Differentiating among early-stage parkinsonisms is a challenge in clinical practice. Quantitative MRI can aid the diagnostic process, but studies with singular MRI techniques have had limited success thus far. Our objective is to develop a multi-modal MRI method for this purpose. In this review we describe existing methods and present a dedicated quantitative MRI protocol, a decision model and a study design to validate our approach ahead of a pilot study. We present example imaging data from patients and a healthy control, which resemble related literature.

Background: Iron is vital for metabolism but can act as a catalyst for oxidative damage. Elevated brain iron, determined from biomarkers of iron (CSF ferritin and quantitative susceptibility mapping MRI) and from post-mortem measurement of brain iron, has been associated with accelerated cognitive decline in multiple Alzheimer's disease (AD) clinical, cohorts. These findings supported the hypothesis that treatment with the brain-permeable iron chelator deferiprone may be associated clinical benefit in AD.

Background: Recent preclinical studies have revealed a significant reduction in amyloid-β plaques and pro-inflammatory cytokines in Alzheimer's disease (AD) mouse models following low-dose radiation therapy (LDRT). This phase II, multicenter, prospective, single-blinded, randomized controlled trial (NCT05635968, funding from Korea Hydro & Nuclear Power: Grant No. A21IP11) aims to investigate the efficacy and safety of whole-brain LDRT in patients with AD.

The purpose of this study was to produce metabolite-specific T and concentration maps in a clinically compatible time frame. A multi-TE 2D MR spectroscopic imaging (MRSI) experiment (multi-echo single-shot MRSI [MESS-MRSI]) deployed truncated and partially sampled multi-echo trains from single scans and was combined with simultaneous multiparametric model fitting. It was tested in vivo for the brain in five healthy subjects.

Breast cancer continues to be a major health concern, and early detection is vital for enhancing survival rates. Magnetic resonance imaging (MRI) is a key tool due to its substantial sensitivity for invasive breast cancers. Computer-aided detection (CADe) systems enhance the effectiveness of MRI by identifying potential lesions, aiding radiologists in focusing on areas of interest, extracting quantitative features, and integrating with computer-aided diagnosis (CADx) pipelines.

Background: Luminal and hemodynamic evaluations of the cervical arteries inform the diagnosis and management of patients with cervical arterial disease.
Purpose: To demonstrate a 3D nonenhanced quantitative quiescent interval slice-selective (qQISS) magnetic resonance angiographic (MRA) strategy that provides simultaneous hemodynamic and luminal evaluation of the cervical arteries.
Study Type: Prospective.
