| Description | DCM files were created by the National Electrical Manufacturers Association (NEMA) as a standard file format for the creation and storage of various body scans done for medical purposes. The files are now a universal format for viewing patient scans. | JPG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPG typically achieves 10:1 compression with little perceptible loss in image quality. |
| Technical details | DCM files developed by DICOM or Digital Imaging and Communications in Medicine, is a file type created with the aim to distribute and view medical images using a standardized file format. MRI's, CT scans, ultrasound images, and other body scans are stored using this format along with the patient's data and related information. | Image files that employ JPG compression are commonly called "JPG files", and are stored in variants of the JIF image format. Most image capture devices (such as digital cameras) that output JPG are actually creating files in the Exif format, the format that the camera industry has standardized on for metadata interchange. |
