, , , , , , , Our study evaluated the effectiveness of the Botucatu Abbreviated Protocol in breast magnetic resonance imaging (MRI) within Brazil’s public healthcare system, focusing on its impact on patient access to MRI exams.
This retrospective study involved 197 breast MRI exams of female patients over 18 years with histological breast carcinoma diagnosis, conducted at Hospital das Clínicas de Botucatu - UNESP between 2014 and 2018. Two experienced examiners prospectively and blindly analyzed the exams using an Integrated Picture Archiving and Communication System (PACS). They first evaluated the Botucatu Abbreviated Protocol, created from sequences of the complete protocol (PC), and after an average interval of 30 days, they reassessed the same 197 exams with the complete protocol. Dynamic and morphological characteristics of lesions were assessed according to BI-RADS 5th edition criteria. The study also analyzed the average number of monthly exams before and after the implementation of Botucatu Abbreviated Protocol.
The Botucatu Abbreviated Protocol showed high sensitivity (99% and 96%) and specificity (90.9% and 96%). There was a significant increase in the average monthly MRI exams from 6.62 to 23.8 post-implementation.
The Botucatu Abbreviated Protocol proved effective in maintaining diagnostic accuracy and improving accessibility to breast MRI exams, particularly in the public healthcare setting.

To assess the feasibility and diagnostic accuracy of preoperative ultrasound combined with ultrasound-guided fine-needle aspiration (US-FNA) cytology and clinical examination of axillary lymph node in patients with breast cancer.
In this prospective study, 171 axillae of patients with breast cancer were evaluated by clinical examination and ultrasonography (US) with and without fine needle aspiration (FNA). Lymph nodes with maximum ultrasonographic cortical thickness > 2.3 mm were considered suspicious and submitted to US-FNA.
Logistic regression analysis showed no statistically significant correlation between clinical examination and pathologically positive axillae. However, in axillae considered suspicious by ultrasonography, the risk of positive anatomopathological findings increased 12.6-fold. Cohen's Kappa value was 0.12 for clinical examination, 0.48 for US, and 0.80 for US-FNA. Accuracy was 61.4% for clinical examination, 73.1% for US and 90.1% for US-FA. Receiver Operating Characteristics (ROC) analysis demonstrated that a cortical thickness of 2.75 mm corresponded to the highest sensitivity and specificity in predicting axillary metastasis (82.7 and 82.2%, respectively).
Ultrasonography combined with fine-needle aspiration is more accurate than clinical examination in assessing preoperative axillary status in women with breast cancer. Those who are US-FNA positive can be directed towards axillary lymph node dissection straight away, and only those who are US-FNA negative should be considered for sentinel lymph node biopsy.
