This article describes a new method of the reconstruction of the lumen of hollow and tubular anatomical structures based on the application of polyurethane foam used in construction assembly. Preparations obtained by this method, are characterized by lightness, convenience of assembly and transportation. The making of such preparation does not require a lot of time. Preparations are successfully employed in anatomical museums and in the process of teaching. This method may also be employed for scientific purposes as well as in for realization of practical surgical tasks for removal of mucous membrane (demucosation) of the hollow organs.

An Artificial Intelligence-Based Automatic Classifier for the Presence of False Lumen Thrombosis After Frozen Elephant Trunk Operation.
Diagnostics (Basel)
December 2024
Translational Imaging Centre, Houston Methodist Research Institute, Houston, TX 77030, USA.
Objective: To develop an unsupervised artificial intelligence algorithm for identifying and quantifying the presence of false lumen thrombosis (FL) after Frozen Elephant Trunk (FET) operation in computed tomography angiographic (CTA) images in an interdisciplinary approach.
Methods: CTA datasets were retrospectively collected from eight patients after FET operation for aortic dissection from a single center. Of those, five patients had a residual aortic dissection with partial false lumen thrombosis, and three patients had no false lumen or thrombosis.

Rationale And Objectives: To evaluate and compare image quality of different energy levels of virtual monochromatic images (VMIs) using standard versus strong deep learning spectral reconstruction (DLSR) on dual-energy CT pulmonary angiogram (DECT-PA).
Materials And Methods: A retrospective study was performed on 70 patients who underwent DECT-PA (15 PE present; 55 PE absent) scans. VMIs were reconstructed at different energy levels ranging from 35 to 200 keV using standard and strong levels with deep learning spectral reconstruction.

Background And Objective: Cerebral aneurysms occur as balloon-like outpouchings in an artery, which commonly develop at the weak curved regions and bifurcations. When aneurysms are detected, understanding the risk of rupture is of immense clinical value for better patient management. Towards this, Fluid-Structure Interaction (FSI) studies can improve our understanding of the mechanics behind aneurysm initiation, progression, and rupture.

Background: There is little information about when and how cavernosal sinusoidal endothelia develop in the external genitalia of fetuses.
Methods: We examined histological sections of erectile tissue in 37 human fetuses (25 males and 12 females) whose gestational age (GA) ranged from 8 to 40 weeks.
Results: The sinusoidal lumen was filled with blood in the glans of the penis and clitoris at a GA of 10-11 weeks, and in the corpus spongiosum at a GA of 15-16 weeks.
