Quickly roll to the left side of the room and IBJ through the crumble blocks before GT gets there, if it is alive. Starting from a jump or with a double bomb jump can help speed this up and make it much easier, but Samus needs to bomb slowly near the top to prevent hitting the crumble blocks before PLMs are overloaded. Get GT to jump away then again jump into IBJ and climb to the right item. With a speedy jump, it is possible to overload PLMs with one jump, then wait for it to get close and run under it and jump to the top right. Note that Samus can roll under GT, but when it attacks, it places stationary invisible projectiles, which may block Samus' path. Place a Power Bomb then quickly exit G-mode to quickly clear all of the bomb blocks, otherwise it is possible to get out with a few Bombs or Screw Attack.
