4. 17. Magnetic resonance imaging of rectal tumours

   Author : Lennart Blomqvist; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Rectum; Neoplasms; Magnetic Resonance Imaging;

   Abstract : Cross sectional imaging techniques introduced during the last two decades have been increasingly used in the evaluation of patients with pelvic tumours. The extent of tumour - the tumour stage - at the time of diagnosis constitutes a guideline for both the immediate treatment and the follow-up of the patient. READ MORE

5. 18. Magnetic Resonance Imaging of the Heart : Image quality, measurement accuracy and patient experience

   Abstract : Background: Non-invasive diagnostic imaging of atherosclerotic coronary artery disease (CAD) is frequently carried out with cardiovascular magnetic resonance imaging (CMR) or myocardial perfusion single photon emission computed tomography (MPS). CMR is the gold standard for the evaluation of scar after myocardial infarction and MPS the clinical gold standard for ischemia. READ MORE

6. 19. Magnetic resonance imaging with ultrashort echo time as a substitute for X-ray computed tomography

   Author : Adam Johansson; Tufve Nyholm; Karlsson Mikael; James Balter; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic resonance imaging; computed tomography substitute; ultrashort echo time; parallel imaging; radial imaging; radiofysik; radiation physics;

   Abstract : Radiotherapy dose calculations have evolved from simple factor based methods performed with pen and paper, into computationally intensive simulations based on Monte Carlo theory and energy deposition kernel convolution.Similarly, in the field of positron emission tomography (PET), attenuation correction, which was originally omitted entirely, is now a crucial component of any PET reconstruction algorithm.

7. 20. Quantitative Muscle Composition Analysis Using Magnetic Resonance Imaging

   Author : Anette Karlsson; Magnus Borga; Anneli Peolsson; Janne West; Todd Parrish; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle Composition; Muscle fat Infiltration; Magnetic Resonance Imaging;

   Abstract : Changes in muscle tissue composition, e.g. decrease in volume and/or increase of fat infiltration, are related to adverse health conditions such as sarcopenia, inflammation, muscular dystrophy, and chronic pain. READ MORE
