Assessment of knee cartilage using accelerated 3 T MRI: Evaluation of an isotropic 3D fast spin-echo sequence (CUBE) with compressed sensing technique.

Purpose: Compressed Sensing (CS) is an emerging technique to accelerate MRI acquisitions. The aim of this study was to assess the reliability and accuracy of cartilage thickness measurements in the knee using a CS-enabled isotropic 3D Fast Spin-Echo (FSE) sequence on a 3-T MRI scanner.

Methods: Twenty-eight tibial condyle sections were collected from 14 adult patients who underwent total knee arthroplasty.

Development of a cost-effective 3D-printed MRI phantom for enhanced teaching of system performance and image quality concepts.

Purposes: This research highlights the need for affordable phantoms for MRI education. Current options are either expensive or limited. A phantom, easy to manufacture and distribute, is proposed to demonstrate various pedagogical concepts, aiding students in understanding MRI image quality concepts.

Narrative review of tissue-mimicking materials for MRI phantoms: Composition, fabrication, and relaxation properties.

Introduction: Tissue-mimicking materials (TMMs) are now essential reference objects for quality control, development and training in all medical imaging modalities. This review aims to provide a comprehensive synthesis of materials used in the fabrication of TMMs for MRI phantoms, focusing on their composition, fabrication methods, and relaxation properties (T1 and T2).

Methods: A systematic review was conducted, covering articles published between 1980 and 2023.

High-fidelity anatomical phantoms for MRI practical training.

Introduction: Practical MRI training is essential for bridging the gap between complex theoretical knowledge and clinical applications. Traditional phantoms used in MRI, such as ACR phantoms, are valuable for illustrating system characterization methods but often lack the anatomical complexity required for realistic training. This study presents the development of high-fidelity anatomical phantoms designed specifically for practical MRI training.

Quantitative and qualitative evaluation of three MSCT for high resolution bone imaging.

Introduction: Strategies for achieving high resolution varies between manufacturers. In CT, the helical mode with narrow collimation has long been considered as the gold standard for high-resolution imaging. More recently, incremental modes with small dexels and focal spot, have been developed but have not been compared with helical acquisitions under optimal conditions.
