Newer CT scanners can create 3D images as well Contrast studies - correct answer Radiopaque materials (contrast media) are injected to obtain contrast between tissues that would be indistinguishable from one another Gamma camera - correct answer Machine to detect gamma rays emitted from radiopharmaceuiticals during scanning for diagnostic purposes Gamma rays - correct answer High energy rays emitted by radioactive substance to lose half its radioactivity by disintegration Half-life - correct answer Time required for a radioactive substance to lose half its radioactivity by disintegration Interventional radiology - correct answer Therapeutic or diagnostic procedures performed by a radiologist. Examples are needle biopsy of a mass and drainage of an abscess, typically under the guidance of CT, ultrasound, or fluoroscopy In vitro - correct answer Process, test, or procedure is performed, measured, or observed outside a living organism, often in a test tube In vivo - correct answer Process, test or procedure is performed, measured, or observed within a living organism Ionization - correct answer Transformation of electrically neutral substances ino electrically charged particles. X-rays cuase ionization of particles within tissues
