Galbumin, a new blood pool agent, extravasates from tumour vasculature
Introduction Tumour tissue is highly heterogeneous and characterized by a vastly disordered vasculature along with severe deregulation of normal cell processes. While immuno-histological investigation of tumour vasculature is precise, there is an urgent clinical need to develop accurate, non-invasive imaging techniques to improve the characterization of tumor angiogenesis and the monitoring of ...

INTRODUCTION: Dynamic susceptibility contrast MRI (DSC-MRI) is a novel tool that has shown promise to increase the predictive power of diagnostic imaging, for example in the assessment of brain tumor grade [1]. Alterations in microvascular parameters such as blood volume and vascular permeability induced by pathological angiogenesis are detectable with DSC-MRI. However, the basic assumptions of...

Introduction: All of the Imaging modalities have advantages and disadvantages alone. So if we want to have the best and perfect image, combining these modalities produces something we desired. PET-MR images consist of morphologic and metabolic data. MRI and PET provide high spatial and contrast resolution and high sensitivity and molecular information respectively. Hybrid PET-...
