Role of magnetic resonance imaging in the evaluation of the popliteus musclotendinous injuries as a part of the posterolateral corner injuries of the knee

ConclusionMRI imaging is crucial in the evaluation of the different sites and patterns of injuries of the popliteus musclotendinous complex when suspecting PLC injury.

The objective of this study was to assess respiratory muscle quality and function in DMD using magnetic resonance imaging and to determine the relationship to clinical respiratory function.MethodsIndividuals with DMD (n = 36) and unaffected controls (n = 12) participated in this cross sectional magnetic resonance imaging study. Participants underwent dynamic imaging of the thorax to assess diaphragm and chest wall mobility and chemical shift-encoded imaging of the chest and abdomen to determine fatty infiltration of the accessory respiratory muscles. Additionally, clinical pulmonary function mea...

Authors: Raisbeck LD, Diekfuss JA, Grooms DR, Schmitz R Abstract CONTEXT: Although the beneficial effects of using an external focus of attention are well documented in attainment and performance of movement execution, neural mechanisms underlying external focus' benefits are mostly unknown. OBJECTIVE: To assess brain function during a lower-extremity gross motor movement while manipulating an internal and external focus of attention. DESIGN: Cross-over study. SETTING: Neuroimaging center Participants: A total of 10 healthy subjects (5 males and 5 females) Intervention: Participants completed external a...

Contrast-enhanced ultrasound (CEUS) is an evolving diagnostic alternative to contrast-enhanced computed tomography, magnetic resonance imaging, and fluorescence angiography for the evaluation of vascular diseases. Microbubble contrast material allows imaging of blood flow in microvasculature beyond the resolution of standard imaging techniques and demonstrates potential for the evaluation of tissue perfusion. Several authors have investigated the application of CEUS in the evaluation of myocardial or skeletal muscle perfusion and tumor characterization.

Simon, Dan Madularu, Craig F. FerrisAbstractArginine vasopressin (AVP) is a chemical signal in the brain that influences cerebral vascular resistance and brain water permeability. Increases in AVP contribute to the pathophysiology of brain edema following traumatic brain injury (TBI). These effects are mediated through AVP V1a receptors that are expressed in cortical and subcortical brain areas. This exploratory study characterizes the ef...

FreyAbstractAnimal models reveal that deafferenting forelimb injuries precipitate reorganization in both contralateral and ipsilateral somatosensory cortices. The functional significance and duration of these effects are unknown, and it is unclear whether they also occur in injured humans. We delivered cutaneous stimulation during functional magnetic resonance imaging (fMRI) to map the sensory cortical representation of the intact hand a...

ConclusionsGrowth differentiation factor-15 can be used not only for the diagnosis of mitochondrial disease, but as an indicator of its acute exacerbation. A stroke-like episode of mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes reflects a drastic derangement of multiple amino acids. The involvement of aspartic acid in the episodes should be explored in future studies.

ConclusionsWithin the main limitation of this pilot study, that is, the small sample, it is possible to state that cephalometric measurements on 3T-MRI seem to possess adequate reliability and repeatability and that they show satisfying agreement with values measured on CBCTs. An MRI examination does not expose patients to ionizing radiation and could provide an alternative to CBCT for three-dimensional cephalometrics in the future.
