Radiology and Nuclear Medicine Final
2024/2025 Exam Questions and Detailed
Answers
Diagnostic imaging - 🧠ANSWER ✔✔Radiology, nuclear med, photography, mico
imaging, and other types
Radiography - 🧠ANSWER ✔✔Most common subspecialty. It uses x-rays to
produce a diagnostic imaging.
X-rays - 🧠ANSWER ✔✔Are a form of invisible radiation. Produced when a
positively charged metal plate inside a vacuum is bombarded with a stream of
electrons.
They have short wavelengths and contain so much energy that they are able to
pass through the body
Radiography (roentgenography) - 🧠ANSWER ✔✔The patient is placed between
the x-ray machine and a large, flat, silver x-ray plate. The beams travel through
the body to the plate.

, Dosimetry - 🧠ANSWER ✔✔process of measuring the amount of radiation
exposure, detected and measured by dosimeter
dos/i - 🧠ANSWER ✔✔dose
Lead apron - 🧠ANSWER ✔✔Lead doesn't let x-rays pass through because it's so
dense. Therefore, lead aprons are used to shield parts of the patients body that
are not being x-rayed; they are also worn by the radiology department if they
are in the room.
plain film - 🧠ANSWER ✔✔any radiograph that is taken without the use of
radiopaque contrast dye
portable film - 🧠ANSWER ✔✔radiograph taken at the patients bedside on the
nursing unit or in the ER department when the patient cannot be transported
scout film - 🧠ANSWER ✔✔preliminary x-ray that is taken to provide an initial
view of an area before a radiopaque contrast dye is administered
x-ray cassette and bucky - 🧠ANSWER ✔✔a cassette is the case that holds the x-
ray film. A bucky is an adjustable frame that is mounted on the wall, beneath
the x-ray table, or is a mobile frame on wheels. It positions and holds the x-ray
cassette
