Brief Summary:
The main purpose of this study is to determine if PET-imaging can be used to evaluate inflammation level of intracranial aneurysms thus helping to evaluate the rupture risk of intracranial aneurysm
Detailed Description:
Study subjects are patients who are diagnosed with an unruptured saccular intracranial aneurysm and planned for elective surgical treatment of intracranial aneurysms Prior the planned surgery all study subjects will undergo PET-imaging of the brain with 18F-FDG- and 68Ga-DOTANOC-tracers targeting glucose metabolism and somatostatin receptors in inflammatory cells After PET-imaging samples for histopathological examination from the intracranial aneurysm sac will be collected during the surgery from every study subject Blood samples are collected prior to aneurysm operation from the routine pre-operative laboratory tests Cerebrospinal fluid samples are collected during the surgical procedure from the surgical site From blood samples we will evaluate expression of 20 different circulating microRNAs miRNA and the level of tumor necrosis factor-1 interleukin 1 beta vascular endothelial growth factor and evaluate correlations between miRNA expression and SUVmax in PET-imaging and miRNA and aneurysm histological findings
Correlation between inflammatory findings in histological studies and PET-imaging will be evaluated correlation of SUVmax to aneurysm histological findings
Correlation between inflammatory findings in histological studies and PET-imaging will be evaluated correlation of SUVmax to aneurysm histological findings
