The benefits of combined deferoxamine (DFO) and deferiprone (L1) chelation therapy, focusing on reducing myocardial iron loading, have been widely reported. Herein, we present the efficacy of combined chelation and its effects on iron load indices. Five thalassemia major (TM) patients who were undergoing chelation monotherapy with DFO were enrolled. Inclusion criteria were magnetic resonance imaging (MRI) T2* values, indicating serious heart and/or liver transfusional hemosiderosis. Combined therapy was started with the same dose of DFO and the addition of L1. The MRI T2* studies were repeated 18 months later. An Echo-Doppler study was performed in order to further evaluate the left ventricular (LV) systolic function. Within the 18 months' follow-up period, there was a significant statical decrease in mean serum ferritin levels. All patients increased their MRI T2* liver values, while two patients with very low MRI T2* also increased their myocardial values. The MRI ejection fraction (EF) and Echo-Doppler study measurements confirmed the improvement of systolic function. No adverse effects were reported. Combined L1 and DFO therapy seems to be effective in reducing iron excess in organ iron overloaded thalassemic patients. Magnetic resonance imaging can accurately quantify iron load, while echocardiography remains a reliable monitoring technology.

Purpose: This study proposes a novel, contrast-free Magnetic Resonance Fingerprinting (MRF) method using balanced Steady-State Free Precession (bSSFP) sequences for the quantification of cerebral blood volume (CBV), vessel radius (R), and relaxometry parameters (T , T , T *) in the brain.
Methods: The technique leverages the sensitivity of bSSFP sequences to intra-voxel frequency distributions in both transient and steady-state regimes. A dictionary-matching process is employed, using simulations of realistic mouse microvascular networks to generate the MRF dictionary.

To compare 1D (linear) tumor volume calculations and classification systems with 3D-segmented volumetric analysis (SVA), focusing specifically on their effectiveness in the evaluation and management of NF2-associated vestibular schwannomas (VS). VS were clinically followed every 6 months with cranial, thin-sliced (< 3 mm) MRI. We retrospectively reviewed and used T1-weighted post-contrast enhanced (gadolinium) images for both SVA and linear measurements.

Objectives: To investigate the impact of compressed sensing - sensitivity encoding (CS-SENSE) acceleration factor on the diagnostic performance of magnetic resonance imaging (MRI) within standard female pelvis protocol in patients with endometrial cancer.
Methods: T2-weighted turbo spin echo (TSE) sequence from standard female pelvic MRI protocol was chosen due to its long acquisition time and essential role in the evaluation of morphological characteristics of the female pelvic anatomical structures. Fully sampled reference scans and multiple prospectively 2x to 5x under-sampled CS-SENSE scans were acquired.

Objective: After a recent small subcortical infarct (RSSI), some patients develop perilesional or remote hyperintensities ('caps/tracks') to the index infarct on T2/FLAIR MRI. However, their clinical relevance remains unclear. We investigated the clinicoradiological correlates of 'caps/tracks', and their impact on long-term outcomes following RSSI.

Background: The presence of diffuse brain damage in normal-appearing white matter (NAWM) and gray matter (NAGM) in neuromyelitis optica spectrum disorder (NMOSD) remains controversial. We aimed to address this controversy by applying a multiparametric MRI approach. Additionally, the association between MRI metrics and clinical variables was explored.
