2. 1. Applications of diffusion MRI: Tensor-valued encoding, time-dependent diffusion, and histological validation

   Author : Jan Brabec; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diffusion MRI; meningioma; glioma; brain tumors; intracranial tumors; undulations; restricted diffusion; time dependence; spherical b-tensor encoding; linear b-tensor encoding; histogram analysis; anisotropic kurtosis; isotropic kurtosis; hyperintensity; conspicuity; white matter; detection; diffusion spectrum; consistency; type; grade; axon diameter; axonal trajectories; Fysicumarkivet A:2022:Brabec;

   Abstract : Diffusion MRI (dMRI) sensitizes the MR signal to the diffusion of water molecules at the microscopic level and thereby non-invasively probes tissue microstructure. This is relevant when determining biological properties of tissues, for example, cancer type and its malignancy. READ MORE

4. 2. Towards Novel Biomarkers for Low-grade Glioma

   Author : Shala Ghaderi Berntsson; Anja Smits; Peter Siesjö; Uppsala universitet; []
   Keywords : Low-grade glioma; prognosis; epilepsy; PROX1; DNA repair enzyme; PET; Physiological MRI; Neuroscience; Neurovetenskap;

   Abstract : Gliomas are common primary brain tumours that occur as low-grade (LGG) and high-grade gliomas (HGG). Typically occurring in younger adults, LGG has an indolent course with a median survival of 5-10 years, but carries an inherent potential for transforming into HGG. READ MORE

5. 3. Towards new tools for clinical evaluation and visualization of tumor growth in patients with glioma

   Author : Kenney Roy Roodakker; Anja Smits; Anne-Marie Landtblom; Elna-Marie Larsson; Jan J. Heimans; Uppsala universitet; []
   Keywords : PROX1; Histology; MRI; PET; Epilepsy; Co-registration; Neurology; Neurologi;

   Abstract : Gliomas are derived from glial cells and are the most common type of primary brain tumors in adults. Gliomas are classified by the World Health Organization (WHO) according to their malignancy grade and histological and molecular features. Malignancy grades range from I to IV. WHO grade I tumors are benign tumors, mostly occurring in childhood. READ MORE

6. 4. Novel treatments of glioblastoma in experimental models

   Author : Karolina Förnvik; Neurokirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Experimental glioma models; Glioblastoma; Complement system; C1 esterase inhibitor; ITPP; CRP; Glioma cells;

   Abstract : One of the major problems with malignant brain tumours, such as glioblastoma multiforme, is that despite being able to remove the major bulk of the tumour through surgery and treating the patients with chemotherapy and radiotherapy, we know that tumour cells have already spread throughout the brain. Furthermore, we now know that the glioblastoma cells effectively suppress the patients’ own anti-tumour response. READ MORE

7. 5. Deep Learning Methods for Classification of Glioma and its Molecular Subtypes

   Author : Muhaddisa Barat Ali; Chalmers tekniska högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 1p 19q codeletion; generative adversarial network; convolutional neural network; glioma subtype classification; IDH mutation.; Deep learning; cycleGAN; convolutional autoencoder;

   Abstract : Diagnosis and timely treatment play an important role in preventing brain tumor growth. Clinicians are unable to reliably predict LGG molecular subtypes from magnetic resonance imaging (MRI) without taking biopsy. Accurate diagnosis prior to surgery would be important. READ MORE
