Final answer:
The test is a renal nuclear scan, which utilizes radiopharmaceuticals to evaluate kidney structure and function as well as blood flow after IV injection of a radioactive tracer.
Step-by-step explanation:
The test used to evaluate blood flow, structure, and function of the kidneys after IV injection of a radioactive tracer is called a renal nuclear scan. This imaging technique involves the use of radiopharmaceuticals that are traced within the body to reveal metabolic and physiological functions in tissues, including the kidneys. A renal nuclear scan is a type of nuclear medicine imaging that provides detailed pictures of the kidneys, helping to assess their function and structure.
Renal function tests are a set of various individual tests and procedures used to evaluate the state of the kidney and its role in renal physiology. The glomerular filtration rate (GFR) is one important measure of kidney excretory function and can be estimated with tests like the creatinine clearance. A renal nuclear scan is different from other tests like X-rays or CT scans, as it specifically looks at the function and flow within the kidneys rather than just their structure.
