Akak pun buat detail scan dekat Sentul, tapi honestly yang murah-murah memang limited ah! A few of my mum friends recommend cek clinic-clinic near Sentosa area or even go further to Rawang/Kepong, usually cheaper sikit from Sentul proper. Best you call around directly, Assunta or KPJ dekat situ pun boleh tanya, sometimes mereka ada package deals for scans yang lebih affordable!
