    A study found that the radiation from CT scans—the tests regularly used to【C1】________ internal injuries or signs of cancer—is likely responsible for 2 percent of cancer cases in the United States.
    While lots of Americans undergo CT scans, that research is unlikely to come up in doctors’ offices: Two-thirds of【C2】________ in a new JAMA study reported hearing nothing of the risks of the diagnostic procedure. Meanwhile, 17 percent felt like they played an active role in a discussion over, whether this diagnostic test was the best path forward.
    "Our study indicates that most decisions to undergo outpatient CT are【C3】________ by physicians and risk communication is【C4】________," a team of researchers led by University of Colorado’s Tanner Caverly writes. "The risk communication that took place had limited【C5】________: respondents who recalled discussing the benefits and risks of imaging did not have better knowledge."
    Would a conversation about the【C6】________ risks have made a difference? Caverly’s team asked a few other questions that suggest it would: Patients undergoing the scan have little idea about the radiation【C7】________. One-quarter self-identified radiation as a risk of a CT scan; 37 percent were able to identify CT scans as having a higher level of radiation than a chest x-ray.
    There’s a growing movement in medicine right now to cut back on unnecessary treatment or【C8】________ of care. Much of this has been led by a group called Choosing Wisely, which has【C9】________ with dozens of medical societies to come up with lists of【C10】________ that doctors themselves don’t think they ought to be using.
    One of their key messages is that more care isn’t necessarily better; all medicine comes with some level of risk. That message does not, however, seem to be delivered in the doctor’s offices studied here.
【C7】
选项
答案J
解析 空格处需要形容词或分词作radiation的后置定语。上文一直在说CT扫描的辐射风险，本段还是讲这种风险，可知空格前的radiation仍然指CT扫描可能包含的辐射，involved“涉及的”符合语义。
