Experiences with patient-initiated follow-up supported by asynchronous telemedicine in spondyloarthritis: a mixed methods study.

Objectives: To evaluate the experiences of patients with spondyloarthritis (SpA) and their healthcare providers (HCPs) with patient-initiated follow-up (PIFU) supported by asynchronous telemedicine (TM) compared with their previous experiences with usual care, and to identify prerequisites for sustainable implementation of PIFU/TM.

Methods: Individual, semi-structured interviews were conducted with purposefully selected patients (n = 21) and HCPs (n = 9) who previously participated in the 'TeleSpA' randomised controlled trial and thematically analysed. PIFU/TM consisted of a once-yearly pre-planned physical visit with in-between remote monitoring at 6 months.

The Road to a Realistic 3D Model for Estimating R and R* Relaxation Versus Gd-DTPA Concentration in Whole Blood and Brain Tumor Vasculature.

Dynamic susceptibility contrast (DSC) MRI is commonly part of brain tumor imaging. For quantitative analysis, measurement of the arterial input function and tissue concentration time curve is required. Usually, a linear relationship between the MR signal changes and contrast agent concentration ([Gd]) is assumed, even though this is a known simplification.

Exploring the need for a preload on the estimation of permeability, vessel radius, and relative cerebral blood volume in MR vascular fingerprinting-based dynamic susceptibility contrast perfusion imaging.

Purpose: Dynamic susceptibility contrast (DSC) MRI is commonly part of the clinical brain tumor imaging protocol. Usually, a preload of contrast agent is administered to minimize contrast-leakage T effects. However, recent studies have indicated that with adaptation of scan parameters (in particular, low flip angle), a preload is not required.

Radiation Lobectomy in Adjunct to Double Vein Embolization to Reach Sufficient Future Liver Remnant in Patients with Colorectal Cancer Liver Metastases: A Case Series.

Purpose: To describe the outcome of radiation lobectomy (RL) after double vein embolization (portal vein embolization + hepatic vein embolization) for patients with insufficient future liver remnant growth.

Materials And Methods: All patients with insufficient FLR function (as determined by hepatobiliary scintigraphy (HIDA); < 2.7%/min/m) after double vein embolization who underwent RL between 2020 and 2023 were selected.
