Chest X-ray (CXR) imaging remains the primary screening modality for thoracic diseases, yet automated systems frequently struggle with concurrent multi-pathology detection and precise localization of subtle or diminutive lesions. Contemporary methods such as YOLOv11-MFF have sought to address these limitations through elaborate architectural enhancements, including frequency-adaptive gates and multi-scale fusion modules. In this work, we contest the premise that such architectural complexity is a prerequisite for leading performance. We show that a standard state-of-the-art detection backbone, coupled with principled data-centric strategies, renders bespoke domainspecific modules unnecessary. Our framework integrates Inverse-Frequency Weighted Upsampling to counteract long-tail class distributions and Anatomically-Constrained Test-Time Augmentation (CXR-TTA) to exploit the bilateral symmetry inherent to the thoracic cavity. On the VinDr-CXR benchmark, our approach attains a mean Average Precision (mAP@0.5) of 0.442, substantially exceeding the prevailing state-of-the-art without any custom neural network components. These results affirm that disciplined data-centric training strategies can outperform intricate architectural engineering in medical object detection.
