5 Images were acquired using an investigational device.
6 In a clinical reader evaluation, the overall image quality and the image resolution were scored by two radiologists on a set of various exam types from 19 subjects. The images read contained one image acquired on the NaI unmodified device and the other on the new Discovery NM/CT 670 CZT, both acquired for the same duration. The CZT images were rated as good or better than the NaI images. Additionally, when the CZT acquisition datasets were adjusted to only use the first 75% of the total counts (equivalent to 75% of the acquisition time or with 25% less injected dose), the readers continued to rate all the images as diagnostic or higher (actual result will vary).
