Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

5.7K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computational Anatomy

Background:

  • Trigeminal neuralgia is a debilitating neurological condition.
  • Current treatments involve puncturing the trigeminal nerve via the foramen ovale.
  • Anatomical variations and complexity of the skull base make precise surgical navigation challenging.

Purpose of the Study:

  • To develop an automated image segmentation solution for the foramen ovale.
  • To enhance computer-aided navigation for trigeminal neuralgia treatment.
  • To overcome the limitations of manual foramen ovale segmentation.

Main Methods:

  • Implementation of a multiatlas-based image segmentation approach.
  • Development of a dataset comprising 30 CT scans (20 atlas, 10 testing).
  • Validation of the method for segmenting the foramen ovale in surgical scenarios.

Main Results:

  • Successful automatic segmentation of the foramen ovale using the multiatlas method.
  • Demonstrated efficacy of the approach with limited data.
  • Potential for accurate localization of the foramen ovale for surgical planning.

Conclusions:

  • The proposed multiatlas method offers an automated and reliable solution for foramen ovale segmentation.
  • This technology can significantly aid surgeons in computer-aided puncture guidance for trigeminal neuralgia.
  • The method shows promise as a valuable tool for clinical application in neurosurgery.
