OBJECTIVE To determine whether uterine artery embolization is safe and effective for treating uterine leiomyomata. METHODS We analyzed 200 consecutive patients (61 reported previously) undergoing uterine artery embolization for the treatment of uterine leiomyomata at a single institution. After treatment, follow-up data were obtained by written(More)
Navigation systems, devices, and intraprocedural software are changing the way interventional oncology is practiced. Before the development of precision navigation tools integrated with imaging systems, thermal ablation of hard-to-image lesions was highly dependent on operator experience, spatial skills, and estimation of positron emission tomography-avid(More)
PURPOSE To determine whether baseline variables are associated with treatment success after uterine artery embolization for treatment of uterine leiomyoma. MATERIALS AND METHODS Two hundred consecutive patients who underwent uterine artery embolization at one institution were prospectively examined. Baseline clinical variables measured included age, race,(More)
This article reviews the published efforts to characterize hepatic motion secondary to respiration, with the specific goal of defining the limitations and potential applications of image-guided systems in percutaneous liver interventions (computer assisted interventions). Hepatic motion and deformation due to respiration remain obstacles to applying(More)
Personalized therapies play an increasingly critical role in cancer care: Image guidance with multimodality image fusion facilitates the targeting of specific tissue for tissue characterization and plays a role in drug discovery and optimization of tailored therapies. Positron-emission tomography (PET), magnetic resonance imaging (MRI), and(More)
Radiofrequency ablation of primary and metastatic liver tumors is becoming a potential alternative to surgical resection. We propose a novel system that uses real-time electromagnetic position sensing of the needle tip to help with precision guidance into a liver tumor. The purpose of this study was to evaluate this technology in phantom and animal models.(More)
PURPOSE To evaluate the influence of pulsed fluoroscopy (PF), nonpulsed fluoroscopy (NPF), and various fluoroscopic techniques on the absorbed ovarian dose (AOD) associated with uterine artery embolization (UAE) of leiomyomata. MATERIAL AND METHODS Ovarian location was estimated from preprocedural pelvic magnetic resonance images of 23 patients previously(More)
BACKGROUND Recent developments in radiotherapeutic technology have resulted in a new approach to treating patients with localized lung cancer. We report preliminary clinical outcomes using stereotactic radiosurgery with real-time tumor motion tracking to treat small peripheral lung tumors. METHODS Eligible patients were treated over a 24-month period and(More)
PURPOSE To determine whether the severity of postprocedure pain associated with uterine artery embolization (UAE) for leiomyomata can be predicted and if its severity can predict outcome. MATERIALS AND METHODS Eighty-one patients underwent UAE and had postprocedure pain managed with use of patient-controlled analgesia (PCA) in the form of an intravenous(More)
PURPOSE To evaluate the effectiveness of intraarterial lidocaine in controlling pain after uterine artery embolization (UAE). MATERIALS AND METHODS In this double-blind prospective study, patients undergoing UAE received preservative-free 1% lidocaine or saline solution (control) in the uterine arteries before embolization. Postprocedural pain was managed(More)
