Teleradiologist interpretation of radiological studies has become commonplace in after-hours emergency care. These readings are used to guide the care of the patient, to make diagnoses and to perform invasive procedures. Research has concluded there are significant teleradiology misinterpretations which lead to adverse patient outcomes. The study, published in The Journal of Emergency Medicine studied 787 CT scans of various anatomic locations. It compared a teleradiologist interpretation to that of an in-house radiology interpretation. Their findings supported the, "cautious use of teleradiology interpretations".
