American Heart Association: Pay More Attention to Radiation in Imaging Procedures

The American Heart Association is urging physicians to better understand the risks of radiation in cardiac imaging procedures. When ordering these procedures physicians should understand the appropriate use of each procedure, the radiation dose associated with the procedure, and the risks associated with that dose. Both the risks and benefits should be fully explained and discussed […]

Wide Range of Radiation Dose in Children Undergoing Cardiac Procedures

Children with heart disease are at increased risk for developing cancer later in life due to their exposure to radiation during imaging procedures. Since an ever-growing number of children with heart disease now reach adulthood, this may become an increasingly important public health issue. A new study published in Circulation offers some reassurance in finding that […]

Patient-Centered Imaging: How Best to Communicate the Benefits and Risks of Testing


Andrew Einstein discusses his JACC paper on shared-decision making for cardiac imaging procedures that expose the patient to radiation.

ESC Spotlights Growing Problem of Radiation Exposure in Cardiology

Both medical professionals and patients have a general sense that radiation used in medical imaging and procedures carries some danger, but they often underestimate the risk. And certainly most are unaware of the increasingly large proportion of the problem occurring during cardiology procedures. “Cardiologists today are the true contemporary radiologists,” said Eugenio Picano, lead author of […]

Radiation Dose Linked to Cardiac Risk in Breast Cancer Patients

In the past, cardiovascular risk has been linked to the radiation dose received by breast cancer patients. Now, a new study published in JAMA Internal Medicine attempts to calculate the cardiac risk of breast cancer patients today undergoing current radiotherapy protocols. David J. Brenner and colleagues calculated the excess cardiac risk for 48 patients who received radiotherapy at New […]

Radiotherapy for Breast Cancer Increases Heart Disease Risk

The increased risk of radiotherapy for breast cancer seen in this NEJM study may just be the tip of the iceberg.

Pilot Study Demonstrates Feasibility of MRI-Guided Catheterization

A small pilot study has demonstrated that it may one day be possible to replace x-rays with MRI to guide some cardiac catheterization procedures. As reported in the European Heart Journal, researchers at the National Heart, Lung, and Blood institute (NHLBI) performed x-ray and MRI-guided transfemoral right heart catheterization in 16 patients (4 with shunt, 9 with […]

CT Angiography Found Less Helpful in Patients With High Calcium Scores

Computed tomography angiography (CTA) has been proposed as a less invasive method to exclude obstructive coronary artery disease (CAD), but no consensus has been achieved about its clinical role in different patient subsets. Now a new report published in JACC from the CORE-64 (Coronary Artery Evaluation Using 64-Row Multidetector Computed Tomography Angiography) study shows that CTA may not be […]

New Technique Cuts Radiation Dose of MPI SPECT by Half

A new study raises the possibility that the radiation dose for MPI SPECT imaging can be reduced by half without sacrificing image quality, according to Dr. Nili Zafrir, who presented the results of the study this week at the International Conference of Non-Invasive Cardiovascular Imaging in Amsterdam. Recently, software has become available that can reduce the […]
