Hi! Sorry, walang specific CAS ultrasound experience ko sa Makati or BGC area, pero a few of my mum friends do their prenatal scans sa hospitals like Makati Medical Center at The Medical City kaya pwede mong tanungin sila directly para sa CAS availability and pricing, usually mas mahal ang specialized scans kaya good idea mag-compare. You could also call your OB's clinic since sila usually may partnerships na with imaging centers and they know kung saan best ang quality!
