Purpose The aim of our study is to compare the efficacy of positron emission tomography (PET) and magnetic resonance imaging (MRI) for detecting intraprostatic lesions in patients with clinically significant prostate cancer who underwent radical prostatectomy; additionally, investigate the benefits of rostate-specific membrane antigen (PSMA) PET-MR software fusion images to the diagnosis. Methods Thirty patients, who underwent radical prostatectomy between June 2015 and April 2018, were included in the study. Subjects with gallium PSMA PET-CT and multiparametric prostate MRI performed according to Prostate Imaging Reporting and Data System v2 criteria in our clinic were included in the study. 68Ga-PSMA PET-CT images were fused with MR sequences for analysis. Results The mean age of cases was 63.2 years (ranged from 45 to 79 years). Index lesions of 29 cases were detected by MRI and 22 of them by PET CT. Both modalities were found to be less sensitive for detection of bilaterality and multifocality (42.85% and 20% for MRI, 28.57% and 20% for PET CT, respectively). There was no statistically significant difference between modalities. It was observed that if a clinically significant tumor focus was not detected by MRI, it was small (6 mm or less) in diameter or had a low Gleason score. Conclusions Software fusion PSMA PET-MRI increased the sensitivity of the index lesion identification compared with PSMA PET-CT and also increased the sensitivity of real lesion size identification compared with multiparametric prostate MRI.

The neutrophil to lymphocyte ratio (NLR) predicts adverse clinical outcomes in several cardiovascular diseases. Our aim was to investigate the association of residual SYNTAX score (rSS) with the NLR in patients (n = 613) with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention. Patients were divided into 2 groups: group 1 with low NLR (<2.59) and group 2 with high NLR (>2.59). Coronary artery disease severity was calculated for both groups besides baseline clinical and demographic variables. Receiver operating characteristic curve analysis demonstrated that NLR with a cutoff value of 2.59 had good predictive value for increased rSS (area under the curve = 0.707, 95% CI: 0.661-0.752, P < .001). The median rSS value of group 2 was higher (2.0 [0-6.0]; 4.0 [0-10.0], P < .001) compared with group 1; the number of patients with high rSS was also higher in group 2 (26 [9.7%]; 107 [31.0%], P < .001). In multivariate logistic regression analysis, the NLR (odds ratio = 3.933; 95% CI: 2.419-6.393; P < .001) was an independent predictor of high rSS. Additionally, there was a positive correlation between NLR and rSS (r = 0.216, P < .001). In conclusion, higher NLR was an independent predictor of increased rSS in patients with STEMI.
