Diagnosis of ischemia-causing coronary stenoses by noninvasive fractional flow reserve computed from coronary computed tomographic angiograms. Results from the prospective multi-center DISCOVER-FLOW (Diagnosis of Ischemia-Causing Stenoses Obtained Via Noninvasive Fractional Flow Reserve) study. J Am Coll ...
What is a CT Coronary Angiogram CT scans have been used to look at various anatomic regions, but have not been useful for the heart because the heart is continuously in motion. CT is very effective in looking at “static” areas, such as the brain, abdominal cavity, and extremities. Most...
Is there an alternative to an angiogram? An alternative test,cardiac catheterization with a coronary angiogram, is invasive, has more complications related to the placement of a long catheter into the groin or wrist arteries extending all the way to the heart, and the movement of the catheter i...

What to Expect During Your CT Angiogram The exact procedure of your CT angiography will vary depending on your specific condition. Generally, you can expect the procedure to begin with a clinician placing you on the exam table and administering the contrast material through an IV in your arm or...
For DE-CTA, we used a contrast-enhanced ECG-gated coronary scan protocol with energy levels of two tube detector arrays at 140 and 100 kVp. Two kinds of acquired images were fused for the CT angiogram and further calculated to construct a perfusion map (Siemens DE Heart PBV). The compared...
