Potential of 80-kV high-resolution cone-beam CT imaging combined with an optimized protocol for neurological surgery

Abstract

Eighty-kilovolt high-resolution CBCT has the potential to provide detailed anatomy for neurosurgical operations when utilizing suitable modes and contrast protocols.

Integrating 3D Rotational Angiography into Gamma Knife Planning

“…No changes are required in the geometric or patient information; thus, the image quality itself is intact. Because 3DRA is a CT-like image, being characteristic of the finest spatial resolution for high-contrast objects with poor contrast resolution and thus having many features common to CT, 22,23 stereotactic CT would be the best reference image for the coregistration. 18 By means of high-definition images, physicians can not only reduce unwanted waste radiation to the surrounding brain tissues but also enable a safe prescription of high radiosurgical doses, enough to obliterate the nidus, which might theoretically lead to improvement in the obliteration rate as well as a decrease in radiation-induced adverse events.…”

Usefulness of Intraoperative 2D-Ultrasound in the Resection of Brain Tumors

“…For this reason, there is a need to incorporate an intraoperative procedure that allows to evaluate these changes. Different solutions have been proposed, such as intraoperative MRI, cone beam computed tomography, stereoscopic cameras, fluorescence materials, and the incorporation of computer software's [21][22][23]. However, the use of iUS continues to be a very attractive option compared to other modalities, due to its accessibility (low cost), minimal interruption of surgery, and absence of radiation.…”
