my wife had her 24 weeks' scan yesterday (Fetal Anomaly Scan). The scan found everything allright but I am still a little worrying about because of one of the aspect of the scan. This is the TCD (transcerebellar diameter) value that is 28.6 mm at 24 + 0 weeks. It looks a little bit higher than the average but still within the limit. Could you please explain me if I should worry about anything and what does it mean if this value is higher than the average?
