Clinical Trial Summary

The ULTRACHEST study will be a prospective clinical diagnostic performance study with primary objective to establish device diagnostic clinical performance of Ultra Low Dose CT (ULD-CT) in order to prove it is more accurate in detecting pneumonia when comparing to standard conventional chest radiography.


Clinical Trial Description

- 200 subjects

- Each subject will undergo CXR and ULD-CT at the same day.

- Subjects subdivided into 3 groups [high, moderate and low risk], based on a laboratory finding(CRP), symptoms and physical examination.

- 3 different thoracic radiologist will judge the scans on existence of consolidation. Consolidation will be expressed as binary outcomes (Yes or No consolidation)

- Radiologist will be blinded for subjects demographic data.

- All radiologist have to score how confidence they were on the finding of consolidation[5point likert].

- The investigators will perform a McNemar's test for evaluation. A two sided p-value of less than 0.05 will be considered to be statistically significant.

- Inter-observer variability will be evaluated by using a Fleiss Kappa test. ;
