临床上,磁共振成像(MRI)可能在发现乳腺病变上比乳腺X线扫描更敏感,但在证实乳房病变后,它并不降低活组织检查的必要性。乳腺X线扫描是最常用的发现临床隐匿乳腺癌的成像工具,但无论在敏感性还是在特异性方面,它都有自身的局限。以往的研究表明,通过MRI看到的乳腺病变患者中,有27％-37％在乳房X线扫描上并不能看到(Radiology1993;187:493-501)。 Clinically, magnetic resonance imaging (MRI) may be more sensitive to mammographic findings than mammography, but it does not reduce the need for biopsies after breast lesions have been confirmed. Mammography is the most commonly used imaging tool for finding clinically occult breast cancers, but it has its own limitations, both in terms of sensitivity and specificity. Previous studies have shown that 27% -37% of breast lesions seen by MRI can not be seen on mammograms (Radiology 1993; 187: 493-501).
