Value of attenuation correction in stress-only myocardial perfusion imaging using CZT-SPECT
BACKGROUND Attenuation correction (AC) improves the diagnostic outcome of stress-only myocardial perfusion imaging (MPI) using conventional SPECT. Our aim was to determine the value of AC using a cadmium zinc telluride-based (CZT)-SPECT camera. METHODS AND RESULTS We retrospectively included 107 consecutive patients who underwent stress-optional rest MPI CZT-SPECT/CT. Next, we created three t...
متن کاملCZT Support for Z Extensions
Community Z Tools (CZT) is an integrated framework for the Z formal specification language. In this paper, we show how it is also designed to support extensions of Z, in a way that minimises the work required to build a new Z extension. The goals of the framework are to maximise extensibility and reuse, and minimise code duplication and maintenance effort. To achieve these goals, CZT uses a var...
متن کاملCZT imaging detectors for ProtoEXIST
We describe the detector development for a balloon-borne wide-field hard X-ray (20 – 600 keV) telescope, ProtoEXIST. ProtoEXIST is a pathfinder for both technology and science of the proposed implementation of the Black Hole Finder Probe, Energetic X-ray Imaging Survey telescope (EXIST). The principal technology challenge is the development of large area, close-tiled modules of imaging CZT dete...
متن کاملEvaluation of myocardial perfusion and function after kidney transplantation by Gated SPECT myocardial perfusion scintigraphy
Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...
متن کاملMyocardial perfusion scintigraphy.
Myocardial perfusion scintigraphy (MPS) is the only widely available method of direct assessment of myocardial perfusion. It involves intravenous injection of small amounts of a radioactive tracer at peak stress, followed by imaging of the heart with a gamma camera. There are three commercially available tracers: thallium-201 and two technetium-labelled tracers, sestamibi and tetrofosmin. All t...
