BACKGROUND AND PURPOSE Signs suggestive of unexpected dural venous sinus thrombosis are detectable on routine MR imaging studies without MRV. We assessed performance characteristics and interrater reliability of routine MR imaging for the diagnosis of dural venous sinus thrombosis, focusing on the superior sagittal, transverse, and sigmoid sinuses. MATERIALS AND METHODS This case series inclu...

The human roseoloviruses human herpesvirus 6A (HHV-6A), HHV-6B, and HHV-7 comprise the Roseolovirus genus of the human Betaherpesvirinae subfamily. Infections with these viruses have been implicated in many diseases; however, it has been challenging to establish infections with roseoloviruses as direct drivers of pathology, because they are nearly ubiquitous and display species-specific tropism...

We formulate and solve a generalized inverse Navier-Stokes problem for the joint velocity field reconstruction boundary segmentation of noisy flow images. To regularize we use Bayesian framework with Gaussian random fields. This allows us to estimate uncertainties unknowns by approximating their posterior covariance quasi-Newton method. first test method synthetic images 2D flows observe that s...

The monitoring, reporting and verification (MRV) of soil organic carbon (SOC) sequestration following management changes is complex due to the multitude influencing factors related ecosystem processes but also (socio-)economic or legal requirements. Several protocols for MRV applications have been published. In this chapter we will provide an overview about available systems their advantages li...

BACKGROUND AND PURPOSE Little is known about age-related changes in posterior fossa venous anatomy on 2D time-of-flight MR venography (MRV) or about artifacts that limit its accuracy in diagnosing venous occlusive disease. We evaluated pediatric appearances of posterior fossa venous drainage. METHODS One hundred and eight children with normal MR imaging or minimal congenital anomalies underwe...

Marine riparian areas and coastal vegetation are essential important to the marine ecosystem, although their interactions functions still unknown ignored in ecological studies integrated management planning. In southeastern Brazil, allochthonous resources derived from Atlantic rainforests bordering rocky shores have been observed abundance together with shallow subtidal reef benthos. this study...

A 50 year old male with obstructive sleep apnea developed de novo, daily, intense, continuous, left side pounding headache with superimposed stabbing pains, fluctuating in severity. Headache was associated with ptosis of the left eye, left hypoglossal palsy and eventual tongue hemiatrophy, in the absence of papilledema. His Brain and neck imaging procedures (MRI, MRA, MRV) and a left temporal a...
