Med Term- Radiology & Nuclear Medicine

Which of the following is NOT a characteristic of an x-ray?

• velocity

• wavelength

• ionization

• weight

Which of the following characteristics of x-rays is most damaging to a fetus?

• velocity

• radiation

• wavelength

• ionization

What is a tracer?

• a red line that appears on the scan

• a radioactive agent

• a plastic object you swallow for the test

• a record produced by the test

A tracer is used in which type of imaging?

• ultrasound

• MRI

• scintigraphy

• radiation

This type of radioactive positron that is used to detect thyroid disorders:

• glucose

• iodine

• thallium

• technecium

The production of "slice" views of body structures used with scintigraphy:

• SPECT

• PET

• FDG

• IR

Of all the types of x-ray therapy, this one has the greatest incidence of radiation being applied to normal, healthy tissue:

• proton beam therapy

• conventional external-beam radiation therapy

• intensity-modulated radiation therapy

• stereotactic radiation

This therapy can treat cancer with high doses of radiation without adjacent normal tissue damage:

• proton beam therapy

• conventional external-beam radiation therapy

• intensity-modulation radiation therapy

• stereotactic radiation

Which x-ray characteristic is electromagnetic?

• speed

• velocity

• wavelength

• ionization

What is real-time imaging?

• You take pictures during a scan and view them later

• You see images in a screen as the scan is actually happening

• You take pictures before any tracer is administered

• You can only take pictures in the morning
