Clinical Application of MSCT Dynamic Enhancement and Image post-processing in Preoperative Imaging Evaluation of Gastrointestinal Neoplastic Lesions
Objective To evaluate the clinical application value of MSCT dynamic enhancement and image post-processing in the preoperative treatment of gastrointestinal tumors.Methods CT images of 31 cases of gastrointestinal tumors with complete data were retrospectively analyzed.Results There were 24 cases with different degree of gastrointestinal thickening,and 10 cases with thickening degree exceeding 3cm.Intestinal stenosis occurred in 12 cases,of which 2 cases had intestinal obstruction.There were 4 cases with soft tissue mass protruding into or out of the lumen,uniform and moderate enhancement.2 cases of mass formation showed uneven enhancement;Fat density thickened and fascia shadow thickened in 22 cases.Lymph node metastasis in 14 cases;Distant organ metastasis occurred in 4 cases.Conclusion Multi-stage dynamic enhancement of MSCT,combined with image post-processing technology,can accurately evaluate tumor resectability,peripheral invasion,blood supply progression,peritoneal dissemination and distant organ metastasis.Preoperative imaging evaluation has high clinical application value for gastrointestinal tumors treated by surgical resection.
