"Knowing the specific name of a device is not important; in fact, it is sometimes impossible, because a slight modification of a device design usually leads to a new name. It is important, however, to recognize the presence or absence of a device (if the patient’s clinical history suggests one is present), to understand its function, and to identify the complications associated with its use. The referring physician knows what device he or she has installed, but he or she relies on the radiologist to determine the postoperative location of the device and its integrity."
BI-RADS should use "foreign body" instead of "implantable object."
