Cardiac CTA is also a useful alternative to invasive coronary angiography for pre-operative evaluation of persons undergoing non-coronary cardiac surgery or high-risk non-cardiac surgery, where invasive coronary angiography would otherwise be indicated. Einstein and colleagues (2007) ascertained the lifet...
However, current literature does notprovide sufficient evidence to support a role for CTA in any other CAD population. The literature does notsupport its use as a screening tool.1Policy Number: HS
the focus is not on the lungs, but on a person’s heart. A doctor might order a cardiac CT to detect problems with the aorta, heart valves and other arteries. In some cases, a doctor might order a cardiac CT scan to follow up on the results of a procedure, such as coronary artery...
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 in the blood vessels. What is the differen...
the catheterization procedure; 2) the contrast dose for an ACT acquisition is less than or equal to that used for MSCT; and 3) the generated images can be immediately and accurately registered with real-time fluoroscopy to serve as a 3D overlay roadmap in the cardiac catheterization laboratory...

The SOMATOM Force’s fastest rotation speed is 4 rotations per second or 0.25 seconds per rotation, which equals a temporal resolution of 66 ms in cardiac imaging – independent of the heart rate. The extended coverage of the SOMATOM Force means an entire heart can be covered in approximately...

Fourth, the applicability of this method is lim- ited to procedure rooms equipped with hybrid angio/ CT system. Although the install base of angio/CT equipment in interventional radiology practice has seen a recent uptick, its current availability is widely lim- ited to major academic ...
17 Image Acquisition and Analysis for ICA Selective ICA was performed by standard protocol, with a minimum of 2 projections obtained per vessel distribution and with angles of projection optimized based on the cardiac position.18 Invasive coronary angiograms were transferred to a central angiographic ...
