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.

VIDEO: Use of CT to assess coronary plaques

Leslee Shaw, PhD, director of The Blavatnik Family Women’s Health Research Institute, Mount Sinai Hospital, New York, explains how cardiac computed tomography (CT) can be used to assess coronary plaques.

COVID-19 vaccine associated myocarditis on short-axis 1.5T MRI images of a 19-year-old man who presented with chest pain three days following the second dose of an mRNA COVID-19 vaccine.

New cardiac MRI analysis offers updated insight into long-term impact of vaccine-related myocarditis

Months after their initial myocarditis diagnosis, late gadolinium enhancement (LGE) was observed in 62% of patients on follow-up cardiac MRI.

Study urges radiologists to report CAC findings on all chest CTs, regardless of clinical indication

Although current guidelines recommend radiologists evaluate CAC on all non-gated, non-contrast chest CT scans, the authors of the study note that these guidelines are not consistently followed.

Statin reduces risk for non-obstructive CAD patients but no significant risk reduction for aspirin

The results of a study published in Radiology: Cardiothoracic Imaging call into question the value of initiating aspirin therapy in certain instances.

Heartflow FFR-CT allows noninvasive assessment of a patient'c coronary arteries without the need for a diagnostic angiogram.

VIDEO: HeartFlow FFR-CT sees increased interest after inclusion in the 2021 Chest Pain Guidelines

HeartFlow’s non-invasive cardiac computed tomography derived fractional flow reserve (FFR-CT) technology enables FFR values for the entire coronary tree of a patient using just a CT scan. This can show the significance of any coronary plaque lesions and if a patient needs to be sent to the cath lab for revascularization, or if they can be treated medically.
