Abstract

Current methodologies for outcome assessment of coiled cerebral aneurysms are based on rough estimations. The aim of this study was to develop a system of quantitative analysis for objective and accurate assessment of the outcome of cerebral aneurysms treated with coil embolization. The quantitative analysis system is based on a concept of a perfect vessel tube and compartmentalized analysis of a coiled aneurysm. Based on the volumetric data of 3-dimensional radiographic angiography of the aneurysm and its associated parent vessel, a 2-step volume extraction method, including a global thresholding method and an augmented vessel method, is used for volume calculation. The coiled aneurysm (A) is compartmentalized into 2 volumetric components for quantitative analysis: 1) the volume of the coil mass (C), and 2) the volume of the uncoiled neck of the aneurysm (N). Changes in the volumetric data of the compartments A, C, and N at the time of follow-up provide a basis for outcome analysis. To test the clinical applicability of the system, the volumetric data for 21 consecutive cases of cerebral aneurysms in which a residual or recurrent cavity at the neck region was noted at the time of the 6-month follow-up evaluation were assessed ...Continue Reading

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
