Why is Restricted Diffusion Important in Cancer Diagnosis?
Restricted diffusion is a critical marker in cancer diagnosis for several reasons: - Cell Density: Malignant tumors have high cellularity, which restricts the diffusion of water molecules. This characteristic makes DWI a valuable tool for distinguishing between benign and malignant lesions. - Tumor Aggressiveness: Tumors with restricted diffusion typically exhibit high cellularity and aggressiveness. Low ADC values often correlate with high-grade tumors. - Early Detection: DWI can detect cancerous changes earlier than conventional MRI sequences, allowing for early intervention.
