Scanning and Tracing very detailed black and white pen art. (All hard lines and contrasting no shading.)

I am scanning my very detailed Black and white pen drawings and once i do, i am trying to trace them to have vector images i can manipulate but every type of scan ruins the drawings. Is there a better way i can go about scanning my drawings and preparing them for manipulation and clean up.

Also how can i have the "black" in the images to be recognized as borders to manipulate.

Thank you for your time.
