Methodological Aspects of Multicenter Studies with Quantitative PET

Quantification of whole-body FDG PET studies is affected by many physiological and physical factors. Much of the variability in reported standardized uptake value (SUV) data seen in the literature results from the variability in methodology applied among these studies, i.e., due to the use ...

FDG-PET/CT in Lymphoma

Molecular Imaging has played a prominent role in the assessment of lymphoma for now almost three decades since the introduction of 67Ga-citrate imaging for staging and restaging of both Hodgkin’s and non-Hodgkin’s lymphoma (HL and NHL). Since then other molecular probes have been investig ...

FDG PET Imaging of Head and Neck Cancers

In initial staging of head and neck cancers, the addition of FDG PET to conventional imaging improves the accuracy for cervical nodal metastases. The sensitivity of FDG PET is, however, limited in nodes

PET and PET-CT of Lung Cancer

Accurate staging is essential to offer the patient the most effective available treatment and the best estimate of prognosis. In non-small cell lung cancer (NSCLC), surgical resection offers the best chance of cure in the early stages, either alone or in combination with chemo- or radiotherapy ...

PET and PETCT in Esophageal and Gastric Cancer

Esophageal cancer ranks among the ten most common malignancies in the world and is a frequent cause of cancer-related death. Almost all therapeutic modalities for esophageal cancer are associated with considerable mortality and morbidity. Consequently, there has been growing conc ...

PET-CT in Radiotherapy for Lung Cancer

For NSCLC, F-18 FDG-PET scans allow more thorough staging, thus avoiding unnecessary treatments. It reduces radiation treatment volumes because of the avoidance of mediastinal lymph nodes that are PET negative and hence reduces toxicity with the same radiation dose or enables radiati ...

Shape and Volume of Living Aldosterone-Sensitive Cells Imaged with the Atomic Force Microscope

The steroid hormone aldosterone, which is synthesized in the suprarenal glands and secreted in response to a reduction in circulating blood volume, increases water and sodium reabsorption in the kidney (1,2). Although kidney is the major target organ, various other cell types, including d ...

Magnetic Resonance Microscopy: Concepts, Challenges, and State-of-the-Art

Recent strides in targeted therapy and regenerative medicine have created a need to identify molecules and metabolic pathways implicated in a disease and its treatment. These molecules and pathways must be discerned at the cellular level to meaningfully reveal the biochemical under ...

Mouse Morphological Phenotyping With Magnetic Resonance Imaging

The field of mouse phenotyping with magnetic resonance imaging (MRI) is rapidly growing, with both MRI physicists and biologists starting to use MRI to identify mouse models of human disease. The purpose of this chapter is to provide details of the animal handling necessary for routine and robu ...

Quantitative Perfusion Imaging Using Arterial Spin Labeling

MRI-based perfusion imaging techniques can be classified into those that use exogenously administered contrast agents and those that use an endogenous material that reflects blood flow. This chapter focuses on the technique of arterial spin labeling (ASL), in which endogenous water is ...

Magnetic Resonance Microscopy of Mouse Brain Development

Magnetic resonance imaging (MRI) is increasingly becoming an important tool to study anatomy of rodent brains. Compared with histology, it has clear advantages because the entire 3D object can be captured as an image nondestructively. However, low imaging resolution and a small number of a ...

Physiology of Functional Magnetic Resonance Imaging: Energetics and Function

Quantitative magnetic resonance spectroscopy (MRS) and imaging (MRI) measurements of energy metabolism (i.e., cerebral metabolic rate of oxygen consumption, CMRo2), blood circulation (i.e., cerebral blood flow, CBF; and cerebral blood volume, CBV), and functional MRI (fMRI) were us ...

Imaging Immunolabeled Drosophila Embryos by Confocal Microscopy

Monoclonal and polyclonal antisera raised against recombinant proteins are highly sensitive probes that reveal cellular and subcellular protein localization in developing embryos. For Drosophila researchers, the ease of generating such antisera (1) and the number and wides ...

Analyzing Morphogenetic Cell Behaviors in Vitally Stained Zebrafish Embryos

Owing to its extremely rapid rate of development, as well as its optical transparency, the zebrafish embryo provides an excellent experimental system for analyzing the cellular dynamics that underlie vertebrate body axis formation. Moreover, the zebrafish (Danio rerio) is very amen ...

Confocal Microscopy on Xenopus laevis Oocytes and Embryos

There are many problems affecting microscopy in Xenopus. Xenopus oocytes and embryos are fragile and lack connective tissue. They are also full of yolk platelets, which prevents frozen sectioning because the yolk crystallizes and tears the sections. In addition, the yolk autofluoresc ...

Confocal Imaging of Living Cells in Intact Embryos

How individual cells and tissues organize and coordinate to form the structure of a developing embryo is a major question in developmental biology. Equally intriguing is how cells in adult tissue respond during wound healing and tissue regeneration. In these morphogenetic processes th ...
