Advances of low-dose multi-slice spiral CT colonography in colorectal diseases

Low-dose multi-slice spiral CT colonography plays an important role in the early inspection of colorectal diseases. Compared with traditional CT colonography, traditional colonoscopy, fecal occult blood test and double contrast barium enema examination, low-dose multi-slice spiral CT colonography has advantages in low radiation, simple operation, well compliance and higher disease detection rates, accuracy and sensitivity. Low-dose multi-slice spiral CT colonography can also increase the detection rates of early colorectal tumors, so as to prolong the survival period, improve the quality of life. It has a high application value in the diagnosis and treatment of colorectal tumors. (authors)
