Electrical and forced-air warmers generally can't enter the scanner room, so that heat loss often goes unchecked. ConRad has no electrical or metal components, so it stays on the patient inside the scanner. How ConRad stops heat loss ConRad blocks three ways patients lose heat: Conductive: heat lost to the scanner table. Convective: heat carried away by air moving through the bore and suite. Radiant: heat radiated from the body into the cold room. Its thermal resistance tested equivalent to an extreme cold-weather polar suit. See Technical Details for the test results. Tested for MRI safety MRI safety: lab tested in 1.5 T and 3 T systems. Labeled MRI Safe. Image quality: no MRI signal loss and no RF interference. Clinical effectiveness: proven in clinical studies. Human medicine: also used for pediatric MRI at major academic medical centers.
