MRI scan analysis

Understand Your MRI Images with AI

Upload images from your MRI — a DICOM folder from the hospital disc or exported JPG/PNG files. The AI explains what the selected images show in plain language, next to a clinical-style report. Your first analysis is free with a free account, and you can ask follow-up questions about the report in a chat.

This page analyses images. If you have the written MRI report, add it (PDF or photo) as optional context next to the images; a report on its own is not analysed.

Before you upload

File formats.: DICOM — a whole folder, several files or DICOMDIR (.dcm, .ima, .img or no extension) — or JPG, PNG and WebP images. Exported files work best; a phone photo of a screen carries less detail and may be flagged as low quality.
Account.: You can choose files and fill in the form without signing in. The images are first checked to confirm they are a medical scan; before the analysis itself runs, you log in or create a free account.

🧠 Simplified Explanation

⚠️ Seek immediate medical attention

Brain MRI with T1, T2, FLAIR, DWI, ADC and post-contrast T1 sequences. A large complex growth is visible in the left temporal area with surrounding swelling causing a midline shift. The AI identified 6 specific observations.

Clinical Summary

Axial MRI brain with T1, T2, FLAIR, DWI, ADC and post-contrast T1 sequences. Images are of diagnostic quality.

💬 A detailed brain scan using multiple imaging techniques. Each technique highlights different types of tissue — combined, they give a comprehensive picture of the brain.

Follow-up questions

This looks very serious. What should I do right now?

This finding is urgent and requires immediate medical attention. Please contact your doctor or go to an emergency department today. Bring this report with you.

Radiology Findings6 findings

Large, complex left temporo-parietal intra-axial mass.

1→ In the left part of the brain there is a large, irregular growth sitting inside the brain tissue itself.

Heterogeneous signal on T2 and FLAIR, with areas suggestive of necrosis or cystic change.

2→ Inside the growth, some areas appear to be dead tissue or fluid — suggesting it is growing rapidly and aggressively.

Significant surrounding vasogenic edema.

3→ The brain around the growth is very swollen. This is the brain's reaction to the pressure and causes additional symptoms.

Mass effect with midline shift.

4→ The growth is large enough to push brain structures out of their normal position — a sign of serious pressure inside the skull requiring urgent evaluation.

Patchy areas of restricted diffusion on DWI/ADC.

5→ Certain areas of the growth show abnormal water movement — consistent with very active or densely packed tumour cells.

Irregular, heterogeneous enhancement post-contrast.

6→ After contrast dye was injected, the growth lit up unevenly — a pattern typical of aggressive tumours with disrupted blood vessels.

Impression

PRIMARYHigh-grade intra-axial neoplasm (e.g. Glioblastoma multiforme).

2Metastatic disease.

3Abscess.

4Primary CNS lymphoma.

💬 The most likely explanation is an aggressive brain tumour. This requires immediate verification by a neurologist or neurosurgeon — only a biopsy can confirm. Other possible explanations include cancer spread from elsewhere, an abscess, or a rarer tumour type.

Next Steps & Recommendations

Biopsy for definitive histopathological diagnosis.

1→ A small sample of tissue needs to be taken and examined under a microscope — the only way to confirm exactly what type of growth this is.

Neurosurgical consultation for potential resection.

2→ A brain surgeon needs to evaluate whether the growth can be safely removed or reduced in size. Book an urgent appointment today.

Clinical correlation with neurological symptoms.

3→ Tell your doctors about all symptoms — headaches, vision or speech changes, weakness, confusion. This information helps plan treatment urgently.

Learn about MRI and how the analysis works

What is magnetic resonance imaging (MRI)?

MRI uses a magnetic field, radio waves and a computer, not X-rays, to create detailed images of the inside of the body.

What the examination shows depends on the scan itself. This tool does not perform or repeat the examination; it only explains the images you upload.

How sequences differ — further down this page

How does AI analysis of MRI images work?

One analysis is one submission of up to 10 images, read together; they can come from one series or several. From a DICOM folder, the tool first pre-selects evenly spaced images, and you can change the selection.

