10 Things You Need to Know: Dr Elias Pretorius on RSG

Yesterday, Dr Elias Pretorius from Morton & Partners Radiologists took center stage on RSG’s “10 Things You Need to Know” segment during the Drive Time show with Willem Pelser. In an insightful conversation, he unpacked the world of radiology in a way that was engaging, easy to understand, and sometimes surprising.

Dr Pretorius explained how radiology allows us to look inside the body without surgery — from X-rays and ultrasound to CT, MRI, and mammograms. He shared the fascinating history of the first X-ray, described how modern imaging evolved from simple shadows to crystal-clear 3D insights, and emphasized why radiologists are the “gatekeepers of radiation” in medicine.

He highlighted that radiology is more than just images — it also includes minimally invasive procedures that reduce pain, risk, and recovery time, such as image-guided biopsies, draining infections, and even modern carpal tunnel release through tiny incisions.

Dr Pretorius also addressed the role of AI, clarifying that while technology can help detect patterns and flag findings, the radiologist’s expertise remains irreplaceable. He noted that radiology is everywhere in medicine, supporting over 70% of clinical decisions, and that its future is exciting: faster, safer imaging, more personalized treatments, and even earlier disease detection.
