Magnetic Resonance Imaging (MRI) methods have been used widely in the past decades as a safe, non-invasive and non-radioactive method of diagnosing CVDs. However, because of their limited sensitivity, even the most expensive MRI scanners cannot detect and visualize molecular and metabolic activity in the heart with sufficient sensitivity and specificity.

The University of Maryland physician-scientists has treated the first patient in the United States with MRI-guided focused ultrasound for neuropathic leg pain as part of a pilot clinical trial.
It took time, patience and a team effort to get Harrison Atkins to co-operate enough to lie still for an MRI scan of his head. But the 2-year-old has made history for Pacific Radiology staff in Palmerston North, relaxing so completely during the noisy, claustrophobic procedure that he went to sleep in the middle of it.
The emerging technology of sonogenetics, a technique where cells are controlled by sound offers the potential to one day replace pharmaceutical drugs or invasive surgical treatments for neurological conditions like epilepsy, Parkinson's disease or posttraumatic stress disorder.
Almost no hospitals in the California Veteran's Administration system adhere to national guidelines that recommend the use of a clinical decision rule and a D-dimer test before patients with pulmonary embolism are referred for CT pulmonary angiography, new research shows.
Detailed scans of concussed hockey players found that the protective fatty tissue surrounding brain cell fibers was loosened two weeks after the injury — even though the athletes felt fine and were deemed ready to return to the ice. A loosening of that insulation, called myelin, slows the transmission of electrical signals between neurons, and shows that passing a concussion test may not be a reliable indicator of whether the brain has truly healed.
Big South Fork Medical Center received a shot in the arm last week with the launch of a new, state-of-the-art CT scanner. The new scanner, which had been installed over a period of several days significantly upgrading the diagnosis capability of the hospital’s radiology department.
Purdue University researchers are developing a novel biomedical imaging system that combines optical and ultrasound technology to improve diagnosis of life-threatening diseases.
