متن کاملCLINICAL INVESTIGATIONS Poststress Motionlike Artifacts Caused by the Use of a Dual-Head Gamma Camera for 201Tl Myocardial SPECT
When performing 201Tl myocardial SPECT using a dual-head gamma camera on patients after exercise stress, we have observed in some a sudden increase in the counting rate between the 16th and 17th images. This increase provoked motionlike artifacts, which increased the number of false-positive findings. The aim of our study was to determine possible causes for this leap in activity. Methods: We p...

متن کاملElectronic off-peak status of one head of a dual-head gamma camera resulted in bone scintigraphy artifacts and faulty findings on gated myocardial SPECT.
OBJECTIVE Gamma cameras contain energy discriminators that allow only those photons within a specified energy range to be recorded. A spontaneous shift in peak of 1 head of a dual-head gamma camera may cause artifacts. We present our experience with the incidental occurrence of off-peak status in 1 head of a dual-head gamma camera that resulted in subsequent artifacts and poor-quality images. ...
متن کاملHead-to-head comparison of myocardial perfusion SPECT and CMR for assessment of myocardial ischemia
Background Myocardial perfusion single photon emission computed tomography (MPS) and cardiac magnetic resonance (CMR) can be used for assessment of myocardial ischemia. The methods reveal different aspects of the pathophysiology associated with myocardial ischemia where MPS is based on uptake of a perfusion tracer in viable mitochondria whereas CMR is based on firstpass perfusion reflecting cor...
