Optimising central venous catheter placement by comparing cavoatrial junction position to chest X‐ray landmarks: A cross‐sectional study using CT chest reconstruction

Central venous catheter (CVC) tip placement guided by chest X-ray (CXR) landmarks is currently prone to inconsistency and malpositioning. This study aims to better define the relationship between the cavoatrial junction (CAJ) and selected X-ray landmarks.
