Radiology can be surmised as the research and implementation of imaging technology, such as x-ray devices and radiation in diagnostic and applicable uses to treat an array of maladies. Ultrasounds, nuclear medicine, PETs (positron emission tomography), MRIs (Magnetic resonance imaging), and computed tomography are a few of the technologies used.
Wikipedia’s Definitions of aforesaid technologies:
Projection Radiology: Projectional radiography or plain film radiography is the method of making 2-D images with x-ray radiation.
Fluoroscopy: Fluoroscopy is an imaging method commonly used by physicians to get actual-time moving images of the interior structure of a patient with the use of a fluoroscope.
Computer Tomography (C T)/ Computer Axiated Tomography (CAT) : CT or CAT scans are special x-ray tests that produce cross-sectional images of the body using x-rays and a computer.
Ultrasound: Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. The most well known application of ultrasound is its use in sonography to produce pictures of fetuses in the human womb.
MRI: Magnetic resonance imaging (MRI), or nuclear magnetic resonance imaging (NMRI), is primarily a medical imaging technique most commonly used in radiology to visualize detailed internal structure and limited function of the body. It is especially helpful when used to monitor and diagnose neurological disorders.
Nuclear Medicine: In nuclear medicine imaging, radiopharmaceuticals are taken internally, for example intravenously or orally. Then, external detectors (gamma cameras) capture and form images from the radiation emitted by the radiopharmaceuticals.
One practice used in the field of radiology is Teleradiology. Teleradiology is where the results of various methods listed above are sent to a radiologist at a different location, usually during that radiologists office hours. It is advantageously effective when applied to rural or underserved clinics and hospitals, where a radiologist might not be available at the time or at all, and nights and weekends.
Radiology currently is a very competitive medical specialty. A radiologist goes through a minimum of thirteen years of post-secondary education. The breakdown of that amount of time is as follows. Four years are spent obtaining a bachelors degree, usually in pre-medicine or biology. After that, the student must complete either of two medical degrees: Doctorate of Osteopathy (D. O.) or Doctorate of Allopathic Medicine (M. D.) medicine. There aren’t many practical differences between these two certifications besides varying intensities of focus areas, but nonetheless they are regarded as equivalent certifications. This training takes approximately four years. After an M. D. or D. O. is received, an Internal Medicine or Surgery specialization may be beneficial, and required by some schools, which could add 3-7 years, depending on the pre-specialty. The radiology specialization itself takes roughly 5 years to complete. Cumulatively, a radiologist could be in post-secondary school for up to 20 years.
Radiology & How Its Changing
Radiology was once one of the most sought after and competitively salaried specialties in the medical field. Today however, due to healthcare reform, population ages shifting, and employment market saturations and deficits, radiologists are on unsteady ground. The worst case scenario is that Radiology demand will stay high and steady, but salaries will fall. This seems to be what’s happening now, but the circumstances surrounding it are too volatile to make any definitive predictions.
