简要总结
Diagnostic accuracy study to investigate the sensitivity and specificity of sonographic elastography using strain ratio to differentiate between benign and malignant peripheral lesions in comparison to biopsy, clinically, or radiologically.
详细描述
This is a diagnostic accuracy study with comparison to gold standard tests e.g., chest computed tomography, transthoracic biopsy, or microbiological analysis. All patients included in this study will give informed consent according to the guidelines of ethics committee, Alexandria Faculty of Medicine.
