Standard dose versus low-dose abdominal and pelvic CT: comparison between filtered back projection versus adaptive iterative dose reduction 3D.
PURPOSE To compare the dose and image quality of a standard dose abdominal and pelvic CT with Filtered Back Projection (FBP) to low-dose CT with Adaptive Iterative Dose Reduction 3D (AIDR 3D). MATERIALS AND METHODS We retrospectively examined the images of 21 patients in the portal phase of an abdominal and pelvic CT scan before and after implementation of AIDR 3D iterative reconstruction. Th...
متن کاملPatient dose and image quality in low-dose abdominal CT: a comparison between iterative reconstruction and filtered back projection.
BACKGROUND In computed tomography (CT), there is increasing concern for potential CT radiation hazards. Several raw-data-based iterative reconstruction techniques attempt to facilitate low-dose imaging without compromising image quality, which raises the question whether these techniques may allow further dose reduction. PURPOSE To compare image quality of iterative reconstruction and filtere...
متن کاملReduced-dose low-voltage chest CT angiography with Sinogram-affirmed iterative reconstruction versus standard-dose filtered back projection.
PURPOSE To evaluate image quality of low-voltage chest computed tomographic (CT) angiography with raw data-based iterative reconstruction (sonogram-affirmed iterative reconstruction) in comparison with image quality of standard-dose standard-voltage filtered back projection (FBP) CT. MATERIALS AND METHODS This prospective study was approved by the institutional review board, and the informed ...
متن کاملIterative reconstruction in head CT: image quality of routine and low-dose protocols in comparison with standard filtered back-projection.
BACKGROUND AND PURPOSE IR has recently demonstrated its capacity to reduce noise and permit dose reduction in abdominal and thoracic CT applications. The purpose of our study was to assess the potential benefit of IR in head CT by comparing objective and subjective image quality with standard FBP at various dose levels. MATERIALS AND METHODS Ninety consecutive patients were randomly assigned ...

results the study consisted of 40 patients (all men, with mean age of 33.38 ± 7.4 years). ct evaluation with standard dose were positive in 22 patients (55%). only 1 (2.5%) ct scan assigned as unacceptable by each radiologist in low-dose group. noise average of low-dose protocol, was approximately 7 times greater than standard dose group, while dlp and ed are 9.7 times smaller. in comparison wi...
