![]() Your physician will let you know when you need to return for any follow-up visits. ![]() Usually nothing is required, although your doctor may recommend over-the-counter pain relief medication. Most patients will be able to go home later that day.īefore discharge, monitoring equipment will be removed and you will receive specific discharge instructions from your doctor. After these images, you will be moved to a recovery room. After TreatmentĪfter coming out of the MRI machine, we will remove the frame from your head before scanning a few more images to confirm the location of the treatment. The time depends on many factors associated with the shape and density of your skull. The procedure typically lasts a few hours. Once your physician is confident of the location, the focused ultrasound energy will be increased in the same location to make the improvement in tremor permanent. During Treatmentĭuring the sonication treatment, your physician will ask you questions and have you perform tasks like writing or tracing lines to confirm the tremor is improving. Cool water from your helmet will circulate around the top of your head to prevent heating from the ultrasound. You will be given a Stop button to hold during the procedure, so you can pause the treatment at any time. Small doses of ultrasound energy will be given to help confirm proper target in the brain. To plan the procedure, MRI images will be obtained so that your physician can locate the area to be treated. They will be able to monitor you through the window to the MRI suite as well as with a camera, and you will have a nurse in the MRI suite with you to monitor your vital signs and ensure you are doing well. You will be conscious throughout the procedure so you can communicate with the physicians and nurses, and your specialists will perform the procedure from a computer in the room next to the MRI suite. Next, you will lie on the bed that will move you in and out of the MRI device. Your heart rate, blood pressure, and blood oxygen levels will be monitored throughout the procedure. This will minimize potential heating near the scalp. ![]() ![]() A silicon membrane is then placed on the head to allow for circulation of cool water. You will be given numbing medication before a frame is placed on your head to prevent any movement during the procedure. Comfort measures will be taken as you receive medications for anxiety and pain, and staff will place a urinary catheter in your bladder so you won’t have to go to the bathroom during the procedure. This same nurse will be with you throughout the procedure. To start your treatment, you will meet the nurse who will be shaving and cleaning your scalp. Ultrasound energy is also non-ionizing, meaning that you are not exposed to potentially dangerous radiation during the procedure. This energy causes a small burn in the targeted tissue.īecause ultrasound can pass through skin, muscle, fat, and bone without incisions, it is an ideal treatment tool. Your specialist will deliver ultrasound energy focused on an extremely small target in the brain (the VIM of the thalamus). This allows it to precisely treat only the intended target. The scanner also measures, very precisely, the increased temperature in the brain caused by the ultrasound energy. The scanner allows the physician to precisely plan, guide, and target a small, specific area of your brain. This procedure can be done while the patient is awake.
