MRI Results: How Long They Take and What Happens Next

What happens after the images are taken

An MRI examination produces a series of images, often across multiple sequences and planes. The images are reviewed by a radiologist, who considers the structures shown, the reason for the scan and any relevant previous imaging. The report describes the findings and may explain whether they appear normal, suggest a possible cause of symptoms or need further investigation.

The time required to report a scan depends on the complexity of the examination, the number of images, whether comparison with previous studies is needed and the service's workflow. The date of the scan is not always the same as the date the report is discussed with the patient. Ask before booking how results are provided and who will help you understand them.

Why reports can use technical language

Radiology reports are written to communicate precise observations between healthcare professionals. Terms such as “mild”, “non-specific”, “degenerative”, “incidental” or “indeterminate” can sound worrying but do not have one universal meaning outside the context of the scan. The conclusion or impression section often summarises the key points, but the full report matters.

A report may describe changes that are common in people without symptoms. For example, some age-related changes in joints or spinal discs can appear on MRI even when they are not the cause of pain. This is why the report should be interpreted alongside the symptoms, examination and reason for imaging rather than read as a stand-alone diagnosis.

What contrast and scan complexity can change

Some MRI examinations use contrast, while many do not. Contrast may help assess selected abnormalities, inflammation, blood vessels or other structures, depending on the protocol. It does not automatically mean that the scan is more serious, and a non-contrast MRI can still provide very useful information for many clinical questions.

More complex examinations may involve more images or require comparison with previous studies, which can influence reporting workflow. With PrivateScans, results are returned within 3 days of the scan. Your images are reviewed by a GMC-registered consultant radiologist, and digital access to the report and images and a post-scan GP consultation are included in the scan price.

What to do if the report recommends follow-up

A recommendation for another scan, blood test, specialist appointment or comparison with previous imaging does not automatically mean a serious condition has been found. Sometimes the radiologist needs more information to characterise a finding or wants to check whether it has changed. The report should be discussed with the doctor looking after your care so the recommendation can be put into context.

Ask what the finding may mean, how urgent the next step is, who will arrange it and whether you should continue with any current treatment. If you had the scan privately but receive ongoing NHS care, share the report and images with your GP or specialist. Keep a copy of the report and any previous imaging information if you can.

Incidental findings and uncertainty

An incidental finding is something noticed on a scan that was not the main reason for the examination. Some are clearly benign and need no action; others may require comparison, follow-up imaging or a clinical review. A report may use cautious language when the images cannot provide a definite answer. That uncertainty is not itself a diagnosis.

Further testing can sometimes be recommended to rule out a problem, and this can understandably cause worry. Ask our doctor to explain the likely possibilities and the purpose of any next test. Avoid trying to diagnose yourself from isolated phrases in a report or from online image searches; the interpretation depends on the full images and your medical context.

When not to wait for a routine result

A planned scan and its report are not a substitute for urgent care. If you develop sudden weakness on one side, difficulty speaking, a first seizure, a sudden severe headache, severe chest pain, severe breathing difficulty or other emergency symptoms, seek emergency medical help. If your symptoms worsen substantially while waiting for results, contact a healthcare professional for advice.

PrivateScans includes a post-scan GP consultation to help you discuss the report and understand recommended next steps. This support is designed to help you make sense of the findings, but further treatment or specialist care may still be needed depending on the result. Ask who is responsible for arranging any additional investigation or referral.

What the report usually contains

A radiology report commonly describes the technique used, the area examined, the main findings and an impression or conclusion. The technique section may note whether contrast was used. The findings section describes what the radiologist sees, while the conclusion summarises the most important points and may recommend follow-up. The layout and wording vary between providers.

A report may use terms such as “unremarkable” to mean no significant abnormality was identified, “degenerative” for certain wear-related changes, or “incidental” for a finding unrelated to the reason for the scan. These words need context. A common finding may not explain your symptoms, and a normal report does not always rule out every possible cause.

If follow-up is suggested, ask what the recommendation is intended to clarify and how soon it should happen. Keep the report and images and share them with the doctor looking after your care. Avoid making treatment decisions based on a single phrase without discussing the full report and your medical history.
