1. 1. Colorectal Cancer Liver Metastases : Effects of Chemotherapy on Liver Parenchyma and Resections

   Författare :Jozef Urdzik; Agneta Norén; Per Hellman; James O Garden; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Current multimodal treatment of colorectal cancer liver metastasis often combines liver resections with preoperative chemotherapy with a 5-year survival of 40-50%. Preoperative chemotherapy includes conversion of initially non-resectable situation and control of micrometastatic disease. LÄS MER

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

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

   Sammanfattning : 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. 3. Liver tissue characterization and influence of chemotherapy in liver surgery

   Författare :Jan Nilsson; Lund Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal liver metastases; liver regeneration; incisional hernia; steatosis; hepatic microcirculation; diffuse reflectance spectroscopy; DRS; sidestream dark-field imaging; SDF; laser speckle contrast imaging; LSCI;

   Sammanfattning : Background & Aims: Primary liver cancer is the second most common cause of death from cancer worldwide. In the western world, the majority of liver malignancies consist of colorectal metastases. Liver resection is the primary treatment for cure in liver tumor disease. LÄS MER

5. 4. Methodological aspects on microdialysis sampling and measurements

   Författare :Pernilla Abrahamsson; Ola Winsö; Michael Haney; Anna-Maja Åberg; Urban Ungerstedt; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microdialysis; liver ischemia; heart ischemia; epicardium; liver parenchyma; CMA 600; metabolism; Anaesthetics and intensive care; Anestesiologi och intensivvård; anestesiologi; Anaesthesiology;

   Sammanfattning : Background:     The microdialysis (MD) technique is widely spread and used both experi­mentally and in clinical practice. The MD technique allows continuous collection of small molecules such as glucose, lactate, pyruvate and glycerol. Samples are often analysed using the CMA 600 analyser, an enzymatic and colorimetric analyser. LÄS MER

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

   Författare :Chen Wang; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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.
