This study makes comparison between MRI and US
measurements of standard fetal biometrics (abdominal
circumference [AC], biparietal diameter [BPD], head
circumference [HC] and femur length [FL]), in the fetus
of 28-32 weeks gestational age. A real-time SSFSE
sequence was developed to allow the MR operator to
acquire images in the optimal plane for accurate
measurement. Results show that BPD and HC measurements
with MR were consistent. The length of time for
acquisition was acceptable. Further development of the
real-time SSFSE technique may be useful in comprehensive
biometric assessment, and in situations where accurate
measurements are important.
