Role of positron emission tomography-computed tomography in endometrial cancer

open access: yesJournal of Turkish Society of Obstetric and Gynecology, 2017
The efficacy of preoperative 18F-fluoro-D-glucose (18F-FDG) positron emission tomography-computed tomography (PET-CT) in endometrium cancer is controversial. We examined the efficacy of PET-CT and the association between maximum standardized uptake value (SUVmax) and prognostic factors in endometrial cancer.Thirty patients with endometrial cancer ...

Mitochondrial CISD1 Modulates Microglial Metabolic Reprogramming to Drive Stress Susceptibility in Mice

open access: yesAdvanced Science, EarlyView.
CDGSH iron sulfur domain 1 (CISD1) mitigates oxidative stress by promoting NADH oxidation and Coenzyme Q (CoQ) reduction. Under chronic stress, elevated CISD1 expression in microglia enhances NAD⁺ production, thereby increasing GAPDH activity and glycolytic flux, while reducing ATP synthesis by inhibiting proton transfer from mitochondrial complexes I ...

Diagnosis of giant cell arteritis by head-contrast three-dimensional computed tomography angiography: two case reports

open access: yesJournal of Medical Case Reports, 2019
Introduction Temporal artery biopsy is essential for the diagnosis of giant cell arteritis. It has been shown that 18F-fluorodeoxyglucose positron emission tomography-computed tomography, magnetic resonance angiography, and ultrasonography are useful for

Unveiling Dipolar Interaction‐Driven Magnetic Field Inhomogeneities in T2 MRI Contrast Agents

open access: yesAdvanced Science, EarlyView.
In this study, chemically designed nanoscale‐distance‐tuned based on silica‐coated iron oxide nanoparticles are used to investigate how dipolar interactions affect magnetic resonance imaging (MRI) contrast. By varying shell thickness, researchers modulated dipolar interactions and observed an exponential increase in transverse relaxivity (r2) that ...

Quantitative accuracy of positron emission tomography/magnetic resonance and positron emission tomography/computed tomography for cervical cancer

open access: yesWorld Journal of Nuclear Medicine, 2018
With the spread of positron emission tomography/magnetic resonance (PET/MR), the question of comparability of studies becomes important. We aim to determine whether PET/MR and PET/computed tomography (PET/CT) are comparable for the case of cervical ...

Bidirectional ventricular tachycardia in cardiac sarcoidosis. [PDF]

open access: yes, 2016
A 73-year-old man with history of pulmonary sarcoidosis was found to have runs of non-sustained bidirectional ventricular tachycardia (BVT) with two different QRS morphologies on a Holter monitor.

A Minimally Invasive Framework Reveals Region‐Specific Cerebrovascular Remodeling in Aging Using Intravital Functional Ultrasound Imaging and Ultrasound Localization Microscopy (fUS‐ULM)

open access: yesAdvanced Science, EarlyView.
A high‐resolution intravital imaging platform combining functional ultrasound and localization microscopy enables longitudinal, minimally invasive assessment of cerebrovascular function in aging studies. The present investigation reveals aging‐related reductions in neurovascular coupling, arteriole‐to‐venule ratio and vascular density, introducing a ...

Prevalence and malignancy risk of focal colorectal incidental uptake detected by 18F-FDG-PET or PET/CT: a meta-analysis

open access: yesRadiology and Oncology, 2014
Background. The aim of the study was to meta-analyze published data about prevalence and malignancy risk of focal colorectal incidentalomas (FCIs) detected by Fluorine-18-Fluorodeoxyglucose positron emission tomography or positron emission tomography ...
