Final answer:
A noninvasive procedure for examining the kidneys is the magnetic resonance imaging (MRI), which provides detailed images without radiation exposure.
Step-by-step explanation:
The type of test that is a noninvasive procedure and can examine the kidneys to detect abnormalities or clarify findings from other tests such as magnetic resonance imaging (MRI). An MRI is a medical imaging technique that does not expose patients to radiation, and is particularly useful for precise imaging to discover tumors or other soft tissue abnormalities. It is based on the nuclear magnetic resonance (NMR) phenomenon, where a strong magnetic field interacts with the nuclei of certain atoms, especially hydrogen, to produce detailed images of the structure and function of organs, including the kidneys.
