Saying, “I want it anyway,” the ICU physician insisted that his patient with breast cancer should get an MRI exam to look for lung metastases. My years of experience as a radiologist did not dissuade him; such a test would be a poor way to evaluate his patient’s lungs, even under ideal circumstances (which hers were not). She was on a ventilator, incoherent, and unable to hold her breath, rendering the study a useless waste of time and money. More important, her lungs, just days earlier, had been clear on a chest CT exam—the gold standard for detecting lung nodules. We already knew that she had no lung metastases.
