目的:分析前列腺结节性病灶的超声造影参数的差异性,为前列腺结节的鉴别诊断提供依据。方法:对25位前列腺结节性病变患者(共发现32个可疑结节,其中良性结节16个,恶性结节16个)行超声造影检查,使用SonoLiver造影软件分析造影图像,获得病灶的时间-强度曲线(TIC),记录造影剂的到达时间(AT)、上升时间(RT)、达峰时间(TTP)和峰值强度(IMAX),最后分析两组指标有无统计学差异。结果:良性组TTP(17.03±5.60)s大于恶性组TTP(13.57±3.42)s,良性组IMAX(92.84±67.90)%小于恶性组IMAX(190.24±157.40)%,差异均有统计学意义(P<0.05);两组间AT、RT比较差异均无统计学意义。结论:超声造影相关参数在前列腺结节性病灶的鉴别诊断中具有一定的应用价值。
OBJECTIVE: To analyze the difference of contrast echocardiography parameters in benign prostatic nodules and provide basis for the differential diagnosis of prostatic nodules. Methods: Twenty-five patients with benign prostatic nodules (32 suspicious nodules, including 16 benign nodules and 16 malignant nodules) underwent contrast-enhanced ultrasonography. SonoLiver radiography software was used to analyze the contrast images to obtain the lesion time - intensity curve (TIC), time of arrival (AT), rise time (RT), peak time (TTP) and peak intensity (IMAX) of contrast medium were recorded. Results: The TTP in the benign group was significantly higher than that in the malignant group (13.57 ± 3.42) s, that in the benign group was 92.84 ± 67.90% (190.24 ± 157.40%), and the difference was statistically significant (P <0.05). There was no significant difference in AT and RT between the two groups. Conclusion: Contrast parameters of CEUS have certain value in the differential diagnosis of benign prostatic nodules.
