A Comparison of the Image Quality and Radiation Dose With Routine Computed Tomography and the Latest Gemstone Spectral Imaging Combination of Different Scanning Protocols in Computed Tomography Angiography of the Kidney.

Objective: The objective of our study was to compare the image quality and radiation dose of computed tomography angiography (CTA) of the kidney in patients with different body mass indexes using routine CT and the latest gemstone spectral imaging (GSI) combination of different scanning protocols with the adaptive statistical iterative reconstruction 2.0 algorithm.

Methods: A total of 90 patients who had undergone a CTA of the kidney were divided into 3 groups (A, B, and C), with 30 patients in each group.

CT Pulmonary Angiography Using Automatic Tube Current Modulation Combination with Different Noise Index with Iterative Reconstruction Algorithm in Different Body Mass Index: Image Quality and Radiation Dose.

Rationale And Objectives: This study aimed to determine the appropriate body mass index (BMI)-dependent noise index (NI) setting in computed tomography pulmonary angiography (CTPA) with automatic tube current modulation with adaptive statistical iterative reconstruction (ASiR).

Materials And Methods: A total of 480 patients who had a CTPA were divided into group A (18.5 kg/m ≤ BMI < 25 kg/m), group B (25 kg/m ≤ BMI < 30 kg/m), and group C (BMI ≥ 30 kg/m), according to their BMI values; each group had 160 patients.

A Comparison of the Image Quality and Radiation Dose Using 100-kVp Combination of Different Noise Index and 120-kVp in Computed Tomography Pulmonary Angiography.

Objective: The objective of our study was to compare the image quality and radiation dose of computed tomography pulmonary angiography (CTPA) in patients with different body mass indexes using 100-kVp combination of different noise indexes (NIs) and 120-kVp scan protocol with the adaptive statistical iterative reconstruction 2.0 algorithm (ASiR 2.0).
