Radiology Flashcards
Anatomic Position
Erect, facing forward, arms rotated outward with the palms forward, hands open with thumbs pointed out. The feet are together or slightly apart
Supine Position
Lying down on the back with the face up. This position is also known as dorsal recumbent (lying down)
Prone position
Lying face down on the front of the body. This position is also known as ventral recumbent
Lateral Position
Position in which the side of the subject is next to the film. This can be performed as erect lateral (standing side) or lateral decubitus (lying down side)
Oblique Position
Slanted position where the patient is lying at an angle neither prone nor supine. In radiology you may see right anterior oblique (RAO), left anterior oblique (LAO), Right posterior oblique (RPO), or left posterior oblique (LPO). The anterior or posterior terminology indicates the part of the body closer to the film. For example, in RAO, a person is on his right side with the anterior part of the body closer to the film.
Angiography
Radiographic image of the blood vessels using contrast material
Aortagraphy
Radiographic image of the aorta and branches using contrast material
Atherectomy
To remove plaque from an artery
Brachytherapy
Radiation placed in or near a tumor within the body. Catheters, needles, seed or wires may be used
Bronchography
Radiographic image of the bronchi of the lungs, using contrast material
Cephalogram
Radiographic image of the head
Cholangiography
Radiographic image of the bile duct
Cineradiography
Radiography of an organ in motion (for example a beating heart)
Colonography
Radiographic image of the (interior) colon
Computed Tomography (CT)
Using specialized equipment, two dimensional X-ray images are taken around a single axis of rotation. The images are combined to create a three dimensional image or picture of the inside of the body. These cross sectional images of the area being studied may be examined on a computer monitor, printed or transferred to a CD.
Cystography
Radiographic image of the bladder
Dacyocystography
Radiographic image of the lacrimal draining system
Discography
Radiographic image of the disc of the spine
Doppler
A type of ultrasound, especially useful for imaging blood flow. The Doppler can create images either in shades of gray or when processed by a computer in color
Dual Energy X-ray Absorptiometry (DEXA/DXA)
Test performed to determine bone density
Ductogram
Imaging of the ducts in the breast
Duodenography
Radiographic examination of the duodenum and pancreas
Echocardiography
Imaging using sound waves to create a moving picture of the heart
Echoencephalography
Ultrasound image of the brain
Epidurography
Imaging of the epidural space in the spine
Fluoroscopy
A continuous X-ray image used to view the movement of the body part, or of an instrument or a dye moving through the body
Hyperthermia
A type of cancer treatment in which tissue is exposed to high temperatures (up to 113 degrees F)
Hysterosalpingography
Fluoroscopic imaging (with contrast of the uterus and fallopian tubes)
Intraluminal
Within the lumen
Laryngography
Radiographic image of the larynx
Lymphangiography
Diagnostic imaging to view lymphatic circulation and lymph nodes; utilizes x-ray technology and the injection of a contrast agent
Magnetic Resonance
Magnetic fields align the protons within the body to produce image slices, which are combines to produce 3-D images, may be viewed from different angles performed wither with or without contrast.
Myelography
Radiographic image of the spinal cord
Nephrotomography
CT image of the kidneys
Orthopantogram
Panoramic, radiographic image of the entire dentition, alveolar bone, and other adjacent structures on a single film; taken extra-orally
Pachymetry
Measurement of corneal thickness
Pancreatography
Radiographic image of the pancreatic ducts following injection of radiopaque material
Pelvimetry
Measurement of the dimension and capacity of the pelvis
Position Emission Computed Tomography (PET)
Nuclear imagining assessing the level of metabolic activity and perfusion in various organ systems of the body
Protography
X-ray visualization of the portal circulation using radiopaque material
Pyelography
Radiographic imaging of the renal pelvis of a kidney following injection of a radiopaque substance through the ureter or into a vein
Shuntogram
Placement of a radioactive isotope in the shunt reservoir in the head to measure the speed with which it moves to the abdomen. Shuntogram is the term used for angiography of an A/V fistula for renal dialysis
Sialography
Radiographic image of the salivary ducts and glands
Single Photon Emission Computed Tomography (SPECT)
Nuclear imaging using radioactive tracers to show how blood flows to organs and tissues
Sonohysterography
Ultrasound imaging of the uterus
Splenoportography
Radiography of the splenic and portal veins, which includes injection of a radiopaque medium
Teletherapy
Any treatment where the source of the therapeutic agent (for example radiation) is at a distance from the body; delivery of radiation to a tumor from and external beam source as compared to implantation of radioactive material or systematic administration of radionuclide
Transcatheter
Performed via the lumen of a catheter
Ultrasound
High frequency sound waves are used to produce two dimensional images in examining structures inside the body or for detecting abnormalities
Urethrocystography
Radiography of the urethra and bladder using a radiopaque substance
Urography
Imaging of the kidney, ureters, or bladder
Vasography
Radiographic image of the vas deferens and ejaculatory duct following dye injection
Velocity Flow Mapping
A noninvasive method to image blood flow through the heart by displaying flow data on the two dimensional echocardiographic image
Venography
A radiographic image of the veins following injection of contrast dye
Xeroradiography
Creation of radiographs by photoelectric process, using metal plates coated with semiconductor (for example, selenium)
