What is a Diagnostic Radiologist?
Diagnostic radiologists are medical doctors (MDs) or doctors of osteopathic medicine (DOs). They employ a range of imaging techniques to explore the body and evaluate or diagnose the patient's condition. They are responsible for interpreting the results of medical imaging procedures using X-rays (radiography and CT), magnetic fields (MRI), ultrasound (sonography), and radioisotopes (nuclear medicine).
Your radiologist is a key player in your health because they serve as an expert adviser to your referring physician (the physician who ordered the test), helping them choose the best exam and guiding radiology technologists (those who operate the equipment) in carrying out high-quality exams. They give the radiology technologists detailed directions for each patient and condition to ensure that the images produced are as clinically beneficial as possible. They analyze the images that are produced and present their findings, prescribing treatment and, only when necessary, additional testing.
After receiving their medical degree and completing a year of medical school, aspiring radiologists must undergo at least four years of resident training in radiology. Fellowship studies in more specialized fields of radiology are often completed by doctors who want to become subspecialists. Through substantial clinical practice and accompanying research, diagnostic radiologists can also become specialists in the following radiological subspecialties:
- Breast imaging (mammograms)
- Cardiovascular radiology (heart and circulatory system)
- Chest radiology (heart and lungs)
- Emergency radiology
- Gastrointestinal radiology (stomach, intestines and abdomen)
- Genitourinary radiology (reproductive and urinary systems)
- Head and neck radiology
- Musculoskeletal radiology (muscles and skeleton)
- Neuroradiology (brain and nervous system; head, neck and spine)
- Pediatric radiology (imaging of children)
Tests and Procedures
Computed Tomography
The diagnostic radiologist creates high-resolution images of bodily tissues, organs, and arteries using CT imaging (also known as "CAT scan"). Multiple tissue types, including blood vessels, soft tissue, bone, and the lungs, can be seen on a CT scan.
Magnetic Resonance Imaging
Strong magnetic and radio waves are used in MRI to generate detailed images of organs and tissues, including ligaments, cartilage, and nervous system structure. When it comes to identifying diseases like cancer, heart and vascular disease, stroke, and musculoskeletal issues, MR imaging can be extremely helpful.
X-rays
X-rays can be used in a variety of ways to diagnose and treat medical diseases. Digital X-rays, which are now accessible in some facilities, subject patients to less radiation than traditional X-rays. They also produce fewer repetitions, are faster and more comfortable, and offer better image quality and clarity.
CT Angiography and MR Angiography
Both CT angiography (CTA) and MR angiography (MRA) are minimally invasive diagnostic procedures used to identify blood flow-related problems in patients who may or may not exhibit symptoms. These cutting-edge imaging techniques are used by radiologists to advise referring physicians about the condition of the blood vessels in the brain and those that deliver blood to the heart, lungs, kidneys, arms, and legs.
Mesenteric CT Angiography and MR Angiography
The blood vessels associated with the small and large intestines are examined using standard CT and MRI techniques.
Nuclear Medicine
Nuclear medicine creates two-and three-dimensional images of internal organs and body structures to examine their function. It does this by using small amounts of radioactive chemicals. To assess medical issues, a nuclear scan may or may not be used in conjunction with CT imaging.
Positron Emission Tomography
PET scanning is a nuclear medicine modality that involves injecting a radioactive substance to provide a three-dimensional image of physiological systems and function.
Pulmonary CT Angiography
Pulmonary CTA is often used to assess and diagnose patients in the emergency room, especially those potentially having a fatal pulmonary embolism or blood clot in a blood vessel of the lung.
Renal CT Angiography and MR Angiography
These angiography techniques are used to spot irregularities in the kidney arteries.
Ultrasound
High-frequency sound waves are used in ultrasound imaging, also known as sonography, to produce images of internal organs and structures.

Healthcare Delivery by Diagnostic Radiologists in the US
Diagnostic radiology and interventional radiology are subspecialties of radiology training, and doctors in these fields have varying levels of training and expertise. It utilizes imaging technologies and nuclear medicine to diagnose and assess illnesses and injuries inside the body. It is a subspecialty of radiology, the medical specialty that uses imaging to diagnose and treat disease overall.
Diagnostic radiology can be used to identify and treat a wide range of illnesses and problems. The kind of imaging a person requires typically relies on how severe their symptoms are and how healthy they are in general.
According to Castle Connolly Top Doctor Burton A. Cohen, MD, an associate clinical professor of radiology at Mount Sinai Hospital in New York City, patients with symptoms like severe or persistent abdominal pain, a persistent cough, shortness of breath, irregular menstrual bleeding, or postmenopausal bleeding are most frequently referred for diagnostic radiological screening.
To be able to provide the finest patient care while on the job, radiologists study for more than ten years to master the ins and outs of examination methods, anatomy, equipment procedures, and radiation protection. Diagnostic radiology can be used to diagnose a wide range of issues. Diagnostic imaging can detect issues ranging from blood clots and broken bones to heart diseases and digestive issues.
However, diagnostic radiology isn’t just utilized for diagnosing problems. Diagnostic radiology can also be used by medical professionals to track how a patient's body is responding to a particular course of treatment. Diagnostic radiology can also be used to check for conditions including breast and colon cancer.
As technology advances, there will be a growing need for radiologists who are knowledgeable about how to integrate computer-based imaging and modeling into conventional healthcare and treatment practices. After graduating from medical school, radiologists who work to understand this expanding field can anticipate having a wide range of career options.
