  Sometimes a chemical contrast medium is injected into the body to enhance and improve the quality of the image. Gadolinium contrast media is used as a dye or contrast agents. The main difference between MRI with contrast and MRI without contrast is that, when a contrast is injected it is done with the intention of highlighting certain parts of soft tissue. Whereas an MRI without Contrast is cleaner than the other. Most MRI Scans are done without the contrast medium. Contrast material, Gadolinium is generally very safe.

  MRI scans are painless and thought to be safe. MRI scans do not use X-rays so the possible concerns associated with X-ray pictures and   CT scans   (which use X-rays) are not associated with MRI scans. However: Rarely, some people have reactions to the contrast dye which is sometimes used. Pregnant women are usually advised not to have an MRI scan unless it is urgent. Although the scan is thought to be safe, the long-term effects of strong magnetic fields on a developing baby are not yet known. What can I expect after the scan? There are no after effects from the scan. You can return to your normal activities as soon as the scan is over. The scan pictures are studied by a specialist who interprets them - a radiologist - who sends a report to the doctor who requested the scan. It is usual to have to wait for at least two weeks before hearing about your results. If there are any urgent findings, the specialist will be informed as soon as possible. see here
