- 1. Radiology is a medical specialty that uses imaging techniques such as X-rays, CT scans, MRIs, and ultrasounds to diagnose and treat diseases within the body. Radiologists are doctors who interpret these images to help other healthcare providers make accurate diagnoses and develop treatment plans. They play a crucial role in identifying conditions ranging from broken bones to cancerous tumors. Radiology is constantly evolving, with new technologies and techniques being developed to improve the accuracy and efficiency of diagnoses.
