Implantation of brain tumors with Cf-252. Use of computed tomography and magnetic resonance imaging to guide insertion and evaluate response
Y Maruyama, HW Chin, AB Young, PC Wang, P Tibbs, JL Beach and S Goldstein
Magnetic resonance imaging (MR) was evaluated as a guide to planning and
follow-up of Cf-252 neutron brachytherapy in 8 patients with malignant
glioma of the cerebral hemispheres. A combination of sagittal, transverse,
and coronal views allowed three-dimensional assessment of the dimensions
and extent of tumor; by comparison, CT scans delineated the tumor less
sharply, multiple views were not routinely obtained, and the reconstructed
sagittal images were inadequate. Both techniques were complementary in
enabling accurate tumor localization as well as separating enhanced zones
from central avascular regions and tumor from edema. However, MR images
provided more detail than serial CT scans, making MR the preferred method
of follow-up.
