摘要
目的讨论在肾脏良、恶性病变鉴别诊断中应用超声造影的临床应用价值。方法选取2015年5月-2016年5月,我院接收的肾脏占位性病变患者65例,进行实时超声造影检查,储存并对图像进行定量分析,测定造影剂到达时间、达峰时间,廓清时间、峰值强度与自身肾皮质对照。结果 65例患者中恶性病变34例,其中快进快退型有26例,快进慢退型有3例,慢进慢退型5例;良性病变31例,其中肾血管平滑肌瘤慢进慢退型有4例,2例峰值强度较低;不典型囊肿病变区均无肾皮质增强表现;肾柱细胞均无结节样表现,肥大脊柱与肾皮质等增强。结论超声造影能够直观地反应肾脏病变的血流灌注特点,对于肾脏良、恶性病变的诊断具有积极意义。
Objective To discuss the clinical value of contrast-enhanced ultrasonography in the differential diagnosis of benign and malignant renal lesions. Methods From May 2015 to May 2016, 65 cases of renal spaceoccupying lesions were collected and analyzed by real-time contrast-enhanced ultrasonography. The time of arrival, peak time and clearance of contrast agent were measured, to control time, peak intensity and renal cortical. Results Among the 65 patients, 34 cases were malignant, including 26 cases of fastforward and fast-withdrawing, 3 cases of fast-forward and slow-withdrawing, 5 cases of slow-slow and slow-withdrawing; 31 cases of benign lesions, including renal angiomyolipoma There were 4 cases of slow-withdrawing, 2 cases of low peak intensity; atypical cystic lesions were no renal cortical enhancement performance; renal column cells showed no nodular-like performance, hypertrophy of the spine and renal cortex increased. Conclusion Contrastenhanced ultrasonography can directly reflect the blood perfusion characteristicsof renal lesions,which is of positive significance in the diagnosis of benign and malignant renal lesions. It is worthy to be popularized in clinical practice.
