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.

MRI in patients with abandoned pacemaker and ICD leads

Abandoned metal wire leads for pacemakers and ICDs did not present a serious safety issue in a study of 80 patients, but a handful of patients did experience a significant change in the composite of capture threshold, sensing or lead impedance.

The American Society of Nuclear Cardiology (ASNC) is asking Congress to repeal the appropriate use software provision mandate, which physicians say is an obstacle to efficient care.

Medicare rescinded the provision in the 2024 Medicare Physician Fee Schedule, but the law remains on the books. 

HeartFlow introduced its next generation artificial intelligence (AI) Plaque Analysis with an interactive experience at SCCT 2024. It shows a 3D plaque model and analysis by territory across calcified, non-calcified and low-attenuation plaques. This includes viewing cross-sectional, color-coded images of each plaque type where it was quantified along the vessel. #SCCT #SCCT24 #SCCT2024

Updated HeartFlow technology offers interactive features, full integration with FFR-CT 

HeartFlow is using SCCT 2024 to introduce the world to its updated Plaque Analysis platform. “Accurately diagnosing a patient’s risk for coronary artery disease is critical for determining the best treatment," Chief Medical Officer Campbell Rogers, MD, explained.

How the proposed Medicare Physician Fee Schedule could impact nuclear cardiology

The American Society of Nuclear Cardiology explored some key points included in the 2025 Medicare Physician Fee Schedule proposed rule.

SCCT aims to provide common language for CCTA use with updated guidance

The Society of Cardiovascular Computed Tomography has developed a new expert consensus document designed to get physicians on the same page when discussing this growing technology. 

Emily Lau, MD, Mass General Hospital, discusses sex differences in cardiovascular presentations of women.

CVD presents differently in women than it does in men—guidelines should reflect that

Emily Lau, MD, a women's health expert with Massachusetts General Hospital, thinks major changes are needed in how we diagnose CVD in women. "Our guidelines need to be more precise and offer sex-specific recommendations," she says.

Blood pressure drug could make leukemia more responsive to chemotherapy

“This finding shows great potential to enhance the success of chemotherapy while protecting the heart," one researcher said. 

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.
