Question 23 • Physics

Why is the choice of a radiopharmaceutical important in radioisotope imaging?

Answer
A
The radiopharmaceutical must be able to block X-rays to create the image.
B
The radiopharmaceutical must localize to the specific organ or tissue to be imaged.
C
The radiopharmaceutical must pass through the body without being absorbed.
D
The radiopharmaceutical must absorb and re-emit a specific radiation within a magnetic field.

Explanation

A radiopharmaceutical is selected because it travels to or is taken up by the organ or tissue being studied. Its radioactive emissions can then be detected to show where that substance has localized. The correct choice is “The radiopharmaceutical must localize to the specific organ or tissue to be imaged.”
