Multimodality Imaging of Tumor Angiogenesis: Perfusion Modeling for Tumor Angiogenesis
When a tracer, such as Gd-doped or iodinated extracellular contrast, is introduced into the blood stream of a patient its transport through the vascular system, heart and lungs and eventual excretion via the kidneys is a well-established process [1,2]. At the level of the imaging voxel (for example, in the centre of a breast tumor) we can only speculate as to the precise nature of the tracer ki...
متن کاملMolecular Imaging of Tumor Angiogenesis
Molecular imaging has recently been defined by the Society of Nuclear Medicine as ‘the visualization, characterization, and measurement of biological processes at the molecular and cellular levels in humans and other living systems’ (Mankoff 2007). It usually exploits specific labeled molecular probes, as well as intrinsic tissue characteristics as the source of image contrast, and uses a numbe...
متن کاملRadionuclide imaging of tumor angiogenesis.
Angiogenesis is a multistep process regulated by pro- and antiangiogenic factors. In order to grow and metastasize, tumors need a constant supply of oxygen and nutrients. For growth beyond 1-2 mm in size, tumors are dependent on angiogenesis. Inhibition of angiogenesis is a new cancer treatment strategy that is now widely investigated clinically. Researchers have begun to search for objective m...
متن کاملF-18 FDG PET/CT imaging of primary hepatic neuroendocrine tumor
Primary hepatic neuroendocrine tumors (PHNETs) are extremely rare neoplasms. Herein, we report a case of a 70-year-old man with a hepatic mass. The non-contrast computed tomography (CT) image showed a low-density mass, and dynamic CT images indicated the enhancement of the mass in the arterial phase and early washout in the late phase. F18- fluorodeoxyglucose (18F-FDG) positron emission tomogra...
متن کاملTemporal and spectral imaging with micro-CT.
PURPOSE Micro-CT is widely used for small animal imaging in preclinical studies of cardiopulmonary disease, but further development is needed to improve spatial resolution, temporal resolution, and material contrast. We present a technique for visualizing the changing distribution of iodine in the cardiac cycle with dual source micro-CT. METHODS The approach entails a retrospectively gated du...
