Dynamic power Doppler ultrasonography of anterior abdominal wall hernias: confirmation of incarceration

Purpose: Power Doppler ultrasonography (PD-US) is a motion-sensitive modality that can display flow characteristics regardless of the direction. This increased motion sensitivity can be used as a parameter to show the tissue motion on artificially generated fremitus images. This study aimed to confirm any signs of incarceration in abdominal wall hernias proven by herniorrhaphy by examination with dynamic PD-US (during manual compression-decompression maneuvers). Methods: Twenty-seven patients with anterior abdominal wall hernia with a narrow neck (
