Radiological and clinical signatures to differentiate hepatocellular carcinoma from hepatoblastoma in children older than 5 years of age: a feasibility study.

Background: Hepatoblastoma and hepatocellular carcinoma (HCC) are the most common primary malignant liver tumors in children. Although some characteristic imaging findings have been described in both hepatoblastoma and HCC, it is difficult to distinguish between these two tumors over the 5 years of age.

Objective: To investigate clinical and radiological findings that may help differentiate hepatoblastoma and HCC over 5 years of age.

Quantifying diversity and growth form distribution of scleractinian corals, in Mangrove Bay, El Qoseir, Egypt.

Background: Coral reefs provide habitat for approximately 25% of all extant marine species, including 845 species of scleractinian corals. These rich ecosystems are becoming increasingly degraded in many regions by a range of anthropogenic factors, including recurrent bleaching episodes associated with rising sea surface temperatures. Within the northern Red Sea, coral reef communities appear to be faring relatively better than global trends and continue to exhibit remarkable diversity and thermal tolerance.

Zero-echo time MRI: an alternative method for the diagnosis of urinary stones in children.

Objectives: To evaluate the potential of zero-echo time-magnetic resonance imaging (ZTE-MRI) in the assessment of urolithiasis and compare ZTE-MRI with computed tomography (CT) in pediatric patients.

Materials And Methods: This was a single-center, prospective cross-sectional study conducted between April 2023 and December 2023. 23 patients (12 girls, 11 boys; mean age: 12.

The role of malnutrition on outcomes of multisystem inflammatory syndrome in children (MIS-C) due to COVID-19.

Background: Malnutrition increases the complications and mortality in critically-ill children. We performed a retrospective analysis to define the impact of malnutrition on the outcomes of multisystem inflammatory syndrome in children (MIS-C) due to COVID-19.

Methods: Patients with MIS-C were evaluated for demographic features, anthropometric parameters, clinical findings and outcomes.

Radiomics in differential diagnosis of Wilms tumor and neuroblastoma with adrenal location in children.

Objectives: Machine learning methods can be applied successfully to various medical imaging tasks. Our aim with this study was to build a robust classifier using radiomics and clinical data for preoperative diagnosis of Wilms tumor (WT) or neuroblastoma (NB) in pediatric abdominal CT.

Material And Methods: This is a single-center retrospective study approved by the Institutional Ethical Board.

Imaging Features of Pediatric Sarcoidosis.

Sarcoidosis is a granulomatous inflammatory disease of uncertain cause. It occurs most commonly in young and middle-aged adults and less frequently in children; therefore, few data on pediatric sarcoidosis exist in the literature. The diagnosis and management of sarcoidosis remain challenging because of diverse and often nonspecific clinical and imaging findings.

Focal fatty sparing areas of the pediatric steatotic liver: pseudolesions on hepatobiliary phase magnetic resonance images.

Purpose: Focal fatty sparing in liver can be detected as hyperintense pseudolesions on hepatobiliary phase magnetic resonance imaging (MRI). Distinguishing these pseudolesions from liver lesions may make diagnosis challenging. The aim of this study was to evaluate the imaging features of fatty sparing areas on liver MRI in pediatric patients who have been administered gadoxetate disodium.

Many faces of torsion in pediatric female pelvis.

Pediatric patients of various ages, from infancy through adolescence, can have ovarian torsion. Torsion may not only be confined to the ovaries but may also involve the isolated cyst, tube, and even the uterus. In this pictorial review, we review the spectrum of torsion in pediatric (from infants to adolescents) female pelvis, emphasizing imaging methods.
