Distinct peak at 3.8 ppm observed by 3T MR spectroscopy in meningiomas, while nearly absent in high-grade gliomas and cerebral metastases
(2012)The purpose of the present study was to evaluate distinct metabolic features of meningiomas to distinguish them from other brain lesions using proton magnetic resonance spectroscopy. The study was performed on 17 meningiomas, ... -
Neuroblastoma cells negative for CD44 possess tumor-initiating properties
(2011)CD44 has been linked to favorable prognosis in neuroblastoma and in the present study we investigate if it can be used to prospectively isolate neuroblastoma-initiating cells. To define the cancer-initiating properties of ... -
Prognostic Value of MRS Metabolites in Postoperative Irradiated High Grade Gliomas
(2015)Purpose. We studied the prognostic significance of Magnetic Resonance Spectroscopy (MRS) in operated high grade gliomas. Materials and Methods. Twelve patients were treated with radiotherapy and Temozolomide. The MRS data ... -
Proteomic Studies of Pediatric Medulloblastoma Tumors with 17p Deletion
(2015)CNS tumors are the leading cause of cancer-related death in children. Medulloblastoma is the commonest pediatric CNS malignancy, wherein, despite multimodal therapy with surgery, radiation, and chemotherapy, 5 year survival ... -
The role of diffusion and perfusion weighted imaging in the differential diagnosis of cerebral tumors: a review and future perspectives
(2014)The role of conventional Magnetic Resonance Imaging (MRI) in the detection of cerebral tumors has been well established. However its excellent soft tissue visualization and variety of imaging sequences are in many cases ... -
Spectroscopic Evaluation of Glioma Grading at 3T: The Combined Role of Short and Long TE
(2012)Purpose. To evaluate the diagnostic value of 3T H-1-MRS in grading cerebral gliomas using short and long echo times. Methods. (HMRS)-H-1 was performed on 71 patients with untreated cerebral gliomas. Metabolite ratios of ...
