Though more accurate compared to ultrasound for evaluating the axillary lymph node status FDG-PET/CT is only as sensitive as ultrasound when it comes to the detection of axillary lymph node metastases. Due to the low sensitivity FDG-PET/CT cannot act as a substitute for Sentinel lymph node biopsy. FDG-PET/CT is able to detect previously unknown locoregional extra-axillary lymph node metastases.
BackgroundClearly stated national recommendations for physical activity (PA) are available in many nations. Yet, their impact on national level policy-making might be considered modest at best. This paper analyses the approach selected to curtail this problem in Germany.Main textAcademics, government institutions and relevant stakeholders worked in collaboration to produce a series of national recommendations for PA and PA promotion published in 2016. Since their publication, these recommendations have achieved a measurable political impact through a systematic approach focused on dissemination and implementation strategies. For example, the German Conference of Health Ministers has acknowledged the national recommendations, endorsed their dissemination and proposed that they are included in measures within the Federal Prevention Act.ConclusionSince their publication, the national recommendations have yielded satisfactory political impact. The contributing aspects might partially be explained by the Multiple Streams Approach.
PET/MRI is superior to PET/CT in terms of tracing back a PET focus to a morphological correlate. For this reason PET/MRI enhances diagnostic certainty for lesions<10 mm and improves pretherapeutic lesion dosimetry in DTC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
