PURPOSE
To determine the ability to visualize the origin of the right inferior phrenic artery (RIPA) and the left inferior phrenic artery (LIPA) by multidetector row computed tomography (MDCT) in a population without disease of the liver.
METHODS
The origin of the RIPAs and the LIPAs were evaluated using arterial-phase MDCT images in 200 patients.
RESULTS
The RIPA origin was detected in all cases, while LIPA origin was detected in 193 (96.5%) cases. RIPA and LIPA originate as a common trunk from the aorta (16%) and celiac trunk (20%). RIPAs originated separately from the aorta (29%), celiac artery (19.5%), right renal artery (10.5%), left gastric artery (3%), and proper hepatic artery (0.5%). LIPAs originated separately from the celiac artery (38.5%), aorta (16%), left renal artery (0.5%), left gastric artery (2.5%).
CONCLUSIONS
Arterial-phase images of MDCT could demonstrate the origin of the non-dilated IPAs in a population without the disease of the liver.
目的
确定在无肝脏疾病人群中，通过多排螺旋计算机断层扫描（MDCT）可视化右膈下动脉（RIPA）和左膈下动脉（LIPA）起源的能力。
方法
使用动脉期MDCT图像评估200例患者的RIPA和LIPA起源。
结果
所有病例均检测到RIPA起源，而193例（96.5%）检测到LIPA起源。RIPA和LIPA共同起源于主动脉（16%）和腹腔干（20%）。RIPA分别起源于主动脉（29%）、腹腔动脉（19.5%）、右肾动脉（10.5%）、左胃动脉（3%）和肝固有动脉（0.5%）。LIPA分别起源于腹腔动脉（38.5%）、主动脉（16%）、左肾动脉（0.5%）、左胃动脉（2.5%）。
结论
MDCT动脉期图像可显示无肝脏疾病人群中未扩张的膈下动脉的起源。
