Multi-Energy images will be compared to baseline Chest CT images for visualizing lung lesions, as determined. Expert readers will qualitatively evaluate the imaging differences (e.g. motion artifacts, technical defects, ease of anomalies identification, etc) with an evaluation form with a questionnaire grading system (i.e. 1 (severe defect), 2 (moderate defect) to 5 (no defect)).

Descriptive Information
Brief Title  ICMJE Feasibility of Multi-Energy Digital Radiography Detector for Lung Lesions Detection
Official Title  ICMJE Feasibility of Single Exposure Dual Energy Subtraction With a Multi-Energy Digital Radiography Detector for Lung Lesions Detection
Brief Summary A single-centre, industry sponsored, pilot study to assess the feasibility of Single Exposure Dual Energy Subtraction with a Multi-Energy digital radiography detector as an imaging platform for lung lesion detection.
Detailed Description

A feasibility study is proposed to investigate the imaging characteristics captured by a Single Exposure Dual-Energy Subtraction digital radiography with KA Imaging's Multi-energy detector.

The acquisition of Dual-Energy Subtraction radiography will consist of using the Multi-Energy detector integrated into the X-ray system in Grand River Hospital. Patient will receive a Multi-Energy Chest radiography exam on the same day as their routine chest CT exam. Each Multi-Energy radiography exam will consist of one Chest PA image and one Chest LAT image. Duration of each procedure is 60 minutes. The Multi-Energy Detector will generate a General Radiography Image and Dual-Energy Subtracted Images.

Visualization of lung lesions by Multi-Energy detector will be compared to corresponding CT exam and general radiography results. Imaging data will be evaluated qualitatively by radiologists on data collection form to describe the findings on the images. Further comparison between general radiography, Dual-Energy Subtraction radiography and CT will be analyzed to determine the differences of imaging characteristics such as description of image quality and visibility of relevant anatomical structures and anomalies.

Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Condition  ICMJE
  • Lung Tumor
  • Solitary Pulmonary Nodule
Intervention  ICMJE Device: Multi-Energy Digital Radiography Detector System
A Multi-energy digital flat panel detector for Single Exposure Dual-Energy Subtraction radiography is developed to capture x-ray images with improved tissue differentiation. Tissue-selective images can be produced at various tissue levels such as bone and soft tissue to visualize obscured anomalies that are not apparent to General Radiography.
