Doctors as a profession, sometimes very much like the police, are through the traces, analysis and deduction, and finally lock the culprit. The difference is that the police are catching criminals, doctors are catching patients. X-rays, CT, MRI and other tests are powerful weapons to help doctors quickly and accurately pinpoint patients. The patient’s desire for quick and efficient help from the doctor depends on, first, the ability to provide adequate, reasonable, and clear quality imaging, and, second, the doctor’s ability to read the film. Here, I will focus on the first issue, how to provide the doctor with valuable images. First, a clear quality image should be taken at your local hospital: second, placed on a professional viewing light, you can ask your doctor to help you take pictures of the lesion, preferably with only one image per shot and no more than three at most: finally, upload to the web and consult with a doctor you trust. Remember, patients are non-professionals and your descriptions may not be professional, subjective or even misleading, but imaging is always objective and real, so to get a swift and accurate diagnosis and treatment opinion from your doctor, you must pay attention and upload your imaging films carefully. Finally, we introduce several common problems that we hope to avoid.
