Article Title: Adaptive Iterative Dose Reduction Algorithm in CT: Effect on Image Quality Compared with Filtered Back Projection in Body Phantoms of Different Sizes

doi: 10.3348/kjr.2014.15.2.195

Figure Lengend Snippet: CT image of module 1 of 40-cm phantom reconstructed with adaptive iterative dose reduction three-dimensional standard mode at tube current time product of 180 mAs, showing alignment line (arrows).

Article Snippet: When AIDR 3D is used together with the automatic dose-modulation program ( SURE Exposure controls 3D, Toshiba Medical Systems Corporation), it may simplify the workflow and theoretically it is less concerned with image smoothing together with radiation-dose reduction ( ).

Figure Lengend Snippet: A contrast-enhanced CT image obtained with ASiR-V ( a ) and DLIR-H ( b ) showing the same hypoattenuating metastasis, magnified in the right lower corner (white arrows). Both readers detected the lesion on DLIR-H and missed the diagnosis on ASiR-V, as did a third independent reader.

Figure Lengend Snippet: A contrast-enhanced CT image obtained with ASiR-V ( a ) and DLIR-H ( b ) showing the same hypoattenuating metastasis, magnified in the right lower corner (white arrows). Both readers detected the lesion on DLIR-H and missed the diagnosis on ASiR-V, as did a third independent reader. The artifact reduction provided by DLIR can be seen in this example with osteosynthesis material artifact near the lesion significantly reduced. CT image of the same patient 18 months earlier before systemic treatment confirms lesion malignancy ( c )
