title: MDCT of acute lower gastrointestinal bleeding.
abstract: OBJECTIVE
  We evaluated the use of MDCT in the diagnosis and management of lower gastrointestinal bleeding (hematochezia).
  
  
  CONCLUSIONS
  MDCT is proposed as an alternative first-line investigation to locate lower gastrointestinal bleeding before placing the patient under observation or performing embolization or surgery.
