“…Furthermore, the device uses a manual rotating knob to adjust the tension of the connecting belt mechanically. If the patient is uncomfortable or needs to readjust the pressure during the examination process, the technician is required to return to their bedside to assist (13,14,(18)(19)(20)(21).…”

“…Until now, several clinical studies have confirmed that axial loading MRI could improve the accuracy of the diagnosis of lumbar spinal stenosis thus change the clinical treatment strategy (9)(10)(11)(12). Currently, the only device for axial loading MRI is the DynaWell L-Spine (DynaWell Diagnostics, NY, USA), which has some defects, including instability in exerting force, complex operation, and high cost (13,14). In an effort to address these deficiencies, we developed a new lumbar axial loading device.…”

Background: Axial loading magnetic resonance imaging (MRI) of lumbar spine is of great significance in the diagnosis of lumbar diseases. However, the axial loading device used in clinic is unique and has some defects. Therefore, we aimed to investigate the effect and examinee comfort of a new device for axial loading lumbar MRI in asymptomatic volunteers.Methods: A new axial loading MRI device for the lumbar spine was developed. A total of 30 asymptomatic individuals underwent conventional lumbar MRI and axial loading lumbar MRI sequentially. The dural sac cross-sectional area (DSCA), sagittal vertebral canal diameter (SVCD), and disc height (DH) at L3-4, L4-5, and L5-S1 before and after axial loading were compared by two experienced radiologists. Examinee comfort during the two examinations was assessed.Results: All 30 volunteers completed the examinations with the new device. No difference in examinee comfort was found between conventional and axial loading MRI. After axial loading, the DSCA, SVCD, and DH showed the largest decreases at L4-5 followed by L5-S1 and L3-4, with the decreases in DSCA and SVCD at L4-5 being significant (P<0.05). Definite imaging-diagnosable disc herniation or bulging was shown at three intervertebral disc levels of three participants. Conclusions:The new device could effectively implement axial loading of the lumbar spine without causing obvious discomfort for the examinee. The present study has demonstrated that significant changes occur in the lumbar spine of asymptomatic individuals after axial loading.

“…Specialists can assess the course of healing and adjust therapies by assessing bone marrow edema and monitoring its resolution. This method makes sure that treatment plans, including weight-bearing limitations or physical therapy, are modified as needed to improve recovery outcomes (Fiani, 2020). The field of medicine has given MRI integration into fracture care regimens a strong authorization.…”

The study emphasizes the advancement achieved through Magnetic Resonance Imaging (MRI) technology in identifying bone fractures, particularly in cases such as osteoporosis. The paper explores the utilization of MRI in examining bone health to determine fracture risks, particularly those caused by osteoporosis while identifying the limitations of Dual-Energy X-ray absorptiometry (DEXA) scans for comprehensive insights. As evident, the utilization of DEXA scans permits the measurement of Bone Mineral Density (BMD) and the identification of fracture susceptibility. However, the depth of information provided by DEXA scans falls short of that attainable through MRI scans. The researcher's strategy involves a comprehensive evaluation of methods for assessing bone health, encompassing the significance of BMD and the limitations associated with DEXA scans. Moreover, the study delves into the potential utilization of MRI in offering a holistic measurement of bone health and mitigating the risk of osteoporotic fractures. As revealed, MRI meticulously examines bone properties via a process involving magnetic manipulation of protons, creating cross-sectional images that offer unique insights into internal structure. MRI surpasses DEXA in detecting Osteoporotic Bone Fractures, offering a comprehensive understanding essential for treatment planning and patient recovery. Its early detection prevents complications and guides interventions effectively. This technique employs T1-weighted, T2-weighted, and proton-density imaging to analyze complex bone webs. Therefore, the researcher strongly recommends further research to harness MRI's evolving capabilities, enabling more accurate, individualized assessments of fracture risks and treatment strategies, ultimately enhancing fracture care with precise diagnoses and tailored approaches for improved health outcomes.

“…Vertical MRI (called "weightbearing MRI") have been used for two decades to study the effect of one's weight on one's joints [70]. Their use for functional imaging would allow researchers to differentiate the proper effect of the lying down position but the technology has not been used in this way up to now as the scanner's power is limited to 1.5T [73].…”

Swallowing is a complex function that relies on both brainstem and cerebral control. Cerebral neurofunctional evaluations are mostly based on functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), performed with the individual laying down; which is a non-ecological/non-natural position for swallowing. According to the PRISMA guidelines, a review of the non-invasive non-radiating neurofunctional tools, other than fMRI and PET, was conducted to explore the cerebral activity in swallowing during natural food intake, in accordance with the PRISMA guidelines. Using Embase and PubMed, we included human studies focusing on neurofunctional imaging during an ecologic swallowing task. From 5948 unique records, we retained 43 original articles, reporting on three different techniques: electroencephalography (EEG), magnetoencephalography (MEG) and functional near infra-red spectroscopy (fNIRS). During swallowing, all three techniques showed activity of the pericentral cortex. Variations were associated with the modality of the swallowing process (volitional or non-volitional) and the substance used (mostly water and saliva). All techniques have been used in both healthy and pathological conditions to explore the precise time course, localization or network structure of the swallowing cerebral activity, sometimes even more precisely than fMRI. EEG and MEG are the most advanced and mastered techniques but fNIRS is the most ready-to-use and the most therapeutically promising. Ongoing development of these techniques will support and improve our future understanding of the cerebral control of swallowing.
