摘　　要：目的探析CT三期动态增强扫描诊断对肾癌患者的临床价值。方法选取2017年5月至2020年5月本院收治的58例经手术病理活检确诊肾癌的患者作为研究对象,所有患者经手术病理活检确诊为肾癌,接受CT三期动态增强扫描,以病理学活检作为金标准,分析CT三期动态增强扫描的临床价值。结果三期增强扫描准确率高于CT平扫,差异有统计学意义(P<0.05)。CT平扫后CT值为(32.18±8.55)HU,病灶直径平均(4.94±4.31)cm。大部分病灶为等密度状态,密度均匀,影像学主要表现为肾周间隙有“线状”“毛刺”结构;三期动态增强扫描发现患者动脉期CT值为(85.12±30.43)HU,实质期为(62.11±21.63)HU,大部分患者病灶外观为类圆形,6例表现为不规则形,在动脉期患者出现一定程度中-高度强化,大部分增强后边界清晰,大部分可发现有假包膜与“短刺”征,中心区诸如坏死、出血、囊变等情况无明显强化,在实质期强化程度呈递减变化,病灶区域有“快进快退”的特征,在静脉期扫描强化的程度有明显衰退。结论应用CT三期动态增强扫描肾癌患者诊断率较高,可帮助医生掌握患者病灶状态,为后续治疗方案制订提供可靠的参考数据。Objective To explore the clinical value of CT three-phase dynamic enhancement scan in diagnosis of renal cancer patients.Methods 58 patients with renal cancer diagnosed by surgical pathological biopsy admitted to our hospital from May 2017 to May 2020 were selected as research objects,all patients were diagnosed with renal cancer by surgical pathological biopsy,and received CT three-phase dynamic enhancement scan.Pathological biopsy is used as the gold standard comparison to summarize the clinical value of CT three-phase dynamic enhancement scan.Results After CT plain scan,the detection of renal cancer patients was lower than the CT three-phase dynamic enhancement scan,which was statistically significant(P<0.05).The average CT value of patients after plain CT scan was(32.18±8.55)HU,and the average lesion diameter was(4.94±4.31)cm.Most of the lesions are in an isodense state with uniform density,the imaging manifestations are mainly"linear"and"burr"structures in the perinephric space;the three-phase dynamic enhancement scan found that the patient's arterial phase CT average(85.12±30.43)HU,the parenchymal was(62.11±21.63)HU.The appearance of the lesions in most patients was round-like,and 6 patients showed irregular shapes,in the arterial stage patients,there was a certain degree of medium-to-high enhancement.It was found that there were false capsules and"short spines"signs,and the central area such as necrosis,hemorrhage,and cystic transformation showed no obvious enhancement.In the parenchymal phase,the degree of enhancement showed a decreasing change,there is a significant decline in the degree of periodic scan enhancement.Conclusion The application of CT threephase dynamic enhancement scan for renal cancer patients has higher diagnosis rate,which helps doctors grasp the patient's lesion status and provides reliable reference data for subsequent treatment plan formulation.
