Difference Strain Ratio Ultrasound Elastography Between Benign and Malignant Peripheral Lung Lesions

Difference In Strain Ratio Ultrasound Elastography Between Benign And Malignant Peripheral Parenchymal Lung Lesions.

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.

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.

Inclusion Criteria:

• 1) Adult patients above age of 18 years old. 2) Patients with peripheral lung lesion.

Exclusion Criteria:

1. Pure pleural lesions.
