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 2
Images of poorly differentiated rectal adenocarcinoma with T2 stage. (a) Endorectal ultrasonography showed that an irregular hypoechoic lesion invaded muscularis propria. (b) Time-intensity curve was obtained from ROI with EI = 36.83 dB, AT = 6.87 s, TTP = 14.57 s, WIT = 7.70 s, and AS = 4.78. (c) Representative photomicrographs of Immunohistochemical CD34 staining in the same tumor (200x magnification) showed microvasculature in brown and poorly differentiated rectal adenocarcinoma. The MVD value is 43.
