What is Radiology?

Radiology is a medical specialty that uses imaging to detect and treat diseases seen within the body. It is done by using different imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography (PET), and magnetic resonance imaging (MRI).

Radiology Sub Specialties:

Different subspecialties of Radiology include:

  • Breast imaging: Diagnosing breast diseases and conditions via mammography, breast ultrasound, breast MRI, or breast biopsy.
  • Cardiovascular Radiology: Diagnosing heart and vascular or circulatory system diseases via x-rays, CT (computed tomography or CAT), ultrasound or MRI.
  • Chest Radiology: Diagnosing chest diseases especially the heart and lungs via x-rays, CT (computed tomography or CAT), Ultrasound, MRI, or lung biopsy.
  • Emergency Radiology: Diagnosing trauma and non-traumatic emergency conditions through x-rays, CT (computed tomography or CAT), Ultrasound and MRI.
  • Gastrointestinal (GI) Radiology: Diagnosing gastrointestinal (GI) or digestive tract (the stomach and intestines) and abdomen via fluoroscopy, x-rays, CT (computed tomography or CAT), Ultrasound, MRI, and GI procedures.
  • Genitourinary Radiology: Diagnosing the reproductive and urinary systems via x-rays, CT (computed tomography or CAT), and MRI.
  • Head and Neck Radiology: Diagnosing diseases of the head and neck via x-rays, CT (computed tomography or CAT), Ultrasound and MRI.
  • Musculoskeletal Radiology: Diagnosing diseases of muscles and the skeleton via x-rays, CT (computed tomography or CAT), Ultrasound and MRI.
  • Neuroradiology: Diagnosing diseases of the brain and nervous system, head, neck and spine via x-rays, CT (computed tomography or CAT), Ultrasound and MRI.
  • Pediatric Radiology: Diagnosing diseases of children via x-rays, CT (computed tomography or CAT), Ultrasound and MRI and procedures such as fluoroscopy, biopsy and drainage of fluid or abscess collections.
  • Interventional Radiology: Diagnosing diseases of patients utilizing minimally invasive interventional techniques using x-rays, fluoroscopy, CT (computed tomography or CAT), Ultrasound or MRI.
  • Nuclear Radiology: Diagnosing diseases of patients who are using trace doses of radioactive material, in which heart, the skeletal system, and most of the body organs are diagnosed. This even includes treatment of hyperactive thyroid gland and thyroid cancer.
