Prediction of Obliteration After the Gamma Knife Radiosurgery of Arteriovenous Malformations Using Hand-Crafted Radiomics and Deep-Learning Methods.

Introduction: Brain arteriovenous malformations (bAVMs) are vascular abnormalities that can be treated with embolization or radiotherapy to prevent the risk of future rupture. In this study, we use hand-crafted radiomics and deep learning techniques to predict favorable vs. unfavorable outcomes following Gamma Knife radiosurgery (GKRS) of bAVMs and compare their prediction performances.

A systematic review of diagnostic and interventional techniques in non-occlusive hepatic artery hypoperfusion syndrome.

Objective: This systematic review aims to elucidate the diagnostic capabilities of imaging techniques in identifying Non-Occlusive Hepatic Artery Hypoperfusion Syndrome (NOHAH) and to evaluate the efficacy and outcomes of splenic artery embolization (SAE), including the choice and placement of embolic agents.

Materials And Methods: A comprehensive literature search was conducted using PubMed, CINAHL, and Scopus databases, adhering to PRISMA guidelines. Fifteen studies encompassing 240 patients treated with embolization (using coils or Amplatzer Vascular Plugs (AVP)) were analyzed.

Double-salt formation in crystal structures containing [Co(en)]Cl.

The structures of three racemic double salts of [Co(en)]Cl (en is ethane-1,2-diamine, CHN), namely, bis[tris(ethane-1,2-diamine-κN,N')cobalt(III)] hexaaquasodium(I) heptachloride, [Co(en)][Na(HO)]Cl, bis[tris(ethane-1,2-diamine-κN,N')cobalt(III)] hexaaquapotassium(I) heptachloride, [Co(en)][K(HO)]Cl, and ammonium bis[tris(ethane-1,2-diamine-κN,N')cobalt(III)] heptachloride hexahydrate, (NH)[Co(en)]Cl·6HO, have been determined, and the structural similarities with the parent compound, tris(ethane-1,2-diamine-κN,N')cobalt(III) trichloride tetrahydrate, [Co(en)]Cl·4HO, are highlighted. All four compounds crystallize in the trigonal space group P-3c1. When compared with the parent compound, the double salts show a modest increase in the unit-cell volume.

Structure of Λ(δλλ)-[Co(en)]I(I).

The structure of tris-(ethane-1,2-di-amine-κ ')cobalt(III) bis-(iodide) triiodide, [Co(CHN)]I(I), at 120 K has ortho-rhom-bic (222) symmetry. The di-amine nitro-gen atoms form N-H⋯I hydrogen bonds throughout the lattice, resulting in a three-dimensional network, which involves the iodide and all atoms in the triiodide anions.
