Hindi ko sure kung may 3D/4D ultrasound sa Tuguegarao mismo, kaya best bet mo talaga is to call the major hospitals and diagnostic centers dyan like Cagayan Valley Medical Center or ask your OB kung saan nila usually nire-refer ang patients for 3D scans. A few of us from Cagayan area actually go to Manila for the clearer scans, but hassle lang with the travel especially if you're heavily pregnant, try mo muna contact the hospitals locally kasi baka may partnership sila with imaging centers na available na ngayon!
