Scanners fate following the assault on Genosha in New X-Men (1st series) #115-116 was unknown for years. New Avengers (1st series) #18 confirmed she was alive, but now depowered.
An Acolyte of similar appearance and skills named Surveyer and/or Screener appeared in Avengers (1st series) #357. This character was most likely an early version of Scanner, but if not, Scanner's first appearance was Uncanny X-Men (1st series) #300. Her real name was only revealed in the Marvel Handbooks.
