简要总结
The aim of this study is to evaluate the performance of dual-energy CT (DECT) in the diagnosis of acute bowel ischemia (ABI). ABI is a condition characterised by inadequate blood supply to portions of the intestine. ABI is a relatively rare condition, but is associated with a high mortality rate.
DECT is an emerging field within radiology. Few reports have reported an increased conspicuity for ABI using DECT compared with conventional CT, which is the current preoperative golden standard.
The investigators hypothesize that DECT increases conspicuity of ABI compared with conventional CT and that DECT image findings correlate with the intraoperative findings.
