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 4
Images of well differentiated rectal adenocarcinoma with T1 stage. (a) Endorectal ultrasonography showed that an irregular hypoechoic lesion invaded both the mucosa and submucosa layer. (b) Time-intensity curve was obtained from ROI with EI = 25.21 dB, AT = 13.01 s, TTP = 25.12 s, WIT = 12.11 s, and AS = 2.08. (c) Representative photomicrographs of Immunohistochemical CD34 staining in the same tumor (200x magnification) showed microvasculature in brown and well differentiated rectal adenocarcinoma. The MVD value is 16.
