Risk factors of bladder stones in neurogenic lower urinary tract dysfunction: A real-world study.

Objective: The objective of this study is to investigate the incidence and risk factors for stone formation and recurrence in patients with neurogenic lower urinary tract dysfunction (NLUTD) in a real-world cohort.

Materials And Methods: A retrospective cohort study was conducted on all patients with NLUTD who underwent bladder stone treatment between 2010 and 2022. Univariate and multivariate Cox models were used to identify the potential risk factors for stone recurrence.

Ga-PSMA-11 PET imaging in patients with ongoing androgen deprivation therapy for advanced prostate cancer.

Purpose: Prostate-specific membrane antigen (PSMA) targeted positron emission tomography (PET) imaging significantly improved the detection of recurrent prostate cancer (PCa). However, the value of PSMA PET imaging in patients with advanced hormone-sensitive or hormone-resistant PCa is still largely unknown. The aim of this study was to analyze the detection rate and distribution of lesions using PSMA PET imaging in patients with advanced PCa and ongoing androgen deprivation therapy (ADT).

A pilot study on lung cancer detection based on regional metabolic activity distribution in digital low-dose 18F-FDG PET.

Objectives: To investigate the potential of automatic lung cancer detection on submillisievert dose F-fludeoxyglucose (F-FDG) scans using different positron emission tomography (PET) parameters, as a primary step towards a potential new indication for F-FDG PET in lung cancer screening.

Methods: We performed a retrospective cohort analysis with 83 patients referred for F-FDG PET/CT, including of 34 patients with histology-proven lung cancer and 49 patients without lung disease. Aside clinical standard PET images (PET) two additional low-dose PET reconstructions were generated, using only 15 s and 5 s of the 150 s list mode raw data of the full-dose PET, corresponding to 10% and 3.
