  2. 1. Assessment of Renal Physiology Using Functional MRI

    Author : Per Eckerbom; Per Liss; Fredrik Palm; Peter Hansell; Jarl Jakobsen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney; Renal; MRI; Phase contrast; ASL; BOLD; DWI; T1; COVID-19; Radiology; Radiologi;

    Abstract : Kidney injury is a major cause of morbidity and mortality throughout the world, leading to substantial individual suffering and to a heavy financial burden for the society. A large number of common conditions such as diabetes, hypertension, autoimmune diseases and infections are highly associated with kidney injury. READ MORE

  4. 2. 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

  5. 3. PET and MRI of Prostate Cancer

    Author : Catrin von Below; Håkan Ahlström; Cecilia Wassberg; Mauritz Waldén; Jens Sörensen; Michael Häggman; Joel Kullberg; Katrine Åhlström Riklund; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; lymph nodes; lymph node staging; PET CT; MRI DWI; extended pelvic lymph node dissection; targeted biopsies; multi-parametric MRI; TRUS guided biopsy; multiple regression analysis;

    Abstract : Prostate cancer (PCa) is the most common non-skin malignancy of men in developed countries. In spite of treatment with curative intent up to 30-40% of patients have disease recurrence after treatment, resulting from any combination of lymphatic, hematogenous, or contiguous local spread.

    Abstract : Diffusion-weighted imaging (DWI) is a very useful tool for non-invasive imaging and clinical investigation of the human body. It provides data of the water diffusion process. READ MORE

  7. 5. Whole-Body MRI including Diffusion-Weighted Imaging in Oncology

    Author : Firas Mosavi; Håkan Ahlström; Lennart Blomqvist; Uppsala universitet; []
    Keywords : Diffusion-weighted imaging; Whole-body MRI; NaF PET CT; FDG PE CT; apparent diffusion coefficient;

    Abstract : Cancer is one of the major causes of worldwide mortality. Imaging plays a vital role in the staging, follow-up, and evaluation of therapeutic response in cancer patients. Whole-body (WB) magnetic resonance imaging (MRI), as a non-ionizing imaging technique, is a promising procedure to assess tumor spreading in a single examination. READ MORE
