Application of 256 slice spiral CT in malignant tumor of colorectal obstruction / 中国医师杂志

ABSTRACT

Objective To explore the application value of 256 slice helical multi phase CT scan-ning and three-dimensional reconstruction in the diagnosis of malignant tumor of colorectal obstruction. Methods Using 256 slice spiral CT scanning and three-dimensional reconstruction of multi period in 42 ca-ses of malignant tumor patients with colorectal obstruction, the results and pathological results were analyzed and the postoperative stage.Results Forty-two cases of malignant tumors of colorectal obstruction, 256 slice spiral CT could well reflect the situation of location, range, degree, peripheral intestinal lymph node and distant metastasis, CTA could show the tumor supplying artery and branch sources, on the tumor loca-tion and overall accuracy.Conclusions 256 layer spiral CT scan and three dimensional reconstruction technology is accuracy for clinical diagnosis on malignant tumor of colorectal obstruction.
