Medical Screening
X-ray imaging can be used for a large variety of medical cases. Some examples are foreign objects that have been digested, breaks/fractures, and pregnancy.
What is a Radiologist
Radiologists are medical doctors that specialize in diagnosing injuries and disease using screen imaging procedures (x rays, tomography, MRI, PET). To become a radiologists, you must complete at least 13 years of training, including medical school, fellowship, nuclear medicine, musculoskeletal imaging, and internships. They must be certified by the American Board of Radiology. Radiologist are often compared to RT's. However RT's perform diagnostic tests on patients, while radiologists interpret the tests/images and prescribe a course of treatment. The fields concerning radiology are plain radiography, fluoroscopy, computed tomography, ultrasounds, magnetic resonance imaging, and nuclear medicine.
Plain Radiography: Radiographs or roentgenographs, named after the discoverer of X-rays(William Roentgen) produced by transmitting X-rays through a patient
Computed Tomography: CT exposes the patient to far more ionizing radiation than a radiograph
Ultrasound: uses high-frequency waves to visualize soft tissue structures in the body in real time
Magnetic Resonance Imaging(MRI): uses strong magnetic fields to align atomic nuclei (usually hydrogen Protons) within body tissues, then use a radio signal to disturb the axis of rotation of these nuclei and observes the radio frequency
Nuclear Medicine: Nuclear medicine imaging involves the administration of radiopharmaceuticals with affinity for certain body tissues labeled with radioactive tracer
