Microstructural analysis of pineal volume using trueFISP imaging

Figure 1 TrueFISP imaging of the pineal region illustrating the spectrum of pineal volumes and cysts. A, B: Solid glands. Smallest pineal parenchyma volume (PPV), 5 mm³, the small pineal gland can hardly be demarcated from the habenula (A); largest PPV, 228 mm³ (B); C: Largest single cyst, 189 mm³. The pineal gland was axially reformatted along its long axis. the cystic part (CP) of the pineal gland is larger than the solid part (SP) and accounts for most of the pineal volume. Upper row: Axial reconstruction; Lower row: Sagittal reconstruction. 3^rd V: Third ventricle; AC: Anterior commissure; M: Mesencephalon; P: Pineal gland; QC: Quadrigeminal cistern.
