The suspension of some research at a prominent Columbia University brain-imaging lab because of sloppy practices could have repercussions beyond that laboratory, potentially affecting brain-imaging studies nationwide and raising questions about the safety of participants, research experts said Saturday. The Kreitchman PET Center in Manhattan, part of Columbia University, halted brain-imaging studies after federal authorities reportedly found safety violations that could endanger patients and invalidate research findings. The center has admitted to poor manufacturing processes of radioactive compounds injected in patients and to sub-par record-keeping.
