Radiology Vocab Flashcards
CT -Computed Tomography
Diagnostic X-ray procedure where by a cross-sectional image of a specific body segment is produced. Newer CT scanners can create 3D images as well
Contrast studies
radiopaque materials (contrast media) are injected to obtain contrast between tissues that would be indistinguishable from one another.
Gamma Camera
Machine to detect gamma rays emitted from radiopharmaceuticals during scanning for diagnostic purposes
Gamma Rays
High-energy rays emiited by radioactive substances used in tracer studies
Half life
Times required for a radioactive substances to lose half its radioactivity by disintegration
interventional radiology
Therapeutic or diagnostic procedures performed by a radiologist. ex. needle biopsy of a mass and drainage of abscess normally under the guidance of a CT, ultrasound, or fluoroscopy
in vitro
process, test , or procedure is performed, measured, or observed outside a living organism, often in a test tube
in vino
process, test , or procedure is performed, measured, or observed outside a living organism.
ionization
Transformation of electrivcally neutral substances into electrically charged particles. X-rays cause ionization of particles within tissues
MRI Magnetic Resonance Imaging
Radiosotope
Nuclear Medicine
Positron Emission Tomography (PET)
Radioimmunoassay
Radiolabeled Compound
