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. 

Example of a patient's coronary tree extracted from a cardiac CT scan. CT allows very detailed anatomical imaging and now physiological and plaque information that can be useful in pre-planning interventional procedures. Imaging from the GE Revolution Apex system at SCCT 2022.

VIDEO: CT imaging to plan coronary interventions — Interview with Jonathon Leipsic, MD

Jonathon Leipsic, MD, chairman of the Department of Radiology, University of British Columbia, explains how noninvasive computed tomography angiography (CTA) can be used to aid in planning interventional cardiology procedures for percutaneous coronary intervention (PCI) and chronic total occlusions (CTO).

Former European Society of Cardiology president Prof. Jeroen Bax explains the difficulty in quantifying these plaques manually and how artificial intelligence may change this to allow rapid, detailed quantitative analysis.

Cardiac CT soft plaque assessment may offer paradigm shift for coronary disease screening

New artificial intelligence software that can evaluate coronary CT scans to automatically assess soft plaques were by far the biggest technology advance discussed at the Society of Cardiovascular Computed Tomography (SCCT) 2022 meeting.

Eric Williamson, MD, MSCCT, the 2021-2022 president of the Society of Cardiovascular Computed Tomography (SCCT) and professor of radiology at Mayo Clinic, shared his key takeaways from the SCCT 2022 conference. 

Examples of new plaque reporting in the CAD-RADS 2.0 document. Left, an example from CAD-RADS 2 / P2 plaque burden with mild coronary stenosis (25-49%). Right, example of a CAD-RADS 5/ P3, with a focal, non-calcified occlusion of the proximal RCA (arrow) and severe amount of plaque (P3). #CADRADS #YesCCT #CTA #CCTA

New CAD-RADS 2.0 reporting for coronary CTA offers patient management recommendations

The document includes updated classification to established a framework for stenosis, plaque burden and plaque modifiers, including assessment of CT-FFR or myocardial CT perfusion.

Big private payer reverses course on cardiac PET/CT coverage

One of the largest private health insurers in the U.S. has gone from considering hybrid PET/CT for cardiac indications “experimental/investigational” to displaying willingness to pay for the modality.

Cardiologists push back on FDA’s thyroid monitoring/contrast media proposal

According to a new SCAI statement, the FDA's recommendation would result in "far-reaching consequences" across multiple specialties. 

The American Medical Association (AMA) Board of Delegates approved a policy calling on payers to reimburse for the drug regadenoson and not to employ payment policies that push for cardiologists to change the drug they use for pharmacologic stress for one that is considered less safe. The policy was adopted at the AMA 2022 meeting. #AMA #AMA175 #AMAmtg #ASNC

AMA supports reimbursement for pharmacologic stress agent regadenoson

The American Medical Association Board of Delegates approved a policy calling on payers to reimburse for the drug regadenoson and not to employ payment policies that push for cardiologists to change the drug they use for pharmacologic stress for one that is considered less safe.

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.
