Objective To summarize the examination results of coronary artery by electron beam computed tomography angiography(EBCTA) and analyze the relationship of electrocardiographic(ECG) triggering phase and image quality.
MethodsSixteen cases of PA/IVS were analyzed retrospectively, including X ray chest film, echocardiography, right cardiac catheterization, and angiocardiography. Two patients underment electronic beam CT (EBCT) scanning.
Electron beam computed tomography (EBCT), a non-invasive imaging method with very high spatial and temporal resolution, is well suited for cardiac imaging.
Electron beam computed tomography (EBCT) allows viszalization and quantification of calcium in the coronary arteries.
X-ray computed tomography (CT) has exhibited rapid technological advances in recent years which has made it a potential alternative to electron beam computed tomography (EBCT).
Although electron beam computed tomography can accurately locate calcification patterns within the coronary tree in a non-invasive manner, it's often difficult to know the extent of calcification and the relationship to fibrofatty plaques.
Electron beam computed tomography: calcification and lipid lowering interventions
Electron beam CT measures coronary calcium quickly, easily, accurately, and with a high degree of reproducibility.
In symptomatic persons undergoing cardiac catheterization, electron beam CT is more closely associated with the severity of coronary atherosclerosis than are standard coronary risk factors.
The diagnosis of PE was assumed on the basis of a mismatch at V/Q scanning or a filling defect in a pulmonary vessel at contrast-enhanced electron beam CT.
In 37/45 patients (24 female, 21 male, 58±16 years) with suspected PE, the diagnosis of PE was confirmed or excluded by both modalities, resulting in a correlation of 82% between electron beam CT and V/Q scanning.
Of these 504 segments, 248 (nearly 50%) showed perfusion defects on V/Q scans, of which only 90 (36%) displayed emboli at electron beam CT.
For the preoperative diagnosis, an ultrafast-CT (Electron Beam Tomography, EBT) was done, as neither the pseudoaneurysm, nor the venous graft could be visualized by selective coronary angiography.
The detection and quantification of coronary calcifications by electron beam tomography (EBT) permits to diagnose coronary atherosclerosis in an early stage.
Electron beam tomography as an endpoint for clinical trials of antiatherosclerotic therapy
With electron beam tomography imaging the coronary artery tree is visualized noninvasively and vascular calcification, a marker of atherosclerotic disease, is easily detected and its extent quantified.
