Rationale And Objectives: To assess the performance of Large Language Models (LLMs) in detecting and correcting MRI artifacts compared to radiologists using text-based and visual questions.
Materials And Methods: This cross-sectional observational study included three phases. Phase 1 involved six LLMs (ChatGPT o1-preview, ChatGPT-4o, ChatGPT-4V, Google Gemini 1.
Background: To investigate the relationship between pericarotid fat density measured in carotid CTA and vulnerable carotid plaque.
Methods: This retrospective study included 374 participants who underwent carotid CTA between June 1, 2021, and December 1, 2021 (234 males, median age 68 years [interquartile range: 61-75]). Two groups, symptomatic and asymptomatic, were defined based on either diffusion-weighted MRI or a clinical history of acute ischemia or TIA within 6 months before or after CTA.
Tigecycline is a parenteral glycycline antibiotic that is used to treat severe infections caused by susceptible organisms, butitis also associated with hepatotoxicity. We present 2 similar patients with hepatic steatosis possibly associated with early tigecycline after transplant. In the first case, a 61-year-old woman underwent liver transplant for acute severe hepatitis; 6 days posttransplant, because of nonroutine resistant fever, the patient received tigecycline combined with daptomycin.

Objectives: Sarcopenia is an important metabolic disorder associated with end-stage liver disease and is an independent predictor of mortality in liver transplant candidates. We evaluated effects of pretransplant muscle mass, muscle quality, and visceral adipose tissue on mortality after liver transplant.
Materials And Methods: For 2015-2020, we included 65 liver transplant recipients whose records contained pretransplant liver computed tomography images.

Objective: This study aimed to investigate the effect of mutations by comparing wild-type SARS-CoV-2 and Omicron regarding clinical features in patients with COVID-19. It also aimed to assess whether SARS-CoV-2 cycle threshold value could predict COVID-19 severity.
Methods: A total of 960 wild-type and 411 Omicron variant patients with positive results in SARS-CoV-2 real-time reverse transcriptase polymerase chain reaction test from oropharyngeal and/or nasopharyngeal samples during their hospital admissions were included in this retrospective study.
Pacemaker-associated superior vena cava (SVC) syndrome is increasingly recognized as a nonmalignant type of SVC syndrome. Computed tomographic (CT) angiography is the first choice of imaging for diagnosis but in some cases there is discrepancy between the clinical findings and CT images. In this report we present the role of contrast study with transesophageal echocardiography in a patient with suspicion of SVC syndrome but inconclusive CT findings.

For surveillance colored Doppler ultrasound (CDUS) is a standard method of noninvasive evaluation having the advantages of availability, cost-effectiveness, and lack of nephrotoxicity and radiation. We evaluated CDUS for primary surveillance tool after elective EVAR by comparing with computerized tomography.

The widespread use of central venous catheters, ports, pacemakers, and defibrillators has increased the incidence of benign SVCS. We present a post-pacemaker-implantation case of SVCS manifesting as positional syncope.

Methods: Eighteen patients with clinically and/or pathologically proven Wilson's disease underwent triphasic MDCT. Arterial, portal, and equilibrium phase images were obtained.
Purpose: To compare doxorubicin-loaded HepaSphere transarterial chemoembolization versus conventional transarterial chemoembolization in terms of survival, time to recurrence, acute reversible hepatotoxicity, postembolization syndrome, and chemoembolization-related mortality and morbidity.
Materials And Methods: One hundred twenty-six patients (103 men, 23 women; mean age, 64.3 y) with unresectable hepatocellular carcinoma (HCC) who underwent conventional chemoembolization between January 2007 and March 2011 or drug-eluting embolic (DEE) chemoembolization (after the protocol change) between March 2011 and October 2014 were included in a retrospective analysis.

Recent guidelines and consensus reports recommend endoscopic injection therapy with N-butyl-2-cyanoacrylate as the first-line treatment for bleeding-isolated gastric varices and gastroesophageal varices types 1 and 2. Embolization is a rare but serious complication of cyanoacrylate injection, which may be fatal in some cases. Herein, we present a patient who developed splenic infarction after N-butyl-cyanoacrylate injection for gastroesophageal varices type 2 and discuss the potential reasons and tips to prevent the occurence of embolization.

Materials And Methods: PBBD was performed after traversing hepaticojejunostomy strictures in 89 patients (40 male, 49 female; age range, 19-84 y; mean age ± SD, 54.5 y ± 14.
Patients with ankylosing spondylitis (AS) have an approximately two-fold increased death rate compared to the general population, which is predominately caused by increased cardiovascular risk. The prevalence rate for myocardial infarction is approximately 2-3 fold increased as compared with the general population. The inflammatory process appears to have an important role in causing this excess cardiovascular risk.

Materials And Methods: Contrast radiography and endoscopy revealed EJ fistulas in 14 patients. SECMSs were implanted both fluoroscopically and endoscopically to seal fistulas.
Situs inversus totalis is a rare condition that may not cause symptoms and often occurs concomitantly with other congenital anomalies. Special attention must be given to these patients when invasive interventions are required. There are only a few reports concerning percutaneous transhepatic biliary interventions in situs inversus totalis, but technical details were not fully explained.
