Abstract
Aim of the work:to detect sensitivity of chest ultrasound versus high-resolution computed tomography (HRCT) chest in the diagnosis of peripheral lung lesions.
Background:Peripheral pleuropulmonary lesions vary from peripheral lung nodules,masses,effusion,consolidations and cavities,in addition to pleural nodules,pleural thickening and even lesions arise from chest wall.There were different imaging modalities to detect these lesions,so we aim to detect similarity and difference in detection of these lesions by both transthoracic ultrasound and high-resolution computed tomography (HRCT)chest.
Patients and methods:our study was done at our outpatient clinics,internal medicine department or department of chest diseases,Minia cardiothoracic university hospital,during the period from November 2022 to February 2024.The study included 60 patients subjected to have peripheral pleuro-pulmonary lesions in their chest x-ray,the lesions vary from pleural nodules,pleural thickening, peripheral soft tissue mass,peripheral pulmonary nodules, peripheral suspicious cavitary lesions and others. chest x-ray,HRCT chest and transthoracic ultrasonography were done to confirm lesions,we consider HRCT chest is the gold standard in our study,
Results: our results revealed that HRCT chest detected 27(45%) patients had mass lesion while transthoracic ultrasound detected 43% of studied patients with mass lesion with sensitivity of chest ultrasound of 85.2% and specificity of 90.9%. In comparison between HRCT chest and transthoracic ultrasound findings, there were no statistically significant between both of them as P was 0.76
Conclusion:there was no statistically difference between both of HRCT chest and transthoracic ultrasound in diagnosis of peripheral pleuropulmonary lesions with higher sensitivity of ultrasound in diagnosis of peripheral mass lesion in comparison with HRCT chest as a gold standard.
