Automated differentiation of glioblastomas from intracranial metastases using 3T MR spectroscopic and perfusion data
(2013)Purpose Differentiation of glioblastomas from metastases is clinical important, but may be difficult even for expert observers. To investigate the contribution of machine learning algorithms in the differentiation of ... -
Brain lesion classification using 3T MRS spectra and paired SVM kernels
(2011)The increased power and resolution capabilities of 3T Magnetic Resonance (MR) scanners have extended the reach of Magnetic Resonance Spectroscopy as a non-invasive diagnostic tool. Practical sensor calibration issues, ... -
Classification methods for the differentiation of atypical meningiomas using diffusion and perfusion techniques at 3-T MRI
(2013)The purpose was to investigate the contribution of machine learning algorithms using diffusion and perfusion techniques in the differentiation of atypical meningiomas from glioblastomas and metastases. Apparent diffusion ... -
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, ... -
Fast spectroscopic multiple analysis (FASMA) for brain tumor classification: a clinical decision support system utilizing multi-parametric 3T MR data
(2015)A clinical decision support system (CDSS) for brain tumor classification can be used to assist in the diagnosis and grading of brain tumors. A Fast Spectroscopic Multiple Analysis (FASMA) system that uses combinations of ... -
Focal therapy for prostate cancer: patient selection and evaluation
(2012)Recent stage migration toward low-risk prostate cancer, overtreament of biologically insignificant tumors with radical prostatectomy at the additional expense of a non-negligible morbidity and undertreatment of patients ... -
Frontal brain lobe impairment in obstructive sleep apnoea: a proton MR spectroscopy study
(2004)Patients with obstructive sleep apnoea syndrome frequently have cognitive deficits, especially related to executive functions, which cannot be fully explained by daytime sleepiness and are partial irreversible after nasal ... -
Implementation of physicochemical and sensory analysis in conjunction with multivariate analysis towards assessing olive oil authentication/adulteration
(2007)The authenticity of products labeled as olive oils, and in particular as virgin olive oils, stands for a very important issue both in terms of its health and commercial aspects. In view of the continuously increasing ... -
Investigating brain tumor differentiation with diffusion and perfusion metrics at 3T MRI using pattern recognition techniques
(2013)The aim of this study was to evaluate the contribution of diffusion and perfusion MR metrics in the discrimination of intracranial brain lesions at 3T MRI, and to investigate the potential diagnostic and predictive value ... -
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 ... -
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 ... -
Strengths and Weaknesses of 1.5T and 3T MRS Data in Brain Glioma Classification
(2011)Although magnetic resonance spectroscopy (MRS) methods of 1.5Tesla (T) and 3T have been widely applied during the last decade for noninvasive diagnostic purposes, only a few studies have been reported on the value of the ... -
Synovial fluid metabolites in osteonecrosis
(2007)Objectives. Osteonecrosis of the femoral head results from interruption of the vascular supply and eventual death of the cellular portion of bone. Effective methods of monitoring response to treatment are needed. Our aim ...
