Noninvasive Ventilation in Cystic Fibrosis: Clinical Indications and Outcomes in a Large UK Adult Cystic Fibrosis Center.

Background: Noninvasive ventilation (NIV) is routinely used to treat patients with cystic fibrosis and respiratory failure. However, evidence on its use is limited, with no data on its role in disease progression and outcomes. The aim of this study was to assess the indications of NIV use and to describe the outcomes associated with NIV in adults with cystic fibrosis in a large adult tertiary center.

Cardiac computed tomography and conventional angiography in the diagnosis of congenital cardiac disease in children: recent trends and radiation doses.

Background: The use of imaging that employs ionising radiation is increasing in the setting of paediatric cardiology. Children's high radiosensitivity and the lack of contemporary radiation data warrant a review of the radiation doses from the latest "state-of-the-art" angiography and computed tomography systems.

Objectives: In children aged less than 16 years with congenital cardiac disease, we aimed to report: recent trends in the use of diagnostic angiography and cardiac dual-source computed tomography; the characteristics, lesions, and imaging histories of patients undergoing these procedures; and the average radiation doses imparted by each modality.

Complete left pericardial defect: evaluation with supine and decubitus dual source CT.

We present a case of complete left pericardial defect which was evaluated with retrospectively gated dual source CT. Imaging findings included right heart chamber dilatation, extreme levoposition and excessive cardiac mobility which was demonstrated by repeat imaging in the left lateral decubitus position. Cardiac CT is an excellent means of evaluating pericardial disease owing to its high spatial resolution.
