【摘要】 本文通过112例肺部球形病灶的X线像资料,采用逐步判别函数方程式,又选用最大似然法制成计量诊断指数表作为计量诊断之用。经验证符合率为80.4%,比目测诊断符合率提高5%,如作良性和恶性二类鉴到,其符合率为90～93.6%,比目测诊断率提高15～18%。更多还原

【Abstract】 Radiographic materials of 112 cases ofpulmonary nodular lesion were treated with themethod of equation of stepwise discriminantfunction and the maximum likelihood method.A table of computer digital diagnosis was thuscompiled. The accuracy of computer diagnosiswas 80. 4%, it was 5% higher than the routineeye diagnosis. If used only for the differentialdiagnosis between benign and malignant lesions,its accuracy was about 90--93. 6%, ie, about15--18% over the routine eye diangosis.更多还原
