为了解延迟增强CT的诊断价值,对腹部增强CT检出的44例46个肾上腺肿块作了研究。其中男19例,女25例,年龄21～88岁。37例有肺癌等恶性病病史,另7例中,4例为肾上腺肿块的随访,3例因腹痛行CT检杏。经CT随访6月～2年,确诊了32例34个病变;经皮活检8例;手术4例。最后证实肾上腺腺瘤和转移瘤各23个。35例作了螺旋增强CT,层厚7mm,Pitch=1.5:1,在静脉团注对比剂后70s扫描,其余9例完成了常规增强CT,层厚7mm,间隔5mm,注射对比剂后40s扫描。44例均获得了15min的延迟增强扫描,所用扫描参数相同。44例在同时或4个月内还获得了肾上腺肿块的平扫CT,其中螺旋CT36例,常规CT8例。从平扫、动态扫描和15min的延迟增强扫
To understand the diagnostic value of delayed enhancement CT, 44 cases of 46 adrenal masses detected by abdominal enhanced CT were studied. 19 males and 25 females, aged 21 to 88 years old. 37 cases had a history of malignant diseases such as lung cancer, and the other 7 cases, 4 cases were followed up for adrenal mass, 3 cases of CT apricot due to abdominal pain. CT was followed up for 6 months to 2 years, 32 cases of 34 lesions were confirmed; 8 cases of percutaneous biopsy; 4 cases of surgery. Finally, 23 adrenal adenomas and metastases were confirmed. Thirty-five patients underwent helical CT, thickness 7mm, Pitch = 1.5: 1, scanned 70s after intravenous injection of contrast agent, and the remaining 9 patients underwent routine enhanced CT, thickness 7mm, interval 5mm, 40s after contrast injection . 44 cases were obtained 15min delay enhanced scan, the same scan parameters. Forty-four patients also received CT scan of adrenal mass at the same time or within 4 months, including 36 cases of spiral CT and 8 cases of conventional CT.
