Our first meeting with professor De Schepper was a memorable one. He was a dashing, young assistant professor of radiology at the University of Antwerp, full of energy and new ideas, and he was teaching an introductory radiology course to medical students. All of us were fascinated by the inner world of the human body, which became visible through radiological techniques. The year was 1978. Radiology was completely different from what it is now. Computed tomography was still in its infancy, and in Belgium there were at that time only two CT units. Ultrasonography was a cumbersome technique, producing grainy images, and MRI was non-existent. So the course focused mainly on conventional radiological techniques. But, Arthur De Schepper introduced a clinical symptom-based approach to radiology, an algorithmic approach avant la lettre. In this way, we had lessons about: the patient with right lower quadrant pain, the woman with a lump in the breast, a man with low back pain, etc. As medical students we loved his classes, and – unlike those of some of his colleagues – they were very well attended.
