- a diagnostic imaging exam that uses x-rays and computer technology to produce slices of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat and the organs.
- MRI - magnetic resonance imaging
- is a medical imaging technique using magnetic fields, radio waves and a computer to create pictures inside the body.
- Ultrasound
- a diagnostic technique which uses high-frequency sound waves
- Doppler
- an ultrasound method of examing blood vessels. No X-rays are involved.
- Radiography
- an image of budy using X-ray
- Diagnostic radiology
- the methods to determine the source of pathology that includes the use of X-rays. CT scan, MRI scan and ultrasound.
- Radiologist
- a physician specializing in the medical field of radiology
- ALARA - As Low As Reasonably Achievable
- means to protect all the patients, making the exam with the minimum dose
- Dose(radiation)
- radiation absorbed by a person's body
- Lethal dose (50/30)
- the dose of radiation that cause death within 30 days to 50% of exposed people. The generally accepted dose is about 400Rem received over a short period of time.

I'm studying Diagnostic Imaging at Ahuntsic College. This program learn how to produce images of bones and organs inside the human body. We use different technologies such as X-ray radiography, ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) to diagnose diseases. I will explain some terms that we use in Diagostic Imaging.
CT - computed tomography
Radiologic Shield
barrier imposed berween radiation expose and the patient. It can guarantee a 95% reduction of X-ray exposure
Cystography
radiography of the bladders, following by injection of a radiopaque substance
Mammography
examination of the brest using X-rays
