CT Angiography (CTA)

This channel includes news and new technology innovations for CT systems use a series of X-ray images to create an image volume datasetthatcan slices 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.

Dianna Bardo, M.D., oversees a pediatric CT scan at Phoenix Children’s Hospital. She uses technology to help lower CT X-ray radiation dose when scanning children.

The CT scanner might not come with protocols that are adequate for each hospital situation so at Phoenix Children’s Hospital they designed their own protocols, said Dr. Dianna Bardo, director of body MR and co-director of 3D Innovation Lab at Phoenix Children’s. She said they shared these protocols as part of their partnership with Philips Healthcare.

An example of a real-time patient radiation dose tracking system available for Canon's angiography imaging system. Systems like this can show cumulative dose to the patient's skin as a reminder to rotate the C-arm to new positions to prevent burns during long procedures. These types of systems also can help track patient dose and the location of that dose to be included as part of their electronic patient record. This data also enables quality assurance assessments.

A patient injuried by extreme exposure to X-ray radiation during an angiography procedure, which is included among the images in the American College of Cardiology (ACC) consensus document. Angiography skin burn.

A patient injured by extreme exposure to X-ray radiation during an angiography procedure, which is included among the images in the consensus document. Severe skin injury typically appears four to eight weeks following the exposure. In extreme cases, the ulceration can become confluent and full thickness necrosis of skin may develop, exposing underlying fat, muscle and even bone.
