Simultaneous computed tomographic angiography of the coronary and radial arteries

This study included 192 cases [age, mean ± standard deviation (SD),72.0 ± 9.9 years]. Mean TPA and TPR were 19.0 ± 2.3(SD) seco nds and 34.0 ± 10.0 s, respectively. Clear images of radial arteries were obtained in 89.6% (right) and 84.9% (left). Radiation exposure during cardiac CT angiography (CCTA) and radial artery CT angiography (RCTA) was 269.9 ± 155.6 mGy cm and 31.1 ± 12.3 mGy cm as dose length pro duct, respectively. RCTA immediately following CCTA was safely performed with minimal increase in radiation exposure and no additional contrast medium. These images can help in radial access as well as distal radial access in coronary interventions.
