Juvenile idiopathic arthritis of the knee: is contrast needed to score disease activity when using an augmented MRI protocol comprising PD-weighted sequences?

Objective: To compare unenhanced versus enhanced knee joint magnetic resonance imaging (MRI) to assess disease activity of juvenile idiopathic arthritis (JIA).

Methods: Fifty-three knee joint MRI examinations were performed on a 3-Tesla system in 27 patients (age: 11.40 ± 3.

Interventional Radiology Options after Visceral Surgery.

Background: Postoperative management of patients undergoing visceral surgery can present challenging clinical situations with significant morbidity and mortality. Interventional radiological techniques offer quick, safe, and effective minimally invasive treatment options in the postoperative management of visceral surgery.

Summary: Most commonly done procedures include - but are not limited to - fluid or abscess drainage, biliary diversion, bleeding embolization, and re-canalization of a thrombosed vessel.

25 years of experience with transjugular intrahepatic portosystemic shunt (TIPS): changes in patient selection and procedural aspects.

Background: TIPS is an established treatment for portal hypertension. The aim was to analyze how patient selection for TIPS implantation and procedural aspects have changed over 25 years. Routinely collected demographic, clinical, laboratory, and procedural data of 835 patients treated with TIPS in a single center were used.

Osteoid osteoma: treatment outcome and long-term follow-up after MRI-guided laser ablation.

Background: Aim of this study was to investigate short-term and long-term treatment outcome, complication rates, and patient satisfaction after MRI-guided laser ablation (LA) of osteoid osteoma (OO).

Methods: Thirty-five patients with OO in typical and atypical localizations were treated by MRI-guided LA with MRI thermometry in an open 1.0 T system.

Duodenal tropism of SARS-CoV-2 and clinical findings in critically ill COVID-19 patients.

Purpose: Duodenal involvement in COVID-19 is poorly studied. Aim was to describe clinical and histopathological characteristics of critically ill COVID-19 patients suffering from severe duodenitis that causes a significant bleeding and/or gastrointestinal dysmotility.

Methods: In 51 critically ill patients suffering from SARS-CoV-2 pneumonia, severe upper intestinal bleeding and/or gastric feeding intolerance were indications for upper gastrointestinal endoscopy.
