How long do MRI results take in the UK? What to expect after your scan

The NHS states that it usually takes between 1 and 2 weeks to receive MRI scan results. That is the time between having the scan and the result reaching the doctor who referred you, who then passes the findings on. It is a typical figure rather than a guarantee. Some scans are reported more quickly, particularly when a doctor needs an answer to make a decision about treatment, and some wait longer when a department is busy or the images are complex.

It helps to separate two things that people often run together: how long the scan takes to report, and how long it takes for you to be told. A radiology report may exist several days before you hear from anyone, because it first goes to the clinician who requested it. They then need to review it, decide what it means for you, and arrange to speak to you or write to you.

An MRI scan is carried out by a radiographer, who runs the scanner from a control room and checks that the pictures are good enough to use. The images are then stored digitally. According to NHS inform, the scan needs to be studied by a radiologist, a doctor trained in interpreting scans and X-rays.

The radiologist looks through the image sets carefully, often comparing them with earlier scans if you have had any. They then dictate or type a report. The NHS says the radiologist will write to the doctor who referred you. That report describes what was seen and may include a conclusion and, sometimes, a recommendation such as a further test.

Some scans are also discussed at a multidisciplinary team meeting, where specialists from different disciplines review the images together. This is common when the result affects decisions about surgery or cancer treatment, and it can add a short extra step before you are told.

You will usually hear from the person who asked for the scan. For a GP referral, that is normally your GP surgery. For a scan arranged by a hospital consultant, it is usually the consultant or their team, often at a follow-up clinic appointment. The NHS notes that you may need a follow-up appointment to talk about your MRI scan results.

Practices differ in how they communicate. Some phone, some send a letter or message, and some ask you to book an appointment. If you were told at the time of the scan how and when you would hear, that is the best guide. If nobody explained, it is reasonable to ask the surgery or clinic when you arrange the scan or on the day.

The NHS says the doctor should talk to you about your results and explain what happens next, and that you should tell them if you have questions or do not understand your results. A result that says something looks normal still deserves a short explanation, because it may not account for the symptom that led to the scan.

Silence is common and is usually administrative rather than a sign of bad news. The NHS says that if you have not heard anything after a few weeks, you should contact the doctor who referred you for the scan. Ringing the hospital radiology department is rarely helpful, because radiographers and reception staff there generally cannot give results or interpret reports.

When you get in touch, it helps to give the date and place of the scan, the body part that was scanned and the name of the doctor who requested it. Ask whether the report has been received and when you can expect to discuss it.

• Have the date, hospital and type of scan to hand.

• Contact the referring GP surgery or the consultant secretary rather than the scanner reception.

• Ask whether the report has arrived and how you will be told.

• Write down what you are told, including any follow-up date.

Several things can stretch the wait. The scan may need to be compared against older images that are held at another hospital. A complicated study, such as a whole-spine or heart scan, takes more time to report. The report may be queued behind more urgent scans, which are reported first. A report may also need to be checked or discussed in a team meeting before it is released, or the referring clinician may simply be on leave and the report may sit until they return.

None of these delays alters the quality of the report. If you are worried that the wait is affecting your care, you can say so, and your GP or the hospital team can check whether the report is available and whether anything is outstanding.

Waiting for a result is not a reason to ignore new or worsening symptoms. If you develop new symptoms, or your symptoms change quickly, contact your GP or NHS 111 for advice. For severe or sudden symptoms such as a sudden severe headache, weakness on one side, difficulty speaking, loss of vision, chest pain or difficulty breathing, call 999 or go to A&E. A pending MRI result does not change that advice.

If you were told your scan was urgent, for example because cancer is suspected, say so when you ask about timing, so that the right team can check where the report is up to.

On the NHS the wait has two parts: the wait to have the scan, which varies by area and urgency, and the 1 to 2 weeks the NHS gives as a usual reporting time. Scans for urgent concerns are generally prioritised.

Some people choose to have an MRI privately, mainly to shorten the wait for the appointment itself or to get a quicker report. The images are still read by a radiologist and the report still has to be interpreted by a doctor who knows your history. A report on its own, without that explanation, can be confusing, so it is sensible to know who will go through it with you and what happens if it shows something unexpected. Private reports can also be shared with your NHS doctor, which avoids repeating the scan.
