How to Improve the Management of Acute Ischemic Stroke by Modern Technologies, Artificial Intelligence, and New Treatment Methods.

Stroke remains one of the leading causes of death and disability in Europe. The European Stroke Action Plan (ESAP) defines four main targets for the years 2018 to 2030. The COVID-19 pandemic forced the use of innovative technologies and created pressure to improve internet networks.

Percutaneous Computed Tomography-Guided Thermal Ablation of Pulmonary Osteosarcoma Metastases in Children.

Introduction: The role of percutaneous thermal ablation as a minimally-invasive treatment has not been evaluated in children under 18 years of age with pulmonary osteosarcoma metastases.

Methods: This was a retrospective review of children treated with percutaneous thermal ablation for pulmonary osteosarcoma metastasis after prior surgical metastasectomy and chemotherapy. Selection criteria included number of pulmonary nodules <5 and nodule size smaller than 2 cm.

Percutaneous osteosynthesis in the pelvis in cancer patients.

Purpose: Screw fixation (osteosynthesis) can be performed percutaneously by interventional radiologists. We report our experience in cancer patients.

Material/methods: We retrospectively reviewed all cases of percutaneous osteosynthesis (PO) of the pelvic ring and proximal femur performed in our hospital.

GEP-NETS update: Interventional radiology: role in the treatment of liver metastases from GEP-NETs.

Neuroendocrine tumors from gastro-pancreatic origin (GEP-NET) can be responsible for liver metastases. Such metastases can be the dominant part of the disease as well due to the tumor burden itself or the symptoms related to such liver metastases. Intra-arterial therapies are commonly used in liver only or liver-dominant disease and encompass trans-arterial chemoembolization (TACE), trans-arterial embolization (TAE), and radioembolization (RE).

Value of spontaneous hyperdensity of cerebral venous thrombosis on helical CT.

Background: Excluding a cerebral venous thrombosis (CVT) through imaging is a frequent request in the emergency setting. This assessment often starts by an unenhanced brain computed tomography (CT).

Purpose: Re-evaluate the value of spontaneous hyperdensity of CVT on helical unenhanced brain CT.
