Direct thrombus imaging as a means to control the variability of mouse embolic infarct models: the role of optical molecular imaging.

I-55: Molecular Imaging Overview

Molecular imaging is the noninvasive visualization of normal as well as abnormal cellular processes at a molecular or genetic level of function. It is used to provide characterization and measurement of biological processes in living animals and humans (in vivo). The discipline of molecular imaging evolved rapidly over the past decade through the integration of cell biology, molecular biology a...

18F-FDG PET/CT in the diagnosis of tumor thrombus from anaplastic thyroid carcinoma in a young boy

  Anaplastic thyroid carcinoma is an uncommon, highly aggressive malignancy usually presenting in the elderly. An eighteen year old boy was recently diagnosed as anaplastic carcinoma of the thyroid.  PET/CECT scan performed for staging, revealed a large FDG avid heterogeneously enhancing thyroid mass with bilateral jugular venous thrombosis, which also showed increase...

Determination of experimental Tumor Volume of a mouse using optical imaging system in different processing stages

Applications of gold nanoparticles for medical imaging

Background & Aim: Molecular imaging enables us to non-invasively visualize tissue microstructures and lesion characterization, allowing accurate diagnosis of diseases at early stages. A successful molecular imaging requires a nontoxic contrast agent with high sensitivity. Nowadays, a wide range of nanoparticles have been developed as contrast agents for medical imaging modalities. Here, we revi...

Spectral Separation of Quantum Dots within Tissue Equivalent Phantom Using Linear Unmixing Methods in Multispectral Fluorescence Reflectance Imaging

Introduction Non-invasive Fluorescent Reflectance Imaging (FRI) is used for accessing physiological and molecular processes in biological media. The aim of this article is to separate the overlapping emission spectra of quantum dots within tissue-equivalent phantom using SVD, Jacobi SVD, and NMF methods in the FRI mode. Materials and Methods In this article, a tissue-like phantom and an optical...
