Background/Aim:
This study aimed to compare high-resolution computed tomography (HRCT) findings with those of chest X-ray (CXR) and to evaluate the relationship of pulmonary function test (PFT) parameters with HRCT and CXR findings in cases of dental technician's pneumoconiosis.
Materials And Methods:
CXR, PFT, and HRCT data of 89 dental technicians who were diagnosed with pneumoconiosis were retrospectively evaluated.
Results:
The cases of 24 dental technicians (27%) classified as normal (Category 0) based on CXR were evaluated as Category 1 according to HRCT. There was an inverse correlation of PFT parameters with nodular profusion score in CXR and all HRCT parameters. In this participant sample, small opacities were predominant (70% of the individuals), and worsening of PFT parameters was associated with the prevalence of pulmonary parenchymal changes.
Conclusion:
In the present study, micronodules detected using HRCT had an effect on pulmonary function worsening, which has not been reported in previous studies.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
