Aims Although cardiac hybrid imaging, fusing single-photon emission computed tomography (SPECT) myocardial perfusion imaging with coronary computed tomography angiography (CCTA), provides important complementary diagnostic information for coronary artery disease (CAD) assessment, no prognostic data exist on the predictive value of cardiac hybrid imaging. Hence, the aim of this study was to asse...
The main focus of this work is the reconstruction of the signals f and gi, i = 1, . . . , N , from the knowledge of their sums hi = f + gi, under the assumption that f and the gi’s can be sparsely represented with respect to two different dictionaries Af and Ag . This generalizes the well-known “morphological component analysis” to a multi-measurement setting. The main result of the paper state...
BACKGROUND AND OBJECTIVE: Nuclear medicine specialty based on the imaging of various organ functions has progressed in recent years with the improvement of imaging techniques towards hybrid imaging requiring knowledge of cross sectional anatomy. On the other hand, with the passing of time, most of knowledge of anatomy has been forgotten. METHODS: This study was conducted in an experimental stud...
The purpose of our study was to determine the value of different hybrid imaging combinations for the detection of focal and diffuse bone marrow infiltration in lymphoma. Patients with histologically proven lymphoma, who underwent both [18F]-FDG-PET/CT and whole-body MRI (including T1- and diffusion-weighted [DWI] sequences) within seven days, and a subsequent bone marrow biopsy, were retrospect...
Hybrid nanomaterial based on quantum dots and SWCNTs is used for cellular imaging and photothermal therapy. Furthermore, the ligand conjugated hybrid system (FaQd@CNT) enables selective targeting in cancer cells. The imaging capability of quantum dots and the therapeutic potential of SWCNT are available in a single system with cancer targeting property. Heat generated by the system is found to ...
