Whole Body MRI at 3T with Quantitative Diffusion Weighted Imaging and Contrast-Enhanced Sequences for the Characterization of Peripheral Lesions in Patients with Neurofibromatosis Type 2 and Schwannomatosis
Figure 1
Whole body MRI in a patient with NF-2 and multiple PNSTs, with good diagnostic quality. In (a), whole body STIR (quality ratings of 4 in all body parts except abdomen rating of 3) shows multiple PNSTs in the arm (vertical arrow), chest (short arrow), and thigh (long arrow). In (b), corresponding ADC maping (diagnostic quality of 3 in all body parts except in the arm and neck, where there was a rating of 1 in the arm and a rating of 2 in the chest) shows corresponding PNSTs in the chest (short arrow) and thigh (long arrow) with ADC values of 1.4 and mm−2, respectively. Lesion in the arm cannot be identified on the ADC map due to poor diagnostic quality in the arm. In (c), corresponding T1-weighted postcontrast whole body image shows homogeneous enhancement patterns of the chest, right arm, and thigh PNSTs.
