Our facility is using nitroglycerin spray in for the purpose of widening the coronary artery in coronary CTA. There is work to dilate the blood vessels throughout the body as well as expand the coronary arteries to nitroglycerin. We have investigated whether also useful in abdominal CTA to use this effect. It was studied in 15 patients taken at 120kV and 80kV. ① without nitroglycerin (80kV/120kV) ② with nitroglycerin (80kV/120kV) Compared patient is 70.4 years average age. Each image was visually evaluated according to the fifth rated of image quality and vascular depiction performance displays in VR. Quality and vascular depiction performance is improved easily by using nitroglycerin. This effect is greater than the effects obtained at a low tube voltage. There was no significant difference 120KV and 80kV using nitroglycerin. It is possible to be used for different parts and integrated tube voltage.
Nitroglycerin Spray is possible to enhance the depiction performance while still ensuring the quality of the CTA.
