目的探讨磁共振(MR)动态增强联合弥散加权成像对乳腺疾病的检验效果。方法 81例乳腺疾病患者,随机分为对照组(40例)和联合组(41例)。对照组行单纯MR动态增强检查,联合组行MR动态增强扫描联合弥散加权成像检查,对比检验结果的准确性。结果对照组检测阳性结果28例(乳腺增生15例,乳腺癌13例),联合组检测阳性结果36例(乳腺增生19例,乳腺癌17例),联合组检测总阳性率87.80%(36/41)高于对照组70.00%(28/40),差异具有统计学意义(P<0.05);对照组检测乳腺癌13例(病灶21个),联合组检测乳腺癌17例(病灶30个)。联合组乳腺癌恶性病灶检出率85.71%(18/21)高于对照组53.85%(7/13),差异具有统计学意义(P<0.05)。结论在诊断乳腺疾病过程中,诊断医师对于疑似乳腺疾病患者采用MR动态增强联合弥散加权成像进行检验,提高诊断准确性,降低漏诊率和误诊率,以期达到早期诊断和指导临床治疗的目的,值得临床推广应用。
Objective To investigate the effect of magnetic resonance (MR) dynamic contrast-enhanced diffusion weighted imaging on breast disease. Methods 81 cases of breast disease were randomly divided into control group (40 cases) and combined group (41 cases). The control group underwent simple MR dynamic contrast-enhanced MR examination combined with diffusion-weighted imaging in the combined group. The accuracy of the test results was compared. Results The positive results of the control group were 28 cases (15 cases of breast hyperplasia and 13 cases of breast cancer), 36 cases (19 cases of mammary gland hyperplasia and 17 cases of breast cancer) in the combined group. The positive rate in the combined group was 87.80% (36 / 41) were higher than 70.00% (28/40) in the control group, the difference was statistically significant (P <0.05); the control group detected 13 cases of breast cancer (21 lesions), the combined group detected 17 cases of breast cancer (30 lesions) . The detection rate of malignant lesions in the combined group was 85.71% (18/21) higher than that in the control group (53.85%, 7/13), the difference was statistically significant (P <0.05). Conclusion In the diagnosis of breast disease, the diagnosis of patients with suspected breast disease by dynamic MR combined with diffusion-weighted imaging test to improve the diagnostic accuracy and reduce the rate of missed diagnosis and misdiagnosis rate in order to achieve the purpose of early diagnosis and guidance of clinical treatment, it is worth Clinical application.
