Radiology - Introduction

Radiology is a medical specialty that uses medical imaging to diagnose and treat diseases or injuries within the human body. Imaging procedures are used to create pictures of the tissues, organs and bones in the body. A number of different imaging exams can be used to provide this view, including X-ray, ultrasound, computed tomography (CT), Magnetic resonance Imaging and Positron emission tomography (PET). By viewing an image, doctors get to diagnose medical conditions and injuries, such as cancer, fractures, and blood clots.

Radiology is the key diagnostic tool for many diseases, it is not possible to manage patient without diagnosing imaging. It not only helps with monitoring treatment but also helps with predicting specific outcomes. When a physician is not sure about certain problem his patient is having, he will consult the radiologists to try and figure the problem out. This ability of diagnosing disease and other injuries has made radiology necessary for medical care.


Radiologists are doctors who specialize in using medical imaging to diagnose and treat people with various conditions. They apply advance knowledge of anatomy and pathology to interpret the findings of medical imaging examinations, and to assist other doctors and health professionals with the diagnostic reports. Once the results have been obtained and interpreted, these are taken to the patient’s doctor and advice is offered.
