Reproductive Age Women

Uterine leiomyomas (fibroids) affect 20–40% of reproductive age women and are the major indication for hysterectomy. Magnetic Resonance-guided Focused Ultrasound Surgery (MRgFUS) is a new, potentially disruptive, non-invasive and uterine-sparing treatment option that has been shown to yield similar or better clinical outcomes than other uterine-sparing interventions. However, the costs of MRgFUS and other minimally-invasive treatment options have not been studied using US practice data. This study attempts to fill this void. And since uterine fibroids are the first FDA-approved indication for MRgFUS treatment, this study may also have implications for other indications which are now investigational.

Recent Developments

: Ultrasound has been broadly used in biomedicine for both tumor diagnosis as well as therapy. The applications of recent developments in micro/nanotechnology promote the development of ultrasound-based biomedicine, especially in the field of ultrasound-based drug delivery and tumor therapy. Ultrasound can activate nano-sized drug delivery systems by different mechanisms for ultrasound-triggered on-demand drug release targeted only at the tumor. Ultrasound targeted microbubble destruction (UTMD) technology can not only increase the permeability of vasculature and cell membrane via sonoporation effect but also achieve in situ conversion of microbubbles into nanoparticles to promote cellular uptake and therapeutic efficacy. Furthermore, high intensity focused ultrasound (HIFU), or sonodynamic therapy (SDT), is considered to be one of the most promising and representative non-invasive treatment for cancer. However, their application in the treatment process is still limited due to their critical treatment efficiency issues. Fortunately, recently developed micro/nanotechnology offer an opportunity to solve these problems, thus improving the therapeutic effect of cancer. This review summarizes and discusses the recent developments in the design of micro- and nano- materials for ultrasound-based biomedicine applications.

The concept of brain lesioning is well established in adult tremor and early results from MRgFUS trials have shown great efficiacy. In addition, work has been done to show that is possible to target and ablate tumors with transcranial systems. However, there is little to no work performed on neonatal and pediatric patients. Based on clinical presentation of IVH and epilepsy, there is a clear clinical need for non-invasive treatments as current treatment techniques have complications (eg. secondary intracerebral hemorrhages from tPA). With our initial data, neonatal and pediatric patients possess unique skull and brain properties that facilitate and simplify the transmission of focused ultrasound. The open fontanelle and thinner skulls potentially reduce the need for lower frequencies which opens up the possibility of using existing MRgFUS transducers to perform the treatment and reduce the upfront investments. Our project will characterize the acoustic properties of pediatric skulls over 3 frequencies, develop a refocusing algorithm based on the acoustic data, simulate the acoustic transmission through the skull to study the effects on the target and surrounding areas and validate the algorithm on a porcine model.

The ExAblate Neuro allows for the non-invasive treatment of a wide variety of neurological problems, however is subject to smearing of its focal spot when the transducer arrays come in contact with the skull. Partnering with the Focused Ultrasound Foundation, this project had the ultimate goal of designing and testing a new model that allows for better prediction of phase shift for each individual array within the ExAblate Neuro when compared to the current model. This report explores the data exploration steps taken to obtain preliminary findings as well as details the conclusions reached in phase 1 of this project.
