A fiducial implant for use in the body of a living being to enable the localization, e.g., radiographic, of targeted internal tissue. The implant is in the form of an elongated, e.g., rod-like, central section and a pair of end sections, each of said end sections is arranged so that it can be readily imaged by a first type of imaging, e.g, X-ray imaging, ultrasonic imaging and magnetic resonance imaging. The implant can be inserted via a needle or cannula into targeted tissue so that when exposed to the first type of imaging the bulbous ends of the implant can be readily discerned. Once the bulbous ends are localized a therapy beam of radiation can be precisely directed to the targeted tissue
