ReviewSystematic review of minimally invasive ablation treatment for locally advanced pancreatic cancer.
Unresectable locally advanced pancreatic cancer with or without metastatic disease is associated with a very poor prognosis. Ablation techniques are based on direct application of chemical, thermal, or electrical energy to a tumor, which leads to cellular necrosis. ⋯ Inoperable cases of pancreatic cancer have been treated by various ablation techniques in the last few years with promising results. The purpose of this review is to present the current status of local ablative therapies in the treatment of pancreatic advanced tumor.

ReviewVascular 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.

ReviewUltrasound-guided interventional procedures around the shoulder.
The aim of this review is to illustrate the spectrum of ultrasound-guided procedures around the shoulder. The shoulder is affected by a wide range of both, traumatic and degenerative diseases. Ultrasound guidance is a low-cost and safe tool to perform minimally invasive interventional procedures around the shoulder. ⋯ In adhesive capsulitis, different therapeutic ultrasound-guided techniques such as corticosteroid injection, capsular distension (sodium chlorate solution; sodium chlorate and corticosteroids; air) and viscosupplementation are evaluated. Acromion-clavear injection of steroid and lidocaine solution under ultrasound guidance is easy to perform and is indicated in conservative treatment of painful osteoarthrosis. The treatment of rotator cuff tendinosis and partial tears with ultrasound-guided injection of concentrated autologous platelets is also described.

ReviewCT-MR integrated diagnostic imaging of the oral cavity: neoplastic disease.
The oral cavity is a complex anatomical region consisting of different anatomical sites and subsites. Cancer undoubtedly represents the most frequent and relevant disease of this region. ⋯ Cross-sectional computed tomography (CT) and magnetic resonance imaging (MRI) play a key role in staging locoregional disease by demonstrating submucosal spread and involvement of deep layers; evaluation of specific pathways of spread to peculiar anatomical subsites is also fundamental information that can be obtained with these techniques. The purpose of this paper is to illustrate CT and MRI findings of anatomical subsites involved by tumours of the oral cavity.

ReviewClinical application of lung ultrasound in patients with acute dyspnea: differential diagnosis between cardiogenic and pulmonary causes.
This review discusses the usefulness of bedside lung ultrasound in the diagnostic distinction between the various causes of acute dyspnoea in the emergency department, with special attention to the differential diagnosis of pulmonary oedema and exacerbation of chronic obstructive pulmonary disease (COPD). This is made possible by using mid- to low-end scanners and simple acquisition techniques accessible to both radiologists and clinicians. Major advantages include ready availability at the bedside, the absence of ionising radiation, high reproducibility and cost efficiency. ⋯ These artefacts are caused by the interaction of water-rich structures and air, called comet tails or B-lines. When such artefacts are widely detected on anterolateral transthoracic lung scans, diffuse alveolar-interstitial syndrome can be diagnosed, which is often a sign of acute pulmonary oedema. This condition rules out exacerbation of COPD as the main cause of acute dyspnoea.
