NT Scan vs. Detail/Anatomy Scan.

Hi, mummies. Nak tanya sikit la, since this is my first pregnancy and I'm not really familiar with NT Scan & Detail/Anatomy Scan ni. Boleh ke if kita skip NT Scan and proceed with Anatomy Scan terus nanti? Or is it better to do NT Scan first? Both actually sama ke boleh detect if ada possibility for abnormalities? Atau mcm mana? Saya try research tapi macam confused sikit dengan info-info dekat internet ni. Ada yang boleh explainkan dengan jelas and tepat tak?
