Radiology is an ever expanding field of medicine. Radiologists are required to have a broad knowledge base and must use that knowledge, as well as, a solid strategy to evaluate each case and arrive at the correct diagnosis. Radiologists use a three step pattern of analysis in the evaluation of each case to help reach the appropriate diagnosis. The first step, known as pattern recognition, is identification of the proper pattern after analyzing the clues available on the diagnostic images.

... , is the formulation of a well-constructed differential diagnosis based on experience and the pattern recognized in the first step. And finally, is the arrival at the most likely diagnosis by narrowing the differential diagnoses using the patient's clinical and laboratory findings. This process, known as "triangulation", forms the backbone of diagnostic radiology. Using this approach the radiologist can help the referring clinician by providing a pertinent diagnosis or list of possible diagnoses that will help guide the patient's treatment. Recent years have witnessed significant advances in the technology of medical imaging. Some of the most important advances have occurred with regard to imaging of the brain and spinal cord. Neuroradiology has been one of the most rapidly evolving disciplines formulate a differential diagnosis and present the final diagnosis with histologic correlation when available. Please remember, these are challenging cases, many of which I, myself, found difficult. Therefore, do not feel discouraged if you cannot make the correct diagnosis. However, if you do arrive at the proper diagnosis, be proud of yourself. The participant with the most correct diagnoses will be awarded a special prize. S66 1998年5月 Curriculum Vitae (Simplified)
