Our resident troll, OC, has been insisting that most doctors don't show x-rays and ultrasounds and other medical imaging results to patients prior to treatment. But my experience has been otherwise.
I've had two dental procedures done within the past month. Both dentists showed me the x-rays and explained why they were recommending the treatment they were about to do. In fact, I don't recall a single dentist who failed to show me the x-ray and point out the problem and explain what they were going to do. That includes the dentists I went to in Korea who didn't share a language with me and had to go through a translator.
I recently had a suspicious mammogram. The doctor showed me the films and the mass. He explained what he was recommending and why. I watched realtime as he did the ultrasound. He explained what he was seeing and pointed the mass out to me and explained why he wanted to do a biopsy. I watched the ultrasound during the biopsy, and again the doctor explained what he was seeing and what conclusions he was drawing.
Every family member or friend I can recall who had diagnostic imaging done was shown the diagnostic image. This is particularly true in obstetrics, where I've never heard of not showing the ultrasound to the patient unless the ultrasound is being done for an elective abortion.
What have your experiences been?
