Article Synopsis
- * Out of 85 analyzed videos, the average content score was low, with significant gaps in crucial information such as disease progression and the importance of screening for related health issues.
- * The overall quality of the videos was rated as partially sufficient, with better ratings for videos from recognized sources, particularly in terms of transparency regarding sponsorship.
Purpose: To develop a novel signal representation for balanced steady state free precession (bSSFP) displaying its T independence on B and on magnetization transfer (MT) effects.
Methods: A signal model for bSSFP is developed that shows only an explicit dependence (up to a scaling factor) on E (and, therefore, T) and a novel parameter c (with implicit dependence on the flip angle and E). Moreover, it is shown that MT effects, entering the bSSFP signal via a binary spin bath model, can be captured by a redefinition of T and, therefore, leading to modification of E, resulting in the same signal model.

Background: Simultaneous positron emission tomography (PET) and magnetic resonance imaging (MRI) is a novel hybrid imaging method integrating the advances of morphological tissue characterization of MRI with the pathophysiological insights of PET applications.
Aim: This study evaluated the use of simultaneous 18-FDG PET/MR imaging for characterizing atherosclerotic lesions in lower extremity arterial disease (LEAD).
Methods: Eight patients with symptomatic stenoses of the superficial femoral artery (SFA) under simultaneous acquisition of 18-FDG PET and contrast-enhanced MRI using an integrated whole-body PET/MRI scanner.
Purpose: Determine the correct mathematical phase description for balanced steady-state free precession (bSSFP) signals in multi-compartment systems.
Theory And Methods: Based on published bSSFP signal models, different phase descriptions can be formulated: one predicting the presence and the other predicting the absence of destructive interference effects in multi-compartment systems. Numerical simulations of bSSFP signals of water and acetone were performed to evaluate the predictions of these different phase descriptions.
