Accuracy of imaging of BI-RADS 4 subcategorizations in breast lesion diagnosis: Radiologic-pathologic correlation.

Objectives: To correlate breast imaging-reporting and data system (BI-RADS) category 4 lesions with histopathology results to assess the accuracy of subcategorization.

Methods: A retrospective study was carried out from September 2021 to June 2022. A total of 247 breast lesions were reviewed categorized as BI-RADS 4 using ultrasound (US) and digital mammography.

Approach to Thyroid Nodules: Diagnosis and Treatment.

Thyroid nodules (TNs) are prevalent and found in up to 50% of individuals. While most TNs are benign, some can be malignant. The evaluation of TNs is crucial to rule out malignancy and identify those requiring surgical intervention.

Exploring Early Childhood Autism Spectrum Disorders: A Comprehensive Review of Diagnostic Approaches in Young Children.

Autism spectrum disorders (ASD) encompass a diverse range of developmental disabilities characterized by pervasive deficiencies in socialization, communication, and the manifestation of behavioral issues. This review aims to clarify the diagnostic criteria for ASD, explore available diagnostic tools, evaluate biomedical examinations facilitating ASD diagnosis, and discuss the approach to screening assessments for ASD. ASDs are prevalent conditions, with a globally estimated prevalence of 7.

Does intravoxel incoherent motion reliably stage hepatic fibrosis, steatosis, and inflammation?

Objective: To investigate the usefulness of intravoxel incoherent motion (IVIM) in determining the severity of hepatic fibrosis, steatosis, and inflammation in patients with chronic liver disease.

Methods: Forty-nine patients who had liver MRI with IVIM sequence and liver biopsy within three months of MRI were enrolled. A reviewer, blinded to histology, placed regions of interest of 1-2 cm in the right liver lobe.

Comparison of the accuracy of diffusion-weighted imaging versus dynamic contrast enhancement magnetic resonance imaging in characterizing focal liver lesions.

Objective: The aim of this study was to compare the accuracy of liver magnetic resonance imaging (MRI) diffusion-weighted imaging (DWI) versus dynamic contrast enhancement (DCE) versus DWI and DCE in characterizing benign versus malignant lesions and in making correct diagnosis of focal liver lesions.

Methods: Sixty-six adult patients with 115 lesions were evaluated by 2 readers for differentiating benign versus malignant lesions and for lesion diagnosis. The readers evaluated the lesions using unenhanced MRI with DWI and, 4 weeks later, using MRI with DCE and, subsequently, using MRI and DCE with DWI.
