A deep neural network platform can help radiologists detect abdominal aortic aneurysms (AAAs) on CT images, and is especially helpful in clinically challenging cases, according to research presented at the SIIM annual conference.

Positron emission tomography/computed tomography (PET/CT) shows a strong correlation between severe obstructive sleep apnea (OSA) and impaired coronary flow, making it an important tool for helping to avert cardiac complications that occur when OSA is left untreated.

A 40-minute MRI scan to test for angina can spare patients from invasive angiography along with an overnight stay in the hospital, according to a recent study published in the New England Journal of Medicine.

“Although echocardiography plays an important role in the treatment of many patients with AMI, these findings suggest that a more selective approach may be safe and may reduce costs, particularly at high-use hospitals,” wrote authors of a new study published in JAMA Internal Medicine.

Coronary artery calcium (CAC) levels spotted on CT scans in middle-age patients were connected to an increased risk of structural heart abnormalities indicative of future heart failure, according to a new study published in Circulation: Cardiovascular Imaging.

 

Cardiac MRI can detect cocaine’s impact on the cardiovascular system and help differentiate between a wide range of heart diseases, according to a new literature review study published in Radiology: Cardiothoracic Imaging.

Researchers created and validated a machine learning model using features taken from baseline, laboratory, electrocardiography (ECG), echocardiography and cardiovascular resonance (CMR) imaging data.

Fractional flow reserve derived from CT (FFR-CT) is a superior predictor of long-term outcomes of heart disease compared to traditional coronary CT angiography (CCTA), according to a new study published in Radiology.

Experts have theorized that ultra-marathon runners may face negative cardiovascular changes due to their extreme training methods. A team of Polish-led researchers used cardiovascular MR (CMR) to investigate this, publishing their findings in the European Journal of Radiology.

It can be hard for physicians to identify the damaged artery responsible for a non-ST segment elevation myocardial infarction (NSTEMI). Typically coronary angiography is the first choice, but is it the best?

The new method—cardiac functional MRI (cfMRI)—measures how the heart utilizes oxygen for both healthy patients and those with a form of heart disease.

Deep learning designed to read single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) can improve the diagnosis of coronary artery disease—a killer of more than 370,000 people in the U.S. annually.
