The club-record signing struggled to make an impact in west London, having scored only eight goals in 68 appearances, but the 28-year-old's career has been revived since returning to Holland in January.
"I am really happy here at PSV," Ruiz told Fox Sports Eredivisie. "They have a new project for next season to become champions with a strong squad. I would like to be part of that."
The forward - who will line up against England at this year's World Cup finals in Brazil - has scored four goals in 12 appearances for the Dutch outfit, but acknowledges that his parent club will have the final say on whether his move is made permanent.
"We have to see what happens," he said. "There are still games left, possibly play-offs, and after that the World Cup.
"What will happen depends on several things. I still have one year on my contract at Fulham."
Ruiz scored 24 league goals in Twente's title-winning campaign under former England manager Steve McClaren in 2010.
The Cottagers currently sit in 18th place in the Premier League, five points adrift of safety under new coach Felix Magath.
