A medical imaging technologist is a health care professional who has been trained to use specialized imaging equipment to assist in the diagnosis of patients. Imaging is a term that refers to a variety of techniques and computer-based machines used to take pictures of the inside of the human body. These images aid doctors in diagnosing or identifying internal problems or illnesses.
Medical imaging technologists come in a variety of shapes and sizes. A radiography imaging technologist is educated in the use of x-rays and other radiation-based diagnostic tools such as computed tomography (CT) scans and magnetic resonance imaging (MRI) scans. A technologist can also specialize in a single field, such as CT or MRI imaging.
A CT scan, also known as a CAT scan, is a type of x-ray that can capture images from various angles. It then stitches the images together to reveal the internal structures in greater detail. Unlike traditional x-rays, this scan provides more information and can image not only bones but also soft tissue and blood vessels.
An MRI, on the other hand, uses a magnetic field and radiofrequency waves. Internal structures can be visualized in clear, detailed images using this scan. It’s also a valuable tool for diagnosing diseases like heart disease, stroke, and cancer.
Sonography is another field in which a medical imaging technologist can work. Sonography, also known as ultrasound, is a diagnostic technique that employs high-frequency sound waves. The image is captured sound waves bouncing off internal structures.
Nuclear medicine is a more complex imaging technique. To capture images, a nuclear medicine imaging technologist employs radiopharmaceuticals, or radioactive medications, as well as specialized cameras and computers. Fluoroscopy training is also available for imaging technologists. A fluoroscope is a radiographic image taken after a contrast medium has been consumed. This solution allows specific body structures to be highlighted in order to capture a detailed image.
Some imaging technologists focus on a particular body part or disease. A sonographer might work in obstetrics and gynecology, for example. On the other hand, a radiographer may choose to work with cancer patients.
Advanced training in imaging techniques and equipment is required for imaging technologists. Depending on the level of expertise and credentialing required, training can range from a one-year certificate program to a four-year degree program. A Post-Baccalaureate degree is pursued some imaging technologists. The majority of imaging technologists work in hospitals or clinics.
