This study was designed to evaluate the usefulness of 18-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) colonography in preoperative diagnosis tumors proximal obstructive colorectal cancers, which were defined as cancers that cannot be traversed colonoscopically.A whole-body PET/CT protocol for tumor staging and a CT integrated into one examination. No cathartic bowel preparation used before this Thirteen prospective patients with cancer examined. We compared detection rates obstruction using air-inflated intraoperative examinations, histopathologic outcome, follow-up colonoscopy.PET/CT correctly identified all 13 primary 2 synchronous colon obstruction. The two detected at confirmed removed single-stage surgical procedures. able localize precisely. There no false-negative or false-positive by colonography. Other examinations missed cancers.In provided valuable anatomic functional information entire properly address surgery cancer.
