Abstract
This study was undertaken to determine the incidence of low attenuation values in intraperitoneal hemorrhage, which could be confused with ascites. We retrospectively analyzed the CT scans of 42 consecutive patients with hepatic and splenic lacerations and intraperitoneal fluid after blunt abdominal trauma. Patients were excluded if they had prior peritoneal lavage, bladder or bowel injury, or low hematocrit values. Intraperitoneal fluid was categorized by the site of accumulation (perihepatic, perisplenic, Morison's pouch, paracolic gutters, or pelvis). The amount of fluid in each intraperitoneal location was categorized as small, moderate, or large. Attenuation values were obtained from each intraperitoneal site, and overall mean attenuation values were determined for each patient. We correlated the size of each fluid collection with the attenuation value. We also compared attenuation values at locations adjacent to the site of each injury with those at other intraperitoneal sites. We then evaluated technical factors that could have lowered attenuation values, including CT miscalibration, volume averaging, and beam-hardening artifacts. For the 42 patients, we measured 131 separate attenuation values. Attenuation values ranged...Continue Reading
