Overview:
Radiology is a branch of medicine that uses imaging technology to diagnose and treat diseases. Radiologists use various imaging techniques such as X-ray, MRI, CT scans, and ultrasound to visualize the internal structures of the body. The field of radiology is divided into diagnostic radiology and interventional radiology.
A radiologist will look at the outcome of a certain imaging test to find a relevant image that evaluates and supports a diagnosis. These individuals are usually medical doctors (MDs) with highly specialized training focused on the interpretation of medical imaging. Radiologic technologists also aid in this process, as they use and manage the machines in the course of producing an image. After a patient undergoes imaging tests, radiologists will give reports of their interpretations to the referring clinical doctors.
Every sector within the healthcare field relies on radiology, including:
- Surgery
- Pediatrics
- Obstetrics
- Oncology
- Trauma-response
- Emergency medicine
- Infectious disease
In many cases, early diagnosis can save lives, including those of patients diagnosed with cancer. Family doctors and emergency care physicians cannot effectively manage patients without diagnostic imaging, which is why they rely on radiology to find the right diagnosis and course of treatment.
Uses of Radiology:
Radiology is used for a wide range of conditions, and is classified depending on the type of radiology and the exact imaging test used. The various imaging exams include:
Radiographs: X-rays to look at bones, the chest or the abdomen.
CT (Computed Tomography): A CT captures multiple x-ray angles of the patient using a doughnut-shaped machine, then creates computer-processed images.
MRI (Magnetic Resonance Imaging): An MRI uses magnetic fields and radio waves with computer processing to create images.
Mammograms: Specially powered x-rays that look at breast tissues.
Ultrasound: An ultrasound uses sound waves to create moving images that display on a monitor, commonly used for echocardiograms and examining the womb during pregnancy.
Fluoroscopy: X-rays that make moving images of the body in real time. This imaging is crucial for many procedures, especially those involving the gastrointestinal tract.
Nuclear medicine: These are short-acting radioactive substances that generate light from bodily processes. A camera collects the light, so a computer can process it and develop an image.
Diagnostic radiology uses these imaging results to identify a wide range of problems, from broken bones to heart conditions and blood clots. Interventional radiology also uses imaging such as CT scans, MRI and ultrasounds to guide medical procedures. Patients are typically awake during these procedures, whether it’s treating cancer, back pain, or liver and kidney problems. In some cases, interventional radiology eliminates the need for surgery and scopes.
