    Needle Tip Visibility in 3D Ultrasound Images.
    Cardiovasc Intervent Radiol 2017 Sep 19. Epub 2017 Sep 19.
    Department of Medical Informatics, Erasmus MC, University Medical Center Rotterdam, Wytemaweg 80, Room Na 2506 Erasmus MC, 3015 CN, Rotterdam, The Netherlands.

    Purpose: To evaluate whether a new electrode embedded with an electromagnetic position sensor (EMPS) improves the technical feasibility of percutaneous radiofrequency ablation (RFA) in patients with hepatic tumors difficult to place an electrode under ultrasonography (US) guidance and to assess short-term therapeutic efficacy and safety.

    Materials And Methods: This prospective study was approved by the institutional review board, and written informed consent was obtained from all patients. Between January 2015 and December 2016, 10 patients (7 men and 3 women; age range 52-75 years) with a single hepatic tumor (median 1. Read More
