Final answer:
A CT urogram study evaluates the kidneys, ureters, and bladder. It collects images during the nephrogenic phase and requires the patient to drink 2 quarts of water within 45 minutes.
Step-by-step explanation:
A CT urogram study evaluates several structures related to the urinary system, including the kidneys, ureters, and bladder. It collects images during the nephrogenic phase, which begins 30 seconds after the start of the IV contrast injection. In order to prepare for the exam, the patient is required to consume 2 quarts of water within 45 minutes. This helps to ensure proper visualization of the urinary system during the study.
