• ionizations

• radio waves

• thermal changes

In the diagnosis of patient disease states, physicians can select from an array of medical diagnostic modalities. Some of these involve the use of ionizing energy to create a medical 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

• radiography.

• thermograms.

• medical sonography.

• magnetic resonance imaging.

The Greek physician Hippocrates is regarded as the father of Western medicine. All of the following choices represent his medical beliefs except the

• important medical value of sorcery and witchcraft.

• use of high ethical standards of conduct.

• importance of closely monitoring a patient’s condition and recovery.

• value of diet and exercise and allowing nature to take its course in recovery.

Throughout the history of medicine, remarkable achievements have been recorded. These events have led to our current understanding of the human organism and disease. As this research continues, much of it will most likely focus on

• germ theory and infection.

• proper sanitation and public health.

• immunology and the development of vaccines.

• human genes and genetic engineering.

Wilhelm C. Roentgen’s discovery of “the X-ray” is regarded as one of medicine’s most significant achievements. Although his discovery was accidental, his early research was so thorough that no significant findings have been added to his original theories. This in itself is a true tribute to the brilliance of Roentgen as a scientist. One of the most famous early images he created was an X-ray image of his

• colon.

• laboratory assistant’s foot.

• wife’s hand.

• kidneys.

Radiologic science continues to be one of the most exciting professions in medicine. An imaging modality that uses no ionizing radiation and the energy of radio waves and magnetic fields is

• CVIT.

• nuclear imaging.

• thermography.

• MRI

A physician who specializes in the interpretation of medical images is known as a

• radiographer.

• radiologist.

• radiologic technologist.

• radiologist assistant.

The distinction between a technologist and a technician can be confusing to the general public, when related to medical personnel. A key difference between the two involves education. A technologist typically

• has a higher level of education and deal with higher-level problems.

• is very attentive to details as prescribed by a superior.

• works under the supervision of another health care provider.

• works in a supportive role at the direction of a technician.

Many medical professions have developed “practice standards” to ensure optimum performance of their members. The radiography “practice standards” are developed and maintained by the

• American College of Radiology (ACR).

• American Society of Radiologic Technologists (ASRT).

• American Registry of Radiologic Technologists (ARRT).

• Food and Drug Administration (FDA).
