Your doctor can discuss the benefits and risks in your specific case. In most situations, the benefit of an accurate diagnosis far outweighs the small risks of contrast.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNow you can spot the pattern:\u003c\/strong\u003e In general, structural problems (discs, joints, fractures, routine headaches) rarely need contrast, while inflammatory, infectious, and neoplastic (tumor) problems usually benefit from it. The more the suspected problem involves abnormal blood vessel activity, the more likely the protocol will include contrast.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBring your imaging to your doctor.\u003c\/strong\u003e After your MRI, you will typically receive a copy of the images on a CD or digital access. Bring this to your follow-up appointment. Many practices also use image-sharing networks that automatically transmit the images to your referring physician.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003eThe reference sheet also highlights the importance of proper scan selection for \u003cstrong\u003efollow-up examinations\u003c\/strong\u003e. If you are being monitored for a known condition — such as a brain lesion, a liver mass, or an aneurysm — the protocol described here ensures that your new scan can be directly compared with your previous one. Changes in lesion size, enhancement characteristics, or blood vessel dimensions can then be detected with confidence.\u003c\/p\u003e\n\n\u003cp\u003eFinally, be prepared for \u003cstrong\u003epre-certification\u003c\/strong\u003e. Your doctor's office will often need to obtain insurance approval before your scan, and the CPT codes in this document are part of that process. If your insurance denies a scan, it may be because the protocol does not match the listed reason for the exam. Bringing these guidelines to your doctor's attention can help resolve such issues.\u003c\/p\u003e\n\n\u003c!-- ddn:faq:start --\u003e\n\u003ch2 id=\"ddn-faq\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is MRI contrast and why is it used?\u003c\/h3\u003e\n\u003cp\u003eMRI contrast is a substance containing gadolinium, injected into a vein. It circulates in your bloodstream and briefly collects in areas with more blood vessels or where the blood-brain barrier is damaged. On images, these areas appear brighter, helping radiologists tell normal tissue from infection, inflammation, tumors, or abnormal blood flow.\u003c\/p\u003e\n\u003ch3\u003eWhy does my MRI order say 'without and with contrast'?\u003c\/h3\u003e\n\u003cp\u003eThis means you receive two sets of images: one before the injection and one after. Comparing them reveals which areas 'light up' with contrast. This helps characterize masses, infections, inflammatory conditions, or active MS plaques. Your doctor needs this comparison to make an accurate diagnosis or guide treatment decisions.\u003c\/p\u003e\n\u003ch3\u003eWill I need contrast for a brain MRI for headaches or memory loss?\u003c\/h3\u003e\n\u003cp\u003eUsually no. For conditions like headaches, migraines, memory loss, seizures, stroke, or trauma, a brain MRI without contrast is standard. These problems cause structural changes visible without injection. Contrast is added when there is concern for a mass, infection, multiple sclerosis, or other conditions that affect the blood-brain barrier.\u003c\/p\u003e\n\u003ch3\u003eIs MRI contrast safe? What risks should I know about?\u003c\/h3\u003e\n\u003cp\u003eGadolinium contrast is generally safe, but it carries a small risk of allergic reaction. In patients with severe kidney disease, there is a rare but serious risk of nephrogenic systemic fibrosis (NSF). Tell your radiology team about any allergies, kidney disease, diabetes, or pregnancy before your scan.\u003c\/p\u003e\n\u003ch3\u003eWhat is an arthrogram and how is it different from a regular MRI?\u003c\/h3\u003e\n\u003cp\u003eAn arthrogram is a specialized MRI where contrast is injected directly into the joint space, not into a vein. It is used when a routine MRI may miss a tear, such as a labral tear in the shoulder or hip. The injection site may be sore temporarily, and the scan typically takes longer.\u003c\/p\u003e\n\u003ch3\u003eWhy doesn't my back pain MRI need contrast?\u003c\/h3\u003e\n\u003cp\u003eMost back pain is caused by degenerative changes, disc herniation, or spinal stenosis—structural problems clearly visible without contrast. The natural cushion of discs and fat around nerve roots provide enough contrast on their own. Contrast is added when infection or a mass is suspected, such as discitis or osteomyelitis.\u003c\/p\u003e\n\u003ch3\u003eWhat should I do before my MRI to prepare?\u003c\/h3\u003e\n\u003cp\u003eCheck that the reason on your MRI order matches your symptoms. Inform the radiology team about allergies, kidney disease, diabetes, pregnancy, implanted devices, and any prior surgery—especially back surgery within 10 years. Ask your doctor why this particular protocol was chosen. Even if your order says 'without contrast,' the radiologist may decide contrast is needed during the scan.\u003c\/p\u003e\n\u003ch3\u003eWhen should I get a second opinion on whether my MRI should be done with or without contrast?\u003c\/h3\u003e\n\u003cp\u003eMRI contrast is not always necessary. Structural problems such as a herniated disc, routine joint pain, or uncomplicated headache are usually evaluated without contrast. If infection, tumor, multiple sclerosis, or spinal infection is suspected, a without-and-with contrast study is typically needed. Because individual history, prior imaging, allergies, and kidney function can change the appropriate protocol, a second opinion can confirm whether the ordered scan matches your specific situation. Bring your MRI order, images and report, allergy list, kidney function results, and surgery history.
