High resolution chest CT (HRCT) and digital subtraction angiogram before and after the BAE in case #1. A 62-year-old male patient had history of intermittent hemoptysis for 30 years, became worse for one month with approximately 150 mL of blood each time. A-D: High resolution chest CT (HRCT) images showing reduced volume and uneven density in the right middle lobe as well as cavities and necrosis. E: Digital subtraction angiogram after selective catheterization of the right bronchial artery and super-selective catheterization with a microcatheter, showing hypertrophied artery and hyper-vascularity in the right middle lobe; F: Digital subtraction angiogram after embolization, demonstrating no residual flow to the lesion
