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.
How to Prepare for Your MRI and MRA Contrast Study. If you are having an MRI or MRA with a contrast injection please be sure drink plenty of water before and after the exam. This will ensure that the injection itself is as painless as possible and that the Gadolinium is flushed out of your system quickly. Not all patients can receive Gadolinium injections.
