What is the difference between diagnostic radiology and interventional radiology?

The distinction between diagnostic radiology and interventional radiology primarily revolves around the purpose and utilization of imaging techniques. Diagnostic radiology is dedicated to the interpretation of images obtained through various modalities such as X-rays, CT scans, MRIs, and ultrasounds. The primary aim here is to detect, diagnose, and monitor diseases and conditions by interpreting these images, allowing healthcare providers to make informed decisions regarding patient care.

In contrast, interventional radiology incorporates imaging techniques not only for diagnosis but also for guiding minimally invasive surgical procedures. While this specialty utilizes imaging as a critical tool, it primarily focuses on using various instruments to treat different medical conditions, such as performing biopsies, placing catheters, or performing embolizations.

The incorrect choices highlight misunderstandings of these specialties. For example, interventional radiology does not limit itself to ultrasound; it employs various imaging techniques (such as fluoroscopy, CT, and MRI) to guide procedures. Moreover, diagnostic radiology does not engage in surgical procedures, as that is a core activity of interventional radiology. Lastly, interventional radiology is fundamentally tied to imaging, as imaging is essential to guide the procedures performed, contradicting the assertion that it does not involve imaging.
