Compression Garment-induced Leg Changes Increase Hemodynamic Responses in Healthy Individuals

This study evaluated the morphological changes of the lower limb and associated hemodynamic responses to different lower-body compression pressures (COMPs) in physically active, healthy individuals at rest. Each of the 32 participants underwent three trials with three different degrees of lower-body compression applied: “Low” (2.2±1.4 mmHg), “Medium” (12.9±3.9 mmHg), and “High” (28.8±8.3 mmHg). In each COMP, a cross-sectional area of leg muscles (CSAmuscle), subcutaneous fat (CSAfat), superficial vessels (SupV), deep arteries (DA), and deep veins (DV) at the calf, knee, and thigh levels were measured using magnetic resonance imaging (MRI). Additionally, blood pressure (BP), heart rate (HR), cardiac output (CO), stroke volume (SV), and systemic vascular resistance (SVR) were measured using Doppler ultrasound (USCOM®). With High COMP, calf CSAmuscle and SupV were smaller (p

Ultrasound (US) neck and technetium (Tc)-99m-sestamibi planar scintigraphy were negative, but single photon emission computed tomography/computed tomography (SPECT/CT) demonstrated a tracer-avid retropharyngeal nodule compatible with parathyroid adenoma (PTA). A retrospective review of CT neck angiogram (CTA) and neck magnetic resonance imaging (MRI) performed 4 months earlier for stroke evaluation revealed arterial phase hyperenhancing retropharyngeal tissue, whic...

Duplex ultrasound examination, computed tomography scans, and magnetic resonance angiography have traditionally been used as noninvasive methods to assess carotid stenosis severity. The degree of stenosis in asymptomatic patients has often been used as the main criterion to assess risk for plaque embolization and stroke. There has been an effort to find alternate methods to assess vulnerable plaques. This has included many modalities, including magnetic resonance imaging and other ultrasound techniques.

UP TO 40% of all ischemic strokes are considered cryptogenic, implying a stroke without a definitive etiology.1,2 With a dearth of evidence-guided treatment strategies, the literature surrounding cryptogenic stroke is highly variable and not well-standardized. Even though existing guidelines do not specify the exact testing required, the cryptogenic stroke evaluation includes a variety of imaging modalities (eg, echocardiography, angiography, magnetic resonance imaging, carotid ultrasound) and laboratory investigations (eg, genetic testing, hypercoagulable disorder panels, erythrocyte sedimentation rate).

Conclusion: This network meta-analysis provides supporting evidence to the idea that DWI has a higher diagnostic value regarding ischemic stroke among MRI methods, and CTP has a poor diagnostic value among CT methods, which provide therapeutic considerations for Ischemic stroke intervention.

Conclusion: The present study suggests that lesion patterns observed from DWI of patients with PFO and SIAD might provide clues to the etiology of infarcts. Single lesions (cortical or subcortical) might be a typical feature of PFO associated strokes, while multiple lesions in one vascular territory might be a specific feature of SIAD associated strokes. Introduction Both patent foramen ovale (PFO) and spontaneous intracranial artery dissection (SIAD) are important stroke risk factors, especially in young and middle-aged adults (1–3). About 25% of patients with ischemic stroke are cryptogenic (4), and PFO is pr...

Conclusions: PMP and EMP were associated with stroke and recent cerebrovascular events (DWI+) but only PMP were also associated with ongoing (MES+) thrombo-embolic activity suggesting a differential biomarker potential for EMP to index cerebral ischaemia while PMP may predict on-going thrombo-embolic activity.Cerebrovasc Dis Extra 2019;9:9 –18

Magnetic resonance imaging is the gold standard technique in establishing the diagnosis of neonatal arterial ischemic stroke (NAIS). The diagnostic value of cranial ultrasound scanning in this clinical context is controversial. We aimed to assess the current sensitivity of the cranial ultrasound scan (CUS) in detecting NAIS, as this issue has not been well described in the literature. Newborns with NAIS diagnosed by magnetic resonance imaging between 2010 and 2016 were included. All CUSs were blindly analyzed retrospectively by a neonatologist expert in neuroimaging and compared with the findings of non-expert evaluators r...
