摘　　要：目的：探讨采用乳腺X线摄影计算机辅助诊断系统（CAD）软件与乳腺MRI测量软件评价乳腺密度的相关性。方法回顾性分析行乳腺X线摄影及MRI检查，且两项检查的间隔时间〈2个月的110例女性患者的影像资料。乳腺X线摄影检查采集的原始图像经CAD系统Quantra软件处理，计算机自动计算出乳房体积、乳房腺体体积及乳腺密度。将乳腺MRI图像导入医学影像定量分析PMOD软件测量乳房体积和乳房腺体体积，计算得出乳腺密度。采用Pearson相关检验评价乳腺X线CAD系统Quantra软件和MRI PMOD软件测得的乳房体积、乳房腺体体积及乳腺密度的相关性。结果乳腺X线CAD系统Quantra软件测得的乳房体积、乳房腺体体积和乳腺密度分别为（535±282） cm3、（106±69）cm3和（21±9）%，MRI PMOD软件测得的上述值分别为（487±260）cm3、（94±64）cm3和（20±9）%，二者的值均具有强相关性（r值分别为0.988、0.979和0.944，P均〈0.01）。结论乳腺X线CAD系统Quantra软件和乳腺MRI PMOD软件评价乳腺密度具有强相关性。Objective To discuss the correlation between the breast density measured by software of the computer aided detection （CAD） system and MRI software. Methods Retrospective analysis of 110 cases of female patients with mammography and MRI was performed, and the time interval of the two examinations was less than 2 months. Images of mammography were fed into CAD system with Quantra software processing, the computer automatically calculated the breast volume, mammary gland volume and the breast density. MRI images imported into PMOD breast volume and mammary gland volume measurement software,breast volume, mammary gland volume, and breast density were generated by the software. The correlation of CAD system Quantra software and MRI PMOD software was made by Pearson mehtodamong the breast volume, mammary gland volume and the breast density. Results Mammography CAD system Quantra software measured breast volume, mammary gland volume and breast density were （535±282） cm3, （106±69） cm3 and （21±9）%, the values measured by MRI PMOD software were （487±260） cm3,（94±64） cm3 and（20±9）%. The values of the two examination have high correlation （r were 0.988, 0.979 and 0.944; P〈0.01）. Conclusion Measurements of breast volume, mammary gland volume, and breast 〈br〉 density obtained using Mammography CAD system and MRI PMOD software appear to have excellent correlation.
