Imaging of Chronic Thromboembolic Pulmonary Hypertension

CTEPH is an underdiagnosed but treatable condition, and radiologists play a critical role in improving patient care by recognizing CTED, particularly on CTPA. While chronic and acute pulmonary embolism have different imaging characteristics, distinguishing between the two can be challenging, especially when they coexist. Accurate imaging-based classification of CTEPH and identification of any additional pathology requiring surgical intervention are crucial in preoperative evaluation. Lastly, CTEPH has several mimics, but these conditions usually have distinct imaging features that help differentiate them.
