Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT.

CMR helps hone treatment for recurrent pericarditis

Cardiac MR (CMR) can help guide therapy in patients with recurrent pericarditis. One center reported patients who underwent imaging received a smaller total dose of steroids and experienced fewer recurrences than patients who did not get scans.

Intra-arterial therapy shines in MR CLEAN stroke trial

Giving patients with certain acute ischemic strokes intra-arterial treatment in addition to tissue plasminogen activator led to better outcomes compared with usual care, MR CLEAN researchers reported online Dec. 17 in the New England Journal of Medicine.

CCTA races past treadmill ECG for cost, performance

Coronary CT angiography (CCTA) saves time and money compared with exercise treadmill tests for assessing low- to intermediate-risk patients who present with chest pain. In a randomized trial, CCTA also performed better diagnostically.

MR perfusion looks even better for detecting CAD

Myocardial MR perfusion may deserve a place in clinical practice for assessing patients for coronary artery disease (CAD). Using a gold standard as reference, researchers gave MR perfusion’s diagnostic ability high marks.

CMR verified myocarditis leads to lower EF at 12 months

In a small group of patients, cardiovascular magnetic resonance (CMR) imaging provided clues to myocarditis diagnosis and outcomes.  Positive “Lake Louise criteria” (LL) was associated with improved left ventricular function recovery, while patients with a negative LL still had lower ejection fraction (EF) at 12 months.

AliveCor launches new app to auto detect atrial fibrillation in an ECG recording

AliveCor, Inc. announced today the launch of the latest version of the AliveECG app, which provides patients with free real-time atrial fibrillation (AF) detection in ECG recordings using its new FDA-cleared algorithm. The new app helps patients and physicians manage existing conditions with intelligent, personalized and easy-to-use new features.

CT-based Mobile Stroke Care

Germany's ground-breaking use of CT scanners in ambulances to assess for possible stroke inspired one program in Houston to follow suit. Supporters predict it will transform care in the future. 

AliveCor receives first FDA clearance to detect a serious heart condition in an ECG on a mobile device

AliveCor, Inc. announced today that the U.S. Food and Drug Administration (FDA) has granted the company clearance for its algorithm to detect atrial fibrillation (AFib), the most common form of cardiac arrhythmia. 

Around the web

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.
