The specificity and sensitivity of the assay were 97.5% (95% CI 87.1-99.9) and 98.6% (95% CI 92.7-99.9), respectively, and 6.5% of the results were inconclusive. The application of this test in early pregnancy would avoid unnecessary antenatal...

The good correlation described between CC and abdominal circumference and FL suggests that cardiac measurements in early pregnancy alone, or related to other fetal biometric parameters, could be used as a screening tool to identify fetuses at risk...

Conclusion: In our experience, the measurement of transverse cerebellar diameter cannot be considered as a useful tool in the detection of aneuploidy in early pregnancy. The data concerning trisomy 13 are too small, so...
