We report a series of studies that assess the feasibility and sensitivity of imaging of herpes
virus type one thymidine kinase (HSV1-tk) gene transfer and expression with [ 124 I]-5-iodo-2…

Vascular endothelial growth factor (VEGF), also known as vascular permeability factor, has
been investigated as a potent mediator of brain tumor angiogenesis and tumor growth. We …

Background. Noninvasive measurements of cerebral circulation and metabolism may be useful
for diagnosis in patients with brain tumors. The authors tested the prognostic significance …

Object. The authors of this study evaluated the efficacy of simultaneous microscopic and
endoscopic monitoring during surgery for internal carotid artery (ICA) aneurysms. Methods. The …

Rapid immunohistochemistry (R-IHC) can contribute to the intraoperative diagnosis of central
nervous system (CNS) tumors. We have recently developed a new IHC method based on …

Introduction Amino acid PET tracers are promising for visualizing gliomas and evaluating
radiochemotherapeutic effects. We compared the glioma detection and early response …

A case of gliomatosis cerebri was studied with positron emission tomography (PET). Carbon-11-L-methionine
(11C-Met) accumulated in the diffusely infiltrative tumorous area more …

Object. The characteristics of a previously unclassified paraclinoid aneurysm arising from
the anterolateral (dorsal) wall of the proximal internal carotid artery were retrospectively …

Dissemination of glioblastoma was once considered rare but is now increasingly encountered
with longer survival of glioblastoma patients. Despite the potential negative impact of …

Amino acid imaging is increasingly being used for assessment of brain tumor malignancy,
extent of disease, and prognosis. This study explores the relationship between proliferative …
