What is a radiologist?

A radiologist is a doctor who after graduating from 4 years of medical school, completes 4 or more additional years of residency training in the field of radiology. A radiologist learns the physics of X-rays and methods of how to safely use various types of machines to image patients. The radiologist also will focus on learning about the normal anatomy of all aspects of the body and how to interpret the images to diagnose the presence or absence of disease.

Various imaging techniques used today include:

  • X-rays
  • Fluoroscopy
  • Ultrasound
  • Nuclear medicine and Positron Emission Tomography [PET]
  • Computed Tomography [CT]
  • Magnetic Resonance Imaging [MRI]
  • Image-guided vascular and non-vascular interventional procedures
  • Image-guided, minimally-invasive interventional procedures

What is a pediatric radiologist?

A pediatric radiologist is a doctor who after 4 years of radiology residency, completes an additional 1 to 2 years of training specializing in the problems that involve children. This pediatric radiology fellowship focuses on children and young adults up to age 18 years. A pediatric radiologist is specifically trained to recognize and diagnose various diseases in children using the latest and safest methods of medical imaging. Many pediatric radiologists further sub-specialize in areas such as brain, spine and head and neck imaging. They also can sub-specialize in advanced general diagnostic and cross-sectional body imaging such as musculoskeletal and heart imaging, nuclear medicine and interventional radiology.

What is a neuroradiologist?

After 4 years of a radiology residency, a neuroradiologist receives an additional 1-2 years of specialty training that focuses on imaging of the brain, neck and spine in children. Using MRI, PET/CT, Ultrasound, and CT scans, neuroradiologists diagnose diseases or injuries of the brain, neck and spine. The division of Pediatric Neuroradiology at Phoenix Children's Hospital is the only dedicated pediatric neuroimaging group in Arizona. All of the Phoenix Children's neuroradiologists are board-certified radiologists with additional qualifications in neuroradiology.

What is a interventional radiologist?

After 4 years of a radiology residency, an interventional radiologist receives an additional 1-2 years of fellowship training learning minimally-invasive image guided vascular and non-vascular interventional procedures.

Interventional radiologists perform studies such as:

  • Diagnostic blood vessel examinations (angiograms and venograms) that evaluate blood vessels of the brain and body
  • CT or ultrasound-guided needle biopsy
  • Abscess or fluid drainage
  • Vascular access line [PICC or central line] and port placement
  • Balloon angioplasty and vascular stent placement
  • Minimally-invasive mechanical and/or drug lysis of blood clot
  • Feeding and gastrostomy tube placement
  • Embolization and sclerotherapy of vascular and lymphatic malformations
  • Many other types of diagnostic and therapeutic procedures

Phoenix Children's Hospital is the home of the only dedicated pediatric interventional service in Arizona, Nevada and New Mexico.

What is a nuclear medicine radiologist?

After 4 years of a radiology residency, a nuclear medicine specialist receives additional specialty training of 1 to 2 years in the use of internal radiation known as isotopes or radiopharmaceuticals, which evaluate the function of the heart, the brain, the skeleton, the lungs, the liver and spleen, the kidneys, the thyroid gland and other organs of the body. PET imaging involves the use of newer isotopes in conjunction with other imaging devices such as CT or MRI for very accurate detection of the presence of tumor and other problems in the body. All Phoenix Children's nuclear medicine physicians are specially trained in pediatric radiology as well as nuclear medicine and PET imaging, either board-certified in nuclear medicine or nuclear radiology, and are members of the Society of Nuclear Medicine.

In addition, they are also fellowship trained in pediatric radiology, nuclear medicine and/or neuroradiology. This training goes along with subspecialty certification in diagnostic pediatric radiology, nuclear medicine, neuroradiology or vascular interventional radiology. Our radiologists have also performed significant research, have received additional training in more specialized areas such as:

  • Nuclear medicine
  • PET/CT
  • Advanced musculoskeletal and sports imaging
  • Advanced body imaging in CT or MRI
  • Cardiac imaging
  • Vascular and interventional procedures
  • Neuroradiology
  • Spine imaging
