ReviewImage-based monitoring of magnetic resonance-guided thermoablative therapies for liver tumors.
Minimally invasive treatment options for liver tumor therapy have been increasingly used during the last decade because their benefit has been proven for primary and inoperable secondary liver tumors. Among these, radiofrequency ablation has gained widespread consideration. Optimal image-guidance offers precise anatomical information, helps to position interventional devices, and allows for differentiation between already-treated and remaining tumor tissue. ⋯ Practical information concerning coils, sequence selection, and parameters, as well as sequence gating, is given. In addition, sources of artifacts are identified and techniques to decrease them are introduced, and the characteristic signs of residual tumor in T1-, T2-, and DWI are described. We hope to enable the reader to choose MR sequences that allow optimal therapy monitoring depending on the initial signal characteristics of the tumor as well as its size and location in the liver.

ReviewEndovascular renal artery denervation: why, when, and how?
Endovascular renal artery denervation (ERAD) is a new procedure to reduce renal and systemic sympathetic overactivity in hypertensive patients. The role of sympathetic overactivity is recognized since a long time as being one the contributor of human hypertension. ⋯ The purpose of this paper is to help interventionalists to better understand the medical and technical issues related to this new intervention. It is most likely that as underlined in a recent editorial several other technical approaches may appear in the future, however because this is the only technique that is available today, we will focus on radiofrequency based technique.

ReviewPatient safety in interventional radiology: a CIRSE IR checklist.
Interventional radiology (IR) is an invasive speciality with the potential for complications as with other invasive specialities. The World Health Organization (WHO) produced a surgical safety checklist to decrease the morbidity and mortality associated with surgery. ⋯ Use of the checklist will, we hope, reduce the incidence of complications after IR procedures. It has been modified from the WHO surgical safety checklist and the RAD PASS from Holland.

ReviewThe role of stent-grafts in the management of aortic trauma.
Stent graft has resulted in major advances in the treatment of trauma patients with blunt traumatic aortic injury (TAI) and has become the preferred method of treatment at many trauma centers. In this review, we provide an overview of the place of stent grafts for the management of this disease. ⋯ However, endovascular procedures in trauma require a sophisticated multidisciplinary and experienced team approach. More research and development of TAI-specific endograft devices is needed and large, multicenter studies will help to clarify the role of TEVAR compared with open repair of TAI.

ReviewPediatric vascular malformations: pathophysiology, diagnosis, and the role of interventional radiology.
The Mulliken and Glowacki classification (1982) differentiated vascular anomalies into two groups based on their endothelial characteristics: hemangiomas and vascular malformations. Vascular anomalies are localized defects of the vasculature that affect a limited number of vessels in a restricted area of the body. ⋯ Depending on the type of lesion, the location and degree of involvement and the clinical effect, different types of treatment would be required. For the purpose of this review, we concentrate solely on vascular malformations: the clinical features, genetics, diagnosis, and current treatment options.
