This guideline is based on a comprehensive review of the literature on pulmonary nodules
and expert opinion. Although the management pathway for the majority of nodules detected …

The incidence of indeterminate pulmonary nodules has risen constantly over the past few
years. Determination of lung nodule malignancy is pivotal, because the early diagnosis of …

Purpose: The authors previously developed the 4D extended cardiac‐torso (XCAT) phantom
for multimodality imaging research. The XCAT consisted of highly detailed whole‐body …

OBJECTIVE. This article aims to summarize the available data on reducing radiation dose
exposure in routine chest CT protocols. First, the general aspects of radiation dose in CT …

OBJECTIVE. The purpose of this study is to assess the image quality and radiation dose
reduction of ultra-low-dose CT using sinogram-affirmed iterative reconstruction (SAFIRE) …

Computed Tomography (CT) is the mainstay of diagnostic imaging evaluation of thoracic
disorders. However, there are a number of CT protocols ranging from a simple non-contrast …

Computed tomography currently accounts for the majority of radiation exposure related to
medical imaging. Although technological improvement of CT scanners has reduced the …

Purpose We reviewed the clinical utility of perfusion (Q)-single-photon emission computed
tomography (SPECT)/CT for diagnosing pulmonary embolus (PE) in patients hospitalized …

Purpose Studies have evaluated imaging modalities with a lower radiation dose than
standard-dose CT (SD-CT) for chest examination. This systematic review aimed to …

OBJECTIVE. The aim of our study was to evaluate CT scanning protocols to determine how
best to minimize patient exposure to ionizing radiation while maintaining sufficient image …
