This is especially true if you have known kidney disease or have undergone multiple MRIs with contrast. In rare instances, severe complications, such as infection, may occur (,14). 264, No. Ideally, the patient should be imaged within the 30 minutes following contrast injection; therefore coordination in the scheduling of fluoroscopy and MRI or CT is important. 25, No. Most individuals don’t feel anything after they receive a contrast injection. What the FDA advisement failed to say is whether the deposits pose any health risks. Patients younger than 30 years had more pronounced pain than did patients in other age groups at all time points (P = .044). If you have claustrophobia, let the staff know well in advance. ACR Manual on Contrast Media (Volume 10.3). However, other comments were not associated with the injected joint: these included headache, tiredness, vertigo, increased blood sugar level, and pruritus. Side Effects. After filling out the necessary paperwork and signing a consent form, you will be led to a changing room to change into a hospital gown (if needed). MR images were acquired with a 1.5-T MR imager (Symphony, Avanto, or Espree; Siemens Medical Solutions, Erlangen, Germany) and with use of a four-channel shoulder array coil, a small circular polarized extremity array coil for the elbow, a four-channel coil for the wrist, a four-element body matrix coil used in combination with a four-element spine matrix coil for the hip, an eight-channel transmit-receive coil for the knee, and a transmit-receive extremity coil for the ankle. Pain scores were assessed at all time points. The synovial membrane was not evaluated in this investigation. 2019;20(1):134-47. doi:10.3348/kjr.2018.0356, Gulani V, Calamante F, Shellock FG, Kanal E, Reeder SB. More serious side effects may occur as a reaction to any contrast medium used for the MRI. 4, 19 March 2012 | Clinical Anatomy, Vol. Arthrography is an MRI technique used to image joints if a standard MRI does not provide enough detail. Arthrography requires an intra-articular injection of GBCA into the joint space. and three junior [N.S.] 4, No. Author contributions: Guarantors of integrity of entire study, N.S., J.H. Mild pain is most pronounced 4 hours after MR arthrography and disappears within 1 week after MR arthrography. There may be reasons why contrast is needed, but it's fair to ask if there are other options. There is no significant relationship between pain score and radiologist experience. Side effects were encountered with 3.6% of arthrograms in a survey that included 262 000 arthrograms, 13 000 of which were MR arthrograms. A total of 76 (7.0%) patients spontaneously provided free comments. Predictor variables included time after injection, injected joint, volume of gadolinium-containing contrast agent injected (categories were relative difference of given volume and values indicated in the standard operating procedures of our institution [less than −30%, −30% to −10%, −9% to 9%, 10% to 30%, and more than 30%]), type of contrast medium administered (gadopentetate dimeglumine or gadoterate), age groups (group I, <30 years; group II, 30–45 years; group III, 46–65 years; group IV, >65 years), patient sex, physician experience (senior staff radiologist, junior staff radiologist, resident), and use of analgesics before the procedure, along with two-way interactions of each parameter with time point. The variables were evaluated one by one to achieve convergence and a nonsingular Hessian matrix. The phone interview conducted 1 week after injection was intended to enable us to assess procedure side effects, including infection. MR arthrography is more accurate than standard MR imaging in the detection of many internal derangements (,1–,5,,7–,10). All patients gave written informed consent. A randomized controlled trial, Magnetic resonance arthrography of the hip: technique and spectrum of findings in younger patients, CT Arthrography, MR Arthrography, PET, and Scintigraphy in Osteoarthritis, Ultrasound-guided Gadolinium Joint Injections for Magnetic Resonance Arthrography: A Step-by-Step Approach, Oh, Places Contrast Will Go! All patients were asked to comment freely during phone interviews. In addition, we acquired pain score data in only the patients who were eager to cooperate, and this may have resulted in a selection bias. The contrast will be given through a small needle placed into a vein. VAS = visual analogue scale. This helps to show up parts of the body not always clearly seen, like blood vessels, the kidneys and liver. Magnetic resonance imaging (MRI) gadolinium. Read our, Medically reviewed by Stuart Hershman, MD, Medically reviewed by Diana Apetauerova, MD, Medically reviewed by Douglas A. Nelson, MD, Medically reviewed by Matthew Wosnitzer, MD, Medically reviewed by Yasmine S. Ali, MD, MSCI. Note.—Unless otherwise indicated, data are mean volumes of injected fluid (measured in milliliters) ± standard deviation. The iodinated contrast agent used for this purpose, in combination with preexisting joint fluid and local anesthetics, may reduce the gadolinium concentration to a nondiagnostic level (,18). 11, Magnetic Resonance Imaging Clinics of North America, Vol. If you plan to wear any small jewelry there, you may want to bring a pouch for safekeeping. As the guidelines illustrate, the choice to use or not use a GBCA is largely subjective and relies on a doctor's judgment and experience. If a sedative was not used, you can usually dress and leave immediately. These noises are the result of liquid in the joints. 3, Revue du Rhumatisme Monographies, Vol. Some people come with their own clothes, such as drawstring pants, sweatpants, plain T-shirts, or workout wear. Jonathan Cluett, MD, is a board-certified orthopedic surgeon with subspecialty training in sports medicine and arthroscopic surgery. A contrast (dye) injection can give more information from the scan. Nonparallel time courses for pain scores were found for other factors as well. Joint type, contrast agent volume (P = .44), patient sex (P = .29), and radiologist experience (P = .10) did not significantly affect pain scores. This serves to highlight any and all organs that have vascular flow.
