Imaging of Bone in the Head and Neck Region, is There More Than CT?

Abstract

Purpose of Review The objective of this review is to document the advances in non-ionising imaging alternatives to CT for the head and neck. Recent Findings The main alternative to CT for imaging bone of the head and neck region is MRI, particularly techniques which incorporate gradient echo imaging (Black Bone technique) and ultra-short or zero-echo time imaging. Since these techniques can provide high resolution isometric voxels, they can be used to provide multi-planar reformats and, following post processing, 3D reconstructed images of the craniofacial skeleton. As expected, the greatest advancements in recent years have been focused on enhanced image processing techniques and attempts to address the difficulties encountered at air-bone interfaces. Summary This article will review the imaging techniques and recent advancements which are bringing non-ionising alternatives to CT imaging of the bone of the head and neck region into the realm of routine clinical application.

Application of MRI and CT Images in Surgical Treatment of Early Cervical Cancer

“…Eley et al believed that low staging could lead to inadequate treatment, and postoperative radiotherapy and chemotherapy were often needed, resulting in a significant increase in total complications and seriously affecting the quality of life. Or the scope of the lesion was found to be beyond the expectation during the operation, resulting in increased difficulty of the operation or even having to give up the operation [5]. In addition, Masselli et al believed the clinical staging classification should be judged according to unified standards in patients with tumor staging, which could make the data of the world different medical institutions being comparable, so as to carry out data summary and analysis of therapeutic effect evaluation and the implementation of clinical trials.…”

Skull and scalp ultrasound in children: a review

“…Экспертным методом диагностики патологии костей и швов черепа является компьютерная томография (КТ). Однако в последние годы публикуется все больше работ о роли ионизирующего излучения в повышении риска развития онкологических заболеваний, особенно у детей раннего возраста [1][2][3][4]. Кроме этого, M. K. Yuan и соавт.…”

“…(2012) подчеркивается, что клиническая польза применения КТ несомненно должна превышать небольшой абсолютный риск, дозы облучения следует поддерживать на минимальном уровне, и при возможности желательно применять альтернативные методы, не связанные с ионизирующим излучением [2]. Перспективными альтернативами для визуализации костей и швов черепа являются ультрасонография (УС) и магнитно-резонансная томография (МРТ) [4].…”
