An morphology scan is performed in the second trimester, usually at around 18 to 20 weeks of pregnancy.

What should I do before morphology scan?

What should I do to prepare for my scan? Very little preparation is necessary. You should wear comfortable clothing which makes scanning your belly easy and your bladder should be comfortably full to help the sonographer get the best pictures. Please bring any previous scans with you to your appointment.
