目的研究淋巴结转移瘤与肌肉CT灌注值的差异和相关性,并进行淋巴结转移瘤治疗前后比较。方法淋巴结转移瘤患者40例,测定淋巴结和相应层面肌肉的CT灌注值,其中部分淋巴结转移瘤病例于治疗后复查CT灌注值。结果转移性淋巴结与肌肉灌注值有显著差异,转移淋巴结治疗前与治疗后灌注值有显著差异。结论CT灌注成像法对淋巴结转移瘤的鉴别诊断及评价转移性淋巴结治疗效果和判断复发上具有临床应用价值。
Objective To study the difference and correlation between lymph node metastasis and muscle CT perfusion and to compare lymph node metastases before and after treatment. Methods Totally 40 patients with lymph node metastases were involved in this study. The CT perfusion values of the lymph nodes and the corresponding muscle layers were measured. CT perfusion values of some lymph node metastases were examined after treatment. Results There was a significant difference between the metastatic lymph nodes and the muscle perfusion values. There was a significant difference in the perfusion values between the metastatic lymph nodes before and after treatment. Conclusion CT perfusion imaging of lymph node metastasis of the differential diagnosis and evaluation of metastatic lymph node therapy and determine the recurrence has clinical value.
