Your doctor may have special instructions for you in preparation for your test, such as the need for a special diet or for a laxative, enema, or vaginal douche, depending on the kind of test you are having done. If you have not received such instructions or if you do not understand them, check with your doctor in advance.
For your comfort and for the best test results, you may be instructed to urinate just before the procedure.
If you are on hemodialysis and treated with a gadolinium-containing contrast agent (GBCA), your doctor may perform hemodialysis immediately after you receive the contrast agent .
