The COVID-19 Reporting and Data System (CO-RADS) and the chest CT score were evaluated. HS measurements were performed based on CT images using a single region of interest placed on the right liver lobe (segments V-VII). HS was defined as a liver attenuation value <40 Hounsfield units. Data were collected and compared with the patients' prognostic parameters.Of the 152 inpatients, 137 patients (90.1%) had a CT score ≥3 and 109 patients (71.7%) had a CO-RADS score ≥4, 43 (28.2%) had HS. All patients with HS (100%) and 94/109 (86.2%) patients without HS had a CT score ≥3. There was a statistically significant difference between the two groups in terms of chest CT score (p=0.006). There was no statistically significant difference between the two groups in terms of CO-RADS score (p=0.291). The median CRP levels were significantly increased in patients with HS compared to patients without HS (p=0.023). There was no significant difference in ICU hospitalization and mortality due to the presence of HS (p>0.05).The current study revealed significantly higher chest CT scores in COVID-19 patients with HS measured on CT compared to those without HS. Opportunistic use of CT images for the detection of HS can be considered as an adjunctive tool in the risk analysis of COVID-19 patients hospitalized due to COVID-19 pneumonia.The severity of COVID-19 disease is increased in hospitalized patients with hepatosteatosis compared to patients with a normal liver. Density measurements for the evaluation of HS using opportunistic CT applications can be considered as an adjunctive tool in the prognostic evaluation of hospitalized patients with COVID-19 pneumonia. · Parlak AE, Erdem Toslak İ, Turkoglu Selcuk N.

This study aims to evaluate the diagnostic efficacy of various radiological parameters in PI-RADS 3 lesions to improve the decision-making process for prostate biopsies.This retrospective study included 76 patients with PI-RADS 3 lesions who underwent mpMRI and transrectal prostate biopsy at a tertiary university hospital between 2015 and 2022. Radiological parameters such as signal intensity, lesion size, border definition, morphological features, lesion location, and prostate volume were analyzed. Apparent diffusion coefficient (ADC) values and the patients' clinical data including age, prostate-specific antigen (PSA), and histopathological findings were also evaluated. Results: Among the 76 patients meeting the inclusion criteria, prostate cancer was detected in 17, with only one case being clinically significant (csPCa). Factors increasing malignancy risk in PI-RADS 3 lesions included poorly defined lesion borders, ADC values below 1180 μm²/sec, and prostate volume below 50.5 cc.

It is an established prognostic and predictive imaging marker of the cardiovascular risk profile. The prognostic relevance of the CAC score has been demonstrated for acute diseases, including the coronavirus disease 2019 (COVID-19) in preliminary studies. The aim of the present study was to prove the prognostic relevance of the CAC score in patients with coronavirus disease 2019.The present study used a nationwide radiological research platform to conduct a multicenter retrospective study. The study included a total of 541 patients, 176 of whom were female (32.5%). The mean age of the patients was 61.2 years ± 15.6 years. The coronavirus (SARS-COV-2) disease was confirmed in all patients by PCR testing. The CAC score was calculated using the Weston score, which is a semiquantitative method. The primary outcome of the study was 30-day mortality.The overall mortality rate within the 30-day period was 21.2%, with 115 patients dying. The mean Weston score was 3.0 ± 3.6. 128 patients (23.7%) exhibited no evidence of coronary calcifications, as indicated by a Weston Score of 0. In the univariable regression analysis, the presence of calcifications was found to be associated with mortality, with an odds ratio of 1.68 (95% confidence interval 1.08-2.59, p=0.01). However, this result did not remain statistically significant in the multivariable analysis (p=0.49). The Weston score was found to be associated with mortality in the univariable analysis, with an odds ratio (OR) of 1.10 (95% CI 1.04-1.14, p < 0.001), and in the multivariable analysis, with an OR of 1.06 (95% CI 1.005-1.138, p = 0.036).The imaging marker CAC score has been demonstrated to have a significant prognostic impact on 30-day mortality in patients diagnosed with coronavirus disease 2019 (COVID-19). It is incumbent upon the radiologist to acknowledge the sole presence of coronary calcifications as a relevant prognostic factor.

A B-mode scan, color-coded Doppler sonography, and CEUS were performed intraoperatively to analyze the focal lesions. The generated parametric images were based on continuous cine loops, acquired with a multifrequency T-probe (6-9 MHz), from the early arterial phase (0-15 seconds) to the portal venous phase (1 minute), generated by integrated perfusion software. Analyses of the CEUS loops were performed using TICs with respect to time-to-peak (TTP) and area under the curve (AUC). Perfusion analysis was performed in the center and periphery of the tumor as well as in healthy liver tissue. All tumor lesions were evaluated histopathologically to verify the diagnosis.Sufficient image quality was achieved in all cases using CEUS for TIC analysis. A comparison of all groups showed a clear difference compared with the center, margin, and healthy liver tissue in the measured parameters of TTP and AUC (p = 0.035 and p = 0.045, respectively). In detail, differences were observed in the CCC group (TTP: p = 0.025) and in the HepMET group (TTP: p = 0.009), particularly in the peripheral areas (strong arterial flooding with a rapid increase in the flooding curve), with equally clear tumor edge representation compared with healthy liver tissue, as shown by the AUC analysis (CCC AUC: p = 0.032 and HepMET AUC: p = 0.029). In patients with HCC, the perfusion pattern (starting from the center) showed the center to be more clearly distinguishable from the edge with significant TTP and AUC (p = 0.035 and p = 0.038).Intraoperative TIC analysis of malignant liver tumors is an important diagnostic tool for better highlighting liver tumor margins during surgery. · CEUS with dynamic vascularization.
