Sample item

How does simple fluid usually appear on diagnostic ultrasound?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Anechoic with posterior acoustic enhancement

Simple fluid transmits sound with few internal echoes, appearing anechoic and often causing posterior acoustic enhancement; this helps distinguish cystic from many solid structures.

Option by option

  • A. Brightly echogenic with dense shadowing

    Dense calcification is more likely to be bright with shadowing.

  • B. Anechoic with posterior acoustic enhancement (correct)

    Correct: simple fluid is usually dark and enhances sound transmission behind it.

  • C. Always invisible

    Fluid is commonly visible on ultrasound when accessible.

  • D. As a metallic artifact only

    Metal produces artifacts but is not the normal appearance of fluid.
