Cho, MD INTRODUCTION The imaging modalities including ventilation-perfusion scan, computed tomography angiography (CTA), and magnetic resonance angiography (MRA) now provide much of the diagnostic information that can be derived from pulmonary angiography with less risk and at lower cost.1,2,3,4,5 At the same time the number and variety of … Last medically reviewed on February 23, 2016. How Is a Pulmonary Angiography Performed? The addition of spiral computed tomographic angiography 31 to the previously introduced lung scanning and conventional pulmonary angiography has opened a still ongoing debate among imaging specialists as to the relative role of this new application of computed tomography (CT) with respect to older techniques 32–36. The sensitivity and specificity of MR angiography to the level of lobar arteries were 100% and 85%, respectively, and to the level of segmental arteries, 94% and 78%, respectively. catheter will be gently guided through the vein to the right side of A Johns Hopkins Medicine will contact patients as we learn more about distribution plans from government officials.
