The new, well-characterized 3 T methodology enables robust and accurate cardiac T(2)-mapping at 3 T with high spatial resolution, while the addition of a reference phantom improves reproducibility. This technique may be well suited for longitudinal studies in patients with suspected or established heart disease.
Pneumopathies radiquesPathophysiologie, classification, facteurs de risque et prise en charge en 2022 Malgré les améliorations des techniques d'irradiation à l'étage thoracique, la pneumopathie radique (PpR) reste une compli cation fréquente, en particulier dans le cadre du traitement du cancer pulmonaire. Cette complication, qu'elle soit précoce ou tardive, peut demeurer silencieuse ou causer une détresse respi ratoire potentiellement fatale. C'est pourquoi un faible degré de suspicion est nécessaire, de manière à débuter précocement un bilan d'investigation et décider de l'indication à un traitement spécifique. Dans cet article, nous discutons des hypothèses pathophysiologiques qui soustendent la PpR, des facteurs de risque de survenue, de la présentation clinique et radiologique, ainsi que de sa prise en charge.
Radiation-induced pneumonitis : pathophysiology, risk factors and work-up in 2022Despite technical improvements concerning lung irradiation modalities, radiation-induced pneumonitis remains a usual complication, notably in the field of lung cancer treatment. This complication may remain asymptomatic but can also lead to respiratory distress. Thus, a low degree of suspicion and a comprehensive work-up is mandatory to evaluate the indication for specific treatment. In this article, we discuss the hypothesized pathophysiologic pathways, risk factors, clinical/radiological presen tation and management.
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.
