Identification of specific SUVmax ratios enhances diagnostic accuracy for staging of intrathoracic nodes in lung cancer.

Introduction: Studies demonstrating limited accuracy of 'positive' and 'negative' lymph nodes on fluorodeoxyglucose (FDG) PET-CT in staging for lung cancer have led to guidelines stating mediastinal nodes enlarged on computed tomography, irrespective of FDG uptake, require endobronchial ultrasound (EBUS)-transbronchial needle aspiration (TBNA). However FDG uptake occurs on a continuous spectrum and the use of standardised uptake value (SUV)max ratios, rather than a binary classification, may have improved diagnostic accuracy.

Methods: This was a retrospective analysis of patients with lung cancer who had PET-CT and EBUS-TBNA in 2015-2018.

Does intravenous glucagon improve common bile duct visualisation during magnetic resonance cholangiopancreatography? Results in 42 patients.

Introduction: Magnetic resonance cholangiopancreatography (MRCP) has been demonstrated as a reliable, non-invasive means of biliary tract imaging among patients with suspected choledocholithiasis. The aim of this study was to establish the impact of intravenous glucagon administration (IVGA) upon visualisation of the common bile duct (CBD) and ampulla of Vater during MRCP.

Materials And Methods: Forty-two consecutive, non-diabetic subjects with a working diagnosis of symptomatic choledocholithiasis were scanned, pre- and post-IVGA using the half-Fourier, single shot, turbo-spin-echo (HASTE) sequence.
