What does the field of Radiology focus on?

The field of Radiology primarily concentrates on utilizing radiant energy for both diagnosis and treatment of medical conditions. This encompasses a wide range of imaging technologies, such as X-rays, CT scans, MRIs, and ultrasounds, which allow for visualizing the internal structures of the body. Radiology not only plays a crucial role in identifying diseases and injuries through imaging but also encompasses therapeutic radiology, including radiation therapy for cancer treatment. The focus on radiant energy is key in distinguishing Radiology from other medical fields, as it directly deals with how energy is used to view and address health issues effectively.

Other options are more aligned with different medical specialties—chemical analysis relates to toxicology or pharmacology, cellular studies pertain to pathology or cytology, and genetic examinations fall within the realms of genetics or genomics. Each of these fields has its distinct focus and methodologies, which do not align with the core purpose of Radiology.
