Introduction

Radiology, derived from the Latin word “radius” meaning ray, is a medical specialty that employs imaging techniques to visualize the internal structures of the body. From the discovery of X-rays by Wilhelm Roentgen in 1895 to the cutting-edge technologies of today, radiology has evolved into an indispensable tool in the field of healthcare. This article delves into the multifaceted world of radiology, uncovering the breadth of imaging modalities, the transformative impact of technology, and the crucial role it plays in modern medical practice.
