We introduce **3DLAND**, the first large-scale, **organ-aware** 3D lesion segmentation dataset for contrast-enhanced **abdominal CT scans**.
- 📦 **6,000+** CT volumes
- 🧠 3D Lesions labeled across **7 abdominal organs**: liver, kidneys, spleen, pancreas, stomach, gallbladder
- 🤖 Built using a **prompt-driven**, expert-verified segmentation pipeline
- ⚙️ Designed for tasks such as anomaly detection, lesion retrieval, and multimedia-driven clinical AI
This level of structured annotation would traditionally take **25+ years** of expert effort — 3DLAND accomplishes it in weeks using automated reasoning and deep learning.
