Dr Colin Tan is a General Radiologist based in Wahroonga, NSW. He works at Suite 407, San Clinic, Sydney Adventist Hospital, 185 Fox Valley Road, Wahroonga NSW 2076. Radiology can sound a bit technical, but the job is pretty simple: use imaging to help doctors work out what’s going on, and to guide the next steps for care.
Dr Tan provides a range of imaging services, including X-rays, ultrasounds, mammograms, and bone density scans. These tests are used for many everyday health situations. For example, X-rays can help with things like injuries and ongoing chest or breathing concerns. Ultrasound is often used to look at organs and soft tissue, and it can be helpful when symptoms need a clearer picture. Mammograms are used for breast screening and assessment. Bone density scans support checks for bone health, especially where fracture risk may be a concern over time.
People come in with all sorts of reasons for needing imaging. Sometimes it’s part of a health check, other times it’s because symptoms have shown up and the doctor wants answers. At times, results can bring relief, and at other times they can raise questions. Imaging reports are just one piece of the puzzle, but they can make a big difference to how quickly your treating team can plan what happens next.
In many cases, radiology is about being accurate and careful. Images need to be clear, and details matter. Dr Tan’s role is to review scans and provide findings that help the referring doctor understand the situation. Appointments are also a chance to ask questions about the test itself, how long it takes, and what you need to do before you come in.
