Nevertheless, these systems often require expensive software and dedicated workstations.īy contrast, OsiriX is an open-source Digital Imaging and Communications in Medicine (DICOM) viewer with the powerful capability of 3D volumetric rendering. Using these systems, one can gain a better understanding of the pathology of lesions and create a good 3D reconstruction of both the lesions and the surrounding normal anatomical structures. This process of transforming the data is most difficult at the beginning of one's career in early residency.įortunately, modern-day technology provides multiple aids in this regard: sophisticated neuronavigation systems, dedicated software for preoperative planning and simulation, the software of the internal workstation in the radiological department, and modern simulation technology. The difficulty comes from transforming the two-dimensional preoperative radiological black-and-white data into a three-dimensional (3D) image in the surgeon's mind, a view that represents the surgical position of the patient, the small cranial exposure, and the distortion of the normal anatomy caused by the lesion.
Correct and detailed preoperative planning is one of the most important prerequisites of successful surgery and is a skill that takes years to master and understand.
