Radiology Sub-Specialties


Radiology is a branch of medicine which involves the use of Imaging Techniques such as X-ray, Computed Tomography, Ultrasound, Nuclear Medicine, Positron Emission Tomography, and Magnetic Resonance Imaging to diagnose and treat human diseases. Below are some of the most prominent Radiology subspecialties.

Abdominal Imaging

It entails the use of Imaging Techniques for performing and interpreting pelvic and abdominal procedures such as gastro-intestinal barium procedures, abdominal radiographs, ultrasounds, computed tomography, magnetic resonance imaging e.t.c.

Breast Imaging

This is the use of Imaging Techniques such as Mammography, Magnetic Resonance Imaging, and Sonography for the detection, diagnosis, and treatment of breast cancer and other breast complications.

Cardiac and Pulmonary Imaging

It is the use of Imaging Techniques chief among them being the Computed Tomography Angiogram test and Magnetic Resonance Imaging to evaluate the cardiovascular and respiratory systems.

Genitourinary Tract

This entails the use of Imaging Techniques such as conventional radiology, ultrasound, X-rays, radionuclide scans, computerized tomography scans, and ultrasound to map, study, observe, detect, diagnose, and treat disorders of the urinary tract such as genitourinary tuberculosis, kidney tumors, and renal anomalies e.t.c.

Chest Imaging

It concerns the usage of Imaging Techniques such as plain X-rays, computerized tomography angiography, high resolution helical computerized tomography, fluoroscopy, ultrasonography, nuclear scanning, magnetic resonance imaging and so on to study, map, and observe the lungs and the surrounding structures.

Interventional Radiology

It pertains to the use of Imaging Techniques such as bone biopsies, therapeutic articular and spinal injections to perform minimally invasive surgical procedures on patients in order to treat a variety of disorders.

Musculoskeletal Radiology

It is the use of Imaging Techniques to diagnose and treat injuries or diseases of the bones, joints, spine, and muscles of both children and adults. It is further subdivided into two sub-sections namely diagnostic and interventional. The former entails the use of conventional radiography, ultra-sonography, low dose computed tomography, and magnetic resonance imaging to detect those problems whereas the latter entails the use of bone biopsies, therapeutic articular, and spinal injections e.t.c. to treat those disorders.


It entails the use of Imaging Techniques such as computerized tomography, magnetic resonance imaging, magnetoencephalogram, and positron emission tomography to diagnose and treat the disorders of the brain, neck, spine and the central nervous systems of the human body.

Neuro Interventional

It is a special sub-specialty of Radiology which specifically pertains to the use of Imaging Techniques to treat disorders of the central nervous systems such as stroke and cerebral aneurysm by way of endovascular approaches.

Nuclear Medicine

This is the use of very small amounts of radioactive tracer materials by way of minimally invasive intra-venous injections to diagnose and treat wide varieties of diseases. In this way, just about every other human organ such as the bones, brain, endocrine, heart, lungs, kidneys e.t.c can be appropriately treated.

Pediatric Radiology

It is the use of Imaging Techniques such as nuclear medicine, ultrasounds, magnetic resource imaging, computed tomography, and X-rays to diagnose and treat disorders that ordinarily affect infants, small children, and pregnant women.

Ultrasound Radiology

It entails the use of very high frequency sound waves in order to derive images from the inside of the human body. It is also called Ultrasound Imaging, Ultrasound Scanning or Sonography.


The field of Radiology is pretty diverse as can be deduced from the foregoing discussions. Potential radiologists hence need to conduct very intensive due diligence to acquaint themselves with the precise field of interest.
