目的:应用彩色多普勒高频超声、CT、MRI检查眼部占位性病变,探讨眼球恶性肿瘤的各种影像学检查特征,为诊断和鉴别诊断提供依据。方法:应用彩色多普勒高频超声(探头频率7.5～10MHz)、CT、MRI对30例(33只眼)眼球恶性肿瘤进行检查,观察肿瘤的影像学特征。结果:眼球恶性肿瘤的影像学检查各有优缺点,彩色多普勒高频超声可以清楚显示瘤体内的钙化及血流分布情况,CT能够显示肿瘤向眼眶及颅内侵犯程度,MRI在显示肿瘤继发的眼内损害(如视网膜脱离、脉络膜脱离、出血等),以及向眼外浸润方面优于其他影像学检查。结论:三种影像学检查在诊断眼球肿瘤方面各有优缺点,应取长补短,优势互补,以提高肿瘤的定性诊断率。
OBJECTIVE: To investigate ocular mass lesions with color Doppler ultrasonography, CT and MRI, and to explore various imaging features of malignant tumors of the eye for the diagnosis and differential diagnosis. Methods: Thirty patients (33 eyes) with ocular malignancy were examined by color Doppler ultrasound (probe frequency 7.5 ~ 10MHz), CT and MRI, and the imaging features of the tumor were observed. Results: The malignant tumors of the eye have their own advantages and disadvantages of imaging examination, color Doppler ultrasonography can clearly show the tumor calcification and blood flow distribution, CT can show the tumor to the orbit and intracranial invasion, MRI in the display of tumor Secondary intraocular damage (such as retinal detachment, choroidal detachment, bleeding, etc.), as well as extravasation is superior to other imaging studies. Conclusion: The three imaging examinations have their own advantages and disadvantages in the diagnosis of eye tumors, should learn from each other’s strengths and complement each other to improve the qualitative diagnosis of tumors.
