Anatomic and functional evaluations of the kidneys are classified as

• A. Cardiac NM Studies
• B. Genitourinary Studies
• C. Lung NM Studies
• D. Thyroid Uptake Study

Answer: (B)

Kidney evaluations, whether looking at anatomy or function, fall under genitourinary studies. This category covers imaging and tests of the kidneys and urinary tract, including structural assessments and functional measurements like renal perfusion, filtration, and excretion. In nuclear medicine, renography and other renal scans are classic examples of genitourinary evaluation. By contrast, cardiac NM studies assess heart muscle and blood flow, lung NM studies focus on the lungs, and a thyroid uptake study targets thyroid function. So, the kidneys are classified as genitourinary studies.
