PY - 2017 T2 - Nuclear Cardiology: Practical Applications, 3e AB - The introduction of electrocardiographic (ECG)-gated myocardial single-photon emission computed tomography (SPECT) in the 1990s expanded the application of myocardial perfusion imaging to routinely include the assessment of LV systolic function.1 The development and use of this technique occurred when technetium-based imaging agents were placed into clinical use as these tracers provided much higher counts, and therefore image quality for measuring function. This was a critical development in the evolution of myocardial perfusion imaging. Currently, the majority of myocardial perfusion studies performed in the United States use gated SPECT technology and Tc-99m tracers. A more recent development has been the evaluation of ventricular dyssynchrony by SPECT, providing further data beyond myocardial perfusion. This chapter will discuss both aspects of ventricular assessment. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/29 UR - accesscardiology.mhmedical.com/content.aspx?aid=1145443790 ER -
