Radiologist

When you have a mammogram, an MRI, or a CT scan, the images are reviewed by a radiologist — a physician who has spent four or more years after medical school studying how disease looks on imaging. Radiologists are trained to spot subtle patterns that indicate cancer, fractures, infections, or vascular abnormalities that would otherwise be invisible without surgery.

Although you may never meet your radiologist face-to-face, their written report plays a central role in your diagnosis. They communicate findings using standardized language — for mammograms, a system called BI-RADS assigns a category that guides whether you need additional imaging, a biopsy, or routine follow-up. For other studies, their report describes size, location, and characteristics of any findings in precise clinical terms.

Some radiologists also perform procedures — like image-guided biopsies or drain placements — using real-time imaging to navigate inside the body with minimal invasiveness. Interventional radiologists in particular specialize in these techniques. Whether reading films or performing procedures, the radiologist works closely with your broader care team to ensure the right next steps are taken based on what the images reveal.

The radiologist's interpretation is often the pivotal step between taking an image and knowing what it means. A skilled reading can catch a tumor at an early, highly treatable stage, identify a finding that needs prompt follow-up, or reassure you that something is benign. Accuracy in this step directly affects treatment decisions and outcomes.

If you ever feel uncertain about an imaging result, it is entirely reasonable to request a second opinion from another radiologist, particularly at a major academic or specialty center. Your report is a medical document you are entitled to receive, and understanding what it says — or asking your doctor to walk you through it — puts you in a stronger position to participate in decisions about your care.
