Summary:PROBLEM TO BE SOLVED: To provide a radiation shield that is used in biopsy of a sentinel lymph node, reduces influence due to artifacts and halation using a simple method, regardless of the size of the tumor or the timing of imaging, and images the sentinel lymph node directly near a lymph tube and a tumor that is drawn immediately after starting a sentinel lymph node scintigraphy. SOLUTION: The radiation shield made of a radiation-shielding material comprises a flat central shield section, and an outer periphery screen section, that is provided in the direction of the outer periphery from the central shield section. The outer periphery shield section gradually decreases the shielding capacity, starting from the central side to the outer periphery side. COPYRIGHT: (C)2003,JPO
