Our hospital from February 1993 to October by contrast enhanced CT 200 cases. There were 149 males and 51 females, the oldest was 68 years old and the youngest was 7 years old. The positive detection rate was significantly higher after enhanced scan. 1 Materials and Methods All 200 cases of the group using the United States GE9800 type CT machine, scanning time of 3 seconds, layer thickness, layer spacing of 10mm, window width: 80-150 brain, liver 150-250, window level is 40 ; Before the request of patients with fasting, liver and kidney function tests normal, negative iodine allergy test. The positive and negative contrasts of all the examined sites were as follows: skull, 51 cases, 27.5% negative, 37 positive, 72.5%; liver, 111 cases, negative 43 cases accounting for 38.7%, positive 68 cases, accounting for 61.3 %, Kidney, 38 cases, negative in 18 cases, accounting for 47.4%, positive in 20 cases, accounting for 52.6%.
