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.

The inherent spectral capabilities of Mayo Clinic's new third-generation photon-counting CT research scanner allows clear visualization of the intact portions of the coronary artery lumen (arrowhead) by reducing the bright signal from the dense coronary calcifications (arrows).

The inherent spectral capabilities of Mayo Clinic's new third-generation photon-counting CT research scanner allows clear visualization of the intact portions of the coronary artery lumen (arrowhead) by reducing the bright signal from the dense coronary calcifications (arrows). Spectral CT is able to bin photos on different energies that can be used to enhance or subtract chemical elements from the images based on their spectral signature, such as calcium shown here, and iodine.

An example of how spectral CT can help aid diagnosis in a pancreatic CT which may have a small lesion, but it is difficult to see. The dual-energy imaging clearly shows a lesion. This is example is from the Philips Spectral CT 7500 system.

While the COVID-19 crisis is challenging, the pandemic is also giving researchers an opportunity to discover new approaches to saving lives. A study published in the JAMA Network Open on Thursday, March 25, 2021, recommends a new way for triaging mammogram patients during times of limited capacity, such as pandemic surges, when individuals may also experience anxiety about COVID-19.

An example of a HeartFlow FFR-CT image showing the blood flow through what looked like a significant blockage on CT angiography alone, actually was not flow-limiting based on computational fluid dynamics. Use of the technology was supposed to reduce the number of diagnostic catheterizations in the FORECAST trial, but the costs of FFR-CT were not offset enough to show cost savings.
