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.

A dedicated Cardiac MRI scanner. The presence of myocardial fibrosis on cardiac MRI can help anticipate adverse arrhythmic events and  may offer a way to improve patient selection for cardiac implantable electronic devices (CIEDs). This is a dedicated cardiac MRI system at Baylor Scott White.

Could cardiac MRI become the reference standard for diagnosing heart failure?

Cardiac MRI may offer a more accurate and less invasive method for diagnosing heart failure, a new study published in the European Heart Journal shows.

FDA clears spinal-tap test that could challenge PET in Alzheimer’s diagnostics

The FDA has approved a lab test for evaluating cognitively impaired adults who may be in the early stages of Alzheimer’s disease.

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.

Foot ultrasound bested foot MRI on pooled sensitivity while lagging on specificity

MRI beats ultrasound at grading common foot injury, but tables turn for up-or-down diagnostics

Injuries of the plantar plate—the cluster of ligaments underneath the four smaller “knuckles” of the toes—are better assessed with MRI than with ultrasound scans.

Cardiac implantable electronic devices can be safely reprogrammed to MRI-safe mode via remote operator

In 209 study participants, the remote reprogramming resulted in a successful, event-free MRI scan for every patient.
