摘要
随着现代医学影像学技术的不断发展,其中的CT、MRI、超声检查和OCT等在眼科临床已经广泛应用,提高了眼科疾病诊断和治疗的水平.超声检查技术具有易于重复操作、无辐射的特点,对于眼内疾病和眼眶疾病的诊断应用价值较大,特别是眼内疾病优于CT、MRI; CT是眼眶疾病诊断的首选方法之一,它既能清晰显示眼眶的正常结构又能明确反映占位病变及眶壁骨质的改变,其显示骨质改变明显优于超声检查和MRI; MRI检查对于眼内脉络膜黑色素瘤的诊断具有特异性,眼眶病变是否发生视神经管和颅内蔓延,以及恶性肿瘤的眶外蔓延或术后复查判断是否复发,MRI检查明显优于CT;OCT做为一种非接触、无损伤性活体形态学检查方法,对于眼内结构及疾病的检查诊断是一种重要的手段.总之,影像学检查拓展了眼科检查手段,提高了临床诊断的准确性.
With development of the modern medical imaging technology,CT,MRI,ultrasound and OCT,etc,have been widely used in clinical ophthalmology and improve the level of diagnosis and treatment of eye diseases.Ultrasound has a large diagnostic application for intraocular disease.CT is the preferred method for the diagnosis of orbital disease,with the advantage of clearly showing the normal structure of the orbit,especially bone changes.MRI images has specificity for the diagnosis of ocular tumor,such as choroidal melanoma,it is also effective for searching the range of orbital and intracranial lesions by the optic canal spread,superior orbital fissure,and spread of malignant orbital tumor.OCT as a non-contact,non-invasive morphological examination in vivo is an important method for diagnosis of intraocular diseases.In summary,imaging examination improve the accuracy of diagnosis of clinical ophthalmology.
