Question

which term is correct when describing nerves on ultrasound?
hyperechoic
fascicular pattern
compact fibrillar pattern
hypoechoic

Explanation:

• Hyperechoic means high - level echoes. Nerves on ultrasound do not typically have this characteristic.
• Hypoechoic means low - level echoes. Nerves are not generally described as hypoechoic.
• Compact fibrillar pattern is not the correct term for describing nerves on ultrasound.
• Fascicular pattern is the correct term. Nerves on ultrasound have a fascicular (bundle - like) appearance due to their anatomical structure of nerve fascicles.

Answer:

fascicular pattern
