2. 1. Modern multimodal methods in brain MRI

   Author : David Abramian; Anders Eklund; Evren Özarslan; Ida Blystad; Hamid Behjat; Jesper Andersson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Functional MRI; Diffusion MRI; Graph signal processing; Deep learning;

   Abstract : Magnetic resonance imaging (MRI) is one of the pillars of modern medical imaging, providing a non-invasive means to generate 3D images of the body with high soft-tissue contrast. Furthermore, the possibilities afforded by the design of MRI sequences enable the signal to be sensitized to a multitude of physiological tissue properties, resulting in a wide variety of distinct MRI modalities for clinical and research use.

4. 2. Multidimensional MRI  of Myocardial Dynamics : Acquisition, Reconstruction and Visualization

   Author : Andreas Sigfridsson; Hans Knutsson; Sebastian Kozerke; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Cardiac motion; myocardial dynamics; strain; tensor; deformation; DENSE; k-t BLAST; Medical engineering; Medicinsk teknik;

   Abstract : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all rely on the quality of the measurements of heart dynamics. READ MORE

5. 3. Multidimensional MRI of Cardiac Motion : Acquisition, Reconstruction and Visualization

   Author : Andreas Sigfridsson; Hans Knutsson; Stefan Skare; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRI; cardiac; motion; reconstruction; Image analysis; Bildanalys;

   Abstract : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all benefit from improved methods of measuring the dynamics of the heart. READ MORE

6. 4. Volumetric MRI measurements of velocity and flow - Accuracy, visualisation and technical improvements

   Author : Anders Nilsson; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; 4D flow; phase contrast MRI; velocity mapping;

   Abstract : In the last two decades, phase-contrast magnetic resonance imaging (PC-MRI) has evolved from two-dimensional velocity and flow measurements to volumetric, time-resolved depictions of velocity fields (4D PC). The acquisition of time-resolved velocity fields allows flow visualisations that might provide better understanding of the dynamics of the cardiac system. READ MORE

7. 5. Preoperative MRI and PET in suspected low-grade gliomas : Radiological, neuropathological and clinical intersections

   Author : Anna Falk Delgado; Elna-Marie Larsson; Anja Smits; Jens Sörensen; John Hald; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Low-grade glioma; MRI; PET; FA; MD; Perfusion; Diffusion; Neuropathology; Oligodendroglioma; Astrocytoma; PET; tractography; DTI; DTT; Radiologi; Radiology;

   Abstract : Background: Gliomas are neuroepithelial tumours classified by cell type and grade. In adults, low-grade gliomas are comprised mainly of astrocytomas and oligodendrogliomas grade II. READ MORE
