A lot of times when we think of radiology, the first thing we think of is an X-ray. Someone who takes a picture of our insides to tell us what the heck is going on in there. But radiology isn't just about scans and images, though it's a huge part of it. There are different types and specialties to consider too. Why is radiology such an important part of the healthcare industry? There's a lot more than meets the eye in this profession, so let's get the whole picture (Ha! Puns. See what I did there?)

Let's start with the basics. There are two different types of radiology.

 

Diagnostic Radiology imaging studies, like MRIs, X-rays, Ultrasounds, CT scans, and barium studies, used to diagnose diseases and conditions.

Interventional Radiology are imaging studies, but are guided by imaging to correct an underlying disease or condition.

  • blocking blood clots so they don't move by inserting filters into the veins
  • biopsies of organs and tissue
  • treating uterine fibroids by blocking blood vessels (embolization)
  • fractured spine treatments and injections
  • cardiac arrythmia, pacemakers
  • angioplasty
  • coronary artery stenting 

 

Additionally, Radiation Oncology is a third type. It specifically treats cancer by radiation. These techs work with high doses of radiation to shrink tumors, in a series of visits for short intervals.

Within radiology, you have sub-specialties in diagnostic and interventional.

Nuclear Medicine provides images involving small amounts of radionuclides in their process, including images like PET and SPECT scans.

Neuroradiology works to diagnose and treat brain, sinus, spine, neck, and central nervous system diseases related to aging and degenerative disease, seizures, stroke, cancer, cerebrovascular diseases, and trauma. Imaging techniques commonly used include angiography, myelography, and MRIs.

Vascular and Interventional Radiology works to diagnose and treat diseases using of various imaging technologies, including fluoroscopy, MRI, CT, and sonography. Some of the therapies include embolization, angioplasty, stent placement, and thrombolysis.

Pediatric Radiology uses imaging related to diagnosing, caring for, and managing congenital abnormalities and infant/child-specific diseases.

 

The University of Virginia health system created a helpful infographic discussing the different modalities in radiology:

But what are the most popular specialties for soon-to-be imaging professionals? Great question! According to the Pima Medical Institute the top five radiography specialties are: CT (computed tomography), MRI, (magnetic resonance imaging), Bone Densitometry, Mammography, and Nuclear Medicine. Ultrasound modalities are also very in demand.

But why these? Often, the most popular modalities become an aspiring imaging professional's choice, because of the wide breadth of opportunities. These specialties can often be applied to a variety of settings, including hospitals and outpatient centers. It's also common for imaging professionals to specialize in several different modalities too. It's never a dull moment!

The Importance of Radiology...

Radiology is the main diagnostic tool for many diseases right now. Without radiology, we would have a hard time diagnosing what's wrong with a patient and how to best treat them. An increased range of diagnostics and improved image clarity have made diagnosing more effective more than ever. Hooray, technology!
