[Acute disseminated encephalomyelitis].

Background: Acute disseminated encephalomyelitis (ADEM) is a rare demyelinating disease that occurs predominantly in children. According to the guidelines, ADEM belongs to the myelin oligodendrocyte glycoprotein (MOG)-associated diseases and usually manifests after febrile infections (also after SARS-CoV-2) or postvaccinally.

Objectives: Incidence, course and clinical, and as well, as radiological features and new developments and treatment of ADEM.

Risk Factors for Restenosis After Stenting or Angioplasty of Vertebral Artery Origin : Results of Short-term and Long-term Follow-up.

Background And Purpose: Endovascular treatment represents a well-established therapeutic option in patients with vertebral artery origin (VAO) stenosis. Our aim was to determine which factors affect short- and long-term restenosis rates after endovascular VAO therapy.

Methods: We conducted a single center analysis of 52 patients (36 men; age 64 ± 9.

Workflow optimisation for multimodal imaging procedures: a case of combined X-ray and MRI-guided TACE.

This study presents a framework for workflow optimisation of multimodal image-guided procedures (MIGP) based on discrete event simulation (DES). A case of a combined X-Ray and magnetic resonance image-guided transarterial chemoembolisation (TACE) is presented to illustrate the application of this method. We used a ranking and selection optimisation algorithm to measure the performance of a number of proposed alternatives to improve a current scenario.

Heating and safety of a new MR-compatible guidewire prototype versus a standard nitinol guidewire.

Our purpose in this study was to examine heating of nitinol and polyetheretherketone (PEEK) guidewires during near-real-time MR imaging in an artificial vascular model an "aorta phantom". The first 100 cm of the nitinol- and PEEK-based guidewires both 145 × 0.08 cm were immersed in a saline-filled aorta phantom.

Liver fibrosis: how many samples in transjugular liver biopsy are sufficient? Histological vs. clinical value.

Purpose: Liver biopsy (LB) is a diagnostic procedure to obtain histological diagnosis, grading and staging in individuals with liver diseases. Most commonly LB is performed percutaneously. However, transjugular liver biopsy (TJLB) is considered as an alternative.
