Time-Intensity Curve Parameters in Rectal Cancer Measured Using Endorectal Ultrasonography with Sterile Coupling Gels Filling the Rectum: Correlations with Tumor Angiogenesis and Clinicopathological Features
Figure 3
Images of moderately differentiated rectal adenocarcinoma with T3 stage. (a) Endorectal ultrasonography showed an irregular hypoechoic lesion proceeded beyond the muscularis propria and serosa and perirectal fat. (b) Time-intensity curve was obtained from ROI with EI = 29.61 dB, AT = 5.83 s, TTP = 10.49 s, WIT = 4.66 s, and AS = 6.35. (c) Representative photomicrographs of Immunohistochemical CD34 staining in the same tumor (200x magnification) showed microvasculature in brown and moderately differentiated rectal adenocarcinoma. The MVD value is 24.
