Effects of different combinations of noise index and preset adaptive statistical iterative reconstruction Veo on the accuracy and image quality of bone mineral density measurements using fast kilovolt-switching dual-energy computed tomography: a phantom study.

ABSTRACT:

Background

Rapid kilovolt (kV)-switching dual-energy computed tomography (DECT) has been increasingly applied to the measurement of lumbar spine bone mineral density (BMD) in humans and animal models. The objective of this study was to investigate the optimal parameters for the measurement of vertebral BMD. The BMD of the spinal model was measured by means of DECT in combination with different noise index (NI) and preset adaptive statistical iterative reconstruction Veo (ASiR-V) levels. The results were verified through simulating diverse total adipose tissue (TAT) conditions.

Methods

A total of 54 sets of parameters, including NI ranging from 4 to 20 (at intervals of 2) and ASiR-V level ranging from 0% to 100% (20% increments), were used to perform rapid kV-switching DECT s
