[ 18 F]-PSMA-1007 PET imaging optimization and inter-rater reliability - a comparison of three different reconstructions read by four radiologists.

Objectives: To increase understanding of optimal imaging parameters [ 18 F]PSMA-1007 when imaging patients with prostate cancer and to determine interrater agreement using [ 18 F]PSMA-1007.

Methods: In this observational study, four independent physicians read reconstruction sets using bedtimes of 1, 2 and 3 minutes of patients undergoing [ 18 F]PSMA-1007. positron emission topography.

Comparison of Regularized Reconstruction and Ordered Subset Expectation Maximization Reconstruction in the Diagnostics of Prostate Cancer Using Digital Time-of-Flight Ga-PSMA-11 PET/CT Imaging.

Unlabelled: In prostate cancer, the early detection of distant spread has been shown to be of importance. Prostate-specific membrane antigen (PSMA)-binding radionuclides in positron emission tomography (PET) is a promising method for precise disease staging. PET diagnostics depend on image reconstruction techniques, and ordered subset expectation maximization (OSEM) is the established standard.

Renal resistive index is associated with acute kidney injury in COVID-19 patients treated in the intensive care unit.

Background: Renal resistive index (RRI) is a promising tool for the assessment of acute kidney injury (AKI) in critically ill patients in general, but its role and association to AKI among patients with Coronavirus disease 2019 (COVID-19) is not known.

Objective: The aim of this study was to describe the pattern of RRI in relation to AKI in patients with COVID-19 treated in the intensive care unit.

Methods: In this observational cohort study, RRI was measured in COVID-19 patients in six intensive care units at two sites of a Swedish University Hospital.

The future of breast cancer screening: what do participants in a breast cancer screening program think about automation using artificial intelligence?

Background: If screening participants do not trust computerized decision-making, screening participation may be affected by the introduction of such methods.

Purpose: To survey breast cancer screening participants' attitudes towards potential future uses of computerization.

Material And Methods: A survey was constructed.

Total spinal in an infant: can 'dry taps' occur with 20G Tuohy needles?

The loss-of-resistance technique was used to place a 20G epidural needle in the lumbar region in an anesthetized and paralyzed infant. There was no cerebrospinal fluid (CSF) leakage and a 24G catheter was inserted through the needle. At end of surgery, when the patient was breathing spontaneously and a bupivacaine bolus was given through the catheter, a total spinal block was identified.
