Mediastinal, hilar, and pleural image-guided biopsy: current practice and techniques

Area of Science:

• Radiology
• Interventional Radiology
• Diagnostic Imaging

Background:

• Cross-sectional imaging like CT and MRI precisely identifies mediastinal, hilar, and pleural abnormalities.
• Diagnosis and treatment planning for these conditions frequently rely on tissue sampling via biopsy.
• Current diagnostic pathways often necessitate invasive surgical procedures.

Purpose of the Study:

• To evaluate the efficacy and safety of image-guided biopsy for mediastinal, hilar, and pleural masses.
• To highlight the role of interventional radiology in minimally invasive tissue acquisition.
• To compare image-guided biopsy with traditional surgical methods.

Main Methods:

• Utilized computed tomography (CT) and ultrasonography for precise targeting of thoracic masses.
• Performed image-guided biopsies in an outpatient setting under local anesthesia and conscious sedation.
• Analyzed biopsy samples for diagnostic accuracy, sensitivity, and specificity.

Main Results:

• CT and ultrasonography demonstrated high sensitivity and near-perfect specificity in guiding biopsies.
• Minimally invasive biopsy procedures were associated with rare major complications and easily managed minor complications.
• Successful tissue sampling was achieved, providing crucial diagnostic information.

Conclusions:

• Image-guided biopsy is a highly sensitive and specific diagnostic tool for mediastinal, hilar, and pleural pathologies.
• Interventional radiology-guided biopsies offer a safe, effective, and minimally invasive alternative to surgical procedures.
• These techniques obviate the need for more invasive diagnostic interventions like thoracoscopy or mediastinoscopy.
