报告简介

Ultrasound has been used for medical diagnosis and therapy for more than 5 decades. It has been proven to be non-invasive and to have many clinical applications in diagnosing a variety of diseases including cardiac problems and tumors. The current trends are in developing approaches for assessing elastic properties of tissues to circumvent the problem that has plagued medical imaging for years in that sometimes lesions such as tumors are palpable but not visible on images and in developing high frequency (>20 MHz) devices to visualize superficial anatomical structures and to image smaller objects including small animals and neonates.

More exciting developments of medical ultrasound recently however are in the therapeutic fronts. These include high intensity focused ultrasound (HIFU) treatment of uterine fibroids, essential tremor, and other brain diseases under imaging guidance which can be MR or ultrasound. Ultrasound enhanced drug delivery across the blood brain barrier (BBB) in conjunction with the introduction of gas containing contrast agents has garnered intense interest for treating brain tumors. The last but not the least is in cosmetic ultrasound which has become immensely popular in lifting and tightening skin.  

超声在医学诊断和治疗的应用已有50多年可以在临床上非侵入地诊断心脏问题和肿瘤等多种疾病。例如有些肿瘤虽然很明显但成像技术缺无法检测到目前的发展趋势是评估组织的弹性性能以克服这个问题如发展频率高于20MHz的超声仪器来观察小动物或新生儿的皮肤浅层解剖结构。

然而更令人兴奋的是近些年医学超声在治疗方面应用包括高强度聚焦超声(HIFU)治疗子宫肌瘤、原发性震颤、以及基于MR或超声的脑疾病术中导航。超声对血脑屏障(BBB)的药物输送具有增强作用因此被用于脑肿瘤的治疗。另外如今超声也已成为一种非常流行的舒缓和绷紧皮肤的保养方式。
