Evaluation of subsecond gated helical CT for quantification of coronary artery calcium and comparison with electron beam CT.
OBJECTIVE Since its introduction early in the 1990s, helical CT has become the predominant technology for obtaining CT images for medical applications. Recent improvements in the temporal resolution of helical CT (subsecond) and the addition of retrospective cardiac gating are combined in this report evaluating cardiac-gated helical CT for quantifying coronary artery calcium. We compare total c...
متن کاملAssessment of vascular calcification in ESRD patients using spiral CT.
BACKGROUND Dialysis patients have increased vascular calcification of the coronary arteries and aorta by electron beam CT scan. The purpose of the present study was to utilize an alternative machine, spiral CT, to assess calcification in end-stage renal disease (ESRD) patients. METHODS Two groups of patients with ESRD were evaluated: group 1, those receiving a renal transplant (n=38); and gro...
متن کاملA pictorial review of coronary artery anatomy on spiral CT.
Coronary artery calcification quantification (scoring) has been done with electron beam CT (EBCT), but is now being done with spiral or helical CT. Many radiologists and cardiologists who do not have EBCT but do have access to spiral CT will now be able to do coronary artery calcification scoring, and will now need to know the spiral CT appearance of the coronary artery anatomy. This pictorial ...
متن کامل64-Slice spiral double-low CT to evaluate the degree of stenosis and plaque composition in diagnosing coronary artery disease
This study examined the application of 64-slice spiral double-low computed tomography (CT) to evaluate the degree of coronary artery stenosis. We examined 45 patients with coronary heart disease by 64-slice spiral double-low CT and coronary angiography (CAG) to determine CT accuracy in evaluating coronary artery stenosis. Imaging analysis from 64-slice spiral double-low CT identified 199 segmen...
