  1. 1. Fat-Referenced MRI Quanitaive MRI for Tissue Characterizaion and Volume Measurement

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Thobias Romu; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; water-fat separation; quantitative MRI;

    Abstract : The amount and distribution of adipose and lean tissues has been shown to be predictive of mortality and morbidity in metabolic disease. Traditionally these risks are assessed by anthropometric measurements based on weight, length, girths or the body mass index (BMI). READ MORE

  4. 4. MRI assessment of haemophilic arthropathy

    University dissertation from Institutionen för kliniska vetenskaper, Lunds universitet

    Author : Björn Lundin; Lund University.; Lunds universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiologi; tomografi; medicinsk instrumentering; medical instrumentation; tomography; radiology; Clinical physics; Medicin människa och djur ; Medicine human and vertebrates ; Arthropathy; Factor VIII; Factor IX; MRI; Haemophilia; Klinisk fysiologi;

    Abstract : Haemophilia is a recessive genetic bleeding disorder in which coagulation time is prolonged due to the absence or malfunction of either of the serum proteins Factor VIII or IX. Joint destruction following repeated haemarthroses is the main cause of morbidity in haemophiliacs, and such arthropathy can be prevented or postponed by implementing prophylactic therapy with factor concentrate at an early age.

  5. 5. Quantitative Tracer Based MRI Perfusion Potentials and Limitations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Arvid Morell; Uppsala universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; Perfusion; Contrast agent; Relaxivity; Radiology; Radiologi;

    Abstract : Tracer based MRI perfusion measurements is a clinically useful tool to assess regional distributions of tissue blood flow and volume. The method may be based on any of the three relaxation mechanisms T1, T1 and T2*, the latter denoted DSC-MRI being the most common. READ MORE
