Zhongshan Hospital Fudan University

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.

Clinique Pasteur (CIMOF) - Toulouse

Clinique Pasteur is an internationally renowned institution in the field of cardiology and the first French private hospital in the cardiology field with 462 beds and 170 MD’s.

The D-SPECT camera is installed in our institution since 2010. Thanks to the better sensitivity, improved image resolution and patient comfort provided by semi-upright position, our activity has increased from 4000 patients/year (with 2 cameras) to 6000 patients/year with only one D-SPECT camera and with a more accurate diagnostics.

The D-SPECT has increased the perfusion diagnostic quality of myocardial scintigraphy together with a functional study whose relevance proves to be an excellent prognostic marker for difficult patients, without sacrificing the comfort during the examination of these patients.

Clinique Saint-Augustin

CIF, Centre d’Imagerie Fonctionnelle, is a nuclear medicine department open since 2012, located at Saint-Augustin clinic, and where are performed scintigraphies.

The philosophy of our center is to respond as fast as possible to the demands of the cardiologists. The CZT technique made it possible to meet these demands with a shorter time of acquisition and excellent quality which is very important to meet the cardiologists needs and increase the number of patients scanned. With obese patients, we were able to carry out examinations under optimal conditions for the comfort of the patients as well as for the quality of the examination.

Our vendor selection was oriented by the small footprint of D-SPECT camera which was mandatory taking in account the restricted space available. In addition, the innovative armchair concept can be very important for better patient’s comfort.

The reliability of this product meets our expectations perfectly. To prove that, we have acquired a second machine.

Our practice has a 25 year history of providing high quality nuclear cardiology services in Richland County.  In 2015, we committed to making radiation dose reduction an equally high of priority as image quality.  Our multifaceted approach to radiation dose reduction included Appropriate Use Criteria (AUC), Body Mass Index (BMI) based dosing, and implementing a Selective Stress-Only imaging protocol.  We knew that count recovery software would not be enough to allow us to sufficiently lower radiation dose while still being able to meet the productivity demands of our department.  After months of camera evaluations and site visits, it became clear that the D-SPECT was going to be the key for us to meet our objectives.  In clinical practice, the D-SPECT has been paramount to enabling us to achieve our goal of acquiring the highest quality diagnostic images while simultaneously reducing radiation dose.

Our interpreting physicians have found the upright and supine imaging to be very beneficial in differentiating attenuation artifacts from true defects. Other manufacturers required CT attenuation correction or recommended prone imaging to minimize attenuation artifacts.  SPECT/CT for attenuation correction is very expensive and adds radiation dose to the patient.  Prone imaging is cumbersome and uncomfortable for most patients.  Our patients rave about the comfort of the D-SPECT.  The 542 pound weight limit also allows us to image very obese patients that we would have otherwise had to turn away if we were using any other system.  Our practice also utilizes the D-SPECT’s unique ability to perform dynamic SPECT to assess Coronary Flow Reserve (CFR).

The D-SPECT is a remarkable system that has exceeded our very high expectations.

Cancer Center of Santa Barbara

We’ve had our system for 10 years. It has truly revolutionized our patient experience. It is a very comfortable chair and with the short imaging time the patients love it! The independent cardiologists send us their patients rather than to the competitors in town because our image quality is exceptional with the D-SPECT® system. From a technical standpoint, once you get past the learning curve, it is a very easy system to use. The patient set up time is quick and simple and the processing time is quick too.

We love our D-SPECT so much, we traded it in this year on a brand new one with Dynamic SPECT capability.

Cardiovascular Center of Marin

D-SPECT turned 8 years old!

“The D-SPECT camera has been a rock, a pillar of strength,” said Dave Osborn, Supervisor of Nuclear Cardiology at Cardiovascular Center of Marin. We’re still really happy with it. Even after 8 years (our anniversary is this month) it is still hands-down the best camera I’ve ever worked with. It’s been like the Energizer Bunny. It’s hard to justify getting a new camera when the current D-SPECT continues to perform so well even after all these years.”

Cardiovascular Center of Marin delivers world-class care. Our fellowship-trained cardiologists are leaders in their fields and trained at some of the finest medical schools in the country. Our affiliation with Marin General Hospital provides access to the latest technologies and equipment, enabling our experts to perform a variety of innovative procedures. Services include education, prevention, state-of-the-art diagnostic services, advanced treatments and rehabilitation.

You list preventive cardiology as an area of expertise. What does this mean? 
Preventive cardiology is simply decreasing a person’s likelihood of having an adverse cardiac event such as a heart attack, stroke or cardiac arrest. However, like many things having to do with people and human biology, this is more complicated than it seems.
