Abstract
[Purpose] The aim of this study was to evaluate the diagnostic ability of Multidetector Computed Tomography (MDCT) for lower gastrointestinal diverticular hemorrhage. [Materials and Methods] Three radiologists reviewed MDCT findings in 12 cases and investigated the relationship between imaging findings and the patients’ blood pressure, volume of transfusion, and treatments applied. [Results] MDCT examination demonstrated “extravasation” in 7 cases, and luminal abnormalities, i.e., “high density area with bubble”, “fluid collection” and “clot” in 5, 8, and 4 cases, respectively. Four of six cases who required blood transfusion demonstrated extravasation. The systolic blood pressure of three cases with extravasation was below 95 mmHg. [Conclusion] Extravasation on MDCT which was frequently observed in patients with hypotension and/or requiring blood transfusion, was highly specific for diagnosing the bleeding site. MDCT was also useful for procedural planning in IVR, endoscopic and surgical management.
