Radiography is the making of records of internal structures of the body by passage of x-
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$


rays or gamma rays through the body. These records or images are typically referred to a

2. Particular care must be taken when using radiation for medical imaging. This is the result

c. sound waves d$


d. thermal changes d$




ANS: A d$d$


Some forms of electromagnetic energy, including x-
d$ d$ d$ d$ d$ d$


rays, have the ability to ionize atoms in matter. These ionizations have the ability to disru
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$


pt the composition of matter and are capable of disrupting life processes. Special protecti
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$


on should be provided to prevent excessive exposure to ionizing radiation.

3. In the diagnosis of patient disease states, physicians can select from an array of medical
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$


diagnostic modalities. A few of these involve the use of ionizing energy to create a medi

cal image. If a physician is concerned about the use of ionizing radiation, he or she may

choose to order any of the following diagnostic modalities EXCEPT

ANS: C d$d$


Radiography involves the use of x- d$ d$ d$ d$ d$


rays for the production of medical images. Medical procedures such as thermograms, sono
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$


grams, and magnetic resonance scans use nonionizing energy forms and consequently do
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$


not produce ionizations in human tissue. They are regarded as nonionizing modalities for i

Although the Human Genome Project is finished, analyses of the data will continue for
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$


many years. The replacement of faulty genes through gene therapy offers promises of cure
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$


s for a variety of hereditary diseases, and through genetic engineering, important pharma
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$

6. Wilhelm C. Roentgen’s discovery of “the x-
d$ d$ d$ d$ d$ d$


ray” is regarded as one of medicine’s most significant achievements. Although his disco
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$


very was accidental, his early research was so thorough that no significant findings have
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d


$been added to his original theories. This in itself is a true tribute to the brilliance of Ro
d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$ d$


entgen as a scientist. One of the most famous early images he created was an x-

ray image of his

d. kidneys.
