Which of the following is NOT required to calculate standardized uptake value (SUV)?

To calculate the standardized uptake value (SUV), certain parameters need to be taken into account to ensure accurate quantification of radiotracer uptake in tissues. The correct answer indicates that patient age is not a required factor in this calculation.

SUV is determined by the formula:

[ \text{SUV} = \frac{\text{Tissue Activity Concentration} (\text{Bq/ml})}{\text{Injected Dose} (\text{Bq}) / \text{Body Weight} (\text{kg})} ]

From this formula, it's apparent that the calculation involves the tissue activity concentration, the injected dose, and the patient's body weight. Thus, patient weight is essential for normalizing the tissue activity concentration to a common denominator, and the injected dose is necessary for assessing the amount of radiotracer administered to the patient.

While height might impact factors such as metabolic rate and distribution volumes in certain contexts, it is not a direct component of the SUV calculation itself. However, age does not factor into this formula or affect the calculation directly; it merely provides context about the patient but does not influence the SUV metric itself. Therefore, patient age is the correct answer as it is not required when calculating SUV.
