【摘要】：目的探析老年胸腺肿瘤患者超声造影成像(CEUS)病变时间-强度曲线(TIC)的诊断价值。方法经CEUS确诊的48例老年胸腺肿瘤患者根据病灶的良恶性分成良性组18例和恶性组30例,分析病理检查结果、CEUS、彩色多普勒血流显像(CDFI)血流分级情况及灌注模式,比较两组常规超声检查结果、TIC的直接和间接指标等。结果两组常规超声显示的内部回声、边界、形态、CDFI差异不明显(P0.05)。在胸腺肿瘤及肺周围性病变的血供显示上,CEUS明显比CDFI优秀(P0.01)。良性组和恶性组血流灌注模式有所不同,恶性组和良性组的下降支斜率(DS)、下升支斜率(RS)、峰值强度(IMAX)、强度上升时间(RT)有统计学差异(P0.05),而达峰时间(TTP)和造影剂到达时间(AT)无统计学差异(P0.05)。结论 TIC对老年胸腺肿瘤及肺周围性病变患者诊断有重要价值。
[Abstract]:Objective to explore the diagnostic value of time-intensity curve (TIC) in elderly patients with thymic tumor by contrast-enhanced ultrasound (CEUs). Methods 48 elderly patients with thymic tumor diagnosed by CEUS were divided into benign group (n = 18) and malignant group (n = 30) according to benign and malignant lesions. The results of pathological examination and color Doppler flow imaging (CDFI) were analyzed to compare the direct and indirect indexes of TIC between the two groups. There was no significant difference in morphologic CDFI between the two groups (P 0.05). The blood supply of thymic tumors and peripheral pulmonary lesions was significantly superior to that of CDFI. The blood perfusion patterns of benign and malignant groups were different. In malignant group and benign group, there were no significant differences in the slope of descending branch and ascending branch, peak intensity and peak intensity of IMAXT, and time of intensity rise (P 0.05), but there was no significant difference between TIC and contrast medium arrival time (P 0.05). Conclusion TIC has no significant difference in elderly thymus. The diagnosis of tumor and peripheral pulmonary lesions is of great value.
