Prominence eruptions are thought to be an integral part of coronal mass ejections. However, recent statistical studies obtained conflicting conclusions regarding this relationship: a nearly one-to-one correspondence to a poor association. We revisited this problem using all the eruptive prominences detected automatically from the daily images obtained by the Nobeyama Radioheliograph. The images were made with a 10 min cadence so only slower eruptions could be detected from these images. During January 1996 to December 2001, there were 226 prominence eruptions detected this way and 182 of them had white light observations from the Solar and Heliospheric Observatory (SOHO) mission. When we compared the radio and white light data, we found that 76 CMEs, while only 16 remaining 8 suggesting partial eruption. We conclude that there is good association between CMEs when the prominence eruptions have a radial component of the velocity is dominant.
