目的 旨在探讨多层CT(MSCT)三 期增强扫描在肾脏肿瘤样病变的诊断价 值。方法 选取我院2015年9月-2016年9 月收治的经手术或病理证实的肾脏肿瘤样 病变患者52例，所有患者均进行CT平扫及 增强扫描，整理52例患者的临床及影像学 资料，以病理学检查结果为标准，分析CT 三期增强扫描对肾脏肿瘤样病变的诊断准 确率，并由两名经验丰富的放射科诊断 医师共同评估观察CT平扫与增强扫描图 像，对肾脏肿瘤样病变的影像特征进行 分析。结果 病理检查结果显示，52例患 者中：肾癌27例，肾盂乳头状癌19例， 肉瘤2例，其它4例。CT扫描对52例患者 的肺癌检出率为94.23%(49/52)，其中检 出肾癌26例，肾盂乳头状癌18例，肉瘤2 例，其它3例。CT增强扫描对肾脏肿瘤样 病变的确诊率与病理检查结果无明显差异 (χ2 =0.045，P=0.832)。CT平扫显示病灶 部位多为等密度或稍低密度，极少数病灶 部位出现稍高密度。患者肾脏病灶区在三 期动态CT增强扫描图像出现明显强化，且 病变周围组织以及分界显示清楚。结论 三期动态CT增强扫描图像能直观、全面的 准确显示病变区，且对肾脏肿瘤样病变具 有较高的诊断准确率，有利于影像医生对 病变部位进行精确定位显示，可为临床提 供重要影像学资料，帮助临床医生诊断， 指导临床医生制定正确的治疗方案，值得 临床推广和应用。

Objective To investigate the value of multi-slice CT (MSCT) three-phase enhanced scan in the diagnosis of renal tumor-like lesions. Methods A total of 52 patients with pathologically confirmed renal tumor-like lesions in our hospital from September 2015 to September 2016 were selected. All patients underwent CT scan and enhanced scan. The clinical and imaging data of 52 patients were sorted out. According to the results of pathological examination, the diagnostic accuracy of phase III enhanced CT in renal neoplasia was analyzed. Two veteran radiologists diagnosed the image of CT scan and contrast-enhanced scan, and analyzed the imaging features of renal tumor-like lesions. Results The pathological examination showed that in 52 patients, there were 27 cases of renal cell carcinoma, 19 cases of renal papilloma, 2 cases of sarcoma and 4 cases of other cases. Using CT scan, the detection rate of lung cancer in 52 patients was 94.23% (49/52). There were 26 cases of renal cell carcinoma detected, 18 cases of renal papilloma, 2 cases of sarcoma and 3 cases of others. There was no significant difference in the diagnosis of renal tumor-like lesions between CT enhanced scan and pathological examination (χ2 =0.045, P=0.832). CT plain showed lesions mostly equal density or slightly lower density, very few lesions appear slightly higher density. Patients with renal lesions in the three dynamic CT enhanced scan image was significantly enhanced, and lesions around the boundaries and the boundaries show clearly. Conclution The three-phase dynamic contrast-enhanced scanning (CT) images can provide an accurate and comprehensive visualization of the lesion area and have a high diagnostic accuracy for neoplastic tumorlike lesions. It is helpful for the imaging doctors to accurately locate and display the lesion site, which may be clinically important Imaging information to help clinicians diagnose and guide clinicians to develop the correct treatment options, it is worth clinical promotion and application.
