Answer

Ultrasonography is the most widely used imaging technique to help diagnose ADPKD. [33] It can detect cysts from 1-1.5 cm. This study avoids the use of radiation or contrast material, is widely available, and is inexpensive. The sensitivity of ultrasonography for ADPKD1 is 99% for at-risk patients older than 20 years; however, false-negative results are more common in younger patients. Sensitivity for ADPKD2 is lower and is still not well defined.
