Magnetic Resonance Imaging (MRI) News and Research

RSS

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance.

New noninvasive imaging technique may help detect heart transplant rejection in children

Cardiologists at Washington University School of Medicine in St. Louis have developed a noninvasive imaging technique that may help determine whether children who have had heart transplants are showing early signs of rejection. The technique could reduce the need for these patients to undergo invasive imaging tests every one to two years.

July issue of Neurosurgery provides update on Human Connectome Project

A research effort called the Human Connectome Project is seeking to explore, define, and map the functional connections of the human brain. An update on progress in and upcoming plans for the Human Connectome Project appears in the July issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

MRI scans determine whether chemotherapy is working long before tumors shrink

Studies on some 55 U.S. men and women with potentially deadly liver or pancreatic cancers show that specialized MRI scans can tell within a month whether highly toxic chemotherapy is working and killing tumor cells long before tumors actually shrink – or fail to shrink.

Significant increase in use of CT, MRI and PET imaging over the last two decades

Among six large integrated health care systems between 1996 and 2010 there was a substantial increase in the use of advanced diagnostic imaging, including approximately a tripling of the use of computed tomography and nearly a quadrupling of the use of magnetic resonance imaging, as well as a substantial increase in estimated radiation exposure, according to a study in the June 13 issue of JAMA.

New study on motor chunking

You pick up your cell phone and dial the new number of a friend. Ten numbers. One. Number. At. A. Time. Because you haven't actually typed the number before, your brain handles each button press separately, as a sequence of distinct movements.

Concussion victims have unique spatial patterns of brain abnormalities that change over time

Patients vary widely in their response to concussion, but scientists haven't understood why. Now, using a new technique for analyzing data from brain imaging studies, researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center have found that concussion victims have unique spatial patterns of brain abnormalities that change over time
