For certain conditions, an additional MRI sequence using contrast can help more accurately determine the anatomy and pathology of the area of the spine being studied. These contrast agents make the abnormality in the tissues brighter and clearer—helping doctors identify the pathology with greater prec...
Most MRIs are performed without a contrast dye because it isn't needed to get accurate results for the suspected problem. Also, certain patients (those who are pregnant as well as those withkidney disease) shouldn't get the contrast dye because of possible complications. What Is an MRI Scan ...

evaluation of a patient with signs or symptoms of spinal stenosis, where MRI or CT are equally appropriate. For evaluation of recurrent symptoms after spinal surgery, MRI with and without gadolinium enhancement, is the preferred method of imaging. Magnetic resonance imaging or CT evaluation of chron...
Magnetic resonance imaging, with or without gadolinium contrast, was identified using OHIP billing codes, which are assigned for every inpatient or outpatient MRI performed in the province (eTable 1 in the Supplement). For first-trimester MRI (cohort 1), 5 study outcomes diagnosed before age 4 ...

An MRA test is similar to an MRI. As such, during the MRA, you’ll need to lie as still as possible so the technologist can obtain the best quality images for the radiologist. MRA scans can be performed with a contrast material or without. If required, the technologist administers the ...
HTML Purpose: To examine the contribution of intravenous gadolinium contrast material administration in the MRI work-up of suspected spine abnormalities in children under two years of age. Methods and Materials: During a 7.5-year period (1995-2002) 405 MRI examinations of the spine have been perfo...
