Cancer patients are at a higher risk of developing blood clots, including pulmonary embolism. This heightened risk is due to several factors, such as the hypercoagulable state induced by the cancer itself, the effects of cancer treatments like chemotherapy, and prolonged immobility. Detecting a PE early can significantly improve the prognosis and guide appropriate management strategies. CTPA is considered the gold standard for diagnosing PE, making it invaluable in the clinical care of cancer patients.
