OBJECTIVE
The purpose of this study was to characterize pathologically proven adrenocortical carcinoma by examination of washout attenuation characteristics on contrast-enhanced CT images.
CONCLUSION
Adrenocortical carcinoma has relative contrast retention on delayed contrast-enhanced CT. All tumors in this series had a relative percentage washout less than 40%, a finding consistent with malignant disease.
目的
本研究的目的是通过检查对比增强CT图像上的洗脱衰减特征来对经病理证实的肾上腺皮质癌进行特征描述。
结论
肾上腺皮质癌在延迟对比增强CT上有相对的对比剂滞留。本系列中的所有肿瘤的相对洗脱百分比均小于40%，这一发现与恶性疾病一致。
