Early Recurrence Detection of Glioma Using 18 F-Fluorocholine PET/CT : GliReDe Pilot Study.

Objective: The aim of this study was to analyze the usefulness of 18 F-fluorocholine PET/CT in the early diagnosis of tumor recurrence, increasing the diagnosis confidence of MRI.

Methods: Patients with a previous gross total resection of glioma and the first suspicious or doubtful for recurrence MRI were prospectively included and subjected to 18 F-fluorocholine PET/CT. An independent and combined assessment of 18 F-fluorocholine PET/CT and multimodal MRI was performed classifying the studies as positive or negative for tumor recurrence.

Cerebrovascular disease in patients with COVID-19: neuroimaging, histological and clinical description.

Since the appearance of the first case of coronavirus disease 2019 (COVID-19) a pandemic has emerged affecting millions of individuals worldwide. Although the main clinical manifestations are respiratory, an increase in neurological conditions, specifically acute cerebrovascular disease, has been detected. We present cerebrovascular disease case incidence in hospitalized patients with SARS-CoV-2 infection.

FuMeGA Criteria for Visual Assessment of Postoperative 18F-Fluorocholine PET in Patients With Glioma.

Postoperative assessment is crucial in the imaging follow-up and prognosis in patients with glioma. Whereas grade of resection is defined attending to the gadolinium enhancement in early postoperative MRI, no metabolical criteria exist for postoperative PET interpretation. Based on our prospective and multicenter FuMeGA (Functional and Metabolic Glioma Analysis) ongoing study, we propose criteria for the visual interpretation of F-fluorocholine PET scans in patients undergoing brain tumor resection.

Analysing the integration of MR images acquired in a non-radiotherapy treatment position into the radiotherapy workflow using deformable and rigid registration.

Aim: Our aim was to analyse the feasibility of integrating an MRI acquired in a non-radiotherapy set-up into the prostate cancer radiotherapy workflow.

Material And Methods: The MRIs of 15 prostate cancer patients, acquired with a flat table-top (MRI-flat), and with a curved tabletop (MRI-curve) were analysed. MRIs were rigidly (RIR) and non-rigidly registered (DIR) with CT images.

[Giant racemose subarachnoid and intraventricular neurocysticercosis: A case report].

Neurocysticercosis is the most frequent parasitic disease of the central nervous system. It is caused by the larvae of Taenia solium, which can affect different anatomical sites. In Spain there is an increasing prevalence mainly due to immigration from endemic areas.
