Femur osteoid osteoma in children: are there location-dependent differences in MRI findings?
Pediatr Radiol
January 2025
Department of Radiology, Children's Hospital of Philadelphia, 3401 Civic Center Blvd, Philadelphia, PA, 19104, USA.
Background: Osteoid osteomas are most commonly found in the femur and preferentially affect the pediatric population. Magnetic resonance imaging (MRI) findings of femoral osteoid osteomas are not well described.
Objective: To systematically characterize pretreatment MRI findings of clinically confirmed femur osteoid osteomas in children and determine location-dependent differences.
Incremental Value of Shear Wave Elastography and Contrast-Enhanced Ultrasound in the Differential Diagnosis of Breast Non-Mass-Like Lesions.
Int J Womens Health
December 2024
Department of Ultrasound Imaging, The First Affiliated Hospital of Wenzhou Medical University, WenZhou, ZheJiang, 325000, People's Republic of China.
Objective: To analyse the parameters of shear wave elastography (SWE) and contrast-enhanced ultrasound (CEUS) in breast non-mass-like lesions (NMLs) and to evaluate the added diagnostic value of SWE and CEUS when combined with B-mode ultrasound (US) for differentiating NMLs.
Methods: A total of 118 NMLs from 115 patients underwent US, SWE, and CEUS examinations. The SWE parameter with the highest areas under the receiver operating characteristic (ROC) curves (Az) and independent variables of CEUS obtained by logistic regression were used to adjust the BI-RADS-US (Breast Imaging Reporting and Data System for Ultrasound) classification.
Magnetic resonance imaging characteristics of ovarian torsion: insights into diagnostic features.
Abdom Radiol (NY)
November 2024
Bezmiâlem Vakıf Üniversitesi, Istanbul, Turkey.
Purpose: We aimed to describe the magnetic resonance imaging (MRI) features of adnexal torsion, additional radiological findings and apparent diffusion coefficient (ADC) measurements of the affected and non-affected ovaries.
Methods: We retrospectively examined the MRI of 34 torsed adnexa of 34 cases. We specifically examined the peripherally displaced follicle sign, stromal edema, lack of stromal contrast enhancement, follicular rim sign, T2 hypointense rim sign, uterine deviation, adnexal displacement, whirlpool sign, T2 hypointense dot sign, and tubal thickening.
MRI differentiation of CNS fungal infections: correlating imaging features with microbiological and histopathological findings.
Neuroradiology
November 2024
Department of Radiology, Aga Khan University Hospital, Aga Khan University, Karachi Stadium Road, P.O. Box 3500, Karachi, 74800, Pakistan.
Article Synopsis
- The study investigates how magnetic resonance imaging (MR) can help identify the specific types of fungi responsible for central nervous system (CNS) infections, comparing MR findings with microbiology and histopathology results.
- A retrospective analysis of 50 patients revealed that Aspergillus spp. was the most common cause of infection, with specific MR features like pseudo-tumoral mass behavior linked to Aspergillus and meningitis associated with yeast infections.
- The research suggests that certain MR imaging characteristics, especially dot-like foci, may indicate abscesses from dematiaceous molds, although the overall radiological features are generally non-specific.
Comprehensive multicentre retrospective analysis for predicting isocitrate dehydrogenase-mutant lower-grade gliomas.
Ann Clin Transl Neurol
November 2024
Department of Cerebrovascular Disease and Neurosurgery, Henan University People's Hospital, Henan Provincial People's Hospital, Zhengzhou, 450003, China.
Objective: To differentiate glioma grading and determine isocitrate dehydrogenase (IDH) mutation status, which are crucial for prognosis assessment and treatment planning in glioma patients.
Methods: This retrospective study included patients diagnosed with adult diffuse glioma from 1 January, 2018 to 31 July, 2023 in two independent institutions. It documented and analysed clinical and radiographic features.
