摘　　要：目的研究数字乳腺断层摄影(DBT)、超声(US)及磁共振成像(MRI)对浸润性乳腺导管癌(IDC)病灶大小的准确性分析。方法回顾性分析2019年3月至2020年8月经手术及病理确诊IDC患者83例,所有患者术前均行DBT、超声及MRI检查,并由两位放射科副主任医师进行病灶最大径测量,与手术切除新鲜标本病理测量值进行对比,比较各检查预估IDC病灶大小的准确性、差值分析,线性回归系数及相关性分析。结果DBT、US及MRI测量病灶最大径与病理测量值准确率分别是60.24%、60.24%、81.93%,MRI检查测量准确率最高,与DBT、US比较差异具有统计学意义(P<0.05);DBT、US、MRI测量病灶大小值与病理测量值的差值差异性分析(F=2.533,P<0.001),DBT、US及MRI测量值与病理测量值呈正相关性(r=0.679、0.668、0.851),MRI相关系数最高,标准误最低。结论DBT、US及MRI检查在测量IDC病灶大小中均与病理测量值的相关性良好,MRI对IDC病灶大小测量准确度最高,相关性最好,可以作为IDC术前预估病灶大小的依据。Objective To study the effect of digital breast tomosynthesis(DBT),ultrasound(ultrasound,US),and magnetic resonance imaging(MRI)on the size of invasive mammary ductal carcinoma(IDC)lesions Accuracy analysis.Methods A retrospective analysis of 83 patients with IDC diagnosed by menstrual surgery and pathology from March 2019 to August 2020 was performed.All patients underwent DBT,ultrasound,and MRI examinations before surgery,and two associate chief radiologists measured the maximum diameter of the lesion.Compare with the pathological measurements of fresh specimens resected by surgery,compare the accuracy of each examination to estimate the IDC lesion size,difference analysis,linear regression coefficient,and correlation analysis.Results The accuracy rates of the maximum diameter and pathological measurements of the lesions measured by DBT,US,and MRI were 60.24%,60.24%,and 81.93%,respectively.The accuracy of MRI examination was the highest,and the difference was statistically significant compared with DBT and US(P<0.05),;The difference between the lesion size measured by DBT,US,MRI,and the pathological measurement is analyzed(F=2.533,P<0.001),which is statistically significant;the DBT,US,and MRI measured values are positively correlated with the pathological measurement Sex(r=0.679,0.668,0.851),the correlation coefficient of MRI was the highest,and the standard error was the lowest.Conclusion DBT,US,and MRI have a good correlation with pathological measurements in the measurement of IDC lesion size.MRI has the highest accuracy and the best correlation for IDC lesion size measurement.It can be used as a basis for preoperative IDC estimation.
