Abstract

International audience; We conducted a preclinical assessment on young macaques aimed at detecting white matter lesions. We present the protocol we implemented to achieve the lesions detection using a bedside non-invasive optical-based Time-Resolved instrumentation we have optimized for this purpose. We validated the reconstructed 3D absorption map with co-registration of MRI data. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

Abstract

A new approach to acquiring and analyzing small animal molecular imaging data is presented. By imaging the in-vivo dynamics of a dye or targeted probe, improved contrast and all-optical anatomical co-registration can be achieved.

Abstract

The dynamics of optical contrast agents are measured in an adenocarcinoma rat tumor model using a combined frequency-domain and steady-state optical technique. Compartmental modeling of contrast agent dynamics allows quantification of physiologic parameters such as capillary permeability and blood flow. Optically-derived parameters are compared to those measured by contrast-enhanced MRI.

Abstract

We studied the physiological changes in animal model tumors by co-registration of near-infrared spectroscopy and MRI. T2 weighted and Gd-DTPA enhanced MRI images correlate with changes observed in Hb, HbO2 and water concentrations measured by near-infrared spectroscopy.
