Zhongshan Hospital is a comprehensive teaching hospital affiliated with Fudan University, handling more than 3,800,000 walk-in patients and emergency visits, 130,000 outpatients and 84,000 inpatients in 2016.
The Cardiology Department of Zhongshan Hospital is regarded as the most established and respected among general hospitals in China. We perform approximately 4,000 coronary intervention procedures every year with a success rate of above 98%. We installed the latest generation of D-SPECT cardiac imaging system in early 2017 to meet the increasing needs and demands of cardiologists.
Based on our experience with A-SPECT over the years, D-SPECT is indeed a breakthrough innovation with a great deal of improvement in many aspects including efficiency, accuracy, patient safety.
Image quality from A-SPECT is compromised due to limitation of technology. D-SPECT on the other hand, is definitely a state-of-the-art system that has successfully overcome the challenge of sensitivity and efficiency — it enables scan time reduction from 15 minutes (for A-SPECT) to 2 minutes.
Data collection of D-SPECT is not only efficient, but also precise; it serves as a very objective and accurate data for analysis. This helps us to overcome the challenge in false-positive findings in obese patients. The position of the heart in obese patients move significantly and this may lead to artifacts. D-SPECT utilizes BroadView technology for high speed data acquisition and an optimized algorithm for image reconstruction. The result provides a tremendous improvement in image quality (compared to A-SPECT), solving the clinical challenges for obese patients.
Last but not least, apart from myocardial perfusion imaging, D-SPECT enables us to perform coronary flow reserve (CFR) procedures. We conclude that this is a next generation of functional imaging that is irreplaceable by other imaging methods.
