Evaluation of liver parenchyma with shear wave elastography in patients with rheumatoid arthritis receiving disease-modifying antirheumatic drug therapy.

Background: Methotrexate (MTX) and leflunomide (LEF) play fundamental roles in rheumatoid arthritis (RA) treatment and require proper monitoring of side effects. Concerns about MTX/LEF-related liver fibrosis (LF) in patients with RA remain unclear. This study investigated liver stiffness using two-dimensional shear wave elastography (2D-SWE) in RA patients undergoing disease-modifying antirheumatic drug (DMARD) therapy.

Evaluation of signal intensity changes in dentate nucleus and globus pallidus on magnetic resonance imaging after intrathecal gadolinium-based contrast agent administration.

Purpose: Gadolinium deposition has been reported in several normal anatomical structures in the brain after repeated administration of intravenous gadolinium-based contrast agents (GBCAs) used in magnetic resonance imaging (MRI). This study presents preliminary results to see if there is any gadolinium deposition in the dentate nucleus and globus pallidus after using intrathecal GBCAs.

Methods: Between November 2018 and November 2020, 29 patients who underwent intrathecal contrast-enhanced MR cisternography with the suspicion of rhinorrhea were included in this prospective study.

Evaluation of the thyroid gland vascularity during pregnancy using 2-dimensional color Superb Microvascular İmaging vascularization index technique.

Purpose: We aimed to investigate maternal thyroid parenchymal vascularity with 2-dimensional color superb microvascular imaging vascularization index (2D-cSMIVI) levels and thyroid gland volume in the first, second and third trimesters.

Methods: This longitudinal prospective study was carried out with participants selected from 30 healthy asymptomatic pregnant women. Ultrasonography (US) for the thyroid gland was performed in each trimester.

Assessment of lacrimal gland involvement in primary Sjögren's syndrome using gray-scale ultrasonography and shear wave elastography.

Objectives: The aim of this study was to assess lacrimal gland involvement in primary Sjögren's syndrome (pSS) using lacrimal gland gray-scale ultrasound (LGUS) and two-dimensional shear wave elastography (2D-SWE).

Methods: Eighty-five pSS patients with a mean age of 51.16 ± 10.

Can magnetic resonance imaging texture analysis change the breast imaging reporting and data system category of breast lesions?

Purpose: This study aimed to reveal magnetic resonance imaging (MRI) texture analysis (TA)'s contribution to categorizing breast lesions according to the Breast Imaging-Reporting and Data System (BI-RADS) lexicon.

Method: Two hundred and seventeen women with BI-RADS category 3, 4, and 5 lesions on breast MRI were included in the study. For TA, the region of interest was drawn manually to encompass the entire lesion on the fat-suppressed T2W and the first post-contrast T1W images.

Fetal Orbital Epidermal Cyst Pre-postnatal Imaging Findings: A Case Report and Literature Review.

Background: Fetal ultrasonographic evaluation is a routine part of pregnancy follow-up, and examination of orbital structures is also part of the routine evaluation. Although orbital developmental anomalies are common in the neonatal period, diagnosis in the intrauterine period is not common. To our knowledge, three cases with a diagnosis of congenital orbital epidermal cysts have been reported in the literature, and two of them had fetal imaging findings.

Diagnostic performance of gray-scale ultrasound and shear wave elastography in assessing salivary gland involvement in patients with primary Sjögren's syndrome.

Purpose: To investigate the diagnostic performance of gray-scale ultrasound (US) and shear wave elastography (SWE) for determining salivary gland involvement primary Sjögren's syndrome (pSS).

Methods: In this prospective study, the salivary glands of 72 healthy volunteers and 74 participants with pSS were examined by two blinded radiologists with consensus using gray-scale US and SWE. SWE parameters were compared between groups.

A different perspective on the dilemma of durotomy or duraplasty in Chiari type 1 malformation surgery.

Purpose: Symptomatic Chiari type 1 malformation (CIM) patients may elect to be treated; however, choosing the optimum surgical method remains problematic: posterior fossa decompression with duraplasty (PFDD) or without duraplasty (PFD). Many studies have compared these surgical methods from several perspectives. We looked at soft tissue density (STD) at the foramen magnum to add another perspective to the comparison of PFD with PFDD.

Giant Vertebral Artery Aneurysm in Behçet's Disease: A Rare Case and Review of the Literature.

Background: Behçet's disease is a chronic inflammatory disease that involves systemic organs and vascular structures. Arterial system involvement is rarer than the venous system, and it is one of the major causes of death. Vertebral artery (VA) involvement is rare and there are a limited number of reported cases in the literature.

The Coexistence of Two Different Epithelial Ovarian Tumors: A Rare Case.

Background: Epithelial tumors are the most common subgroup and are seen in 60-70% of all ovarian tumors. Serous cystadenoma and mucinous cystadenoma are the most common benign epithelial tumors. Serous cystadenomas are ovarian tumors with the highest bilateral incidence.

Fahr's disease associated with anaplastic ependymoma: a case report and review of the literature.

Fahr's disease, also known as familial idiopathic basal ganglia calcification or bilateral strio-pallido-dentate calcinosis, is a rare entity characterized by abnormal vascular calcium depositionin the thalamus, basal ganglia, cerebral cortex and the dentate nuclei of the cerebellum. Intracranial ependymomas comprise approximately 2% to 9% of all neuroepithelial tumors. It is reported that supratentorial ependymoma constitute 30% to 50% of all intracranial ependymal tumors.
