MRIMachine learningTexture analysisGLCMLBPAccurate vertebra detection and segmentation are essential steps for automating the diagnosis of spinal disorders. This study is dedicated to vertebra alignment measurement, the first step in a computer-aided diagnosis tool for cervical spine trauma. Automated ...

Spontaneous amygdala activity and functional connectivity were assessed during resting-state functional MRI. A brief battery of standardized neuropsychological tests was admi- nistered outside of the MRI scanner to assess three domains of cognitive function: executive functions, psychomotor speed, and ...

Is there a need for contrast-enhanced T1-weighted MRI of the spine after inconspicuous short tau inversion recovery imaging? Eur Radiol 2005; 15: 1387-1392Mahnken AH, Wildberger JE, Adam G et al (2005) Is there a need for contrast-enhanced T1-weighted MRI of the spine...
All MRI experiments were performed on a 3.0T clinical MR scanner (Magnetom Trio scanner, Siemens Medical Solutions, Erlangen, Germany) employing 8-channel phased array receiver spine coil (body coil was used as the transmitter). 3D-T1ρ-weighted sagittal images were acquired with a 3D GRE ...
In routine clinical practice, SC changes are well depicted using conventional MRI, especially T2-weighted imaging. However, this modality usually fails to provide satisfactory clinico-radiological correlations. In this context we assessed the potential value of quantitative changes measured with a T1 MP...
All subjects received standard T2-weighted MRI of the cervical spine (including SCS-grading 0-III), electrophysiological and clinical examinations.RESULTS: Patients revealed significantly decreased T1 relaxation times of the compressed spinal cord within the SCS (912鈥 扁53鈥痬s, mean鈥 扁standard ...
