Quantitative T2 mapping and DW-IVIM parameters could provide valuable information and serve as a supplementary imaging marker for differentiating malignant from benign SPNs.
A-D A adenocarcinoma in the left upper lobe (A) An axial ADC mapping. (B) D map. (C) T2 map. (D) Hematoxylin-eosin staining confirms the nodule which is associated with nuclear polymorphism, higher cellularity and nuclear-to-cytoplasmic ratios which make ADC value, D value, and T2 value down.E-H A ball pneumonia in the right middle lobe. (E) An axial ADC mapping. (F) D map. (G) T2 map. (H) Hematoxylin-eosin staining confirms the nodule was characterized by more extracellular fluid spec and tissue fluid which would make ADC value, D value and T2 value rise.
