What To Do Before Mri Scan
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
Safe procedure: Mri is one of the safest medical procedures. Risks result from incompatibility of some medical devices such as pacemakers. You will be screened to make sure you do not have a device or condition that would place you at risk. Other potential risks result from mild heating (similar to that from exercise), noise, and claustrophobia. Most patients have no problems with the procedure. ...Read more
Claustrophobia: Many people who have never had an MRI study before are concerned about experiencing claustrophobia during the scan. There are multiple methods to deal with this issue including meditation during the scan, having the MRI on an "open" machine to reduce the sensation of claustrophobia, or having the doctor that requested to study also prescribe a medication such as Xanax (alprazolam) to help you relax. ...Read more
Very different: Pet is a technique for measuring concentrations of positron-emitting radiopharmaceuticals and presenting these as a metabolic image of the body. F18-fdg, a "radioactive sugar", is the most commonly used radiopharmaceutical in oncology. Mri uses a combination of a strong magnetic field and radio waves to produce anatomic images of the body without the use of radiation. ...Read more
MRI report: What does the report say? You can ask your doctor for clarification, or post a specific question about the report. ...Read more
Not usually: Most MRI studies are done without contrast. The studies done with contrast usually include an injection part way through the study. Occasionally, if a person is claustrophobic, the Doctor may give you a shot before the study to help you relax. Discuss details with your Doctor, or the staff of the MRI center before you go there. ...Read more
Not: Enough information here to answer the question. Try to be more specific. ...Read more
Depends: It depends on your symptoms and the area of the body that is being scanned. There are other imaging modalities available, including CT, nuclear medicine and Ultrasound, as well as routine x-rays. Some patients cannot have an MRI study due to claustrophobia or contraindications to MRI, and these patients can be scanned with these other modalities. Discuss alternative imaging with your Doctor. ...Read more
Varies: Every testing facility has a different turn around time. The results then get sent to your doctor, and each office has a unique turn around time as well. ...Read more
Not much.: Just try and relax and bring any information regarding and implanted "thing" (if you have any) in your body. You don't usually need to fast or anything like that. However, if you are having a breast MRI it needs to be scheduled around certain parameters of your menstrual cycle. ...Read more
Don't worry: Many people get scared about the mri. But there's nothing to worry about. It's not an x-ray so there's no radiation. However, it takes longer to scan, it's noisy, and the tube is smaller. So the main problem is claustrophobia. If you have that or suspect you may feel that, let your doctor or the radiologist know beforehand and they can give you a low dose sedative to help you relax. ...Read more
