Acute pulmonary embolism (PE) with right ventricle (RV) enlargement and clot-in-transit. PE chest axial CT angiography images demonstrate pulmonary embolus in the right pulmonary artery (white solid arrow), an enlarged RV (dotted arrow), and thrombus transiting through the right atrium (black arrows), PE-RADS 4/RV+/T+. The “4” refers to the PE‑RADS ordinal category for the most proximal clot location (central arteries). “RV+” indicates RV enlargement (RV to left ventricle ratio ≥ 1.0). “T+” indicates definitive thrombus identified in the right atrium and/or RV.
