Abstract:
OBJECTIVETo analyze and evaluate the characteristics of benign prostatic hyperplasia (BPH) on contrast-enhanced ultrasound.
METHODSForty-eight BPH patients confirmed by transrectal ultrasound-guided biopsy underwent contrast-enhanced ultrasound. Contrast pulse sequencing technique (CPS) and quantitative software-ACQ were used, and the parameters of beginning enhancement time, disappearing and transit time and peak intensity (PI) of the inner gland and outer gland were recorded and analyzed.
RESULTSThe prostate was rich with blood and enhanced significantly on contrast-enhanced ultrasound. The beginning enhancement time of the prostatic inner gland, especially the area around the urethra, was much earlier than that of the outer gland, (26.68 +/- 3.76) and (31.24 +/- 5.33) s, respectively (P = 0.000). The contrast disappeared later in the inner gland than in the outer gland, (200.68 +/- 59.40) and (157.56 +/- 50.66) s, respectively (P = 0.000). The transit time of the contrast in the inner gland was much longer than in the outer gland, (173.94 +/- 60.14) and (129.21 +/- 56.91) s, respectively (P = 0.000). PI of the inner gland was much higher than that of the outer gland, (90.45 +/- 42.19) and (65.32 +/- 25.15) dB, respectively (P = 0.000).
CONCLUSIONContrast-enhanced ultrasound makes it possible to continuously observe the blood perfusion process of BPH, and promises to be an effective means for observing the blood supply in BPH.
