Mnemonic for Chest X-ray in Heart Failure?,”A mnemonic to look for signs of heart failure on the CXR is ChECK, which stands for: – Cephalization (dilation of the pulmonary vessels radiating upward from the hilum due to fluid overload).- Effusions (look for blunting of the costophrenic angles).- Cardiomegaly (heart shadows occupying >50% of the thoracic diameter).- Kerley B lines (horizontal, peripheral white markings
especially at the bases).”
