Because of overlying attenuating structures, sonographic imaging of the left adrenal gland is often difficult, especially in obese or pediatric patients. In a series of 50 consecutive patients, the left adrenal glands were examined in both the conventional right posterior oblique (RPO) position and using the new cava-suprarenal line (CSL) position. The CSL position permitted identification of the left adrenal gland in 90% of the patients; in contrast, the gland could be demonstrated in only 60% of the patients using the conventional RPO position. With the CSL position, the left adrenal gland could be imaged in half the time required with the conventional RPO position. The improved ability to demonstrate the left adrenal gland as well as the reduction in the required scanning time was particularly marked in obese and pediatric patients.
由于存在覆盖性的衰减结构，左侧肾上腺的超声成像常常很困难，尤其是在肥胖患者或儿科患者中。在连续的50例患者中，分别采用传统的右后斜位（RPO）和新的腔静脉-肾上腺上线（CSL）位对左侧肾上腺进行检查。CSL位使90%的患者能够识别左侧肾上腺；相比之下，采用传统RPO位时，只有60%的患者能够显示该腺体。采用CSL位时，对左侧肾上腺成像所需的时间仅为传统RPO位的一半。在肥胖患者和儿科患者中，显示左侧肾上腺的能力提高以及所需扫描时间的减少尤为明显。
