作者收集了15例肺癌,测量在体外手术标本的T_1、T_2值,并与正常组织比较。共98块标本。66块在镜下确认其组织特征,并分成五类:A.没有坏死的活性肿瘤组织;B.50%的肿瘤组织坏死;C.阻塞性肺炎的炎性组织;D.慢性阻塞性肺炎的机化性纤维组织;E.正常组织。各组T1平均值(±SD):A.1316±86秒,B.899±153秒,C.1218±93秒,D.925±109秒,E.1101±77秒。A和C明显长于其余三组。结果表明,炎性组织和活性肿瘤组织的T_1值无鉴别意义,却均比正常组织为长。分化好的腺瘤T1值短。坏死肿瘤组织亦较短。
The authors collected 15 cases of lung cancer and measured the T 1 and T 2 values of surgical specimens in vitro and compared them with normal tissues. A total of 98 specimens. Sixty-six microscopic examinations confirmed the histopathologic features and were divided into five groups: A. Active tumor tissue without necrosis; B. Necrosis of 50% tumor tissue; C. Obstructive pneumonia inflammatory tissue; D. Chronic obstructive pneumonia Mechanical fibrous tissue; E. Normal tissue. The average value of T1 in each group (±SD): A.1316±86 seconds, B.899±153 seconds, C.1218±93 seconds, D.925±109 seconds, E.1101±77 seconds. A and C are significantly longer than the remaining three groups. The results showed that the T1 values of inflammatory tissues and active tumor tissues had no discriminative significance, but they were all longer than normal tissues. Well-differentiated adenomas have short T1 values. Necrotic tumors are also shorter.
