in recent years, the development of neuroimaging techniques such as high-resolution magnetic resonance imaging (mri), functional magnetic resonance imaging (fmri), positron emission tomography (pet), or single photon emission tomography (spect) has promoted the identification of structural and functional characteristics underlying mental disorders to a great extent. in anxiety disorders, recent...

conclusions test-retest and correlation analyses have identified non-redundant radiomics features and this feature are prone to errors if they employed as quantitative biomarker for gbm image analysis. however when we use robust and redundant feature, quantitative image radiomics features are informative and prognostic biomarkers for gbm magnetic resonance imaging. results results shows that th...

OBJECTIVE To report MRI outcomes and explore the relationship between clinical remission and MRI inflammation in patients with axial spondyloarthritis (axSpA) from the RAPID-axSpA trial, including radiographic (r-)axSpA and non-radiographic (nr-)axSpA. METHODS RAPID-axSpA (NCT01087762) was double-blind and placebo-controlled to week 24, dose-blind to week 48 and open-label to week 204. Patien...

BACKGROUND AND PURPOSE Conventional MRI techniques do not necessarily provide information about multiple sclerosis (MS) disease pathology or progression. Nonconventional MRI techniques, including proton magnetic resonance spectroscopy (1 H-MRS), are increasingly used to improve the qualitative and quantitative specificity of MR images. This study explores potential correlations between MRI meas...

Background: The characteristic clinical presentation of glomus tumors and the low negative predictive value of themagnetic resonance imaging (MRI) raise the question whether MRI improves their management. Therefore, this studyaimed to investigate whether MRI improved the management of glomus tumors.Methods: In total, 87 patients with a histologically confirmed glomus tumor wer...

symptomatic laryngeal chondrometaplasia is rare. to the best of our knowledge, there are only few case reports on laryngeal chondrometaplasia. the imaging appearance of this uncommon disease is even more rarely described. there are only two case reports describing its appearances in computed tomography (ct) and magnetic resonance imaging (mri). ultrasound (us) features have not been reported so...

background: in this study the basic radiation properties of n-isopropylacrylamaide polymer gel dosimeter were determined together with verification of its soft tissue equivalency. materials and methods: the nipam gel was prepared and irradiated approximately 2 h after manufacturing. the magnetic resonance (mr) images were made 24 h after irradiation. the nuclear magnetic resonance (nmr) respons...
