Duplex Hemodynamic Parameters of Both Superior and Inferior Thyroid Arteries in Evaluation of Thyroid Hyperfunction Disorders.

Background: Thyrotoxicosis may be caused by Graves' disease or destructive thyroiditis. Differentiation between causes of thyrotoxicosis is crucial as management will differ. Technetium (Tc)-pertechnetate thyroid scintigraphy is currently the gold standard for this purpose, however, is expensive and uses ionizing radiation.

Productivity of 18F-FDG-PET/CT Diagnostic Tool in the Management of Pediatric Lymphoblastic Lymphoma.

Background: Lymphoblastic lymphoma (LL) comprises approximately 20% of childhood non-Hodgkin lymphoma (NHL); however, few studies had investigated the role of 18F-FDG-PET/CT in pediatric LL patients. We aim in this study to assess the role of 18F-FDG-PET/CT in the initial staging of newly diagnosed pediatric patients with LL as well as in the assessment of response after induction chemotherapy.

Patients And Methods: A prospective study enrolled biopsy proven newly diagnosed pediatric LL patients presenting in the Children Cancer Hospital Egypt (CCHE) during the period from October 2014 to October 2016.
