Tailored CT: primum non nocere.

摘要

Despite its vital diagnostic utility, the ionizing radiation used in CT is not benign. Patients have an increased risk of dying from a radiation-induced cancer for every pass through a CT scanner. One way to reduce this risk is to tailor CT, especially follow-up scans, to specific areas of concern. By doing so, we can help to minimize the small but real risk from this essential technology.
