Real-time deep learning for tumor segmentation and tool tracking: development and validation of an AI navigation system in vacuum-assisted breast biopsy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundVacuum-assisted breast biopsy (VABB) is a widely adopted minimally invasive technique for the diagnosis and treatment of breast lesions. However, the procedure heavily relies on real-time ultrasound guidance, posing significant challenges for junior surgeon who lack radiological experience in accurately localizing both the lesion and the biopsy needle. Currently, there is no dedicated real-time artificital intelligence (AI) navigation system specifically designed for VABB procedures.
methodsWe developed a novel two-stage real-time AI navigation system based on the YOLOv11 deep learning architecture. Model 1 performs initial localization of the tumor and the cutter slot, while Model 2 focuses on real-time tracking of the knife and tumor during resection. The system was trained and validated using 22,278 annotated ultrasound images from 167 VABB procedures conducted at People's Hospital of China Medical University. A rigorous three-fold cross-validation was implemented to assess model performance, and the localization accuracy was compared with that of junior surgeon. Additionally, we evaluated the system's real-time processing performance on both GPU and CPU platforms.
resultsThe AI system demonstrated superior performance across all evaluated metrics. ForModel 1, the mean Average Precision at IoU threshold 0.5 (mAP50) for tumor detection and groove localization reached 0.907 and 0.671, respectively, significantly outperforming junior surgeon (0.551 and 0.120). For Model 2, the mAP50 for tumor and needle tip tracking were 0.829 and 0.765, respectively, compared to 0.758 and 0.350 achieved by surgeons. The system achieved a real-time processing speed of 1.2 ms per frame on GPU and 32.6 ms per frame on CPU.
conclusionThis study presents the first dedicated AI-based navigation system for VABB, showing substantial improvement in localization accuracy over manual operation by junior surgeon. The system's robust detection capability and real-time performance highlight its strong potential for clinical application, especially in surgical training and complex cases requiring precise instrument control.
