    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MR studies; magnetic resonance MR ; 7 Tesla; T1 mapping; magnetization transfer saturation; Flip angle mapping; spoiled gradient echo; MR studies; magnetic resonance MR ; 7T; T1 mapping; magnetization transfer saturation; Flip angle mapping; spoiled gradient echo;

    Abstract : Quantitative MRI (qMRI) refers to the process of deriving maps of MR contrast parameters, such as relaxation times, from conventional images. If the qMRI maps have a high degree of precision and a low degree of bias, they can be compared longitudinally, across subjects, and (ideally) between measurement protocols and research sites.

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonance Imaging; UHF; MR safety; Patient compliance;

    Abstract : Background: More than 70 million magnetic resonance (MR) examinations are produced every year. Patients and personnel are exposed to electromagnetic fields at levels that exceed those normally found in our surroundings or in industry. READ MORE

  5. 3. Multiparametric MRI for evaluation of tumour treatment response : Studies of 177Lu-octreotate therapy of neuroendocrine tumour

    Abstract : Clinical assessment of tumour response to treatment largely relies on estimates of tumour size by, e.g., measuring the largest tumour diameters on magnetic resonance (MR) or computed tomography (CT) images, weeks or months after treatment. READ MORE
