Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

An example of HeartFlow's FFR-CT technology, which takes the cardiac CT dataset and uses computational fluid dynamics to create virtual fraction flow reserve values. The FFR measurement can help determine if a coronary lesion is significant enough to require revascularization, or if the patient should be treated with medication. FFR-CT was included as a recommendation in select patients in the 2021 Chest Pain Guidelines.

Researchers question FFR-CT’s value compared to other cardiac imaging options

FFR-CT has grown in popularity due its ability to provide noninvasive evaluations of patients being considered for revascularization procedures. According to a new study in JACC: Cardiovascular Imaging, however, stress imaging strategies may still provide more value in certain scenarios.

Brain imaging artificial intelligence is a primary area of concentration for AI because oif the critical nature of fast detection and treatment for patients. This is an example of the AI applications displayed by third-party advanced visualization vendor TeraRecon at RSNA 2022.

What is the ROI on AI adoption in radiology?

Radiology makes up the vast majority of FDA-cleared AI algorithms, but with minimal or no reimbursement, hospital administrators may ask whether AI’s value justifies its expense.
