MRIs take a long time to complete because they take many hundreds of images of your tissue in slices. They then build this up into a three-dimensional representation that doctors can study.
MRI scans usually take between 45 and 60 minutes, but can sometimes take up to 2 hours. After the test, you may be asked to wait while the pictures are checked to make sure that they are clear and show all of the body part. If not, more pictures may be needed.
The Radiologist will send a report to the doctor who arranged the scan. They'll discuss the results with you. It usually takes 1 to 2 weeks for the results of an MRI scan to come through, unless they're needed urgently.
A magnetic resonance imaging (MRI) scan is a painless procedure that lasts 15 to 90 minutes, depending on the size of the area being scanned and the number of images being taken.
Speed: CT scans take much less time than MRIs. The exact time required depends on whether you need a contrast dye for the procedure, but MRIs always require more time for the scan. A typical CT scan lasts 10 minutes whereas MRIs can take up to an hour or longer.
Imaging is used not only for local staging but also to differentiate between benign and malignant lesions. MRI is the preferred imaging modality for the evaluation of soft-tissue masses in clinical practice.
“They aren't doctors, and while they do know how to get around your anatomy, they aren't qualified to diagnose you.” That is true even though the tech likely knows the answer to your question. Imaging techs administer thousands of scans a year.
The radiologist may discuss initial results of the MRI with you right after the test. Complete results are usually ready for your doctor in 1 to 2 days.
The results from an MRI scan are typically interpreted within 24 hours, and the scans themselves are usually given immediately to the patient on a disc after the MRI is complete.
The radiologist may tell you some of the results of the MRI right after the test. Full results are sent to your doctor or specialist in 1 to 2 days.
You won't have pain from the magnetic field or radio waves used for the MRI test. But you may be tired or sore from lying in one position for a long time. If a contrast material is used, you may feel some coolness when it is put into your IV.

If medically urgent, or you have an appointment immediately after the scan to be seen by your doctor or health care provider, Melbourne Radiology Clinic will have your results ready without delay. Otherwise, the report will be received by your doctor or health care provider within the next 24 hours.
What medications are used? Propofol will be given through an I.V. to induce sleep. This medication has a short duration of action and a rapid recovery time and is administered to make sure you remain asleep during the entire MRI study.
Keep your eyes closed or even wear a blindfold.
It's much easier in an open MRI it's wider than a standard scanner, so patients shouldn't feel any walls touching them.
Calcifications within a tumor are white on CT (Figure 3) and usually a signal void (black) on MRI. These may represent residual normal bone or tumor matrix. Calcified tumor matrix suggests a bone- or cartilage-forming tumor, such as a chondrosarcoma.
The scan typically takes about 30 to 60 minutes. According to Cincinnati Children's Hospital and Medical Center, scans that don't require a contrast dye are generally shorter and may only take 30 to 45 minutes. Some procedures like the limited brain MRI only take about 5 minutes.
If you have a concern that your MRI revealed something that needs to be treated urgently, you can call your doctor's office. However, if a radiologist identifies emergency findings, they will usually contact you. This is especially true if you require immediate treatment.
Since the MRI machines are magnets, it is best to not apply deodorants, antiperspirants, perfumes, or body lotions before the examination. These items contain metals that might interfere with the magnetic field inside the MRI machine and cause you to have distorted images and wrong results.
If You Have an Overactive Bladder
This feeling of urgency can make it harder to hold urine in. While you may still experience this urgency to a degree, not drinking for several hours before your procedure can make you less likely to experience incontinence during the scan.
The radiologist writes the report for your provider who ordered the exam. Typically, the radiologist sends the report to the person who ordered your test, who then delivers the results to you. Many patients can now access their electronic health records online.
The average cost of an MRI can range anywhere from $400 to $12,000, depending on the place of service, health insurance, location, extra medications, the provider, and body part scanned. Health insurance typically covers authorized MRIs.
Body MRI scans are used to help diagnose or monitor treatment for a variety of conditions within the chest, abdomen, and pelvis. But recent research found that nearly 70% of all body MRI interpretations have at least one discrepancy.
Ultrasound can usually help differentiate between benign and malignant tumours based on shape, location, and a number of other sonographic characteristics. If the ultrasound is inconclusive, your doctor may request follow-up ultrasound to monitor the tumor or a radiologist may recommend a biopsy.
MRI exams—as well as all radiology exams—can be misinterpreted by the radiologist for a variety of reasons. A false negative diagnosis can lead the referring doctor and their patient down the incorrect path and delay critical treatment.
