Comparing Chest Ultrasound and CT in Differentiating Pleural Effusions

Sponsor: Assiut University

Summary

Pleural effusion is a condition where excess fluid builds up in the space between the lungs and the chest wall. To properly treat this condition, doctors must determine if the fluid is a "transudate" (usually resulting from systemic conditions like heart failure or liver disease) or an "exudate" (often resulting from local issues like infections, inflammation, or cancer). The standard method to classify this fluid involves inserting a needle into the chest to draw out a sample for laboratory testing, a procedure known as thoracentesis. While laboratory fluid analysis is highly accurate, the needle procedure carries some inherent procedural risks. This observational study aims to evaluate whether non-invasive imaging tests, specifically chest ultrasound and computed tomography (CT) scans, can accurately determine if the fluid is a transudate or an exudate. Researchers will enroll adult patients presenting with pleural effusion at Assiut University Hospital. As part of their diagnostic workup, participants will undergo a chest ultrasound, a chest CT scan and a standard diagnostic thoracentesis (fluid draw) within 24 to 48 hours of each other. The study will then compare the features seen on the ultrasound and CT scans against the laboratory fluid analysis (the current gold standard) to see how well the non-invasive imaging performs in identifying the specific type of pleural effusion.
