Question

Quizplus · Accepted Answer

Computed tomography (CT) provides the greatest imaging sensitivity in detecting nephrolithiasis compared to the other modalities listed. CT can detect stones as small as 1-2 mm and provide detailed information on the size, location, and number of stones. Plain film radiographs and intravenous pyelography have lower sensitivity and are more useful for monitoring stone progression. Diagnostic ultrasonography is less sensitive than CT but can be useful in certain cases, such as in pregnant patients or those with allergies to contrast agents.
