Hmm, honestly di ko sure kung may dedicated 3D/4D ultrasound clinic specifically in Marilao, pero usually yung mga private hospitals or OB clinics doon may ganitong services, try calling the bigger clinics near you or ask your OB kung saan sila nag-refer para sa fancy ultrasounds, kasi maraming moms dito nag-go sa Valenzuela or Meycauayan area na lang if may specialized ones doon. Better to call ahead kasi ang 3D/4D ay hindi lahat ng clinics ang equipment!
