Yes, an MRI (magnetic resonance imaging) can be done without contrast, using only the magnetic field and radio waves to create images of the inside of the body. Contrast agents may be used to enhance certain structures or abnormalities in the images, but they are not always necessary for an MRI scan.

Magnetic Resonance Angiogram It is used, typically with a slightly radioactive contrast agent injected into the arm, to visualize blood vessels, often in the brain. Actually the contrast agent isn't radioactive at all (you're thinking of nuclear medicine procedures). It's paramagnetic and can be used to visualise any blood vessel. There are ways of imaging blood vessels without any contrast agent at all, useful if the patient has any problems with their kidney function.
