Medtronic receives CE mark for its Pacing System

Medtronic Inc. has received CE (Conformité Européenne) Mark for the first-ever MR-Conditional pacemaker system, the EnRhythm MRI TM SureScan TM pacemaker and CapSureFix MRI TM SureScan TM pacing leads (Model 5086MRI). The new system was designed, tested and approved for use with magnetic resonance imaging (MRI) under specified scanning conditions, and is now commercially available in select European countries. Patients receiving the EnRhythm MRI SureScan Pacing System will for the first time be able to undergo MRI scans under certain conditions, representing a major milestone in the evolution of implantable cardiac devices.

Advanced MRI diagnoses traumatic brain injury

Doctors from Weill Cornell Medical College and University of California have found evidence which links memory loss to brain damage following mild traumatic brain injury. This recent discovery can prove helpful in diagnosing when a routine concussion can cause lasting cognitive problems. Patients who experience concussion following a head injury show no signs of damage in a traditional MRI scan or CT. On passing the basic neurological test, they are sent back home without a treatment. Researchers examined diffusion tensor imaging (DTI). This advanced form of MRI facilitates the study of microscopic movement of water molecules within the white matter of brain.

Ultrasound or MRI preferable in diagnosis of IBD

According to US researchers who conducted meta-analysis of 33 prospective studies, ultrasound or MRI should be the imaging modality of choice in inflammatory bowel disease (IBD). While colonoscopy and barium examination can also be used, these methods are time consuming. Moreover, colonoscopy is invasive and may result in perforation in severe ulcerative colitis. Reported sensitivities and specificities of other options, such as ultrasonography, CT, MRI and scintigraphy, vary and, hence, are not extremely reliable.
