What is a DICOM file?

A DICOM file is an image saved in the Digital Imaging and Communications in Medicine (DICOM) format. It contains an image from a medical scan, such as an ultrasound or MRI. DICOM files may also include identification data for patients to link the image to a specific individual.

The DICOM format was developed by the National Electrical Manufacturers Association (NEMA). It was designed to exchange and view medical images, such as CT scans, MRIs, and ultrasound images.

The initial DICOM standard was initially released in 1983 and went through various revisions in the 1990s and 2000s. NEMA still actively maintains the format.

NOTE: DICOM images more commonly use the .DCM extension.

How do I open a DICOM file?

You can open DICOM files with various applications, such as MicroDicom viewer (Windows), ezDICOM (Windows), OsiriX (macOS), and MeVisLab (multiplatform). You can also upload DCM files to View My Scans and Jack Imaging in a web browser and view the images.
