Prognostic Value of the Volumetric Parameters of Dual-Time-Point 18F-FDG PET/CT in Non-Small Cell Lung Cancer Treated With Definitive Radiation Therapy.
OBJECTIVE. The purpose of this study is to assess the effectiveness of the volumetric parameters of dual-time-point imaging (DTPI) with 18F-FDG PET (DTPI FDG PET) in predicting the prognosis of patients with non-small cell lung cancer (NSCLC) treated with definitive radiation therapy (RT). MATERIALS AND METHODS. ⋯ CONCLUSION. TLG and ΔTLG were significant prognostic factors in patients with NSCLC treated with definitive RT. In particular, a relatively low ΔTLG resulted in poor outcomes in terms of LCR and disease-specific survival.

Diagnostic Radiologists' Participation in the American Board of Radiology Maintenance of Certification Program.
OBJECTIVE. Physicians across specialties have expressed concerns about Maintenance of Certification (MOC) programs of American Board of Medical Specialties member boards, calling for research about MOC acceptance, adoption, and value. The purpose of this study was to characterize diagnostic radiologists' participation in the American Board of Radiology (ABR) MOC program, the framework for its new Online Longitudinal Assessment program. ⋯ CONCLUSION. Although diagnostic radiologists with time-limited certificates nearly universally participate in MOC, those with lifetime certificates (particularly general radiologists and those in smaller and nonacademic practices) participate infrequently. Low rates of nonmandated participation may reflect diplomate dissatisfaction or negative perceptions about MOC.
