title: [The value of color Doppler imaging ultrasound in diagnosis of orbital diseases].
abstract: OBJECTIVE
  To study the useful value of color Doppler imaging (CDI) ultrasound in the diagnosis and differential diagnosis of orbital diseases.
  
  
  METHODS
  By using the technique of CDI ultrasound, 288 cases with orbital diseases were examined to show color Doppler flow imaging and pulsed wave Doppler (PWD) spectrum.
  
  
  RESULTS
  Among 288 cases of the orbital diseases, 38 cases of malignant tumors and 23 cases inflammatory pseudotumors showed the signals of blood flow. From CDI ultrasound examination, there were 18 in 23 cases with benign mixed tumors of the lacrimal gland showing artery blood flow and 22 in 28 cases with neurilemoma showing signals of blood flow. No blood flow was obtained in 62 among 74 cases with cavernous hemangioma, in 16 cases of dermoid cysts or epidermoid cysts and 1 case of lipoma. From CDI, rich blood flow was seen in 4 and scarce in 3 cases with meningioma, and in 6 cases of optic nerve gliomas, there were 5 cases without any blood flow signals. Other 2 cases with benign hemangioendothelioma, 2 hemangiopericytoma and 1 neurofibroma showed rich or scarce blood flow signals. Among 29 cases of venous hemangiomas, 16 cases showed venous flow. Three cases with arteriovenous aneurysms showed artery blood flow in the CDI. Fifteen cases with varicosis exhibited a dynamic blood flow changes in the CDI. Six cases with infantile hemangioma, the decreased blood supply was shown in the CDI after treatment. In the thirteen cases with carotid artery cavernous sinus fistula, including 8 cases of internal carotid artery cavernous sinus fistula (CCF) and 5 dural cavernous sinus fistula (DCF), dilated superior ophthalmic vein (SOV) with arterialized blood flow was seen. In the mean time, PWD showed that the SOV of CCF had a higher velocity and a higher flow volume than that of DCF, while its resistance index was lower than that of the DCF. In 1 case with thrombophlebitis, its SOV showed dilated superior ophthalmic vein without blood flow.
  
  
  CONCLUSIONS
  CDI can provide the information of color blood flow in orbital diseases, especially the tumors with rich vascular tissue and orbital vascular diseases. It is important in the diagnosis and differential diagnosis of the orbital diseases in combination with B-mode ultrasound, CT or MRI.
