ABSTRACT: Discography test associated with the scanner (discoscanner) is an exam that has been a renewed interest in recent few years. Thanks to the emergence of new interventions such as disc prosthesis, the procedures require confirmation of the disc level to deal with and the origin of discogenic symptoms. The aim of this paper is to describe the techniques, challenges and tips as well as the interpretation of functional and morphological examination.

ABSTRACT: Transfacet screws may be useful for stabilizing segments reconstructed with bone graft or cages, the role of supplementary posterior fixation, particularly minimally invasive techniques such as transfacetar percutaneous screws is relevant. To benefit from a mechanical fixation after anterior arthrodesis without the inconveniences of the open classical posterior surgical intervention, we have developed a new procedure performed under local anesthesia and CT guidance and based on the intra-articular application of screws. This study was designed to demonstrate the feasibility of using a CT-scan to perform posterior arthrodesis of the spine under local anesthesia.

ABSTRACT: Splenic artery aneurysms are now diagnosed more frequently thanks to the increase and improvement in different imaging techniques. In case of rupture they are potentially life threatening and thus in certain cases may require appropriate preventive treatment. This treatment should be offered to patients with suspected pseudoaneurysms, with an aneurysm larger than 20mm in diameter, or which is progressing. The development of interventional endovascular radiology has provided new therapeutic options for the management of aneurysms, by excluding the sac from the arterial circulation with coil embolisation or with a covered stent. The success rate of these treatments is between 75 and 100% with significantly less morbidity and mortality than with surgical techniques.

ABSTRACT: To determine the usefulness of two classification systems for pelvic prolapse on MRI.
Prospective study of 30 patients with symptoms of pelvic prolapse performed in a single center. All patients underwent clinical evaluation followed by dynamic pelvic MRI within 15 days. All MR examinations were reviewed by three readers using both classification systems based on different anatomical landmarks. The first used the pubococcygeal line and the second used the midpubic line.
For prolapse detection, the correlation between clinical examination and MRI was good to very good, ranging between 74 and 89%. For prolapse staging, the correlation was poor to moderate. Inter-observer agreement was good to very good (kappa between 0.67 and 0.95). It was slightly better at the mid stage, with both systems (kappa between 0.83 and 0.97). Comparison of the inter-observer agreement between both MRI classification systems showed better results for the system using the pubococcygeal line (p<0.005).
The classification system based on the pubococcygeal line appeared more reliable and simple for th eevaluation of pelvic prolapse on MRI.
