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.

Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures that are inside the body. During the MRI test (also called an MRI scan), you usually lie on your back on a table that is part of the MRI scanner.
