为判断超声和CT诊断肝转移的准确性,作者回顾性分析了526例肿瘤患者的超声和CT检查。超声仪为西门子RA1,超声频率3.5兆赫,CT机为西门子Somatom SD,层厚8 mm。489例超声检查和223例CT检查均在术前7～14天内进行,160例同时作了两种方法的检查,对131例CT扫描阴性者加作了强化扫描。全部病例于超声和CT检查之后在Manz大学临床外科作剖腹手术或尸检,并根据手术结果作了原发肿瘤、肝转移的频率、数目、位置及大小的分析。结果表明,在149例既作了超声,又作了CT检查的病例组中,超声和CT对肝转移
To determine the accuracy of ultrasound and CT in the diagnosis of liver metastases, the authors retrospectively analyzed ultrasound and CT examinations in 526 patients with cancer. The ultrasound system was Siemens RA1 with an ultrasonic frequency of 3.5 MHz and the CT machine was a Siemens Somatom SD with a layer thickness of 8 mm. 489 cases of ultrasound examination and 223 cases of CT examination were performed within 7 to 14 days before operation. 160 cases were examined at the same time by two methods. Intensive scan was performed on 131 cases with negative CT scan. All cases underwent laparotomy or autopsy after clinical ultrasound and CT examinations at Manz University. The frequency, number, location, and size of primary tumors and liver metastases were analyzed based on the results of the surgery. The results showed that in 149 cases that had both ultrasound and CT scans, ultrasound and CT had a role in liver metastasis.
