| Question | Answer |
|---|---|
| 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 |
| This diagnostic study uses a magnetic field and radio waves to produce sagittal, coronal and axial images of the body. | magnetic resonance imaging |
| Angio | angiography |
| AP | anteroposterior |
| CT | computed tomography |
| CXR | chest x-ray (film) |
| Decub | decubitus |
| DI | diagnostic imaging |
| DSA | digital substraction angiography |
| Gd | gadolinium |
| IVP | intravenous pyelogram |
| KUB | kidneys, ureters and bladder |
| LAT | lateral |
| L-spine | lumbar spine film |
| MR, MRI | magnetic resonance imaging |
| MRA | magnetic resonance angiography |
| PA | posteroanterior |
| PET | positron emission tomography |
| RFA | radiofrequency ablation |
| SBFT | small bowel follow through |
| SPECT | single photon emission computed tomography |
| UGI | upper gastrointestinal (series) |
| US, U/S | ultrasound, ultrasonography |
| V/Q scan | ventilation and perfusion scan of the lungs |
