Virtual endoscopy (VE) is a digital image processing method that can provide simulated 3D-visualizations of human hollow organs, similar to those produced by standard endoscopic procedures. VE enables the measuring of anatomic structures, which can simplify tasks like preoperative planning of endoscopic procedures and assessment of intracavity processes. The precision and reliability of the anatomic representation and measurements in VE are vital for these purposes. The aim of this study is to assess both aspects when applied to intracerebral cavities. In addition, phantom studies were done to assess the impact of unprecise measurements of objects of various sizes. The results suggest that VE can provide accurate, reproducible and clinically useful visualizations and measurements of the great ventricular structures. Technical limitations are the cause of inadequate representation of small anatomical structures, leading to unprecise measurements and currently limiting the clinical use of VE.
