Select the answer that best describes how B-mode will typically display blood vessels?

  1. Anechoic

  2. Heterogeneous

  3. Hyperechoic

  4. Isogenic

The correct answer is: Hyperechoic

B-mode typically displays blood vessels as hyperechoic. This is because blood vessels appear bright on ultrasound imaging due to the reflection of the ultrasound waves by the vessel walls. This brightness or hyperechoic appearance differentiates blood vessels from the surrounding tissues. In comparison: - Anechoic structures appear black on ultrasound with no echoes returning. - Heterogeneous structures have mixed echogenicity with varying shades of gray. - Isogenic is not a standard term in ultrasound imaging.
