Given the increasing demand for interventional image-guided procedures, radiologists are increasingly sollicited by clinicians to participate in the management of patients prior to and after the interventional procedure, especially with regards to hemostasis. Therefore, radiologists should be familiar with the risk of procedure related hemorrhage. ⋯ Recommendations for preprocedure testing based on the type of procedure planned will be reviewed. Finally, limitations of hemostasis parameters will be discussed along with management of anticoagulants and antiplatelet agents before the procedure.

Fractures of the hip and pelvis are frequent and serious injuries in elderly patients. Due to the aging population, their incidence should double by 2050. ⋯ Delay in diagnosis increases the associated morbidity and mortality. The purpose is to review the imaging features of these fractures, the imaging techniques (projections, CT) to depict them and their classification based on severity.

Multiple chronic renal diseases evolve to end-stage kidney disease due to progressive renal tissue fibrosis at the level of the interstitium or glomeruli. Fibrosis often results from transformation of the extracellular matrix by cytokines and chemokines released by activated cells in the setting of recurrent episodes of acute inflammation. Newer techniques to image intrarenal inflammation and fibrosis are mandatory for the non-invasive evaluation of these processes to improve follow-up and monitoring of drug therapy. These techniques are based on methods of cellular and molecular imaging, and methods of functional, such as diffusion weighted imaging, and structural, such as elastography.

Presentation in several international conferences, at the stage of design and interim results of randomized trials regarding the appropriateness of percutaneous endovascular correction of renal artery stenosis has raised some questions among clinicians, including nephrologists. What lessons should get the interventional radiologist now published the first results?

Vomiting during the neonatal period is frequent. The purpose is to detect neonates and infants with digestive pathology requiring urgent management such as duodenal atresia, small bowel volvulus, acute intussusception, and hypertrophic pyloris stenosis. All of these conditions may be diagnosed by ultrasound which should be performed when clinically suspected.
