![]() Google is free whereas a medical education is many long years and hundreds of thousands of dollars. Many of our patients spend hours researching the results of their Cervical Spine MRIs. The internet has made medical information widely available. ![]() A Deeper Look into A Normal vs Abnormal Cervical Spine MRI What is a Cervical MRI? How does an MRI work? Does MRI imaging use x-ray? What are the differenes between a normal vs abnormal Cervical Spine MRI? What are the advantages of MRI based diagnoses? What are the shortcomings of traditional MRI imaging? When should you get a Cervial Spine MRI? What does a normal Cervical Spine MRI look like? What are the most common abnormal findings? What are the consequences of misinterpreting a Cervical Spine MRI? What alternative exists? Lets dig in. Your doctor ordered a Cervical MRI and you are awaiting the results. At times there were sharp, shooting pains radiating down your arm with accompanying numbness and tingling. Simple tasks and motions were impossible. doi:10.The neck pain was unrelenting and unresponsive to conservative care.

When confluent may appear as joint space wideningīackfill: intra-articular high T1 signal filling up excavated bone erosionsįat metaplasia: periarticular fat deposition More prominent anteroinferiorly and on the iliac side of the SIJ Subchondral sclerosis: bands of low signal (on all sequences) paralleling the joint margins, at least 5 mm from the joint spaceĮrosions: marginal foci of articular bone loss ![]() Synovitis and capsulitis: thickening and contrast enhancement of the synovium and joint capsuleĮnthesitis: thickening and contrast enhancement of ligaments and tendons at their attachments to bone Marrow edema (first to appear): high signal on water sensitive sequences MRI features of sacroiliitis can be divided into inflammatory and structural lesions 6,7: Though not routinely used for evaluating the sacroiliac joints, MRI is capable of identifying early inflammatory changes of joints when other imaging is negative and excludes other differential causes such as disc prolapse which may resemble clinical symptoms of sacroiliitis. It is also valuable in excluding stress fractures and other bone pathologies. Nuclear medicineīone scans demonstrate increased radioisotope activity of the joints and helpful in localizing the source of the pain. However, due to higher radiation exposure, it is not advisable to use CT for diagnosis or follow-up purposes. Sclerosis of the endplates particularly on the iliac sideĬT examinations offer greater sensitivity, accuracy and detailed information compared to plain radiography. Specific sacroiliac joint views are helpful in the evaluation and comparing both sides of sacroiliac joints. See article: sacroiliitis (differential) ClassificationsĪSAS sacroiliitis classification system (MRI)Ĭonventional radiography remains the first line of imaging despite its poor sensitivity and specificity in early disease. The causes of sacroiliitis can be divided into unilateral or bilateral. Up to 50% may have pain radiating to the lower extremity. People with sacroiliitis commonly present with ipsilateral or bilateral buttock and/or midline lower lumbar area pain.
