Indium-111 (In-111) emits which of the following energy levels?

Indium-111 (In-111) is a radioisotope commonly used in nuclear medicine, particularly for imaging procedures. The primary emission of In-111 involves gamma radiation, which is crucial for diagnostic imaging.

In-111 specifically emits gamma photons at energy levels of approximately 171 keV and 245 keV. These energies are significant because they fall within the range that is suitable for detection by gamma cameras, making In-111 an effective radiotracer for various diagnostic applications. The combination of these two emission levels allows for enhanced imaging quality and accurate localization of radiopharmaceuticals in the body, which is important for identifying abnormalities in different tissues.

Understanding these energy levels helps healthcare professionals select appropriate imaging agents and interpret the results effectively, ultimately contributing to better patient diagnosis and treatment planning.
