Low-dose thallium-201 protocol with a cadmium-zinc-telluride cardiac camera.
OBJECTIVES Thallium-201 is efficient for myocardial perfusion imaging, but leads to relatively high radiation exposure in patients. The purpose of this study was to compare the efficiency of low-dose thallium-201 imaging with cadmium-zinc-telluride (CZT) cameras with regular-dose thallium-201 imaging with conventional cameras. METHODS We prospectively studied 137 consecutive patients referred...
متن کاملElectric Field Distribution of Cadmium Zinc Telluride (CZT) Detectors
Cadmium Zinc Telluride (CZT) is attracting increasing interest with its promise as a room-temperature nuclear-radiationdetector material. The distribution of the electric field in CZT detectors substantially affects their detection performance. At Brookhaven National Laboratory (BNL), we employed a synchrotron X-Ray mapping technique and a Pockels-effect measurement system to investigate this d...
متن کاملThe Cadmium Zinc Telluride (CZT) Detector Array Innovation Pathway
This pathway describes the development of soft gamma-ray/hard x-ray detector arrays at NASA’s Goddard Space Flight Center (GSFC, or Goddard), through a collaboration between the gamma-ray spectroscopy group and the detector branch. The Cadmium Zinc Telluride (CdZnTe, or CZT) detectors which resulted from this decade-long development were first flown on the wildly successful SWIFT mission in 200...

متن کاملEvaluation of left ventricular diastolic function with a dedicated cadmium-zinc-telluride cardiac camera: comparison with Doppler echocardiography.
AIMS To evaluate the relationships between measures of left ventricular (LV) filling dynamics at cadmium-zinc-telluride (CZT) imaging and indexes of LV diastolic function at transthoracic echocardiography. METHODS AND RESULTS Two hundred and forty-seven patients underwent myocardial perfusion imaging at rest and after stress with a low-dose CZT protocol and a baseline transthoracic echocardio...
