Purpose This study is to evaluate an effect on quality of angiographic image, when the contrast volume is reduced in head angiography by MDCT Materials and methods Total forty patients have been examined a head angiography by MDCT. Twenty patients (A group) of forty patients have been examined with contrast madia with 100ml, the other twenty patients (B group) have been examined with contrast madia with 60ml and normal saline with 40 ml. Speed of injection by auto injector was 4-5cc per Second. Dual source CT(Definition, Siemens, Erlangen, Germany) and dual auto injector (Optivantage, TYCO) were used for this study. The obtained images were reconstructed three dimension, and then that was visually evaluated by three radiological technologists. A value of CT number (Hounsfield Unit) was measured on three portion including internal carotid artery (ICA), M1 of middle cerebral aitery (MCA), Basal Artery (BA). Results In the visual evaluation, the average score of A group was 2.43±0.45, and B group was 2.40±0.44. In the value of CT number, ICA, M1 of MCA, and BA A group were 441.99±65.26, 242.84±41.72, and 331.42±58.07, respectively. B group were 413.78±51.03, 229.16±32.33, and 305.13±67.26, respectively. Conclusion When testing used quantity of the contrast media that is reduced 40%, we could know that It don’t effect the image quality, and we basically think of dangerous element about increasing a side effect of the contrast media with developing CT test. If we can reduce the amount of the using without decreasing the image quality, the study will develop more safe ai1d reliably.
