2. 1. Structural magnetic resonance imaging of bipolar disorder

   Author : Carl Johan Ekman; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Bipolar disorders are illnesses with recurring episodes of elevated or depressed mood. Although most affected individuals have periods when they are free of symptoms, they carry a life-long risk of relapse. The cause of the illness has not yet been established. READ MORE

4. 2. Magnetic Resonance Imaging in Parkinsons's disease and related disoders

   Author : Yulia Surova; Lund Neurologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mr Imaging; DTI; Parkinson s disease; Progressive supranuclear palsy; Multiple system atrophy;

   Abstract : Objectives: To identify diagnostic and prognostic biomarkers in the cerebral white (WM) and the deep grey matter (GM) in patients with Parkinson’s disease (PD) and atypical parkinsonian syndromes (APS) using magnetic resonance imaging (MRI). Methods: Patients with a clinical diagnosis of PD, multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) were included in the study. READ MORE

5. 3. Cancer imaging and image analysis methods in whole-body MRI and PET/MRI

   Author : Therese Sjöholm; Joel Kullberg; Filip Malmberg; Robin Strand; Håkan Ahlström; Einar Heiberg Brandt; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; diffusion weighted imaging; positron emission tomography; whole-body imaging; normal atlas; CAR T-cell therapy; lymphoma; medical image analysis; Computerized Image Processing; Datoriserad bildbehandling;

   Abstract : Diagnostic medical imaging techniques such as magnetic resonance imaging (MRI) and positron emission tomography (PET) can provide structural and functional assessments of the whole body. This has great value for potentially systemic diseases such as cancer. READ MORE

6. 4. Imaging of tissue degeneration in knee osteoarthritis using magnetic resonance and synchrotron radiation

   Author : Emma Einarsson; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging MRI ; osteoarthritis OA ; Meniscus; Chemical Exchange Saturation Transfer CEST ; Relaxation time; Synchrotron radiation X-ray tomographic microscopy;

   Abstract : Osteoarthritis (OA) is a very common disease, especially in the knee. It is characterized by the breakdown of articular cartilage but involves all parts of the joint. OA is usually diagnosed at a late stage when the articular cartilage has begun to disappear. What happens before these macroscopic alterations is to alarge extent unknown. READ MORE

7. 5. Temporal dynamics of brain plasticity : characterizing brain structural changes during skill acquisition

   Author : Tomás Mediavilla; Daniel Marcellino; Alexandra Badea; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; brain plasticity; structural plasticity; magnetic resonance imaging; voxel-based morphometry; tractography; connectivity; motor cortex; posterior parietal cortex; cerebellum; vesicular glutamate transporter;

   Abstract : Traditionally, structural plasticity in the human brain has been considered to follow a linear or asymptotic increase over the course of training. However, recent studies using structural MRI revealed transient increases in grey matter volume (GMV) with learning. READ MORE
