-Slice Coronary CT Angiography with Prospective Electrocardiogram Triggering
OBJECTIVE To assess the effect of chest circumference-adapted scanning protocol on radiation exposure and image quality in patients undergoing prospective electrocardiogram (ECG)-triggered coronary CT angiography (CCTA). MATERIALS AND METHODS One hundred-eighty-five consecutive patients, who had undergone prospective ECG triggering CCTA with a 128-slice CT, were included in the present study....

AIMS To evaluate the accuracy of low-dose computed tomography coronary angiography (CTCA) using prospective ECG-triggering for the assessment of coronary artery disease (CAD). METHODS AND RESULTS A total of 30 patients (19 males, 11 females, mean age 58.8 +/- 9.9 years) underwent low-dose CTCA and invasive coronary angiography (CA) [median 2 days (0, 41)]. Before CT scanning, intravenous beta...

omputed tomography for coronary angiography (CTCA) as rapidly evolved into a valuable alternative to invasive oronary angiography for accurate noninvasive assessment f coronary morphology. Although increasing values of ositive predictive values are continuously reported, it is enerally accepted that the strength of this technology at resent lies in its excellent ability to exclude coronary arte...
متن کاملFirst head-to-head comparison of effective radiation dose from low-dose 64-slice CT with prospective ECG-triggering versus invasive coronary angiography.
BACKGROUND Reduction of radiation burden of multidetector computed tomography coronary angiography (CTCA) has remained an important task. OBJECTIVE To compare effective radiation dose of low-dose 64-slice CTCA using prospective ECG-triggering versus diagnostic invasive coronary angiography (CA). METHODS 42 patients referred for elective invasive CA owing to suspected coronary artery disease...
