The purpose of this study is to suggest a quantitative supplementary index for patients with suspected Raynaud phenomenon. The subjects were 99 patients with suspected Raynaud phenomenon, 48 patients with low likelihood, 16 patients with middle range and 35 patients with high range. The test was instilled in ice water at 15.2 ±0.8°C for 10 minutes of both hands and then venous injected of 99m-Tc 370 Mbq(10 mCi). After 5, 10 and 20 minutes, temperature changes of both fingers were measured. As a result, the temperature of the fingers was 32.6±4.9°C in patients with a low diagnostic probability of Raynaud syndromes and 22.7±6.0°C for those with a high diagnostic probability(p<0.05). In conclusion, we could confirm the difference of Raynaud phenomenon and finger temperature, and confirmed the possibility of secondary diagnosis as a quantitative index of Raynaud’s diagnosis.
