Gadoxetic Acid-Enhanced MRI in Differentiating Focal Nodular Hyperplasia from Hepatocellular Adenoma in Children.

Objective: To investigate the diagnostic performance of Gd-EOB-enhanced magnetic resonance imaging (MRI) for distinguishing focal nodular hyperplasia (FNH) from hepatocellular adenoma (HCA) in children.

Methods: Twenty-two patients (6 with HCA and 16 with FNH) were retrospectively included in this study. After qualitative analyses of MRI, quantitative analyses were performed by calculating the relative signal intensity ratios (SIR) between lesion and liver parenchyma both on precontrast and hepatobiliary phase images.

Multimodal ultrasonography evaluation in thyroid nodule characterization: what is the ideal algorithm?

Aims: The aim of this study is to investigate the diagnostic performances of Ultrasonography (US), Shear-wave Elastography (SWE), and Superb Microvascular Imaging (SMI) findings in the diagnosis of malignant thyroid nodules (MTNs) and to determine the US algorithm with the best diagnostic performance.

Material And Methods: Eighty-one nodules in 77 patients who had underwent multimodal US with biopsy results, were evaluated. Echogenicity, nodule components, contours, presence and type of calcification, and size were analyzed with US.

Morphometric Shape Analysis of Corpus Callosum in Children With Down Syndrome.

Down syndrome (DS) is characterized by varying degrees of mental retardation and delay in neurocognitive functions. Herein, we analyzed the morphometric shape of the corpus callosum (CC) in children with DS. Twenty-three DS cases underwent magnetic resonance imaging and have grossly normal CC, and 23 control group cases were included in this retrospective study (2012-2020).

Comparison of severity and complication rates of acute cholecystitis during pandemic and pre-pandemic periods?

Background: Cancellations of surgeries for elective cases and late admissions of symptomatic cases during the pandemic period might have increased the number of cases of acute cholecystitis and its complications.

Purpose: To compare the severity of acute cholecystitis and complication rates during the pandemic and pre-pandemic periods.

Material And Methods: We evaluated the computed tomography (CT) findings observed for the diagnosis of complications for both acute simple and acute complicated cholecystitis during both the pandemic and pre-pandemic periods.

Corpus callosum in schizophrenia with deficit and non-deficit syndrome: a statistical shape analysis.

Background: The corpus callosum (CC) is the most targeted region in the cerebrum that integrates cognitive data between homologous areas in the right and left hemispheres.

Aims: Our study used statistical analysis to determine whether there was a correlation between shape changes in the CC in patients with schizophrenia (SZ) (deficit syndrome (DS) and non-deficit syndrome (NDS)) and healthy control (HC) subjects.

Methods: This study consisted of 27 HC subjects and 50 schizophrenic patients (20 with DS and 30 with NDS).

Superb Microvascular Imaging in Assessment of Synovitis and Tenosynovitis in Juvenile Idiopathic Arthritis.

The aim of this study is to evaluate the diagnostic utility of superb microvascular imaging (SMI) in assessment of synovitis/tenosynovitis in juvenile idiopathic arthritis in comparison to power Doppler ultrasound. Thirty juvenile idiopathic arthritis cases with active clinical findings and ultrasound features of effusion and/or tenosynovitis were further imaged with power Doppler and SMI. For classification of synovial inflammation, a semiquantitative scale (4 points) adopted by Outcome Measures in Rheumatology was used.

Diagnostic utility of superb microvascular imaging in depiction of corkscrew collaterals in Buerger's disease.

Purpose: To evaluate the corkscrew collaterals in Buerger's disease by superb microvascular imaging (SMI) and power Doppler ultrasonography (PDU).

Methods: We evaluated with SMI and PDU 14 patients with Buerger's disease in whom corkscrew collaterals had been identified on digital subtraction angiography (DSA). Corkscrew collaterals were classified on DSA and PDU based on their size and morphology.

Statistical shape analysis of corpus callosum in restless leg syndrome.

Objectives: In this study we aimed to investigate corpus callosum shape differences between restless leg syndrome patients and healthy controls, and to determine whether disease severity and duration are indicators for corpus callosum deformation in RLS patients.

Methods: This study was conducted using the magnetic resonance imaging scans of 33 restless leg syndrome patients and 33 control subjects. Landmarks were marked on the digital images and callosal landmark coordinate data were used to assess shape difference by performing Generalized Procrustes analysis.

Congenital arteriovenous fistula between descending aorta and the left innominate vein.

Thoracic aortocaval fistulae are rare entities where a direct shunt between thoracic arteries and systemic veins is seen. They can be traumatic or congenital in origin. Congenital thoracic aortocaval fistulae usually involve descending aorta and azygos, hemiazygos systems.
