Artifacts in cranial MRI caused by extracranial foreign bodies and analysis of these foreign bodies
(Wolters Kluwer Medknow Publications, 2019)Purpose: the purpose of our study was to conduct a chemical analysis of extracranial foreign bodies (FBs) causing artifacts in cranial magnetic resonance imaging (MRI) and to investigate the association between chemical ... -
Assessment of breast mass morphology with diffusion-weighted MRI: Beyond apparent diffusion coefficient
(John Wiley and Sons Inc., 2018)Background: Diffusion-weighted imaging (DWI) is a noncontrast-enhanced MRI technique. There are new promising studies on the use of DWI as a part of the enhanced or unenhanced abbreviated breast MRI protocols. Purpose: To ... -
Can MRI-induced silastic casing tear be repaired without the need for cochlear implant replacement?
(Elsevier Ireland Ltd, 2019)Silastic magnet casing tear of cochlear implant (CI) due to magnetic resonance imaging (MRI) is an uncommon complication. We report repair of a case with magnet dislocation due to MRI-induced silastic casing tear without ... -
Comparison of thalamus volume on magnetic resonance and cadaveric section images
(Turkish Neurosurgical Soc, 2020)AIM: To measure and to compare the volume of thalamus using magnetic resonance imaging (MRI) and the anatomical sections. MATERIAL and METHODS: in this study, 13 brain specimens were used. First, the images were taken in ... -
Deep network-based comprehensive parotid gland tumor detection
(Elsevier, 2023)Rationale and Objectives: Salivary gland tumors constitute 2%-6% of all head and neck tumors and are most common in the parotid gland. Magnetic resonance (MR) imaging is the most sensitive imaging modality for diagnosis. ... -
The effect of gadolinium-based contrast agents on rat testis
(Wiley, 2018)Previous studies have reported that repeated administrations of linear gadolinium-based contrast agents lead to their accumulation in the brain and other tissues in individuals with normal renal functions. the purpose of ... -

(Aves, 2018)OBJECTIVE: This study aimed to evaluate the efficacy of magnetic resonance imaging (MRI) for diagnosing superior semicircular canal dehiscence (SSCD). MATERIALS and METHODS: the radiological records of patients who were ... -
Evaluation of cerebellar asymmetry in Alzheimer's disease: A stereological study
(Karger, 2009)Objectives: Alzheimer's disease (AD) is the most common cause of dementia and, as previous studies have indicated, degenerative changes in the cerebellum occur in AD. It is well known that the cerebellum does not have a ... -
The evaluation of eustachian tube paratubal structures using magnetic resonance imaging in patients with chronic suppurative otitis media
(Taylor & Francis Ltd, 2016)Conclusion Eustachian tube (ET) dysfunction, which plays a role in the pathogenesis chronic suppurative otitis media (CSOM), does not seem to be due to differences in paratubal structures. Objective the aim of this study ... -
Evaluation of vascular variations at cerebellopontine angle by 3D T2WI magnetic-resonance imaging in patients with vertigo
(Ios Press, 2017)BACKGROUND: Vascular loops of the anterior-inferior cerebellar artery (AICA) at the cerebellopontine angle (CPA) are considered related to auditory-vestibular symptoms. Clinical association of these anatomical aberrations, ... -
