About Radiology
What is a Radiologist?
Radiologists are specialist physicians who use medical imaging to diagnose and guide the treatment of disease — often working behind the scenes to support your care.
When your doctor orders an X-ray, MRI, CT scan, or ultrasound, it is a radiologist who interprets the images and provides the expert analysis that shapes your diagnosis and treatment plan. Though you may never meet your radiologist in person, they play a vital role in your healthcare team.
What Does a Radiologist Do?
Radiologists are medical doctors who specialise in diagnosing and treating diseases and injuries using medical imaging techniques. They analyse images from X-rays, CT scans, MRI, ultrasound, mammography, and other modalities, then provide detailed reports to your referring physician. In some cases, radiologists also perform minimally invasive procedures guided by imaging, such as biopsies or drainages.
- Interpret diagnostic images (X-ray, CT, MRI, ultrasound, mammography)
- Provide written reports to referring physicians with findings and recommendations
- Consult directly with physicians on complex or urgent cases
- Perform image-guided procedures such as biopsies, injections, and drainages
- Oversee radiation safety and ensure imaging protocols are appropriate for each patient
How Are Radiologists Trained?
Becoming a radiologist requires extensive medical training. After completing a four-year medical degree, radiologists undertake a one-year internship followed by a four-year residency in diagnostic radiology. Many then complete an additional one to two year fellowship in a subspecialty such as neuroradiology, breast imaging, interventional radiology, or musculoskeletal imaging. Board certification from the American Board of Radiology confirms that a radiologist has met rigorous standards of knowledge and skill.
How Are Radiologists Different from Other Doctors?
Unlike most physicians who see patients directly in a clinic or hospital ward, radiologists primarily work with images. They are expert consultants — your doctor's doctor. When a clinician is uncertain about a diagnosis or needs to rule out a serious condition, they rely on the radiologist's expertise to interpret the imaging evidence. Radiologists are also uniquely trained in radiation physics and safety, ensuring that every imaging exam uses the lowest dose necessary to achieve a clear result.
The Radiologist's Role in Your Care
Even if you never speak directly with a radiologist, their work is central to your care. The report they produce after reviewing your images often determines whether you need further tests, a referral to a specialist, or a change in treatment. At Golden Gate Radiology, our board-certified radiologists are committed to delivering accurate, timely interpretations — and are always available to consult with your physician when questions arise.
