Cardiac MRI

CT angiography and SPECT myocardial perfusion imaging improves with the use of synchronized multimodal heart visualization software.

Using CT to measure coronary artery calcium may aid physicians in predicting the chances of incident cardiovascular events.

Cardiologists should review cardiac imaging use for their patients in an effort to reduce patient radiation exposure.

PET-CT with the radioactive tracer 18F-NaF PET-CT helps clinicians detect ruptured and high-risk coronary plaques.

A new technique, quantitative T1 mapping with cardiovascular MRI, can help clinicians detect Fabry disease and the severity of heart damage.

Low-dose ionizing radiation from cardiac imaging after heart attack poses a greater cancer risk for women than men.

Transthoracic echocardiography results do not frequently change active treatment among patients.

CT scans of mummies show that plaque build-up and clogged arteries occurred among people 4,000 years ago, as well as today.

Most men with small abdominal aortic aneurysms, 3.0 cm to 5.4 cm, could be safely monitored with ultrasound at longer intervals.

Imaging the loss of nerve function in the heart may better identify patients who would benefit from receiving implantable cardiac defibrillators (ICD) than current testing methods.

PET imaging agent CardioGen-82 is returning to the U.S. market with a revised label warning of unintended radiation exposure risk.

The problems lead to unexpectedly high patient radiation exposure and voluntary recall of the PET imaging agent.

Bracco Diagnostics expects a “limited and progressive reintroduction” of its CardioGen-82 PET tracer in the first or second quarter of 2012, the company said in an Oct. 17 letter to customers.

The FDA issued a warning about the potential for inadvertent, increased radiation exposure in patients receiving cardiac PET scans with Rb-82 chloride injection from CardioGen-82.

The U.S. Food and Drug Administration has announced a recall of 110,000 iCross and as Atlantis SR Pro 2 coronary imaging catheters. This follows Boston Scientific’s voluntary recall of iCross catheters announced on May 27.

A Monday morning scientific session covering cardiac CT dose and noise broke down into newsworthy matched pairs: two studies examining the implication of CT radiation on public health, two investigating the impact of radiation reduction strategies on patient dose and image quality, and a third pair considering how noise reduction from iterative reconstruction affects the quality of images of highly calcified vessels and morbidly obese patients.

Radiologists can predict cardiovascular disease using incidental findings from routine diagnostic CT, according to a study appearing in Radiology.

Typically when someone presents to the emergency department with acute chest pain, the patient is admitted for further workup.

Experts have long suggested that the clinical promise of 3T, with its improved signal-to-noise ratio compared with 1.5T, might eventually be expressed in cardiac imaging, one of the least approachable clinical areas of MR.

MRI was able to reveal changes to the heart and vessels of athletes who trained for triathlons, according to research conducted at the University of Erlangen- Nuremburg in Germany.

Stress cardiac MRI reduced incident cost without missing any acute coronary syndrome cases in patients with chest pain at a North Carolina facility.

An x-ray taken centuries after her death proves a well-known saint died from a cardiac embolism instead of tuberculosis, as was previously thought. The body of Santa Rosa, an 18- or 19-year old girl, was naturally mummified in the 13th century.

A new SPECT cardiac imaging system that uses a cadmium zinc telluride-based high-speed, high-resolution camera dramatically reduces imaging time for patients while also reducing radiation exposure.

Computer-aided detection software developed especially for coronary CT angiography could boost imagers' ability to rule out clinically relevant stenosis in patients at low to moderate risk of coronary artery disease, according to researchers at the Medical University of South Carolina.

Electrocardiogram-gated tube modulation is essential to lower radiation dose in fusion imaging.

Coronary artery calcium scanning predicts the risk of myocardial infarction and sudden death accurately enough to guide the selection of diagnostic tests for symptomatic patients, according to a multicenter prospective study.

Increasing CT scanning speeds and image resolution combined with automated injection and optimized protocols tailored to specific patient features could reduce iodinated contrast media needed for coronary CT angiography by at least half, according to several papers presented at the 2009 RSNA meeting.
