Ultrasound in orbital diagnosis

Abstract:
Ultrasound is a safe and useful method of detecting, localizing, and differentially diagnosing orbital lesions. Diagnosis using B-scan and C-scan techniques depends on the qualitative recognition of patterns based on the location and shape of a lesion together with the distribution in number and amplitude of echoes arising from within a lesion. In addition, the sound-attenuating properties of a lesion, determined by changes in the appearance of deeper structures, may aid in identification.
