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.

MRI shows liver fibrosis may be linked to cardiovascular disease

In a multiethnic cohort study published March 9 in Circulation: Cardiovascular Imaging, researchers found liver fibrosis may be strongly associated with a patient's history of heart failure, atrial fibrillation or coronary heart disease.

New quantitative flow ratio method tops FFR in diagnosing heart blockages

A team of international researchers showed that quantitative flow ratio (QFR) was feasible for testing coronary artery stenosis, and more accurate compared to traditional wire-based fractional flow reserve (FFR), according to a study published in Circulation: Cardiovascular Imaging.

Infarction patterns determine benefit of dual antiplatelet therapy for stroke patients

Patients with multiple acute infarction patterns may benefit the most from dual antiplatelet therapy compared to others who have experienced a minor stroke, according to a recent study of imaging data published online March 26 in the Journal of the American Medical Association.

New method may improve fractional flow reserve CT accuracy

A recent study published in the April 2018 issue of Radiology optimized a four-step approach to accurately detect hemodynamically significant intermediate-stenosis lesions, which outperformed coronary CT angiography. Researchers also found using coronary contrast opacification variations to estimate blood flow distribution may improve CT fractional flow reserve accuracy.

The newly approved AI models are designed to improve the detection of pulmonary embolisms and strokes in patients who undergo CT scans.

"I see, at least for the next decade, this being a SPECT and PET world, not one or the other," explained Tim Bateman, MD.

The FDA-approved technology developed by HeartFlow can predict a patient's long-term risk of target vessel failure as well as more invasive treatments performed inside a cath lab.
