Lifetime attributable risk of cancer from CT among patients surviving severe traumatic brain injury.
The purpose of this study was to determine the lifetime attributable risk of cancer from CT among patients surviving severe traumatic brain injury. ⋯ Radiation exposure from the use of CT in the evaluation and management of severe traumatic brain injury causes negligible increases in lifetime attributable risk of cancer and cancer-related mortality. Treating physicians should not allow the concern for future risk of radiation-induced cancer to influence decisions regarding radiographic evaluation in the acute treatment of traumatic brain injury.

Importance of a personal history of breast cancer as a risk factor for the development of subsequent breast cancer: results from screening breast MRI.
The purposes of this study were to assess the importance of a personal history of breast cancer as a risk factor for patients referred for screening breast MRI and to evaluate the importance of this risk factor compared with family history. ⋯ A personal history of breast cancer is an important risk factor for the development of subsequent breast cancer. Given the results, consideration should be given to MRI screening of patients with a personal history of breast cancer.

Metallic implants are currently a contraindication for volunteer subjects and patients referred for 7-T examinations because of concerns related to magnetic field interactions and MRI-related heating. Artifacts may also be problematic. Therefore, the purpose of this investigation was to evaluate these MRI issues for 28 implants and other objects in association with a 7-T MR system. ⋯ These findings show that certain implants and objects may be acceptable for human subjects undergoing MRI examinations at 7 T, whereas others may involve possible risks. This information has important implications for individuals referred for MRI examinations at 7 T.

The Choosing Wisely initiative of the American Board of Internal Medicine Foundation: what will its impact be on radiology practice?
OBJECTIVE. The Choosing Wisely initiative is a large-scale effort to reduce the use of unnecessary tests and procedures, many of which involve imaging. CONCLUSION. By identifying specific tests and procedures that are often overused, unnecessary, inappropriate, or ineffective, Choosing Wisely places the onus on physicians to reduce their use.
