“…2,[23][24][25] Although the capability of conventional non-contrast CT in providing multiplanar thin slices with good spatial resolution and three-dimensional images in orbital fractures 21,26,27 has nominated it as the imaging method of choice, a significant concern as to the hazard of radiation exists. [28][29][30][31][32][33] To obviate this concern, some investigators have suggested orbital ultrasonography as an alternative, with a sensitivity, specificity, positive-predictive value and negative-predictive value ranging from 85% to 95%, 57% to 100%, 57% to 100% and 60% to 91%, respectively. [10][11][12]15,16,18,19 In the present study, the corresponding values were 87.2%, 100%, 100% and 94.2%, respectively; suggesting a high diagnostic accuracy of ultrasonography in detecting orbital floor fractures.…”
