MRI Advances

MRI_cardio_scan_blog_july09.JPG There is now hope that those with non-pacemaker-dependent implantable cardioverter defibrillators (ICD) may be able to use an MRI scan. Up until now, patients with cardioverter defibrillators were warned against MRI scans due to the high level of magnetism. Now, a new study shows that these ICDs may be able to withstand an MRI without disruption of the heart rhythm or rate. "The number of implanted pacemakers and ICDs, as well as the number of devices for cardiac resynchronization therapy, are going up every year. People are getting older, and the older they get, the greater the likelihood they're going to need an MRI exam" states the study leader to Heartwire. The study still warns ICD users that extra precaution must be taken to monitor the heart during the exam. MRI exams should only be used on patients were the benefits outweigh the potential risks. Technology is growing at a fast pace to keep up with the growing demand for such tests. The baby-boomer generation is getting older, and with that comes a large demand for efficient tests that are compatible with heart monitoring implants.
