Computed Tomography (CT) Reconstruction for Axillary Lymph Node Structure
Computed Tomography (CT) Reconstruction for Axillary Lymph Node Structure
This is a prospective, single-center, non-randomized, non-controlled observational study.
The negative predictive value of ultrasound for lymph node with neoadjuvant chemotherapy is
 low, magnetic resonance imaging (MRI) or PET/CT did not significantly improve specificity to
 axillary lymph node. The aim of this study is to determine performance of computed tomography
 (CT) reconstruction on evaluation of lymph node status after neoadjuvant chemotherapy in
 breast cancer patients.
Inclusion Criteria:

 -  Invasive breast cancer with axillary lymph node metastasis by confirmed by fine needle
 aspiration (FNA) or core needle biopsy (CNB).

 -  Underwent computed tomography (CT) reconstruction for assessment of axillary lymph
 node status before and after neoadjuvant chemotherapy (NAC).

 -  Attend the study voluntarily, sign the informed consent.

 Exclusion Criteria:

 -  Contradiction for adjuvant chemotherapy.

 -  Contradiction for proceeding surgery.
