To compare the value of US and CT for the detection and analysis of splenic abnormalities, we reviewed the medical records and imaging findings of 93 patients with 93 proven textural lesions of the spleen, which were visualized by US and/or CT. US revealed the abnormality in 91 (97.8%) patients and CT in 74 (79.6%) patients. US was more sensitive than CT in the detection of malignant lesions, particularly splenic lymphoma, while US and CT were equally effective in benign lesions. In 2 patients, one with sarcoidosis and the other with an acute infarct, the lesion was visualized by CT but not by US. On CT, i.v. injection of contrast material improved both the sensitivity of the examination and the delineation of the abnormality. The echogenicity or the attenuation of the lesions did not usually allow differentiation between the various benign and malignant splenic lesions. US is recommended as the method of choice for splenic imaging.
为比较超声（US）和计算机断层扫描（CT）在脾脏异常检测及分析中的价值，我们回顾了93例经证实存在93处脾脏结构性病变患者的病历及影像检查结果，这些病变均通过超声和/或CT得以显示。超声检查发现91例（97.8%）患者存在异常，CT检查发现74例（79.6%）患者存在异常。在检测恶性病变尤其是脾淋巴瘤方面，超声比CT更敏感，而在良性病变检测中，超声和CT效果相当。有2例患者，1例患有结节病，另1例患有急性梗死，其病变在CT上可见，但超声未显示。在CT检查中，静脉注射造影剂可提高检查的敏感性及病变的清晰度。病变的回声或衰减情况通常无法区分各种良性和恶性脾脏病变。超声检查被推荐为脾脏成像的首选方法。
