Chapter 20- Radiology and Nuclear Medicine

The medical specialty concerned with the study of x-rays is called ____________________. radiology
The medical specialty that studies the characteristics and uses of radioactive substances in the diagnosis of disease is called _______________________. nuclear medicine
A substance that is _________________ permits the passage of most of the x-rays. radiolucent
________________ substances are those that absorb most of the x-rays they are exposed to allowing only a small fraction of the x-rays to reach the x-ray plate. radiopaque
An _________________ is the x-ray image of blood vessels and heart chambers obtained after contrast is injected through a catheter into the appropriate blood vessel of heart chamber. angiography
When contrast or air or both are injected into a joint, and x-ray images of the joint are obtained it is referred to as an _________________________. arthrography
The x-ray image of contrast-injected blood vessels produced by taking two x-ray pictures and using a computer to subtract obscuring shadows from the second image is called __________________________. digital subtraction angiography
An x-ray procedure using an image intensifier instead of a photographic plate to derive a visual image from the x-rays that pass through the patient is called ______________________. fluoroscopy
The use of high-frequency inaudible sound waves that bounce off the body tissues is called _____________________. ultrasound
When x-rays travel from a posteriorly placed source to an anteriorly placed detector it is called a ________________________. posteroanterior view
When x-rays travel in a slanting direction at an angle from the perpendicular plane the technologist is taking an _________________. oblique view
Movement away from the midline of the body abduction
Movement toward the midline of the body. adduction
turning outward eversion
Lengthening or straightening a flexed limb. extension
bending a part of the body. flexion
turning inward inversion
lying down on the side with the x-ray beam horizontally positioned lateral decubitus
lying on the belly prone
lying on the back supine
The two types of tests used by nuclear medicine physicians to diagnose disease are called . in vitro and in vivo
This radionuclide technique produces images of the distribution of radioactivity through the emission of positrons in a region of the body. PET scan
This technique involves an IV injection of a radioactive tracer and the computer reconstruction of a 3D image based on a composite of many views. SPECT scan
This nuclear medicine study is utilized to evaluate myocardial perfusion. thallium scan
A diagnostic x-ray procedure whereby cross-sectional image of a specific body segment is produced. computed tomography
