Question

use the drop-down menus to complete the passage. some forms of elements are isotopic and can decay. we make use of these by using them in ways to help image tissue or to treat it. we can couple a radioisotope to an element or compound to localize at certain tissues in question, to help image it by detecting the molecule; this is known as a(n). when the same type of technique is applied but the purpose is to target something like a tumor and treat it with the radiation produced, we call this substance a. nuclear medicine, whether used in diagnosis or to treat, involves the use of, so the amount of that is received by the patient should be considered.

Explanation:

To solve this, we analyze each blank based on nuclear medicine and radioisotope concepts:

First Blank:

The sentence refers to using isotopic (radioactive) forms of elements. The term for these is radioisotopes (since they decay and are used in imaging/treatment).

Second Blank:

When a radioisotope is coupled to a molecule to image tissue (diagnostic use), this is a radiotracer (or "tracer")—it traces the molecule’s location.

Third Blank:

For treatment (e.g., targeting tumors), the substance is a radiopharmaceutical (specifically for therapy, sometimes called a therapeutic radiopharmaceutical, but "radiopharmaceutical" fits for treatment-focused use here).

Fourth Blank:

Nuclear medicine uses radiation (from radioisotopes) for diagnosis/treatment.

Fifth Blank:

The amount of radiation (or "dose") received by the patient must be considered (due to radiation safety).

Filled Passage:

Some forms of elements are isotopic and can decay. We make use of these $\boldsymbol{\text{radioisotopes}}$ by using them in ways to help image tissue or to treat it. We can couple a radioisotope to an element or compound to localize at certain tissues in question, to help image it by detecting the molecule; this is known as a(n) $\boldsymbol{\text{radiotracer}}$. When the same type of technique is applied but the purpose is to target something like a tumor and treat it with the radiation produced, we call this substance a $\boldsymbol{\text{radiopharmaceutical}}$. Nuclear medicine, whether used in diagnosis or to treat, involves the use of $\boldsymbol{\text{radiation}}$, so the amount of $\boldsymbol{\text{radiation (or dose)}}$ that is received by the patient should be considered.

(Note: Exact drop - down options may vary, but these terms align with nuclear medicine terminology. For example, the first blank could also be "properties" in some contexts, but "radioisotopes" is more precise. The key is matching the terminology to the concepts of radioisotope use in imaging (tracer) and treatment (radiopharmaceutical), with radiation as the energy involved and dose/radiation as the quantity to monitor.)
