摘要
目的探讨经直肠超声造影在不同类型前列腺癌诊断及临床分期中的应用价值。方法使用SonoVue对66例前列腺癌患者行经直肠超声造影检查，观察病灶造影增强模式，用Q～LAB软件对病灶及其周围组织造影参数进行对比分析，并经直肠超声引导前列腺穿刺活检，取得病理结果，与超声造影表现进行对比分析，判定临床分期。结果按二维超声图像特点分为弥漫型27例，单侧型16例，结节型23例。弥漫型造影信号快进快出，分布紊乱。单侧型癌性病变区域造影信号紊乱，快速消退。癌性结节呈快进快出的高增强。结论经直肠超声造影在鉴别前列腺良恶性病变及判定病变范围，确定临床分期中有良好的临床应用价值。
Objective To investigate the value of transrectal contrast enhanced ultrasound in diagnosis and clinical staging of different types of prostate cancers. Methods Sixty-six patients with prostate cancer underwent transrectal contrast-enhanced ultrasound with a blot injection of SonoVue. Enhancement patterns of lesions were observed and comparative analysis of contrast parameters of lesions and surrounding tissues were performed off-line by dedicated QLAB software. All cases were examined by ultrasound-guided biopsy. Clinical staging was determined by comparing and analyzing contrast-enhancement patterns and pathological results. Results Twenty-seven cases were classified as diffuse infiltrative type, 16 cases of unilateral type, and 23 cases of focal nodules type, according to the characteristics of two dimensional ultrasound. The enhancement pattern of diffuse infiltrative type was contrast signal ＂fast in fast out＂ without well-distribution. Disordered enhancement in the lesions and fast elimination was observed in unilateral type. Focal nodules type showed high density enhancement with signal fast in and fast out. Conclusions Transrectal contrast-enhanced ultrasound has a significant clinical value for the differential diagnosis of prostatic carcinoid and malignancy, assessment of the lesion range and determining clinical staging of the prostatic lesions.
