ReviewInterventional radiology techniques for pain reduction and mobility improvement in patients with knee osteoarthritis.
Osteoarthritis of the knee is the most common cause of chronic knee pain being more prevalent in middle-aged and elderly patients. Symptomatic patients complain of pain and mobility impairment. ⋯ These therapies aim to control pain and inflammation, improve mobility and function whilst the novel cell-based therapies have the potential for bone and cartilage regenerative repair facilitating the delay to surgery. The purpose of this review is to illustrate the technical aspects, the indications and the methodology of local therapies for knee osteoarthritis performed by interventional radiologists and provide current evidence.

ReviewArtificial intelligence and medical imaging 2018: French Radiology Community white paper.
The rapid development of information technology and data processing capabilities has led to the creation of new tools known as artificial intelligence (AI). Medical applications of AI are emerging, and the French radiology community felt it was therefore timely to issue a position paper on AI as part of its role as a leader in the development of digital projects. ⋯ In addition to the principles set forth at the Asilomar Conference on Beneficial AI, the French radiology community has developed ten principles aimed at governing the use and development of AI tools in a manner that will create a concerted approach centered on benefits to patients, while also ensuring good integration within clinical workflows. High-quality care in radiology and opportunities for managing large datasets are two avenues relevant to the development of a precision, personalized, and participative radiology practice characterized by improved predictive and preventive capabilities.

ReviewAcute mesenteric ischemia: A critical role for the radiologist.
Acute mesenteric ischemia is defined as an inadequate blood supply to the gastrointestinal tract resulting in ischemic and inflammatory injury that may progress to necrosis of the bowel wall. Prognosis is poor with a mortality rate greater than 95% without treatment, dropping to around 70% when surgical treatment is performed. Contrast-enhanced computed tomography (CT) has become the cornerstone of the diagnosis by showing features of vascular disorders (occlusion and/or insufficient blood supply) and features of intestinal ischemic injury. ⋯ The treatment involves multidisciplinary management by gastroenterologists, vascular and digestive surgeons, cardiologists, intensivists, and diagnostic and interventional radiologists. Based on our experience at a dedicated mesenteric stroke center, this article gives an overview of the diagnosis of acute mesenteric ischemia. The goal of this review is to improve the understanding of the imaging-based diagnosis to further improve the management of this life-threatening condition.

ReviewAugmented osteoplasty for proximal femur consolidation in cancer patients: Biomechanical considerations and techniques.
According to the literature, prophylactic consolidation of lytic metastasis located in the proximal femur is recommended when the Mirels' score is above 8. Osteoplasty alone provides inadequate consolidation but various devices have been used in association for better consolidation. ⋯ A Pubmed research found 5 studies that evaluated augmented osteoplasty of the proximal femur in cancer patients. All devices demonstrate adequate safety and low rate of secondary pathological fractures.

Lung cancer screening by low-dose computed tomography (CT) has been proven to reduce lung cancer-related mortality by 20%, in the National Lung cancer Screening Trial (NLST). Low-dose CT acquisition protocols should result in effective dose not exceeding 1.5mSv, and should be read by radiologists who have an expertise in the field. ⋯ The major harm of screening is overdiagnosis, which correspond to the detection of indolent tumours that would not cause the subject death. Ongoing research for the development of useful biomarkers to be combined to imaging could improve the accuracy of lung cancer screening.
