But that is his experience! Once you learn how to replace a smoke alarm, a carbon monoxide detector should be next. My recommendation: buy a good plug-in detector! If you want, get one with a battery back up. Put it near any potential CO source and another near your bedroom(s). And you will be safe and feel safe.
The most commonly used MRI contrast agent is the element gadolinium. As with radiographic agents, gadolinium can be injected into the blood vessels or injected into a joint. Gadolinium-enhanced MRI scans can be very helpful at showing subtle findings such as labral tears in the shoulder and hip cartilage damage.
One of the feeding tubes (Mclean-Ring Enteral Feening Tube) used at UCSF is not safe for MRI. The commonly used Corflo feeding tube (the yellow tube, including those with tungsten-weighted tips) is MRI safe at 1.5T and 3T with the stylet removed.
