3D pcASL MRI, especially with short PLD was suggested to evaluate patients with parotid gland tumors in routine clinical practice.
Figure 2. Representative images of PA (A-F), WT (J-L) and squamous cell carcinoma (M-R). The first column was the fat-suppressed T2-weighted image (A, J, M). The second (B, H, N), third (C, I, O), fourth (D, J, P), fifth (E, K, Q) and sixth (F, L, R) columns were TBF maps at different PLDs (PLD=1025ms, 1525ms, 2025ms, 2525ms, 3025ms), respectively. WT (H-L) showed relatively highest TBF, followed by squamous cell carcinoma (N-R) and PA (B-F). The unit of TBF is ml/100g/min. TBF= tumor blood flow; PLDs= post-labeling delay times; PAs= pleomorphic adenomas; WTs= warthin’s tumors.
Figure 1. Line graphs showing the changes of TBF at different PLDs. TBF= tumor blood flow; PLDs= post-labeling delay times; PAs= pleomorphic adenomas; WTs= warthin’s tumors; MTs= malignant tumors.
