Teleradiology is the transmission of radiological patient images, such as x-rays, CTs, and MRIs, from one location to another for the purposes of interpretation or consultation with other radiologists and physicians. Teleradiology improves patient care by allowing 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 a 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.
