“…Vascular malformations can be located extra or intraosseous, causing changes in the shape and density of the bone 13 . In the present case, there was a change in the vestibular contour of the maxillary ridge, confirmed by a cone beam computed tomography exam, in addition to mobility of the incisor teeth.…”

Background and AimThe approach to vascular malformations in the face is a challenging step for professionals involved in the treatment of these anomalies. The objective is to describe a rare case of extensive vascular malformation in the face in an adult patient who had previously undergone several unsuccessful treatments during childhood and adolescence.Materials and MethodsA 46‐year‐old female patient reported an aesthetic discomfort in her face due to an increase in the volume of the upper lip and recurrent spontaneous bleeding in the oral cavity. On oral clinical evaluation, a blue‐purple colour, firm consistency on palpation, extension into the oral cavity, and moderate mobility of the incisors in the right hemimaxilla were observed. Angiography, magnetic resonance imaging and cone beam computed tomography were performed to verify the lesion's anatomical limits and hemodynamic properties. Four injections of sclerotherapy with an injection of 5% monoethanolamine oleate foam were performed.ResultsA significant reduction in the extent of vascular malformation was noted. At the moment, the patient had 3 years of follow‐up. She is extremely satisfied with the aesthetic result, and has had no episode of spontaneous bleeding or other complications.ConclusionsThe request for new imaging exams allowed the characterization and precise delimitation of the vascular malformation, guiding the use of a minimally invasive technique using the injection of monoethanolamine oleate foam, providing an effective and satisfactory result for the patient.

“…Dental and maxillofacial cone-beam CT procedures should not exceed the dose of comparable CT procedures for high-contrast objects (typical CTDI vol < 10 mGy). (232) When used to guide biopsies, cone-beam CT can reduce patient dose and improve targeting accuracy compared with conventional CT (Abi-Jaoudeh et al., 2016). Cone-beam CT is also becoming increasingly important during interventional fluoroscopy procedures (Wallace et al., 2008; Lightfoot et al., 2013; Corredoira et al., 2015). It can provide information and guidance that is not otherwise available during the procedure, and can increase the safety of the procedure (Lee et al., 2014).…”

The International Commission on Radiological Protection (ICRP) first introduced the term ‘diagnostic reference level’ (DRL) in 1996 in Publication 73. The concept was subsequently developed further, and practical guidance was provided in 2001. The DRL has been proven to be an effective tool that aids in optimisation of protection in the medical exposure of patients for diagnostic and interventional procedures. However, with time, it has become evident that additional advice is needed. There are issues related to definitions of the terms used in previous guidance, determination of the values for DRLs, the appropriate interval for re-evaluating and updating these values, appropriate use of DRLs in clinical practice, methods for practical application of DRLs, and application of the DRL concept to newer imaging technologies. This publication is intended as a further source of information and guidance on these issues. Some terminology has been clarified. In addition, this publication recommends quantities for use as DRLs for various imaging modalities, and provides information on the use of DRLs for interventional procedures and in paediatric imaging. It suggests modifications in the conduct of DRL surveys that take advantage of automated reporting of radiation-dose-related quantities, and highlights the importance of including information on DRLs in training programmes for healthcare workers. The target audience for this publication is national, regional, and local authorities; professional societies; and facilities that use ionising radiation for medical purposes, and responsible staff within these facilities. A full set of the Commission’s recommendations is provided.

“…4 Three-dimensional rotational angiography and cone-beam computed tomography (CT) imaging capabilities are available in most advanced angiographic imaging systems equipped with recent flat-panel detector technology. [7][8][9][10] This novel intraoperative cone-beam CT imaging technique involves projection x-ray imaging with rotation of C-arm around the patient for ∼200 degrees and reconstruction of a 3D CT-like cross-sectional dataset of vasculature and soft-tissue structures. In addition to vascular imaging with contrast injection, this technology can be used for imaging various interventional devices such as inferior vena cava filters and stents, and with appropriate software guidance, can enable safe percutaneous needle procedures in the interventional suite.…”
