Ang dami na ng ob-gynos with ultrasound machines sa Taguig ngayon, lalo na sa BGC at Fort areas! Maraming hospitals din like Makati Medical, Asian Hospital, at St. Luke's have good sonologists, pero if you're looking specifically within Taguig mismo, I'd suggest asking your OB first kung saan sila nag-refer, or you can call the major clinics directly, a few of us prefer to go sa hospitals kasi they have updated equipment at mas organized ang records.
