Radiology Specialties

In previous blog posts, we've already established that radiologists are highly trained physicians, and we've looked at some of the things that radiologists do. In this week's post, we will look at some radiology specialties.

Radiologists are specialists at diagnosing disease and injury using medical imaging techniques. But there are also many subspecialties of radiology, including:

  • Neuroradiology which focuses on the diagnosis of brain, spinal cord, head, neck, and vascular problems. Some diagnostic tests that neuroradiologists perform include: sinus CT for evaluation of inflammatory disease (sinusitis), neck CT to assess the larynx, lymph nodes and salivary glands, CT and MR angiograms to detect aneurysms, and MRI to evaluate brain tumors, multiple sclerosis, strokes, and neck and back pain.
  • Body Imaging which involves studies of the chest, abdomen and pelvis, including: prostate MRI, cardiac MRI, abdominal CT to identify kidney and ureter stones, lung CT and many more. Ultrasound may be performed to evaluate abdominal or pelvic pain, vascular disorders and for obstetrics.
  • Breast Imaging which uses digital mammography, positron emission mammography, 3D breast tomosynthesis, breast MRI, and breast specific gamma imaging to diagnose and stage breast cancer. Office-based biopsies are also performed, when necessary.
  • Musculoskeletal Imaging, which as the name implies, identifies issues with muscles, bones and joints using MRI and CT. Radiologists who specialize in this field also use MR arthrography to help identify the cause of joint pain, most often in the shoulder.
  • Nuclear Medicine which diagnoses diseases using a radioactive agent -- called a radiopharmaceutical -- along with imaging technology. Nuclear medicine specialists are physicians who have specialized and become board certified in nuclear medicine. Some radiologists also have additional specialized training in nuclear medicine.

  1. I had an arthrogram at Zwanger Pesiri and it helped diagnose my rotator cuff tear. although it was not a pleasant outcome, it was necessary, they did a great job and the doctor who did it was fantastic. i was stiff for a few days after the injection though.

  2. my mother has been using zwanger for her mamographies for years. she swears by them and loves them. they have many dedicated doctors who specialize in the area and the staff treats her great. if you need mammo i suggest zwanger, when i start getting them, i will go there as well
