Effectiveness of magnetic resonance imaging and spiral computed tomography in the staging and treatment prognosis of colorectal cancer

Figure 1 Imaging images. A: Sagittal image; B: Cross-sectional image. The orange arrows show that the lower rectal wall of the patient was thickened, and obvious changes were observed after enhancement. Small lymph nodes were seen around the lesion. The sample images were from the digital medical record database.
