Utilizing an MRI scanner and software designed for the automotive and aircraft industries, researchers at the University of Wisconsin School of Medicine and Public Health have developed technology that captures 4-D  images of the entire chest, with blood flow velocity represented in color coded filaments.

The procedure has the added advantage of producing results in 10 minutes—or nine times faster than current methods—does … read more »

The latest kind of CT technology exposes patients to as much as 91 percent less radiation than standard CT scans, according to a study published in the March issue of Radiology.

Conducted by researchers at Columbia University Medical Center and the National Heart, Blood, and Lung Institute, the study focused on the newest type of CT technology, a 320-detector row … read more »

Researchers at Johns Hopkins, along with cardiologists and heart imaging specialists in eight countries, have launched a year-long study to determine the best way of tracking the earliest signs of clogged coronary arteries.

The international study will involve some 400 men and women who’ve had symptoms of coronary artery disease, such as shortness of breath, chest pain, or fatigue. All qualifiy … read more »

“For ruling out coronary artery disease, CT is more accurate than MRI,” say German researchers in a report published online in the Annals of Internal Medicine. Both CT and MRI have been considered reliable ways to rule out coronary disease  in low- to moderate-risk patients, thus making invasive and potentially risky tests unneeded.

The objective of a recent study was to compare single-source CT with dual-source CT for cardiac CTA. … read more »

MRI scans may interfere with certain cardiac pacemakers, causing inadequate or unintended stimulation of a patient’s heart, say FDA researchers. Their findings are published this week in BioMedical Engineering Online. According to the study, the problem occurs when magnetic pulses from the scan mix with electronic pulses from the pacemaker. The team evaluated the risk by measuring electronic voltage produced … read more »

When ultrasound and mammogram results prove inconclusive, can breast MRI help crack the case? That’s what researchers at New York University School of Medicine tried to find out in a study recently published in the American Journal of Roentgeneology. The scientists reviewed images done over a six-year period from 115 MRI exams, all of which were performed following inconclusive mammograms … read more »

A study published in the Dec. 8 online editon of Circulation: Cardiovascular Imaging, a journal of the American Heart Association, shows surprising differences in the way the heart beats between men and women of different age groups. Using a precise new technique called MRI phase mapping, scientists in Germany studied 29 men and 29 women, all healthy and ranging in … read more »

On Monday federal health officials gave recommendations to help lessen radiation risks during CT brain perfusion scans, often done on stroke patients. The interim guidelines come as part of an ongoing investigation that began in October, when the FDA discovered more than 200 cases of overexposure—up to eight times the normal amount of radiation—at Cedars-Sinai Medical Center in Los Angeles. … read more »
