MRI Basics

An MRI can examine internal bone and tissue in three dimensions. It is a non-invasive procedure that doesn't use the radiation generated by x-rays.

Indications

An MRI of the lumbar spine is a scan of the lower third of the spinal column. It can detect any kind of spine malformation, disc compression, certain kinds of tumors, postoperative scarring, inflammations, and infections.

Contrast

For a better view, MRIs can be performed with contrasting agents. These enhanced MRIs can help the physician better determine the nature of infections and tumors. The doctor can better measure the effects of spinal surgery with contrast, examine the condition of connecting tissue and blood vessels, or simply have a more detailed look at a previous MRI done without the contrast.

Gadolinium

Gadolinium is a rare-earth element that is used in the manufacture of some contrast agents in MRI scans. Before the scan, the gadolinium-based agent is administered by injections.

Side Effects

There have been some side effects reported with the use of gadolinium-based contrast agents in MRIs. These include allergic skin and respiratory reactions, dizziness, blood clots, nausea, headaches, and shortness of breath. Gadolinium has also been linked to kidney disease in those already undergoing dialysis.
