Background Systematic evaluation of complex flow in the true lumen and false (TL, FL) is needed to better understand which patients with chronic descending aortic dissection (DAD) are predisposed complications. Purpose To develop quantitative hemodynamic maps from 4D MRI for evaluating TL FL characteristics. Study Type Retrospective. Population In all, 20 DAD (age = 60 ± 11 years; 12 male) (six medically managed type B AD [TBAD], 14 repaired A [rTAAD] now ascending graft [AAo] or elephant...
Shear wave elastography (SWE) is mainly used for stiffness estimation of large, homogeneous tissues, such as the liver and breasts. However, little known about its accuracy applicability in thin (∼0.5-2 mm) vessel walls. To identify possible performance differences among vendors, we quantified measured velocities obtained by commercial SWE implementations various vendors over different imaging depths a vessel-mimicking phantom. For reference, values cylindrical inclusions background...
To employ four-dimensional (4D) flow MRI to investigate associations between hemodynamic parameters with systolic anterior motion (SAM), mitral regurgitation (MR), stroke volume, and cardiac mass in patients hypertrophic cardiomyopathy (HCM).A total of 13 HCM (51 years ± 16 [standard deviation]; 10 men) 11 age-matched healthy control subjects (54 15; eight underwent 4D data analysis including calculation peak diastolic control-averaged left ventricular (LV) velocity maps quantify volumes...
Abstract Background Increased head and neck cancer (HNC) survival requires attention to long-term treatment sequelae. Irradiated HNC survivors have a higher ischemic stroke risk. However, the pathophysiology of radiation-induced vasculopathy is unclear. Arterial stiffness could be biomarker. This study examined alterations in intima-media thickness (IMT) stiffness-related parameters, shear wave (SWV) pulse velocity (PWV), irradiated compared control carotids unilateral patients. Methods...
With a growing, younger population of head and neck cancer survivors, attention to long-term side-effects prior, often radiotherapeutic, treatment is warranted. Therefore, we studied the cognitive effects in young adult patients irradiated for neoplasms (HNN).Young middle-aged adults with HNN (aged 18-40 years) treated unilateral irradiation ≥ 5 years before inclusion underwent cardiovascular risk neuropsychological assessments answered validated questionnaires regarding subjective...
To fully quantify arterial wall and plaque stiffness, acoustic radiation force impulse (ARFI)-induced wave-tracking along the entire vessel circumference is desired. However, attenuation guided wave behavior in thin walls limits to short trajectories. This study investigated potential of beam-steered ARFI extend group velocity estimation over a larger proportion compared conventional 0° ARFI-induced wave-tracking.Seven vessel-mimicking polyvinyl alcohol cryogel phantoms with various...
