Image-guided ablations are nowadays applied in the treatment of a wide group of diseases and in different organs and regions, and every day interventional radiologists have to face more difficult and unusual cases of tumour ablation. In the present case review, we report four difficult and unusual cases, reporting some tips and tricks for a successful image-guided treatment.

Background LGE-MRI is widely used to assess cardiac RF ablation lesions. However, LGE-MRI requires contrast injection and the appearance, dimensions and visibility of lesions in LGE-MRI noticeably change with time after ablation and time after contrast injection. Recently proposed non-contrast T1-weighted (T1w) technique is only applicable to visualize acute (< 3 days) RF lesions. The main goal...

In recent years, the effectiveness of anti-TNF therapy in treating rheumatoid arthritis (RA) has become apparent. While trials of IL-1 receptor antagonist in RA have been encouraging, it clearly is more difficult to target two molecules (IL-1 alpha and beta) than one (TNF-alpha). In his review article, Professor Wim van den Berg argues that both TNF-alpha and IL-1 must be blocked in RA and that...

Deer antler is a unique example of mammalian long bone because it regenerates annually with an extremely rapid rate of growth. This study describes a low-field NMR technique combined with cryoporimetric calibration for the estimation of pore size distribution in antler bone from spin-spin (T2) relaxation data. Pore sizes determined by the NMR method have been compared with the more traditional ...

Organic coatings have been widely used in atomic physics during the last 50 years because of their mechanical properties, allowing preservation of atomic spins after collisions. Nevertheless, this did not produce detailed insight into the characteristics of the coatings and their dynamical interaction with atomic vapors. This has changed since the 1990s, when their adsorption and desorption pro...

We propose a novel doping method of graphene using the cyclic trap-doping method with low energy chlorine adsorption. Low energy chlorine adsorption for graphene chlorination avoided defect (D-band) formation during the doping by maintaining the π-bonding of the graphene, which affects conductivity. In addition, by trapping chlorine dopants between the graphene layers, the sheet resistance coul...

This paper presents structural, morphological and preliminary ultrasonic characterizations of the β-Cyclodextrin/hydroxyapatite (CD-HAp) composites synthesized by an adapted co-precipitation method. The structural and morphological properties were evaluated by Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDX). The specific surface area, pore size and pore volume ...