The AI (Google's general-purpose Gemini model) receives only the pixels of those images and the details you enter: age, sex, notes and an optional attachment. It does not receive the DICOM metadata, the other slices or a 3D volume.

You get a written report: a plain-language explanation next to clinical-style sections (findings, impression, next steps). It is an AI explanation to help you understand the images and prepare questions, not a diagnosis or a radiologist's report.

What you can do with your MRI images

Analyse selected images

Up to 10 images in one analysis, read together. Images you do not select are not analysed.

A report in clinical and plain language

A plain-language explanation next to clinical-style sections, as PDF or Word. It is not a diagnosis.

Ask about your result

Ask follow-up questions about your full report. The chat does not change the report or replace a doctor.

Combine images from several sequences

Mix images from different series in one analysis. The tool does not recognise series by itself, so note them in the form if you know them.

Information by body area

Each body area is scanned with its own set of sequences and has its own report vocabulary. Start here if you know which part was scanned.

One study, several sequences

KNEE_MR_2026 — 6 series, 312 images

Fluid is dark on T1 and bright on T2. A finding visible on one sequence can be invisible on the next. Which series a sentence in the report refers to changes what that sentence means.

Words that only appear on an MRI report

T1 / T2 weighting: Two ways of timing the measurement. Fat is bright on T1; fluid is bright on T2. The same tissue, two different pictures.
FLAIR: A T2 image with the signal from free fluid suppressed, so changes next to fluid-filled spaces stand out. Common in brain studies.
DWI / ADC: Diffusion imaging and the map computed from it. They are read as a pair — bright on DWI means little on its own.
Fat saturation (fat-sat, STIR): Fat signal deliberately removed so that swelling and oedema in bone and soft tissue become visible.
Gadolinium: MRI contrast agent. Post-contrast series are labelled separately; comparing them to the pre-contrast series is the point.
Motion artifact: Smearing from movement during a sequence that can take several minutes. Frequently noted in the report itself.

What an MRI does not show

Stated up front, because it bounds anything read from the images.

Cortical bone and fresh calcification are poorly seen. CT is the study that answers those questions.

A sequence that was not acquired cannot be inferred. If the exam has no post-contrast series, no reading adds one.

Metal implants. They can cause artefacts and make parts of the images harder to assess.

One exported image is one sequence at one slice. A phone photo of a screen carries less again.

Frequently asked questions

What MRI file formats can I upload?

A DICOM (.dcm) series as a folder or multiple files, or individual MRI images already exported as JPG or PNG.

How many images from my MRI are analysed?

Up to 10 per analysis. One analysis is one submission of up to 10 images, read together, from one series or several; images you do not select are not analysed. From a DICOM folder the tool pre-selects evenly spaced images, and you can change the selection. To have more images explained, start another analysis.

Do I need an account, and what is free?

Yes, a free account is required before the analysis runs. A new account (one per email address) gets one free analysis with the full report, including follow-up questions in the chat. Further analyses are paid.

What do T1 and T2 mean on my MRI report?

T1 and T2 are two common ways an MRI machine can capture the same tissue. T1-weighted images show fat and anatomy clearly; T2-weighted images make fluid appear bright, which helps highlight swelling or inflammation.

Why does my MRI report mention ‘sequences’?

A sequence is one specific scanning technique used during your MRI (for example, T1, T2, or FLAIR). A single MRI study usually combines several sequences to show different types of tissue detail.

Can I upload an MRI without contrast?

Yes. Contrast (gadolinium) is not required. The AI receives only the pixels of the images you select and the details you enter (age, sex, notes, an optional attachment), not the file's technical data (DICOM metadata). It can therefore say whether contrast was used only if the images themselves or your notes show it, for example if you write which series is post-contrast.

What will my MRI analysis report include?

Your MRI analysis report includes a Simplified Explanation in plain language, plus clinical Findings, Impression, and Next Steps & Recommendations.

How long do you keep my uploaded scan?

Uploaded images are deleted 30 days after upload. Deleted files may remain in a recoverable backup for up to 7 more days. Original DICOM files, additional images and attachments are not stored by us: only one image per analysis is kept, for those 30 days. Your report and chat stay in your account until you delete them.
