![]() ![]() Once you’re comfortable on the table, your technologist will slide the table into the scanner and begin your MRI. It makes a loud tapping noise during the scan. The MRI scanner is a large, donut-shaped magnet. Your technologist will bring you to the scanning room and help you onto the MRI table. At this time, you should tell your doctor about any speech difficulties you may have. You may be asked to think of words that fit a category or answer questions about your speech or strength. Your doctor will talk with you about the fMRI tasks that you’ll be doing before you go into the MRI scanning room. This is because objects with even a small amount of metal can fly into the magnet, and the magnet can damage mobile phones and credit cards. For safety reasons, you will place your clothing, credit cards, and any objects (such as your phone, jewelry, coins, and glasses) in a locker. You will change into a hospital gown before going into the scanning area. Don’t take it without speaking to the technician performing the fMRI first. If your doctor prescribed medication to help you relax during your fMRI, bring it with you.If you wear a medication patch on your skin, bring an extra one with you.You may take your medication(s) as usual before your fMRI.If you have a medical device, bring the information card that your nurse gave you to your fMRI.Check the printed reminder you received from your doctor’s office for the time and location of your fMRI.If you’re not sure how to manage your glucose while your device is off, talk with the healthcare provider who manages your diabetes care before your appointment.īack to top The Day of Your fMRI Things to remember Make sure you have an extra device with you to put on after your scan or procedure. Talk with your healthcare provider about scheduling your appointment closer to the date you need to change your device. If you wear any of the following devices on your skin, the manufacturer recommends you remove it before your scan or procedure: Make sure you have an extra medication patch with you to apply after your fMRI. This is because metal in the patch may heat up during your fMRI and cause burns. If you wear a medication patch on your skin, you may need to remove it before your fMRI.This will make it easier to complete the tasks presented to you while you are in the fMRI. If you wear contact lenses, please wear them the day of the fMRI.If you think you’ll be uncomfortable lying still or if you’re afraid of being in a narrow or small space, talk with your doctor or nurse ahead of time. During your fMRI, you will lie on your back with your arms at your side.If you don’t have this information before your fMRI, you may not be able to have the fMRI that day. If you have a medical implant or device (such as a stent or port), ask the doctor who put it in for the exact name and manufacturer.The activation pattern with analgesic agents seems to be specific to the class of drugs.Īs we learn more about fMRI related to pain, functional connectivity patterns could emerge as biomarkers for specific pain conditions.Back to top Before Your fMRI Getting ready Techniques for fMRI analysis, templates, and standards for identifying the functional networks in the brain are evolving continuously. In addition, the DMN encompasses the PFC. Default mode network (DMN) to insula connectivity is associated with spontaneous pain in fibromyalgia patients. The dorsal medial PFC to insula connectivity can identify patients prone to persistent back pain. Functional connectivity between the prefrontal cortex (PFC), ACC, and insula correlates well with clinical pain measures. The primary and secondary somatosensory cortex (S1 and S2), anterior cingulate cortex (ACC), and insula are the four regions (part of pain matrix) consistently activated in pain states. Although the conventional fMRI technique has been the isolation of regions in the brain transmitting and modulating pain, functional connectivity measurement can identify functionally linked regions associated with pain processing. With fMRI, the subjective effects of pain (sensory, affect, emotion, and motor components) can be objectively imaged. This article reviews the current state of knowledge in functional MRI (fMRI) research related to pain with primary focus on clinical studies.
