肝脏占位性病变患者的超声造影与彩超影像分析

目的探索肝脏占位性病变患者的超声造影与彩超影像诊断和鉴别价值。方法回顾性调查2017年1月-2019年9月于某医院接受治疗的98例疑似肝脏占位性病变患者的临床资料,患者均接受超声造影和多普勒超声检查,对检查结果进行分析。结果超声造影的原发性肝癌93.33%、转移性肝癌78.95%、肝血管瘤92.31%、肝局灶性结节增生60.00%以及肝孤立性坏死结节80.00%,检出率高于多普勒超声检出率(P<0.05)。超声造影的总检出率为87.50%,高于多普勒超声的60.83%(P<0.05)。超声造影和多普勒超声对肿瘤直径>30 mm的检出率均为100%。超声造影的肿瘤直径介于10~30 mm的占84.42%、肿瘤直径<10 mm的检出率为72.73%,高于多普勒超声的检出率(P<0.05)。超声造影后恶性肿瘤的肿块开始实施时间(12.43±3.15)s、最大值时间(24.11±2.85)s以及消退时间(36.74±11.52)s均低于良性肿瘤和良性病变(P<0.05)。恶性肿瘤的肿块峰值强度(46.83±8.45)高于良性肿瘤和良性病变(P<0.05)。结论超声造影和多普勒彩超影响均能够用于肝脏占位性病变的诊断,但超声造影还能够对肿块的性质、大小进行鉴别,准确性较高。

Analysis of contrast-enhanced ultrasonography and Doppler color ultrasonography in patients with hepatic space-occupying lesions

Objective To explore the diagnostic and differential diagnostic values of contrast-enhanced ultrasonography and Doppler color ultrasonography in patients with hepatic space-occupying lesions. Methods The clinical data of 98 patients with suspected hepatic space-occupying lesions who were treated in a hospital from January 2017 to September 2019 were collected and retrospectively analyzed. The patients were examined by contrast-enhanced ultrasound and Doppler color ultrasonography. Results The detection rate of contrast-enhanced ultrasonography for primary liver cancer was 93.33%, the rate was 78.95% for metastatic liver cancer, the rate was 92.31% for hepatic hemangioma, the rate was 60.00% for liver focal nodular hyperplasia, and the rate was 80.00% for liver solitary necrosis, which were higher than those of Doppler color ultrasonography (P<0.05). The total detection rate of contrast-enhanced ultrasonography was 87.50%, which was higher than that of Doppler color ultrasonography of 60.83% (P<0.05). The contrast-enhanced ultrasonography and Doppler color ultrasonography showed a detection rate of 100% for tumor diameter >30 mm. The contrast-enhanced ultrasonography showed the detection rate of tumors ranged from 10 to 30 mm was 84.42% and the detection rate of tumor diameter <10 mm was 72.73%, which was higher than those of the Doppler color ultrasonography (P<0.05). The average time of onset of malignant tumor after the contrast-enhanced ultrasonography was (12.43±3.15) s, the maximum time was (24.11±2.85) s, and regression time was (36.74±11.52) s, which were shorter than those of benign tumors and benign lesions (P<0.05). The peak intensity of malignant tumors was (46.83±8.45), which was higher than that of benign tumors and benign lesions (P<0.05). Conclusion Both contrast-enhanced ultrasonography and Doppler color ultrasonography can be used for the diagnosis of hepatic space-occupying lesions, but the contrast-enhanced ultrasonography can also identify the nature and size of the mass, and the detection accuracy is higher. Therefore, the contrast-enhanced ultrasonography is more advantageous than Doppler color ultrasonography in diagnosing tumors.
