Volumetric measurement pulmonary ground-glass opacity nodules with multi-detector CT: effect of various tube current on measurement accuracy--a chest CT phantom study.

TL;DR: Study results indicate that routine protocols with reduced tube current are feasible with diagnostic results comparable to conventional standard dose protocols, and improvement in image production, especially the introduction of iterative reconstruction methods, is expected to lower radiation dose significantly.

TL;DR: The Veo reconstruction algorithms very effectively reduced image noise compared with the conventional FBP reconstructions and showed that GGOs can be detected and quantified with an acceptable accuracy.

TL;DR: Lung-nodule volumetry was extremely robust to the radiation-dose level, down to the minimum scanner-supported dose settings, which included both conventional filtered backprojection and iterative methods.

TL;DR: Computer-aided segmentation and mass and volume measurements of GGNs with the prototype software had promising results in this study and did not find significant differences in APE between CT scanners with filters for lower tube current for volume or lower tube voltage for mass.

TL;DR: In this article, the authors estimate the radiation-related cancer mortality risks associated with single or repeated full-body computed tomographic (CT) examinations by using standard radiation risk estimation methods.

TL;DR: Thin-section CT findings of peripheral lung adenocarcinomas correlate well with histologic prognostic factors and showed a significantly better prognosis than those with GGO components less than 50%.

TL;DR: About 75% of persistent pulmonary GGO nodules are attributed to BAC or adenocarcinoma with predominant BAC component, and at thin-section CT, these nodules do not manifest morphologic features that distinguish them from other G GO nodules with different histopathologic diagnoses.

TL;DR: An awareness of the clinical setting, in addition to familiarity with the thin-section CT features of nodular ground-glass opacity at initial and follow-up imaging over several months, can help identify malignancy and achieve an accurate diagnosis.
