Pleural pointillism is multiple high signal regions on b=1000 diffusion-weighted imaging but not at lower b-values. It can be a reliable tool allowing differentiation of malignant from benign pleural lesions and can help guide biopsy 1-3. Its sensitivity is reported to be 93-100% and specificity of 79-83% respectively 1,3.
