| Abstract;Introduction: Magnetic resonance imaging(MRI) gives a much more detailed picture of the soft tissue than computerized tomography(CT). In blowout fracture cases, it is very easy to observe the incarcerated orbital tissue. Subjects: We performed MRI in 19 blowout fracture cases. Results: After evaluating the images, we found three advantages of MRI. The first is that even small herniation of the orbital contents can easily be detected because the orbital fatty tissue contrasts well around the other tissues in MRI. The second is that the incarcerated tissues can be clearly differentiated because a clear contrast between the orbital fatty tissue and the extraocular muscle can be seen in MRI. The third is that the running images of the incarcerated muscle belly can be observed because any necessary directional slies can be taken in MRI. Conclusion: These advantages are very important in the diagnosis of blowout fractures. MRI should be employed in blowout fracture cases in addition to CT. (author abst.) |
