Abstract

Background: Breast cancer is the leading cause of cancer-related mortality in Mexico, frequently diagnosed in young women and at advanced stages. Breast magnetic resonance imaging (MRI) is the most sensitive and specific method for its diagnosis, although access to it is limited. This study evaluates the concordance between the Kaiser score (KS) with and without the use of DWI/ADC sequences in patients with suspected breast cancer.

Objective: To analyze the concordance between the Kaiser score obtained with DWI/ADC sequences (KS) and without them (KS-).

Material and methods: A cross-sectional study with 48 patients conducted between October 2022 and October 2024 at the Hospital de Especialidades of the Centro Médico Nacional de Occidente, Guadalajara, Mexico. Cohen's Kappa statistic was used to evaluate concordance.

Results: A total of 48 breast MRIs from women with an average age of 44.33 years were analyzed. The KS scores were: 1 with score 4, 6 with score 6, 4 with score 7, 9 with score 8, 9 with score 9, 6 with score 10, and 15 with score 11. The KS- scores were: 1 with score 4, 6 with score 6, 3 with score 7, 9 with score 8, 9 with score 9, 6 with score 10, and 16 with score 11. Concordance was almost perfect (Kappa = 0.941, p < 0.001).

Conclusions: The Kaiser score without DWI/ADC (KS-) has almost perfect concordance with the score obtained with DWI/ADC (KS). Omitting DWI/ADC could reduce acquisition time, increase efficiency, and improve patient tolerance.

[乳腺MRI：有无弥散的Kaiser评分一致]。

背景：乳腺癌是墨西哥癌症相关死亡的主要原因，经常在年轻妇女和晚期妇女中被诊断出来。乳房磁共振成像（MRI）是最敏感和特异的诊断方法，尽管使用它是有限的。本研究评估了疑似乳腺癌患者使用和不使用DWI/ADC序列的Kaiser评分（KS）之间的一致性。目的：分析DWI/ADC序列（KS）与无DWI/ADC序列（KS-） Kaiser评分的一致性。材料和方法：在2022年10月至2024年10月期间，在墨西哥瓜达拉哈拉国立西方医学中心特别医院对48名患者进行了横断面研究。采用Cohen’s Kappa统计量评价一致性。结果：共分析了48例平均年龄44.33岁的女性乳房mri。KS分数依次为：4分1分、6分6分、7分4分、8分9分、9分9分、10分6分、11分15分。KS-得分为：4分1分、6分6分、7分3分、8分9分、9分9分、10分6分、11分16分。一致性几乎完全（Kappa = 0.941, p < 0.001）。结论：不带DWI/ADC的Kaiser评分（KS-）与带DWI/ADC （KS）的Kaiser评分几乎完全一致。省略DWI/ADC可以减少采集时间，提高效率，提高患者耐受性。
