People are typically referred to a radiologist by their primary care physician or an attending physician at a walk-in clinic or urgent care. Depending on the patient’s symptoms, and as a result of a physical exam, the doctor will make a determination on the need for further diagnostic testing to help make a complete and accurate diagnosis. Radiology covers many different forms of diagnostic imaging such as x-rays, ultrasound, CT scans, and MRI’s that can be done to diagnose diseases or medical conditions. Diagnostic imaging tests are typically performed by a radiographer, who is a trained specialist in the technical use of the equipment used to perform the diagnostic tests. The radiologist is a trained medical doctor that is able to choose the best diagnostic test for the patient based on the condition or disease that they are being tested for. They can also interpret the results of the test and then consult with your primary care physician on the best course of action for treatment. Patients can also consult with their doctor on an ongoing basis when radiology techniques are used as part of a treatment plan to monitor the success of an existing treatment method.
