Teleradiology refers to the transmission of radiological images like CTs, digitized X rays, MRIs and ultrasounds from one location to another. This is for the purpose of sharing studies and findings with various other radiologists and physicians who are not physically present at the location where the images are generated. This facilitates the interpretation of these noninvasive studies remotely.

It allows radiologists to provide services without actually having to be at the location of the patient. This is particularly important when a sub-specialist such as an MRI radiologist, neuroradiologist, pediatric radiologist, or musculoskeletal radiologist is needed, since these professionals are generally only located in large metropolitan areas working during daytime hours. Teleradiology allows for trained specialists to be available 24/7.
