USS Assessment of Early Pregnancy

Our routine practice, when there is a suspicious of a non-viable pregnancy; we rely on the measurements of CRL and gestational sac to make the diagnosis. The current gridlines state that:
a) If the crown rump length (CRL) is > 7mm and there is no embryonic cardiac activity, this is defined as a missed fetal demise.
b) If the mean gestational sac diameter is > 25 mm and there is no yolk sac or embryonic pole, this is defined as an anembryonic pregnancy (blighted ovum)
c) If at the follow up scan after at least one week , there is still no embryonic cardiac activity or gestational sac remains empty, then diagnosis of non-viability can be made
