A low radiation dose CT protocol without IV contrast is used in patients with renal stone disease who may need repeated CT examinations for follow up of treatment or surveillance. In this exam, the CTDIvol was 2 mGy, and axial images are reconstructed with both iDose 4 (4-mm [A, B]) and IMR (1-mm [C, D]). Philips offers a fourthgeneration IR solution called iDose 4.The solution is available on all levels of scanners from the Brilliance 64 to the iCT to the newly released Ingenuity CT, which has builtin iDose 4 capabilities.

In our clinical practice, three IR techniques—ASiR (GE Healthcare), iDOSE (Philips Healthcare), and SAFIRE (Siemens Healthcare)—have been in use and continue to be used. Designed to seamlessly integrate into your CT department, iDose4 improves image quality* with the look and feel of conventional images. iDose section CT scanner using the optimized scan and reconstruction (iDose) parameters combination determined from the cadaver and phantom studies. Axial and coronal reformations were created, and CNRmeasurementsconsistentwiththetechniqueusedpreviouslyin the study were performed.

Raw CT data of the study subjects were reconstructed using both standard FBP and hybrid IR (iDose; Philips Healthcare, Best, the Netherlands). iDose is a recently introduced reconstruction algorithm using two denoising components [3, 6, 8], which provides image …

In this exam, the CTDIvol was 2 mGy, and axial images are reconstructed with both iDose 4 (4-mm [A, B]) and IMR (1-mm [C, D]). Philips offers a fourthgeneration IR solution called iDose 4.The solution is available on all levels of scanners from the Brilliance 64 to the iCT to the newly released Ingenuity CT, which has builtin iDose 4 capabilities. iDose 4 provides flexibility in a novel way compared to other similarly marketed techniques as a result of its fourth-generation design. We conclude that iDose is an important tool in the reduction of radiation dose in CT. However, continuous efforts to reduce radiation dose should be pursued. View In addition, it is worth to note that the LDCT protocol combined with iDose 4 was practiced as reference standard instead of full-dose protocol with FBP reconstruction in our study, considering iDose 4, the hybrid IR, has already been used routinely with robust reconstruction speed, as well as the hybrid IRs such as iDose 4, sinogram-affirmed iterative reconstruction, and adaptive statistical iterative reconstruction … Conclusions: The iDose algorithm clearly demonstrates effectiveness in noise suppression over the FBP. The low-contrast detectability depends on noise but also on NPS, which is shifted by iDose algorithm. At very low-dose levels, greater iDose levels would be needed to reduce the image noise but may not improve the low-contrast detectability.

The Catphan® phantom was scanned at a fixed CT dose index volume (CTDI vol). Images were reconstructed with FBP as well as different levels of iDose4 and IMR. All parameters are shown in Table 1. Images were reconstructed with different slice thicknesses (1, 3, and 5 mm). Image noise (one standard deviation [SD] of the CT-numbers) was measured Dose reduction in children undergoing CT scanning is an important priority for the radiology community and public at large. Drawbacks of radiation reduction are increased image noise and artifacts, which can affect image interpretation. Iterative reconstruction techniques have been developed to reduce noise and artifacts from reduced-dose CT examinations, although reconstruction algorithm Khawaja R. et al, CT of Chest at <1 mSv: An Ongoing Prospective Clinical Trial of Chest CT at Sub-mSv Doses with IMR and iDose4, JCAT 2014;38: 613–619 Conclusions: Sub-mSv IMR improves delineation of lesion margins compared to standard-dose FBP and sub-mSv iDose4.
