摘要目的 T2W-MRI与病理对照分析MR化学位移成像显示的乳头状肾细胞癌(p RCC)含有的细胞内脂质。方法本研究经伦理委员会批准。收集11年内经证实的62例p RCC病人MRI资料。由2名放射科医师独立评估MR化学位移成像(CS-MRI)病灶是否含有细胞内脂质以及病灶T2W-MRI信号均匀性。诊断医师间一致性采用组内相关性进行评估,结果采用卡方检验进行比较。对有异议病例重新阅 Abstract Objective To analyze the expression of intracellular lipids in papillary renal cell carcinoma (p RCC) by MR chemical shift imaging with T2W-MRI and pathology. Methods The study was approved by Ethics Committee. Sixty-two confirmed MRI data of patients with p RCC within 11 years were collected. Two radiologists independently assessed whether MR chemical shift imaging (CS-MRI) lesions contained intracellular lipids and focal T2W-MRI signal uniformity. Consistency between diagnosticians was assessed using in-group correlation and the results were compared using a chi-square test. Re-read the objection cases
