MRI Safety: Monitoring Body Temperature During MRI

August 04, 2011

This monograph focuses on the need to monitor body temperature in patients during MRI and discusses the sites to record temperature based on efficacy and stability of the measurement, as well as the response time (i.e., the temporal resolution) during temperature fluctuations.

MRI Safety: New Cardiac Pacemaker System Now Available in the U.S.

April 14, 2011

On February 8, 2011, a new cardiac pacemaker received approval from the FDA, which for the first time allows MRI procedures to be performed in patients by following specific labeling requirements. The “MR Conditional” Revo MRI SureScan Pacing System from Minneapolis-based Medtronic Inc. was designed to minimize the potential interactions with the electromagnetic fields used during MRI examinations.

MRI safety: Patients with insulin pumps require special cautions

October 05, 2010

An insulin pump allows the replacement of slow-acting insulin for basal needs with a continuous infusion of rapid-acting insulin. By using an insulin pump, a patient can typically match the dosage of insulin to lifestyle and activities, rather than adjusting those to the body’s response to insulin injections. The advantages of using an insulin pump include the fact that an insulin pump replaces the need for periodic injections by delivering rapid-acting insulin continuously throughout the day via a catheter. It greatly simplifies the management of diabetes.
