CT Angiography (CTA)

This channel includes news and new technology innovations for CT systems using a series of X-ray images to create an image volume data set that can be sliced or manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (dual souce CT), and interative reconstruction dose reduction software.

Figure 4 for the study. Images of a 65-year-old man (patient 6). (a) Cardiac MRI perfusion shows perfusion deficit of anterior/anterolateral wall attributed to left anterior descending artery/left circumflex artery (*). (b) CT coronary angiography. (c) Coronary angiography, left anterior oblique projection with caudal angulation. (d) Three-dimensional image fusion helped refine diagnosis: perfusion deficits (*) were most likely caused by narrow first diagonal branch and its first, stented side branch.

(d) Three-dimensional image fusion helped refine diagnosis: perfusion deficits (*) were most likely caused by narrow first diagonal branch and its first, stented side branch (arrowhead). Retrospectively, denoted lesion could also be found at CT coronary angiography and coronary angiography (arrowheads in b and c, respectively).

Two examples of CT myocardial perfusion (CTP) imaging assessment software. Canon is on the left and GE Healthcare is on the right. Both of these technologies have been around for a few years, but there have been an increasing amount of clinical data from studies showing the accuracy of the technology compared to nuclear imaging, the current stand of care for myocardial perfusion imaging, and cardiac MRI. #SCCT #perfusionimaging

An example of FFR-CT imaging from Beaumont Hospital in Royal Oak, Mich. The left image shows a 3D generated image of the coronary tree from a CT scan evaluated with computational fluid dynamics to determine the FFR numbers. It shows a severe restriction of the left main artery which requires a stent to revacularize. The image on the right is a comparison with the invasive angiogram from the cath lab prior to stenting.
