Computed Tomography

Cardiac computed tomography (CT) has become a primary cardiovascular imaging modality in the past 20 years, and was recommended as a 1A recommendation in the 2021 chest pain assessment guidelines. CT calcium scoring has became a primary risk assessment for coronary artery disease and whether patients should be on statins. Coronary CT angiography (CCTA) is used to for anatomical assessment of the arteries for plaque burden and to identify areas of blockage that may cause ischemia and heart attacks. Additional use of contrast CT perfusion or fractional flow reserve CT (FFR-CT) can offer physiological information on the function of the heart. CT plays a primary role in structural heart assessments for heart valves, repair of congenital defects and left atrial appendage occlusion (LAAO) for both pre-procedure planning and procedural guidance.

HeartFlow Analysis Demonstrates Highest Diagnostic Performance for Detecting Heart Disease Compared to Other Non-Invasive Tests

PARIS, May 22, 2018 — HeartFlow, Inc. today announced new data from the PACIFIC trial showed that the HeartFlow Analysis had the highest diagnostic performance for detecting coronary artery disease (CAD), the most common form of heart disease, when compared to other commonly used non-invasive cardiac tests.

MRA vs CTA for evaluating pulmonary embolism: Does the chosen modality impact downstream imaging utilization?

MR angiography (MRA) is a relatively new alternative to CT angiography (CTA) for the evaluation of suspected pulmonary embolism (PE) and it even has one major advantage over CTA: it does not expose patients to ionizing radiation.

Non-hospital-based facilities offering cardiac imaging services a rarity in Massachusetts

In 2017, Anthem implemented a new policy that requires outpatient MR and CT scans not considered medically necessary to be completed at a freestanding imaging facility to receive coverage. This went into effect in several states, sparking its fair share of controversy along the way, and a team of Boston-based researchers wanted to know how such a policy could impact patient care in Massachusetts.

HeartFlow Enters into Licensing Agreement with Cedars-Sinai for Coronary Plaque Assessment Technology

REDWOOD CITY, Calif., March 1, 2018 — HeartFlow, Inc. today announced that it has entered into a licensing and technology transfer agreement with Cedars-Sinai in Los Angeles for AutoPlaque technology, a software tool used to detect and characterize coronary artery plaque based on coronary computed tomography angiography (CCTA) images.
