| 目的 分析不同病理类型乳腺癌的3.0T MRI特征。 方法 回顾性分析经手术病理证实的94例乳腺癌患者资料,分析不同病理类型乳腺癌的形态、强化方式及时间-强度曲线(TIC)等MR影像特征。 结果 94例乳腺癌包括11例导管原位癌、5例浸润性导管癌Ⅰ级、44例浸润性导管癌Ⅱ级、20例浸润性导管癌Ⅲ级及14例其他病理类型。导管原位癌全部为均匀强化,72.73%(8/11)病灶形态为沿导管、小叶分布的多发结节状、片状;浸润性导管癌Ⅰ级病灶TIC 80.00%(4/5)为速升缓降型,60.00%(3/5)为分叶状,60.00%(3/5)均匀强化;72.73%(32/44)浸润性导管癌Ⅱ级病灶表现为分叶状及分叶状带毛刺,63.64%(28/44)为均匀强化,TIC 59.09%(26/44)为速升缓降型、22.73%(10/44)为速升平台型;90.00%(18/20)浸润性导管癌Ⅲ级病灶表现为分叶状和不规则形,80.00%(16/20)为均匀强化和边缘强化为主, TIC 50.00%(10/20)为速升缓降型、40.00%(8/20)为速升平台、速升缓降混合型。 结论 乳腺癌的MRI表现复杂多样,但不同病理类型的乳腺癌MRI表现有一定的特征性。 |

| Objective To analyze the MR features of different pathological types of breast cancer. Methods A total of 94 patients with different pathological types of breast cancer confirmed with surgery and pathology were reviewed. The preoperative morphology, enhancement features and dynamic contrast-enhanced time-intensity curve (TIC) types were described. Results The pathological diagnosis of 94 patients included 11 ductal carcinoma in situ (DCIS), 5 invasive ductal carcinoma grade Ⅰ (IDCG Ⅰ), 44 invasive ductal carcinoma grade Ⅱ (IDCG Ⅱ), 20 invasive ductal carcinoma grade Ⅲ (IDCG Ⅲ) and 14 other pathological types. All the DCIS evenly enhanced, and 8 (72.73%) of them showed multiple nodules, flakes enhancement along the duct or in lobular distribution. For 5 patients of IDCG Ⅰ, TIC type of 4 patients was speed up slow down type, in which 3 were irregular shape and 3 evenly enhanced. For IDCG Ⅱ, 32 (72.73%) were lobulated or lobulated with burr; 28 (63.64%) evenly enhanced; TIC showed a rapid rise to a peak followed by a slow decline in 26 patients, and a rapid rise followed by a plateau in 10 patients. For IDCG Ⅲ, lobulation and irregular shape were found in 18 patients, evenly enhanced in 9 and peripherally enhanced in 7. TIC showed rapid rise followed by slow decline in 10 patients, while in 8 patients TIC curve was described as rapid rise followed by a plateau combined with rapid rise followed by slow decline. Conclusion Although MR performance of breast cancer is complex and diverse, there is certain characteristics for different pathological types of breast cancer on 3.0T MR. |
