Sagittal view T2-weighted MR image (8500/80 [TR/TE]; section thickness, 3 mm), obtained at 3 T on a Bruker Medspec 30/100 system in the midsagittal plane, suggests tri-ventricular hydrocephalus due to aqueductal stenosis.
A, Third ventricular floor vaults toward the infundibular fossa.
B, Postoperative condition 8 months after surgery is shown.
- Fig 2.
3D rendering of the automatically segmented ventricular system during follow-up after endoscopic third ventriculostomy. The underlying 3D MR data sets were acquired preoperatively (T0) and postoperatively at 4 days (T1), 3 months (T2), and 8 months (T3) after the intervention. Measurement of the absolute ventricular volume yields 218, 177, 133, and 112 mL, respectively.

Shape difference of patient’s ventricular system. Colors indicate orientation and magnitude of shape difference; arrows indicate displacements.
A, Preoperative versus early postoperative status.
B, Superposition of displacement field, segmented ventricular system, and latest postoperative image obtained at the midsagittal plane.
C, Detailed view into anatomy of third ventricle shows tissue adaptations to altered intracranial pressure condition.
