Objective Patients with prostate cancer are monitored by prostate-specific antigen (PSA) evaluation and PET [PET/computed tomography (CT)]. The aim of our study was to evaluate correlations between PSA levels and standardized uptake values (SUV) in patients with recurrent prostate cancer. Methods We analyzed 282 prostate cancer patients undergoing PET-CT due... Leggi di più

Objectives The use of 68Ga–prostate-specific membrane antigen positron emission tomography/computed tomography is spreading due to its clinical benefits. In this study, we aim to determine the intra- and interobserver agreement levels of 68Ga– prostate-specific membrane antigen-I&T positron emission tomography/computed tomography according to molecular imaging tumor-lymph node-metastases reporting system.

Objectives Cognitive impairment is a common non-motor feature of Parkinson’s disease (PD). However, the underlying pathophysiology of cognitive decline is unclear. We investigated the association of striatal dopamine transporter (DAT) loss with cognitive function and cerebral cortical metabolism in PD. Methods Twenty-eight patients (63.1 ± 7.1 yrs, M:F = 15:13)... Leggi di più

Objective Several different methods for measuring glomerular filtration rates (GFRs) have been developed in search of a more accurate and simplified technique. Currently, the main methods used are the slope-intercept and distribution volume techniques. In this work, 2922 GFR studies have been retrospectively reanalysed as two- and single-blood sample methods... Leggi di più
