Synopsis
Usefullness of intraoperative MRI foe gloma surgery, Akira Matsumura et al.
b
At University
of Tsukuba hospital, total navigation system “VISIUS Surgical
Theatre” including 1.5
Tesla movable intraoperative MRI (i-MRI) has been installed and have been using
from January, 2013 for 213 cases. The main usage is glioma surgery with
craniotomy, trans-nasal pituitary, chordoma, meningioma surgery and deep brain
stimulation catheter insertion surgery.
The brain shift after craniotomy
is one of the major obstacle in defining the real border of the tumor and if
only image guided navigation for the preoperative MRI has been used, there will
be insufficient tumor removal in the deeper region. The usage of dual i-MRI and
5-ALA may improve the reliability of the gross total removal (Eyüpoglu IY
et al., 2012). The injury of the fibers, especially motor and language fibers
reduce the quality of life after surgery and brain shift may lead to the
misleading localization and this could be also overcome by using i-MRI (Kuhnt D,
2012)
In our institution, for glioblastoma
surgery, the usage of i-MRI increased the rate of gross total removal and also
contributed to the elongation of median survival. This fact is also proven by
RCT (Senft C,
2011) and systemic
review (Kubben PL,
2011). Acknowledgements
