Which SPECT for today, which SPECT for tomorrow?

Recent Advances in Nuclear Cardiology

“…1). The practical advantages of the CZT gamma camera compared to conventional gamma cameras are a high (up to 10 times higher) sensitivity and a moderately improved (2-3 times) spatial resolution, which are obtainable in a very short acquisition time (i.e., 2 min) ( Table 1) [7][8][9][10][11]. The high sensitivity is also attributed to the use of highly sensitive collimators (parallel-hole collimation with short collimator length and wide collimator inlet or cardio-focusing multi-pinhole collimation) in conjunction with the application of a resolution recovery algorithm [7].…”

“…The attenuation correction and scatter correction methods have been previously reviewed in the literature [18][19][20][21]. CZT cadmium-zinc-telluride Table 2 CZT-based gamma camera versus conventional scintillator-based gamma camera: scintillator is preferred to CZT [7][8][9][10][11] CZT Scintillator The application of resolution recovery methods has been a leap forward for the improvement of SPECT image quality. The resolution recovery algorithm is integrated into the iterative reconstruction process.…”

Improving Penetrance of Nuclear Medicine in India

“…In “lease” scenario, a center may opt for a more expensive machine such as a CZT camera and justify the excess expenditure in terms of savings on account of increased efficiency and reduced requirement of radiotracers. [ 4 ] In addition, radiation dose to the patient can be substantially reduced.…”
