Article Abstract
Bone and soft tissue pediatric sarcomas metastasize to the lungs, and computed tomography (CT) represents the diagnostic gold standard. We aimed to investigate the diagnostic accuracy of turbo inversion recovery magnitude (TIRM), inverted TIRM (inverted turbo inversion recovery magnitude [iTIRM]), and T1-weighted (T1w) controlled aliasing in parallel imaging results in higher acceleration (CAIPIRINHA) DIXON with water contrast for the diagnosis of lung metastases in children who underwent 18F-fluorydexoxyglucose-positron emission tomography/magnetic resonance ([18F]-FDG-PET/MR) for staging. TIRM showed the highest sensitivity (84.62%), whereas iTIRM and T1w had higher specificity (89.13% and 100%, respectively). Magnetic resonance imaging provides a good diagnostic performance for pulmonary metastases in children with sarcomas using both fluid sensitive and T1w sequences.

Background: Glial fibrillary acidic protein (GFAP) astrocytosis is a rare autoimmune encephalitis discovered in the last decade. The diagnosis depends on clinical symptoms, imaging, and antibody testing. However, most cases require several months or even longer to make a definite diagnosis.

Background: Multiple models intravoxel incoherent motion (IVIM) based F-fluorodeoxyglucose positron emission tomography-magnetic resonance(F-FDG PET/MR) could reflect the microscopic information of the tumor from multiple perspectives. However, its value in the prognostic assessment of non-small cell lung cancer (NSCLC) still needs to be further explored.
Objective: To compare the value of F-FDG PET/MR metabolic parameters and diffusion parameters in the prognostic assessment of patients with NSCLC.

Background: This study aimed to evaluate the diagnostic accuracy of [18F]FDG PET/MR versus [18F]FDG PET/CT in the thoracic staging of patients with non-small cell lung cancer (NSCLS).
Material And Methods: The Preferred Reporting Items for Systematic Reviews (PRISMA) were followed in conducting the present study. All available research was collected through Embase (Elsevier), PubMed, as well as Cochrane Library databases up to June 2021.

18F-FDG-PET/MR images, including DWI, of a 46-year-old male admitted to the Emergency Room of our tertiary center, who was suffering from diplopia, left orbital pain, and a headache for two weeks, demonstrated multiple hepatic nodules, a pancreatic mass, and skeletal metastases, in addition to thrombosis of the left cavernous sinus, thickening of the small intestine, and a large hepatic lesion identified at head and neck MR and whole-body CT, respectively. Hepatic and bone marrow biopsies revealed the diagnosis of Burkitt lymphoma. After four cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, methotrexate/ifosfamide, etoposide, and high dose cytarabine (R- CODOX-M/IVAC), a complete metabolic response occurred.
