You can view your MRI online without installing anything: open the disc, folder or ZIP from the hospital with the buttons above, and MesDICOM shows every series in your browser. Your scans aren't uploaded — they're opened and processed on your computer.
Why does my MRI have so many series?
An MRI study is several scans in one visit. Each series is one sequence — T1, T2, FLAIR, diffusion and so on — often taken in more than one direction, and sometimes again after a contrast injection. Each looks different because each shows tissue differently. That is normal: a head MRI often has ten series or more.
MesDICOM lists them in a rail beside the image. Pick a series, then scroll through its images.
What can I do with my MRI images?
| Tool | What it does |
|---|---|
| Scroll | Moves through the images of a series, with the mouse wheel or the image slider |
| Brightness and contrast | Drag on the image; MR presets for brain T1 and T2, plus full range |
| Zoom, pan, rotate, flip | Look closer or turn the image; double-click to reset |
| Length and angle | Measure on the image, in millimetres when the file carries its pixel spacing |
| Cine | Plays a series as a movie, 5 to 60 frames a second |
| Three planes | Axial, coronal and sagittal views of one series, linked by a crosshair |
| 3D | Five renderings of a volume series, which you can turn and zoom |
| DICOM Info | Patient, study and series details, and every DICOM tag, searchable |
How do I see my MRI in three planes?
Open a series and switch to MPR. MesDICOM builds a volume from the series and shows the axial, coronal and sagittal planes side by side, linked by a crosshair: click in one plane and the others follow. Open any plane full size, measure in it, or change the window for all three.
Three planes and 3D need a series of parallel slices. The clearest results come from thin-slice series; a series taken as a few thick slices still opens in 2D.
Will it open my MRI disc?
Yes, if the disc holds DICOM images, which hospital discs do. Choose the whole disc — not DICOMDIR or the program on it. Step by step: opening a CT or MRI disc.
Which browsers work?
Recent Chrome, Edge, Firefox and Safari on Windows, Mac, Linux and ChromeOS. 3D needs WebGL 2, which most computers have. On a phone, MesDICOM opens DICOM files and ZIP archives.
