Question

1. Use your knowledge of Medical Terminology to best answer the questions:

1. What is the medical specialty that studies the characteristics and uses of radioactive substances in diagnosis of disease?      
2. What is a Myelogram?      
3. What is the medical term for an x-ray of a joint?      
4. In which x-ray view is the patient upright with the back to the x-ray machine and the film to the chest?      
5. What is the meaning of adduction?      
6. In which procedure is a transducer used?      
7. Technique using a radioactive substance and a computer to create three-dimensional images is called a     . (note the acronym AND list what it stands for)

2. Matching terms with meanings (re-type the terms to match with meanings below)

Match the following terms with their meanings below:
computed tomography (CT)	gamma rays	ionization
contrast studies	half-life	magnetic resonance (MR)
gamma camera	interventional radiology	nuclear medicine
positron emission tomography (PET)	radioimmunoassay	radioisotope
radiopaque	radiopharmaceutical	scan
scintigraphy	tagging	ventilation-perfusion studies

1. Therapeutic procedures performed by a radiologist      
2. Transformation of electrically neutral substances into electrically charged particles      
3. Diagnostic x-ray procedure whereby a cross-sectional and other images of a specific body segment are produced      
4. Materials are injected to obtain contrast with surrounding tissue when shown on x-ray film      
5. Radioactive substance is given intravenously, and a cross-sectional image is created of cellular metabolism based on local concentration of the radioactive substance      
6. Magnetic field and radio waves produce images of the body in three planes (coronal, sagittal, and axial)      
7. Test that combines radioactive chemicals and antibodies to detect minute quantities of substances in a patient’s blood      
8. Image of an area, organ, or tissue obtained from ultrasound, radioactive tracer studies, computed tomography, or magnetic resonance imaging      
9. Obstructing the passage of x-rays      
10. Diagnostic nuclear medicine test using radiopharmaceuticals and gamma cameras to create images      

Answer 1

Answer A: Nuclear Medicine is the medical specialty that studies the characteristics and uses of radioactive substances in diagnosis of disease.

Myelogram is a test which is performed with the help of the radiographic examination. In this the contrast medium is used to identify the injury, cyst or the tumors in the spinal cord.

Arthrograpy is the medical term for an x-ray of a joint.

In the PA view (posteroanterior) the patient upright with the back to the x-ray machine and the film to the chest.
