Background And Purpose: Parotid lesions show overlaps of morphological findings, apparent diffusion coefficient (ADC) values and types of time/intensity curve. This research aimed to evaluate the role of diffusion weighted imaging texture analysis in differentiating between benign and malignant parotid lesions and in characterizing pleomorphic adenoma (PA), Warthin tumor (WT), epithelial malignancy (EM), and lymphoma (LY).
Methods: Texture analysis of 54 parotid lesions (19 PA, 14 WT, 14 EM, and 7 LY) was performed on ADC map images.
Article Synopsis
- The study aimed to evaluate the effectiveness of diffusion-weighted imaging (DwI) and dynamic contrast-enhanced perfusion-weighted imaging (DCE-PwI) in identifying benign and malignant salivary gland tumors.
- Results indicated that benign tumors were linked to higher ADC values (≥1.4 × 10 mm/s) and type A curves, while malignant tumors showed lower ADC values (0.9-1.4 × 10 mm/s) and type C curves, demonstrating high specificity and positive predictive value for cancers.
- The findings suggest that lower ADC values (<0.9 × 10 mm/s) along with specific imaging patterns can effectively differentiate between types of tumors, achieving high diagnostic accuracy for conditions
