Assessment of mitral valve regurgitation by cardiovascular magnetic resonance imaging

Nature Reviews Cardiology, Published online: 09 December 2019; doi:10.1038/s41569-019-0305-zIn this Consensus Statement, Garg and colleagues describe the current evidence on the use of cardiovascular magnetic resonance imaging for the assessment of mitral regurgitation, highlight its current clinical utility, and recommend a standardized imaging protocol and report.

Conclusion: The diagnosis of CMTX1 should be considered, even in female patients, when the disease presents with recurrent stroke-like symptoms and abnormal white matter signals on MRI. The puerperium after delivery may be one of the precipitating factors.

We present the case of an 8-month-old boy with the repeated recurrence of vesicles from the time of birth and who subsequently manifested psychomotor developmental delay. We retrospectively diagnosed the patient with congenital herpes simplex virus (HSV) infection. Computed tomography showed multiple calcifications in the periventricular white matter and thalami. The bilateral deep white matter showed an abnormally high signal intensity on T2-weighted magnetic resonance imaging. The patient required consecutive, suppressive therapy with valacyclovir to prevent the repeated recurrence of vesicles.

AbstractBackgroundThe purpose of this study is to investigate the performance of dual-layer detector spectral CT for iron deposition compared to magnetic resonance imaging (MRI) T2* imaging.MethodsThirty-one patients with a clinical history of myelodysplastic syndromes and aplastic anemia underwent liver and cardiac T2*-weighted unenhanced MRI on a three-tesla MRI scanner, and underwent unenhanced CT scan laterally on a 128-row spectral detector CT. R2* values of the liver, septal muscle, and paraspinal muscle were calculated. Attenuation differences ( ΔH) in the liver and myocardium were calculated between the lower...

AbstractRodent models are increasingly important in translational neuroimaging research. In rodent neuroimaging, particularly magnetic resonance imaging (MRI) studies, brain extraction is a critical data preprocessing component. Current brain extraction methods for rodent MRI usually require manual adjustment of input parameters due to widely different image qualities and/or contrasts. Here we propose a novel method, termed SHape descriptor selected Extremal Regions after Morphologically filtering (SHERM), which only requires a brain template mask as the input and is capable of automatically and reliably extracting the bra...

AbstractThe clinical pictures of essential tremor (ET) with resting tremor (rET) and tremor-dominant Parkinson ’s disease (tPD) are often quite mimic at the early stage, current approaches to the diagnosis and treatment therefore remain challenging. The regional homogeneity (ReHo) method under resting-state functional magnetic resonance imaging (rs-fMRI) would help exhibit the patterns in neural activity, which further contribute to differentiate these disorders and explore the relationship between symptoms and regional functional abnormalities. Sixty-eight Chinese participants were recruited, including 19 rET patien...

Brain computer interface (BCI)-based training is promising for the treatment of stroke patients with upper limb (UL) paralysis. However, most stroke patients receive comprehensive treatment that not only includes BCI, but also routine training. The purpose of this study was to investigate the topological alterations in brain functional networks following comprehensive treatment, including BCI training, in the subacute stage of stroke. Twenty-five hospitalized subacute stroke patients with moderate to severe UL paralysis were assigned to one of two groups: 4-week comprehensive treatment, including routine and BCI training (...

ConclusionsTo date, this is the first reported case where a patient underwent oblique lateral interbody fusion surgery in a left lateral decubitus position due to a left-sided inferior vena cava. This case demonstrates that carefully reading radiological results is important for operation planning and avoiding anatomical complications.
