Robust MRI brain tissue parameter estimation by multistage outlier rejection.
This article addresses the problem of the tissue type parameter estimation in brain MRI in the presence of partial volume effects. Automatic MRI brain tissue classification is hampered by partial volume effects that are caused by the finite resolution of the acquisition process. Due to this effect intensity distributions in brain MRI cannot be well modeled by a simple mixture of Gaussians and t...
متن کاملTissue doppler echocardiography in the diagnosis of heart transplantation rejection.
BACKGROUND Endomyocardial biopsy (EMB) is the gold standard method for the diagnosis of cellular rejection (CR) after heart transplantation (HT). OBJECTIVE To test the hypothesis that tissue Doppler imaging (TDI) could detect CR > 3A and add diagnostic information compared to conventional Doppler. METHODS Fifty-four HT patients underwent 129 EMB and a TDI echocardiographic study within 24 h...
متن کاملSentinel Skin Allograft for Monitoring of Composite Tissue Transplants Rejection
In contrast to visceral solid-organ transplants, a vascularized composite tissue allograft (CTA) is not a single tissue, and is histologically heterogeneous. It is a neurovascularized module of nonvital tissues which include structural, functional and aesthetic units. CTAs are composed of a large spectrum of ectodermal tissues: epidermis and epidermal derivatives such as nails and hair, nerves ...
متن کاملTissue-specific exosome biomarkers for noninvasively monitoring immunologic rejection of transplanted tissue.
In transplantation, there is a critical need for noninvasive biomarker platforms for monitoring immunologic rejection. We hypothesized that transplanted tissues release donor-specific exosomes into recipient circulation and that the quantitation and profiling of donor intra-exosomal cargoes may constitute a biomarker platform for monitoring rejection. Here, we have tested this hypothesis in a h...
