“That is a remarkable difference in the visual appearance of the image,” Mendel explained. For 5 mm slice thickness, the best choice is the reconstruction method “iDose4-YA” for larger nodules (> 5 mm). Overall, “iDose4-YA” is suggested to achieve the best balanced results for both solid and GGO nodules. The results suggest that reconstruction methods “iDose4-STD” and “iDose4-YA” can be used for thin-slice and thick-slice, respectively, for different nodule types and sizes. 2.

Images from the standard examination were reconstructed with a hybrid iterative reconstruction method (iDose4), and images from the low-dose examinations were reconstructed with both iDose4 and IMR. Image quality was evaluated subjectively by three observers, according to modified EU image quality criteria, and evaluated objectively based on the noise observed in liver images. Philips provides two leading technologies that can improve image quality. iDose4* improves image quality* through artifact prevention and increased spatial resolution at low dose. O-MAR reduces artifacts caused by large orthopedic implants.

Objective image noise was significantly less using IMR than iDose4 (P < 0.0001).

The aim of this study is to evaluate the effect of iDose4 iterative reconstruction algorithm on radiation dose and imaging quality at chest–abdomen–pelvis (CAP) CT examinations. The end result is an image that looks more like traditional FBP. For example, compared to first-generation IR software, which had a 30 percent shift in the noise frequency spectrum, Philips’ current iDose4 AIM only has an 8-10 percent shift. “That is a remarkable difference in the visual appearance of the image,” Mendel explained.

ClariCT2 and iDose4 were also equivalent in artifact and lesion conspicuity scores. However, these two denoising techniques failed to show significant differences in artifact and lesion conspicuity compared with FBP, possibly due to heterogeneity of study population and lesions.
