Single- vs. dual-head SPECT for detection of myocardial ischemia and viability in a large study population

The effects of technological developments on nuclear medicine technologist productivity: A systematic review

“…Of the 1,233 titles and abstracts reviewed after duplicates were removed, 16 full text articles were accepted in the systematic review. Six studies reported on myocardial perfusion (2;11;14;19;43;53), two studies in information technology (36;37) and eight studies in PET (10;18;23;28;30;34;44;52). Supplementary Table 2, which can be viewed online at , displays the study characteristics and outcomes.…”

“…Four studies (11;14;43;53) fully report the acquisition parameters and the gamma camera system used. One study (19) reports only partial information.…”

“…Dual-detector systems acquire the study in almost half the time of single-detector systems if the same acquisition parameters are used. Acquisition time for dual-detector systems is reported by two authors (11;14) to be 21 minutes, whereas a single-detector system takes 43 minutes with the same acquisition time per projection and the same number of projections (11). The number of projections and time per projection will alter the total acquisition time.…”

“…The number of projections and time per projection will alter the total acquisition time. The reported acquisition times ranged from 20 to 50 seconds per slice (11;14;43;53). All papers effectively acquired 64 slices, leading to an overall time of 21–48 minutes.…”
