The field of radiology is more expansive than most people think. In fact, radiology can diagnose, visualize, and treat a disease一 all with the same technology. Let’s take a look at the three different types of radiology and what they are used for within the field of medicine.

The 3 Types of Radiology

What Is Therapeutic Radiology?

Also known as radiation oncology, therapeutic radiology serves as a type of treatment for various diseases and conditions. Therapeutic radiology uses ionizing radiation to intentionally damage and destroy troublesome cells in a patient’s body. This type of radiation is extremely targeted and high dosage. This can lead to some unpleasant side effects, but fortunately, the benefits usually far outweigh the risks一 especially for patients sick with cancer. Radiation oncology is one of the areas we specialize in at our office.

What Is Diagnostic Radiology?

This type of radiology is only used to create images of a section of the patient’s body, allow doctors to observe and diagnose the possible problem. Radiologists use machines like x-rays and CTs to produce images that a surgeon or other specialist will then use to develop a treatment plan. In this way, the radiologic images serve as diagnostic material to aid the specialists as they formulate a diagnosis and treatment plan for their patients. Here at Rosetta Radiology, we offer a wide variety of diagnostic imaging services.

What Is Interventional Radiology?

Interventional Radiology is a sort of mash-up between diagnostic and therapeutic radiology in the sense that interventions often both view and treat a condition at the same time. For example, a specialist trained in radiology methods can use x-rays to visualize the precise insertion of a catheter into an artery. This way, the procedure can be accomplished without surgical incisions and the complications associated with invasive procedures for some patients.

Diagnostic Radiology vs Interventional Radiology:

As hinted at above, diagnostic radiology serves only to visualize the patient’s body so that a diagnosis can be made. In contrast, interventional radiology combines both treatment and visualization into one effective service. One example was used above, but another would be direct treatment of a tumor (ablation), where the tumor would be visualized with radiology techniques, and the tumor would be treated with microwaves, freezing, or other methods.


Here at Rosetta Radiology, we offer three distinctive radiology services: diagnostic imaging, women’s imaging, and radiation oncology services. Combined with onsite radiologists, prior authorization, quicker turnaround times, and more benefits, we believe you’ll be proud to call Rosetta Radiology your go-to for radiology services in Manhattan.
