Preclinical imaging with SPECT combined with CT or MRI is used more and more frequently
and has proven to be very useful in translational research. In this article, an overview of …

Small-animal SPECT systems with stationary detectors and focusing multiple pinholes can
achieve excellent resolution–sensitivity trade-offs. These systems are able to perform fast total…

Ordered subsets expectation maximization (OSEM) is widely used to accelerate tomographic
reconstruction. Speed-up of OSEM over maximum likelihood expectation maximization (…

Cardiac parameters obtained from single-photon emission computed tomographic (SPECT)
images can be affected by respiratory motion, image filtering, and animal positioning. We …

Background In single-photon emission computed tomography (SPECT), attenuation of
photon flux in tissue affects quantitative accuracy of reconstructed images. Attenuation maps …

Pre-and intraoperative diagnostic techniques facilitating tumor staging are of paramount
importance in colorectal cancer surgery. The urokinase receptor (uPAR) plays an important role …

Cereceda A. Cardiac outflow of endothelin, neuropeptide Y and noradrenaline in relation to
hyperemia in coronary sinus flow following electrical conversion of induced ventricular …

Background Everolimus, a novel proliferation inhibitor and immunosuppressive agent, may
suppress cardiac-allograft vasculopathy. We conducted a randomized, double-blind, clinical …

The existing testing method could not accurately detect the defects in inner cavity with ant-nest
structure in a part. The reasons are as follows: the shape of inner cavity is irregular, the …

Macromolecule sequence, structure, and function are inherently intertwined. While well-established
relationships exist in proteins, they are more challenging to define for synthetic …
