The clinical data including spiral CT and B-mode ultrasound in 260 patients with colorectal malignant neoplasm diagnosed by colonoscopy and pathological examination were analyzed, retrospectively. The positive rate of colorectal malignant neoplasm by spiral CT (82.3%) was significantly higher than that by B-mode ultrasound (24.7%). The highest ratio detected by B-mode ultrasound was right colon (the ascending and transverse colons), however, that by CT was the ascending and rectum. The accordance, sensitivity and speiciality of metastatic organs detected by CT were 73.2%, 57.7%, 94.7%, respectively; those of metastatic lymph nodes by CT were 85.2%, 23.7%, 97.6%, respectively. The accordance, sensitivity and speiciality of metastatic organs detected by B-mode ultrasound were 72.2%, 35.1%, 96.6% Respectively; those of metastatic lymph nodes by B-mode ultrasound were 63.6%, 10.5%, 96.6% Respectively. Spiral CT scan and B-mode ultrasound examination have an important value for the diagnosis and staging of colorectal malignant neoplasm.
