[Photographic diagnosis for common intraorbital tumors].

OBJECTIVE

To compare and analyze the modern photographic methods used for localization and analysis of the nature of intraorbital tumors.

METHODS

B-scan, CT scan and magnetic resonance imaging (MRI) were used to examine six types of common intraorbital tumor (20 cases for each type).

RESULTS

Each method can locate and show the nature of the lesions, and B-scan has a better value to display internal structure and dynamics of orbital lesions. CT can discover the lesions and exactly show their locations, while MRI is more valuable to display the optic nerve tumor and the extension of intraorbital tumor to extraorbital regions.

CONCLUSIONS

All the above methods can locate and show the nature of intraorbital tumors, and each has its own special defects and advantages which can be complementary to one another.
