Diagnostic Performance of a Novel Cadmium-Zinc-Telluride Gamma Camera System Assessed Using Fractional Flow Reserve

Clinical Feasibility of Simultaneous Acquisition Rest ^99mTc/Stress ²⁰¹Tl Dual-Isotope Myocardial Perfusion Single-Photon Emission Computed Tomography With Semiconductor Camera

“…14,21 Discordance in image interpretation was resolved by consensus. In this model, the left anterior descending coronary artery (LAD) territory consists of 8 segments (segments 1, 2, 5-7, 11, 12, 17), the left circumflex coronary artery (LCX) consists of 5 segments (segments 4, 9, 10, 15, 16) and the right coronary artery (RCA) consists of 4 segments (segments 3,8,13,14). Summed stress score (SSS), summed rest score (SRS) and summed difference score (SDS) were calculated as previously defined by Berman et al 22 Jeopardized myocardium was defined as SDS ≥2 in the relevant coronary vessels.…”

Cardiac Single-Photon Emission Computed Tomography Using Ultrafast Cadmium Zinc Telluride Gamma Camera With Thallium-201 Yields High-Diagnostic Performance Despite Lower Radiation Dose and Shorter Acquisition Time

“…10 This definition is reasonable and superior to a visual estimation of CAG only. These authors demonstrate that CZT SPECT using a smaller dose of thallium-201 with short acquisition time combined with prone imaging yields high diagnostic performance in detecting "significant" CAD.…”

“…Tanaka et al successfully eliminated this population from their investigation. 10 Every diagnostic test has advantages, disadvantages, and limitations. In addition, appropriate-use criteria for multimodality imaging in detecting CAG have been published, and a "choosing wisely campaign" is prevalent in the United States these days.…”

Role of Metabolic Imaging in Detecting Cardiac Involvement in Sarcoidosis

“…Comparing 123 I-BMIPP findings with the findings of active inflammation as determined through 18 F-FDG PET and those of tissue fibrosis as determined using 201 thallium myocardial perfusion imaging 13 or cardiac magnetic resonance imaging (CMR), it is apparent that 123 I-BMIPP findings may reflect the early phase of myocardial injury following the active inflammation phase (Figure). 123 Isolated CS, defined as sarcoidosis in patients lacking clinically apparent extracardiac disease, is difficult to detect because of the poor sensitivity of endomyocardial biopsy.…”
