Abstract
Objective
To compare contrast-enhanced ultrasound and contrast-enhanced magnetic resonance imaging
for the assessment of vascularization of hydroxyapatite orbital implants.
Methods
Ten patients who underwent monthly contrast-enhanced ultrasound and contrast-enhanced
magnetic resonance imaging following implantation were analyzed. The two modalities
were compared according to their ability to visualize the progress of vascularization
at monthly intervals.
Results
There were no differences in the findings shown by these two methods. Contrast-enhanced
ultrasound provided better visualization of the dynamic process of vascularization
than contrast-enhanced magnetic resonance imaging. There were no significant differences
in the areas and the time to completion of fibrovascular ingrowth observed by contrast-enhanced
ultrasound and contrast-enhanced magnetic resonance imaging, indicating that the findings
of these two examinations were consistently similar.
Conclusions
Contrast-enhanced ultrasound is useful for the assessment of vascularization of hydroxyapatite
orbital implants and provides better visualization of the dynamic process than contrast-enhanced
MRI.
