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.
