68Ga-DOTATOC PET for the Evaluation of Gastroenteropancreatic Neuroendocrine Tumours
Gastroenteropancreatic neuroendocrine tumours (GEP-NETs) are a heterogeneous group of neoplasms that arise from the endocrine cells of the gastroenteropancreatic tract. The diagnostic work-up of these tumours include Computed Tomography (CT), Endoscopic Ultrasound (EUS), Magnetic Resonance Imaging (MRI). The majority of these tumours express somatostatin receptors on their surface. For this …
Core Temperature in Patients With OHCA
A prospective observational study aiming to monitor core temperature via an esophageal probe in out of hospital cardiac arrest during transport and until arrival in hospital.

Nitric Oxide Lung Diffusing Capacity in Systemic Sclerosis
To date, two devices to measure nitric oxide lung diffusing capacity (DLNO) are commercially available in Europe. Previous research has shown systematic between-device differences in lung diffusing capacity outcomes in healthy people (Radtke et al. ERJ Open Res. 2021 Sep 13;7(3)). The extent and magnitude of between-device differences in people …
