What is the term for a radiographic examination of the contrast-filled bladder?

• A. Urogram
• B. Cystography
• C. Ureterography
• D. Nephrogram

Answer: (B)

The term for a radiographic examination of the contrast-filled bladder is cystography. This procedure involves the introduction of a contrast agent into the bladder, allowing for detailed imaging of its structure and function. Cystography is particularly beneficial for diagnosing conditions such as bladder abnormalities, infections, or trauma.

Urograms refer generally to imaging of the urinary tract, including the kidneys, ureters, and bladder, but do not specifically focus on the bladder alone. Ureterography is used to visualize the ureters, the tubes that carry urine from the kidneys to the bladder, and is not concerned with the bladder itself. Nephrograms are imaging studies specifically aimed at the kidneys. Each of these terms denotes a different aspect of urinary system imaging, with cystography being the precise term for what focuses solely on the bladder.
