Abstract Purpose To investigate 18F-fluoro-ethyl-tyrosine positron emission tomography (FET-PET) imaging characteristics of adult brainstem glioma (BSG). Materials and methods FET-PET imaging and progression-free survival (PFS) of 16 adult patients with BSG was analyzed (9 high-grade gliomas, 7 low-grade gliomas). SUVmax, TBR, and time activity curves of FET-PET were calculated. Results Progressive gliomas had higher SUVmax (3.57 ± 1.47 vs. 1.60 ± 0.51; p = 0.003) and TBRmax (3.00 ± 1.12 vs. 1.36 ± 0.33; p = 0.001) than stable gliomas. Kaplan-Meier analysis showed longer PFS of tumors with TBRmax   2.0 (665 ± 32 days versus 220 ± 39 days; p  Conclusion FET-PET uptake might be associated with disease progression in adult BSG.

Radiographic endpoints including response and progression are important for the evaluation of new glioblastoma therapies. The current RANO criteria was developed to overcome many of the challenges identified with previous guidelines for response assessment, however, significant challenges and limitations remain. The current recommendations build on the strengths of the current RANO criteria, while addressing many of these limitations. Modifications to the current RANO criteria include suggestion...

A previous review published in 2012 demonstrated the role of clinical PET for diagnosis and management of brain tumors using mainly FDG, amino acid tracers, and 18 F-fluorothymidine. This review provides an update on clinical PET studies, most of which are motivated by prediction of prognosis and planning and monitoring of therapy in gliomas. For FDG, there has been additional evidence supporting late scanning, and combination with 13 N ammonia has yielded some promising results. Large neutral a...

Background:Despite an increasing number of O-(2-18F-fluoroethyl)-L-tyrosine (18F-FET) PET studies in supratentorial gliomas, studies regarding the usefulness of 18F-FET PET in brainstem and spinal cord gliomas to date remain scarce. Methods:Thirty-six 18F-FET PET scans were performed in 29 patients with brainstem (n = 29 scans) or spinal cord glioma (n = 7 scans). In 32 of 36 PET scans, a dynamic acquisition was performed. Fifteen scans in 15 patients were performed to assess newly diagnosed les...

Abstract Purpose This study aims to investigate difference between magnetization-prepared rapid gradient-echo imaging (MPRAGE) and spin-echo (SE) imaging for evaluating glioma on pre-contrast-enhanced (CE) and post-CE T1-weighted images at 3 T. Materials and methods We retrospectively assessed pre-CE and post-CE T1-weighted images for tumor contrast in 64 consecutive glioma patients. Results In the nonenhancing tumors, the contrast was significantly clearer in MPRAGE than SE. In the enhancing tu...

Diffuse intrinsic pontine glioma is the most common brainstem tumor in pediatric patients. This tumor remains one of the most deadly pediatric brain tumors. The diagnosis primarily relies on clinical symptoms and imaging findings. Conventional MRI provides a noninvasive accurate method of diagnosis of these tumors. Advanced MRI techniques are becoming more widely used and studied as additional noninvasive methods to assist clinicians in initial diagnosis and staging, monitoring disease, as well ...

Abstract Objective This study examined the use of positron emission tomography (PET) ratios to improve the diagnostic ability of 18F-FDG PET/computed tomography (CT) in the differentiation of enhancing brain metastases, central nervous system lymphomas, and gliomas. Materials and methods Seventy-six patients with malignant brain tumors and available magnetic resonance imaging and PET/CT examinations were included. Results Among standardized uptake value (SUV)-related parameters tested, tumor max...

Aim of the Study: This study was to analyze the clinical outcomes of brain stem glioma treated with radiation therapy (RT) in our institution. Material and Methods: Records of 48 patients with brainstem glioma treated between January 2007 and January 2013 were reviewed. Demographic variables, clinical variables, radiological findings and treatment details with respect to age, sex, location of tumor ( pontine Vs non pontine ), signs and symptoms, RT dose, follow up period and outcomes were record...

We evaluated the diagnostic value of static and dynamic O-(2-[(18)F]fluoroethyl)-L-tyrosine ((18)F-FET) PET parameters in patients with progressive or recurrent glioma.We retrospectively analyzed 132 dynamic (18)F-FET PET and conventional MRI scans of 124 glioma patients (primary World Health Organization grade II, n = 55; grade III, n = 19; grade IV, n = 50; mean age, 52 ± 14 y). Patients had been referred for PET assessment with clinical signs and/or MRI findings suggestive of tumor progressio...

Abstract Brainstem gliomas (BSGs) are uncommon in adults accounting for about 2% of all intracranial neoplasms. They are often phenotypically low-grade as compared to their more common paediatric counterparts. Since brainstem biopsies are rarely performed, these tumours are commonly classified according to their MR imaging characteristics into 4 subgroups: (a) diffuse intrinsic low-grade gliomas, (b) enhancing malignant gliomas, (c) focal tectal gliomas and (d) exophytic gliomas/other subtypes. ...

Objectives To assess variability of the average standard uptake value (SUV) computed by varying the number of hottest voxels within an 18F-fluorodeoxyglucose (18F-FDG)-positive lesion. This SUV metric was compared with the maximal SUV (SUVmax: the hottest voxel) and peak SUV (SUVpeak: SUVmax and its 26 neighbouring voxels).

I gliomi del tronco cerebrale sono tumori rari dell’adulto (1-2% di tutti i gliomi) e costituiscono un gruppo eterogeneo. Negli adulti, predomina il sottotipo di basso grado, il che probabilmente spiega la loro prognosi migliore rispetto a quelli dei bambini. Data la rarita delle biopsie nell’adulto in questa localizzazione, sono state proposte classificazioni basate sull’aspetto radiologico, per stabilire strategie terapeutiche e definire sottogruppi prognostici (a basso grado intrinseco diffus...
