RESUMO
This article reviews the emerging roles of functional imaging in the assessment of peritoneal carcinomatosis in ovarian cancer, focusing on the use of diffusion-weighted magnetic resonance imaging (DW-MRI) and 2-[18F]-fluoro-2-deoxy-d-glucose positron-emission tomography combined with computed tomography (PET-CT), their advantages and shortcomings as well as the added-value over conventional imaging.

Contrast induced nephropathy (CIN) is traditionally associated with outpatient imaging studies. More recently, patients afflicted with vascular pathologies are increasingly undergoing endovascular treatments that require the use of iodinated contrast media (CM) agents, thus placing them as risk of developing CIN. As perioperative physicians, anaesthetists should be aware of the risk factors and measures that might minimize acute kidney injury caused by CM. This review evaluates recent data regarding preventive measures against CIN and where possible, places the evidence in the context of the patient receiving endovascular surgical treatment. Measures including the use of peri-procedural hydration, N-acetylcysteine, statins, remote ischaemic preconditioning, renal vasodilators and renal replacement therapy and the use of alternatives to iodinated contrast agents are discussed. It should be noted that most of the available data regarding CIN are from non-surgical patients.

Four cases of isolated popliteus tendon avulsion in skeletally immature patients that presented to our institution over an 11 month period are reviewed. All the cases had characteristic features on the initial knee radiograph and the diagnosis was confirmed using magnetic resonance imaging (MRI). A brief literature review is included. The aim of the present study was to raise awareness of the radiographic findings of isolated popliteus tendon avulsion in adolescent patients.
