Anatomical Characteristics of Cervicomedullary Compression on MRI Scans in Children with Achondroplasia.

This retrospective study assessed anatomical characteristics of cervicomedullary compression in children with achondroplasia. Twelve anatomical parameters were analyzed (foramen magnum diameter and area; myelon area; clivus length; tentorium and occipital angles; brainstem volume outside the posterior fossa; and posterior fossa, cerebellum, supratentorial ventricular system, intracranial cerebrospinal fluid, and fourth ventricle volumes) from sagittal and transversal T1- and T2-weighted magnetic resonance imaging (MRI) scans from 37 children with achondroplasia aged ≤ 4 years (median [range] 0.8 [0.

A VR neurointerventional setup for catheter-based interventions focusing on visualizing the risk of radiation.

Interventional neuroradiologists carry out their minimally-invasive procedure by using X-rays within the setup of a Bi-plane Digital Subtraction Angiography. This work provides an immersive virtual reality (VR) environment where the physicians can perform an simulated catheter-based intervention. Since radiation is invisible, the risk of radiation exposure can be enhanced virtually.

Calculation of virtual 3D subtraction angiographies using conditional generative adversarial networks (cGANs).

Objective: Subtraction angiographies are calculated using a native and a contrast-enhanced 3D angiography images. This minimizes both bone and metal artifacts and results in a pure image of the vessels. However, carrying out the examination twice means double the radiation dose for the patient.

[Cardiovascular prevention in Saxony-Anhalt : Necessity and new perspectives].

Cardiovascular risk factors (high blood pressure, smoking, overweight, type 2 diabetes, dyslipidemia, physical inactivity) substantially rise with increasing age, particularly after middle age, whereby women are affected to a much greater extent. In the population of Saxony-Anhalt the prevalence of cardiovascular risk factors is clearly increased and the population structure in Saxony-Anhalt is particularly characterized by a high average age as well as high morbidity and mortality rates due to cardiovascular diseases. Saxony-Anhalt therefore provides a model character for the demographic development in Europe.
