Figure 1: Elastography of prostate cancer (stiff lesion). (a) A hypoechoic lesion without a clear boundary was found in the right peripheral zone of the prostate by TRUS (right image, white arrow), and a local blue region indicated the lesion by TRTE (left image, white arrow). (b ) The section stained with picric acid-sirius red showed that Col1 and Col3 were cross-linked in distribution. The collagen volume fraction of Col1 (0.05) was greater than that of Col3 (0.02). TRTE: Transrectal Real-Time tissue Elastography; TRUS: Transrectal Ultrasonography.
