Core Tip

Core Tip: This study systematically integrates contrast-enhanced ultrasound quantitative parameters with pathological markers (Ki-67 index and tumor grade) in pancreatic cancer for the first time. By combining ultrasonography, tumor pathology, and statistical methods, it provides a noninvasive approach to assess tumor proliferation and aggressiveness. The findings may enable more precise treatment decisions (e.g., surgery, chemotherapy, or targeted therapy), potentially improving clinical outcomes.
