Temporal resolution is related to which of the following acquisition parameters?

• A. Spatial resolution
• B. Framing rate
• C. Energy resolution
• D. Detector sensitivity

Answer: (B)

Temporal resolution refers to the ability of a nuclear medicine imaging system to accurately capture changes over time. This is especially important in dynamic studies where the motion of a radiopharmaceutical within the body is being measured. The framing rate, which determines how frequently images are captured over time, directly influences temporal resolution. A higher framing rate allows for more frequent snapshots of the process, enabling finer temporal detail and the capability to observe rapid physiological changes. In contrast, spatial resolution relates to the ability of the imaging system to distinguish between two closely spaced objects in space, energy resolution pertains to the system's ability to distinguish between different energy levels of detected photons, and detector sensitivity refers to the likelihood of a detector responding to incoming radiation. While all these factors are crucial for the overall performance of a nuclear medicine imaging system, it is the framing rate that specifically governs temporal resolution.
