摘　　要：目的观察前列腺良、恶性病变经直肠超声造影的基本特征,初步确立两者之间的超声造影剂灌注的不同特点。方法对30例PSA增高患者,采用SonoVue造影剂结合新型CPS造影成像技术,行超声造影,并观察造影全过程。对造影可疑区域实施穿刺,并同时行标准6点穿刺。结果15例前列腺增生造影剂灌注过程为内腺包膜及尿道部位先增强,紧接着内腺,最后为外腺包膜,外腺。消退的顺序则相反;即为外腺、内腺、内腺包膜及尿道周围区,6例前列腺增生结节,灌注方式为均匀性高增强,高于其周围内腺组织,边界清晰,有包膜,消退期基本与周围内腺组织一致。5例弥漫性前列腺癌的造影剂灌注为整体快速不均匀增强,内、外腺分界不清。4例外腺局灶性癌灶中2例表现为"快进慢出",2例属于"同进快出"。结论在经直肠前列腺超声造影中,良性病变灌注方式为均匀有规律性增强,内外腺分界清晰,而恶性病变则为无序、杂乱、快速增强,内外腺分界不清。前列腺良恶性病变的超声造影灌注方式有一定的规律性,故可作为鉴别诊断的有效方法之一。Objective To observe general prostate pathological characteristics by transrectal ultrasound perfusion imaging and to tell the differences between benign and malignant prostate alterations.Method The pathological alterations in 30 patients with elevated PSA were observed using a new CPS imaging technology combined with SonoVue imaging reagent during the ultrasound perfusion. The puncture was implemented at the region with contrast suspicious, and conventional puncture was performed at 6 points.Results In 15...
