Microwave ablation of renal tumors: state of the art and development trends.

In the last decades an increased incidence of new renal tumor cases has been for clinically localized, small tumors <2.0 cm. This trend for small, low-stage tumors is the reflection of earlier diagnosis primarily as a result of the widespread and increasing use of non-invasive abdominal imaging modalities such as ultrasound, computerized tomography, and magnetic resonance imaging.

Vascular and interventional radiology radiofrequency ablation of benign thyroid nodules and recurrent thyroid cancers: literature review.

Thermal radiofrequency ablation is a relatively new, minimally invasive modality employed as an alternative to surgery in patients with benign thyroid nodules and recurrent thyroid cancers. Different recommendations are necessary for the optimal use of radiofrequency ablation for thyroid nodules. These recommendations are based on a comprehensive analysis of the current literature, the results of multicenter studies, and expert consensus.

The role of MDCT arthrography in the follow-up of scapholunate stabilisation.

Purpose: The aim of this study was to assess outcomes in a group of patients with scapholunate dissociation treated with stabilisation surgery (Brunelli-Stanley) and to compare arthrography with multidetector computed tomography (MDCT) with conventional radiography, the gold standard in the follow-up of wrist surgery.

Materials And Methods: Twelve patients (13 wrists) underwent surgery for scapholunate dissociation and were followed up with clinical (visual analogue scale, Mayo Wrist Score, Patient-Rated Wrist Evaluation, and Disabilities of the Arm, Shoulder, and Hand) and radiological assessment (conventional radiography and CT arthrography). Conventional radiography was assessed for: the scapholunate gap, scapholunate angle, radiolunate angle, capitate-lunate angle, and carpal height index; the CT arthrography images were also evaluated for: the distance between the dorsal exit hole of the bone tunnel and the proximal scaphoid pole, the thickness and tension of the flexor carpi radialis (FCR) strip, and any signs of joint degeneration.

Cosmetic treatments: an emerging field of interest for interventional radiologists.

The current trend in medical care in the 21st century is evolving into a minimally invasive specialty. The interest of Interventional Radiology (IR) in cosmetic is increasing particularly for outsetting patients, in the treatment of soft tissue vascular malformations, us-guided injections of Botox and varicous veins management. Advantages of cosmetic IR treatments are many: treatments takes less than an hour and provides immediate relief of symptoms; no scaring, because the procedure does not require a surgical incision; an immediate return to normal activity with little or no pain; and high success rate and low recurrence rate compared to surgery.
