There were differences in the CSA of the ulnar nerve between some age groups, but there was no variation with sex or handedness. Sonography can evaluate the morphologic changes of the nerve during flexion of the elbow.

ORIGINAL ARTICLE PURPOSE We aimed to test the null hypothesis that relative apparent diffusion coefficient (rADC) and relative signal intensity values (rSI HASTE ) do not change in the evaluation of placental maturation with advancing gestational age. MATERIALS AND METHODSFifty-six fetuses with diffusion-weighted magnetic resonance imaging (DW-MRI) data were enrolled in this retrospective study. Fetuses were analyzed in three different gestational age groups: group 1, 18-23 weeks; group 2, 24-28 weeks; and group 3, 29-38 weeks. The rADC (mean ADC/ADC globe ) and rSI HASTE values (mean SI HASTE /SI globe ) were obtained. Two radiologists experienced in fetal MRI who were blinded to the patient information reviewed MRI images independently. Kruskal-Wallis Test was used to compare the rADC and rSI HASTE with gestational age groups. The agreement between the two blinded readers was tested using Krippendorff's alpha ratio. RESULTSBoth placental rADC values and placental rSI HASTE values were not significantly different between the gestational age groups (P = 0.688 and P = 0.280, respectively). rADC and rSI HASTE measurements were reproducible with a good agreement between the two readers (Krippendorff's alpha ratio was 0.613 and 0.778, respectively). CONCLUSIONThe rADC and rSI HASTE values do not change with advancing gestational age.
