Comparative Study of Multiple High-Signal-Intensity Spots on 3D and 2D Magnetic Resonance Sialography for Patients with Sjögren’s Syndrome

Figure 5

A case of understaging by axial 3D MR-S compared with the staging by 2D MR-S. Sagittal 3D (a), axial 3D (b), and sagittal 2D MR-S can all detect MHS. While the axial 3D MR-S (b) result was stage 2, sagittal 3D (a) and 2D (c) MR-S results indicated stage 3. The axial 3D MR-S (b) was not able to detect a larger size of MHS due to being out of imaging range. MR-S: magnetic resonance sialography; MHS: multiple high-signal-intensity spots.
