Diagnostic Value of Multi-slice Spiral CT in Calcified Liver Metastases of Colorectal Cancer
This paperanalyse the diagnostic value of multi-slice spiral CT in calcifying metastases of liver of colorectal cancer. All patients underwent multi-slice spiral CT examination. All the 30 patients were proved to be non-mucinous adenocarcinoma by operation and pathology. There were 5 poorly differentiated patients, 25 moderately differentiated patients, 13 right hemicolon patients and 17 left hemicolon patients. There were 4 cases of calcified metastasis in pelvis and 3 cases of diffuse calcified metastasis in lung. There are three main types of calcification in metastatic tumors. Among them, the incidence of fine granular or gravel-like is the highest, the proportion of central distribution is the highest, and the incidence of petal-like enhancement is the highest in CT enhancement. Compared with other types, the difference of data is significant (P < 0.05). The distribution of metastatic tumors in right and left lobes of patients with right hemicolon is quite different, which is easy to transfer to the right lobe of liver. The difference of data is significant (P < 0.05). The calcification rate of metastatic tumors in left and right hemicolon cancer is significant (P < 0.05). Relatively, the difference of data is prominent, and the comparison result is significant (P < 0.05). A total of 250 metastatic tumors were detected in 30 patients, of which 95 were calcified. The total calcification rate of metastatic tumors was 38.00%. The calcification rate of metastatic tumors in the right and left lobes of the liver was significantly different (P < 0.05). Multi-slice spiral CT has significant diagnostic value for liver calcification metastasis of colorectal cancer. It can accurately judge the diagnosis of colorectal cancer liver calcification metastasis disease, and has less impact on patients' radiation and can accurately display The type and severity of disease calcification in patients is worthy of promotion in the clinic.
