Specialty Groups

By Mayo Clinic Staff

Specialty groups of radiologists, physicists, technologists, nurses and other support staff bring the highest levels of skill and expertise to Mayo Clinic's imaging services.

Computerized Tomography (CT)

In addition to performing high-resolution diagnostic exams of the abdomen and pelvis, abdominal radiologists use computerized tomography to perform CT-guided biopsies that generally involve minimally invasive techniques during local anesthesia or mild intravenous (IV) sedation. Imaging subspecialists perform organ transplant evaluation and noninvasive CT angiography exams of your arms and legs. They also perform cryoablation and radiofrequency ablation (RFA) of noncancerous (benign) and cancerous (malignant) bone tumors during CT guidance.

Cardiothoracic Imaging

Cardiothoracic radiologists interpret X-rays and CT images of the chest, including high-resolution chest CT scans. They also evaluate CT images of your coronary arteries and pulmonary arteries, and magnetic resonance imaging (MRI) examinations of your heart.

Breast Imaging

Breast imaging specialists perform and interpret mammograms, ultrasounds and MRIs of the breast. They also perform cyst aspirations, abscess drainages, core needle biopsies (using mammographic, ultrasound or MRI guidance), ductograms and preoperative radioactive seed localization procedures.

Gastrointestinal Radiology

Members of the Gastrointestinal Radiology specialty group perform fluoroscopic examinations of your esophagus, stomach, and small and large intestines. The group works cooperatively with speech pathologists to aid in the evaluation of swallowing. It also use MRI to evaluate your intestinal tract and perform and interpret CT colonography exams.

Interventional Neuroradiology

Specialty group members perform procedures of the head and spine including carotid stent placement, intracranial and extracranial embolization, intracranial thrombolysis, endovascular treatment of intracranial aneurysms and vascular malformations, and vertebroplasty or kyphoplasty for treatment of spinal fractures. They offer cerebral and spinal angiography and myelography procedures after referral from Mayo Clinic neurosurgeons, neurologists and vascular surgeons.

Interventional Radiology

Interventional radiologists specialize in minimally invasive vascular procedures that can replace open surgery, including aneurysmal stent placement.

Magnetic Resonance Imaging (MRI)

MRI and magnetic resonance angiography specialists perform liver mass evaluation, liver elastography, bile and pancreatic duct imaging, kidney mass evaluation, breast mass and implant evaluation, cardiac imaging, vessel and circulation evaluations, musculoskeletal system, joint evaluations and arthrograms, prostate imaging, neurological disease evaluation and tumor imaging.

Musculoskeletal Radiology

Members of the Musculoskeletal Radiology specialty group perform and interpret radiographs of bones and joints; fluoroscopic, CT- and ultrasound-guided joint injections; aspirations for diagnosing and treating joint conditions; conventional, CT and MR arthrograms; bone mineral density; body composition exams; and MRI and CT scans of the musculoskeletal system.


Neuroradiology group members perform MRI and CT imaging of the head and neck, brain, spine and spinal cord. They also offer imaging that involves CT perfusion and MR perfusion and diffusion imaging.

Nuclear Cardiology

Members of the Nuclear Cardiology specialty group work with those of the Nuclear Medicine specialty group to evaluate coronary artery disease, acute chest pain, hibernating myocardium and cardiomyopathies.

Nuclear Medicine

Nuclear Medicine radiologists interpret bone and lung scans, myocardial stress-rest perfusion SPECT and other tests, as well as dynamic studies during gastrointestinal bleedings.


Ultrasound specialists produce moving video images of internal organs, including abdominal and pelvic organs, blood vessels and soft tissues. Particular expertise includes gynecologic imaging; thyroid nodule diagnosis and fine needle aspiration; targeted biopsy; radiofrequency and cryoablation; transplant evaluation; and carotid sonography.
