2. 1. Quantitative Evaluation of Contrast Agent Dynamics in Liver MRI

   Author : Nils Dahlström; Örjan Smedby; Torkel Brismar; Anders Ynnerman; Carsten Thomsen; Linköpings universitet; []
   Keywords : Liver; spleen; hepatobiliary system; liver function; MRI; DCE-MRI; Gd-EOBDTPA; Gd-BOPTA; pharmacokinetic; hepatocyte; relaxivity.; MEDICINE; MEDICIN;

   Abstract : The studies presented here evaluate the biliary, parenchymal and vascular enhancement effects of two T1-shortening liver-specific contrast agents, Gd-BOPTA and Gd-EOB-DTPA, in Magnetic Resonance Imaging (MRI) of healthy subjects and of patients.Ten healthy volunteers were examined with both contrast agents in a 1.

4. 2. Fat-Referenced MRI : Quantitative MRI for Tissue Characterization and Volume Measurement

   Author : Thobias Romu; Magnus Borga; Olof Dahlqvist Leinhard; Samir Sharma; Linköpings universitet; []
   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

5. 3. Physical Aspects of Thermotherapy - A study of heat transport with a view to treatment optimisation

   Author : Johan Olsrud; Sektion V; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance; non-invasive; temperature; coagulation; prostatic; menorrhagia; liver tumour; finite element method FEM ; thermal conductivity; intracavitary; interstitial; laser; Thermotherapy; hyperthermia; MRI; Medicine human and vertebrates ; Medicin människa och djur ; Physics; Fysik; Fysicumarkivet A:1998:Olsrud;

   Abstract : Local treatment with the aim to destruct tissue by heating (thermotherapy) may in some cases be an alternative or complement to surgical methods, and has gained increased interest during the last decade. The major advantage of these, often minimally-invasive methods, is that the disease can be controlled with reduced treatment trauma and complications. READ MORE

6. 4. Mangafodipir trisodium (MnDPDP)-enhanced magnetic resonance imaging of the liver and pancreas

   Author : Chen Wang; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Liver; pancreas; neoplasms; metastases; endocrine tumor; MR imaging; contrast medium; mangafodipir trisodium; MnDPDP; manganese; Onkologi; Oncology; Onkologi; diagnostisk radiologi; Diagnostic Radiology;

   Abstract : Contrast-enhanced magnetic resonance imaging (MRI) of the liver and pancreas is frequently performed to improve the sensitivity and specificity of lesion detection in these organs. The concept of using tissue-specific contrast media is to selectively enhance the normal parenchyma, but not lesions, so that the contrast between tumorous and normal tissue is increased, and lesion detectability improved.

7. 5. Resection of colorectal liver metastases - Impact of preoperative chemotherapy

   Author : Sam Eriksson; Lund Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal liver metastases; Preoperative chemotherapy; Liver resection; Hepatic microcirculation; Sarcopenia;

   Abstract : Background Colorectal cancer is a leading cause of cancer related death worldwide. 20-30 % of patients will develop colorectal liver metastases (CRLMs). Surgical resection is the mainstay of treatment for CRLMs, and is often combined with perioperative chemotherapy, which can prolong progression-free survival after resection. READ MORE
