OBJECTIVE: In view of the implementation of magnetic resonance imaging (MRI) as an adjunct to ultrasonography (US) in prenatal diagnosis, this study sought to demonstrate normal penile growth on prenatal MRI. MATERIALS AND METHODS: This retrospective study included MRI scans of 194 male fetuses (18 to 34 gestational weeks [GW]) with normal anatomy or minor abnormalities. On sagittal T2-weighted MR sequences, penile length was measured from the glans tip to the scrotal edge (outer length), and also, from the glans tip to the symphyseal border (total length). Statistical description, as well as correlation and regression analysis, were used to evaluate penile length in relation to gestation. T-tests were calculated to compare mean outer/total length on MRI with published US data. RESULTS: Mean length values, including 95% confidence intervals and percentiles, were defined. Penile length as a function of gestational age was expressed by the regression equation: outer mean length= -5.514 + 0.622 *, and total mean length= -8.865 + 1.312 * (*= GW). The correlation coefficients were statistically significant (p < .001). The comparison between outer length on MRI and US data showed no significant differences, whereas total length on MRI and US data demonstrated significant differences (p< .001). CONCLUSION: Our MRI results provide a reference range of fetal penile length, which, in addition to US, may be helpful in the identification of genital anomalies. Outer penile length on MRI is equivalent to penile length measured on US, whereas total length is significantly different. Copyright © 2011 ISUOG. Published by John Wiley & Sons, Ltd. |
