摘要
目的:总结甲状腺腺瘤CT三期增强扫描的表现,提高CT的诊断价值。方法:回顾性分析14例经手术、病理证实的14例甲状腺腺瘤的CT资料,观察病灶的大小、数目、边缘、密度及三期增强的强化特点。结果:14例甲状腺腺瘤表现为单发(8例)或多发(6例)的结节共21个,边缘清晰(17个)或不清(4个),密度均匀(9个)或不均(12个),伴囊变(10个)、坏死(4个)、钙化(4个)、出血(1个),病灶呈低密度(20个)或高密度(1个),增强扫描呈均匀强化(9个)、不均匀强化(8个)、边缘环状强化(4个),14个实质分为主的病灶中,强化峰值可出现在动脉期(7个)、静脉期(5个)、延时期(2个)。结论:多排螺旋CT三期增强扫描结合平扫对甲状腺腺瘤诊断具有重要的诊断价值。
Objective To summarize the performance of thyroid adenoma in three phase enhanced CT scanning,and to improve the di- agnostic value of CT. Method CT data of 14 cases of thyroid adenoma who were proved by operation and pathology were retrospectively ana- lyzed ,and observed the lesion size ,number,density ,edge enhancement and characteristics of three stage enhance. Results Of the 14 cases of thyroid adenoma,single(8 cases ) or multiple nodules (6 cases ) of the total 21 ,clear edge ( 17 ) or not ( 4 ),uniform density ( 9 ) or not ( 12 ) ,cystic degeneration ( 10 ) ,necrosis ( 4 ) ,calcification ( 4 ) ,bleeding ( 1 ) ,the lesions showed low density ( 20 ) or high density ( 1 ) ,enhanced scan showed homogeneous enhancement ( 9 ) ,inhomogeneous enhancement ( 8 ),edge enhanced ring (4) ,14 lesions with the essence as the main ingredients,enhanced peak can be seen in the arterial phase ( 7 ) ,venous phase ( 5 ) ,the delay peri- od ( 2 ). Conclusion Multi - slice spiral CT three enhanced scanning combined plain has important diagnostic value for thyroid adenoma diagnosis.
