OBJECT The diagnostic usefulness of (11)C-methionine PET scans in gliomas is still controversial. The authors investigated the clinical significance of (11)C-methionine PET findings in preoperative diagnosis of histological type and grade. METHODS The tissue uptake of (11)C-methionine was assessed using PET in 70 patients with histologically confirmed(More)
Conservative management, gamma-knife (GK) radiosurgery, and microsurgery are therapeutic options for acoustic neurinomas (ANs). To determine the outcomes and risks of these methods this systematic review analyzed data from 903 patients with conservative management, 1475 with GK radiosurgery, and 5005 with microsurgery from 38 studies identified in MEDLINE(More)
BACKGROUND AND PURPOSE Perivascular (PV) spaces are known to distend and cause edema along the optic tract (OT) in pituitary-region tumors. Interstitial fluid may be retained in PV spaces when tumors block their drainage outlets to subarachnoid spaces. However, these spaces and their outlets have not been anatomically elucidated. Our purpose was to evaluate(More)
The purpose of this study is to examine the relation between Glasgow Coma Scale (GCS) score and findings on computed tomography (CT) and magnetic resonance (MR) imaging of patients with mild head injury presenting GCS scores between 13 and 15. Data were collected from all consecutive patients with mild head injury who were referred to our hospital between(More)
BACKGROUND AND PURPOSE Edema-like change along the optic tract commonly occurs in association with craniopharyngiomas. The aim of this study was to clarify whether it occurs in association with other common pituitary region tumors and to elucidate its mechanism as seen on MR images. METHODS Fifty patients with pituitary region tumors that were touching or(More)

ABSTRACT Objective Chromosome 1p/19q deletion is an established prognostic and predictive marker in the WHO grade III oligodendroglial tumours (OT). To estimate the genetic status preoperatively, the authors investigated the correlation between the uptake(More)
The prognostic significance of the variety of changes in the internal auditory meatus (IAM) caused by vestibular schwannoma was retrospectively analyzed in 69 consecutive patients with vestibular schwannoma. Preoperative bone-window computed tomography was used to classify IAM changes into extensive destruction (17%), widening (46%), and normal IAM (36%).(More)
We retrospectively analyzed the clinicopathologic findings, treatment and outcome of 22 patients with synchronous or metachronous carcinomas of the esophagus and head and neck. The patients with metachronous cancers in whom esophageal cancer occurred first had either an early-stage esophageal carcinoma or only one positive lymph node. Similarly, five of 10(More)
PURPOSE The purpose of this study was to retrospectively assess the feasibility of radiation therapy planning for glioblastoma multiforme (GBM) based on the use of methionine (MET) positron emission tomography (PET), and the correlation among MET uptake, radiation dose, and tumor control. METHODS AND MATERIALS Twenty-two patients with GBM who underwent(More)
OBJECTIVE Chromosome 1p/19q deletion is an established prognostic and predictive marker in the WHO grade III oligodendroglial tumours (OT). To estimate the genetic status preoperatively, the authors investigated the correlation between the uptake of (11)C-methionine in positron emission tomography (PET) and the 1p/19q status in grades II and III OT.
