Lung Nodule Detectability on Computed Tomography at Ultra-low Dose Scanning with Adaptive Iterative Dose Reduction Using Three Dimensional Processing (AIDR3D): Comparison with Low-dose Scanning by Receiver-operating Characteristic Analysis
Yukihiro Nagatani MD et al.

DATE: Tuesday
TIME: 10:50 – 11:00 AM
Location: S404AB
PURPOSE:
To compare lung nodule detectability (LND) on computed tomography (CT) with adaptive iterative dose reduction using three dimensional
processing (AIDR3D) between ultra-low dose CT scanning (ULDS) and low dose CT scanning (LDS)
【コメント】
超低線量胸部CTの国内マルチセンタースタディの報告だそうです。肺がんCT検診の低線量化に重要なエビデンスとなるのではないでしょうか。

Scientific Formal (Paper) Presentations
Computer-aided Detection for Laxative-free Non-cathartic CT Colonography: Standalone Performance in a Screening Population
Janne J Nappi PhD et al.

DATE: Wednesday
TIME: 11:30 – 11:40 AM
Location: E351
PURPOSE:
To evaluate the standalone detection performance of a fully automated computer-aided detection (CAD) scheme in a laxative-free (non-cathartic) CT colonography (lfCTC) screening population.
【コメント】
検査目的により前処置を変える必要があるように、当然CADも変えていく必要があると思います。
