Radiation Dose Consideration in Kidney Stone CT Examinations: Integration of Iterative Reconstruction Algorithms With Routine Clinical Practice

Abstract

The three IRs enable 20-33% radiation dose reduction in kidney stone CT examinations compared with the FBP technique without any image quality concerns. The radiation dose and image quality were comparable among these three IR algorithms.

Impact of Dose-Modified Protocols on Radiation Doses in Patients Undergoing CT Examinations following Image-Guided Catheter Placement

“…In agreement with previous studies focusing on the dose reduction capabilities of IRTs in the abdomen, the present study demonstrates dose reduction of 22% for follow-up CT examinations obtained with the use of IRT algorithms compared with conventional FBP examinations (15,18,19,22,31).…”

“…The cumulative dose following multiple DM follow-up CT examinations was 42% lower than the estimated CRD with SD protocols. The use of low-dose protocols for various CT examinations in the abdomen and published approaches for other abdominal examination types such as kidney stone examinations (22,28,29) were employed in catheter follow-up examinations reported in the present study.…”

“…Based on our previous experiences with the use of DM scan protocols for various indications, such as kidney stone follow-up CT examinations, we were able to modify protocols for catheter follow-up CT examinations (19,22,23). Scan acquisition parameters were determined by body Table 1.…”

Urinary Stone Disease: Advancing Knowledge, Patient Care, and Population Health

“…In addition to the cost of patient care associated with ultrasound and CT, the costs of training providers to use ultrasound and assuring their competency must be considered. Techniques to improve ultrasonography, including manipulating stones (65), as well as assessments of reduced dose radiographic approaches (66) are also key research opportunities in USD.…”

Does body mass index outperform body weight as a surrogate parameter in the calculation of size-specific dose estimates in adult body CT?

“…Further studies to assess the correlation between the parameters evaluated here and D w are desirable. Nevertheless, according to the AAPM report 220, it is reasonable to use geometric data to calculate SSDEs when D w is not available, and therefore D eff is frequently used for the calculation of SSDEs in clinical routine as well as in various recent studies investigating radiation dose exposure from CT. 10,[17][18][19] The number of wide-detector CT scanners is increasing. CTDI vol is calculated based on a 10-cm pencil chamber and therefore SSDEs might not be applicable on these scanners.…”
