Metrics and textural features of MRI diffusion to improve classification of pediatric posterior fossa tumors.
BACKGROUND AND PURPOSE Qualitative radiologic MR imaging review affords limited differentiation among types of pediatric posterior fossa brain tumors and cannot detect histologic or molecular subtypes, which could help to stratify treatment. This study aimed to improve current posterior fossa discrimination of histologic tumor type by using support vector machine classifiers on quantitative MR ...
متن کاملDifferential diagnosis of posterior fossa brain tumors
This study investigated the combined capability of thallium-201 (Tl)-SPECT and fluorine-18-fluoro-deoxy-glucose (FDG)-PET for differential diagnosis of posterior fossa brain tumors using multiple discriminant analysis.This retrospective study was conducted under approval of the institutional review board. In the hospital information system, 27 patients with posterior fossa intra-axial tumor bet...
متن کاملThe Clinical Challenges of Pediatric Posterior Fossa Tumors
Pediatric brain tumors occur mainly in the posterior fossa. Clinicians encounter numerous difficulties and challenges in establishing the diagnosis. Symptomatology varies according to the location of tumor, its rate of progression, and the age of the child. Most of them are usually nonspecific and misinterpreted as common benign childhood disorders. Consequently, a significant delay arises betw...
متن کاملValue and limitations of diffusion-weighted imaging in grading and diagnosis of pediatric posterior fossa tumors.
DWI reportedly accurately differentiates pediatric posterior fossa tumors, but anecdotal experience suggests limitations. In 3 years, medulloblastoma and JPA were differentiated by DWI alone in 23/26 cases (88%). Ependymoma (n = 5) could not be reliably differentiated from medulloblastoma or JPA. A trend toward increased diffusion restriction in higher grade tumors (1/14 grade I, 7%; 9/12 grade...
متن کاملNeurocognitive late effects of pediatric brain tumors of the posterior fossa: a quantitative review.
Deficits in neurocognitive functioning are an important area of late effects in survivors of pediatric brain tumors; however, a quantitative analysis of the magnitude of these deficits in survivors of brain tumors of the posterior fossa has not been conducted. Despite tumor locations in the posterior regions of the brain, individual studies have documented deficits in a variety of domains, refl...
