“Too many radiologists still believe there is a risk from a chest X-Ray. Few radiologists can explain the radiation to the patient in words the patient can understand”. ~John Cameron Radiology is the science that uses medical imaging to diagnose and treat diseases seen within the body. A variety of imaging techniques such as X-ray Radiography, Ultrasound, Computed Tomography (CT), Nuclear Medicine including Positron Emission Tomography (PET), and Magnetic Resonance Imaging (MRI) are used to diagnose and/or treat diseases. Interventional radiology is the performance of (usually minimally invasive) medical procedures with the guidance of imaging technologies. Radiography is a paramedical professional course, offered to individuals who will at some point of time, perform diagnostic tests in medical treatment with the use of radiation. In simple terms, radiography may be described as the science of taking images of the internal and hidden portions of the human body for the purpose of diagnosing diseases and ailments. This includes the use of ultrasound, X-ray, CT scan, MRI, etc. A radiographer who can perform the ultrasound test as well is known as Sonographers.

Radiologist Overview

• A radiologist is a physician who specializes in the analysis of images of a body. They would make use of a range of investigative techniques, such as x-rays and ultrasound scans. The work of a radiologist is of utmost importance in the diagnosis of patients, and is crucial to the application of rapid and essential treatment. Such professionals would need to work face-to-face with patients in order to carry out testing, and would need to ensure the patient’s safety is taken care of. The medical conditions a radiologist would deal with include cancer and fractures.

Typical work activities a radiologist would need to carry out include the following:

• Carry out investigative techniques and treatments such as x-rays, ultrasound scans, chemotherapy, radioactive isotopes and hormone therapy.
• Put patients at ease during testing and ensure that they understand the process involved.
• Analyse and interpret test results and decide upon a diagnosis as soon as possible.
• Work with a host of medical professionals from different specialties.
• Work in hospitals, specialist testing centers and for private organizations, such as the armed forces.
• Keep up-to-date with any advances in the diagnosis of patients through medical imaging.
• You will not only need a good understanding of testing techniques, but also medical applications.
• Work with patients throughout their recovery, particularly when working with those who have cancer.
