Liver scintigraphy and ultrasonography for the diagnosis of focal and diffuse diseases

The scinti-photos and ultra-sono-photos of 186 patients with focal and diffuse diseases of liver were collected and analysed. All the data were get from the in-patients of China-Japan Friendship Hospital. The Sigma 438 typed γ camera (USA) was used. Fifteen min after 99mTc-phytate were injected i.v.. If any defect region was found, it was recorded as a SOL; the SSA 90 A, SAL 77 A and SAL 50 A US scanners (Japan) were used, if any abnormal echo pattern was found, it was a SOL. Of scanners (Japan) were used, if any abnormal echo pattern was found, it was a SOL. Of 134 patients have done both examinations during 7 days, 122 patients had coincident results occupied 91.0%. For detection of SOL, the sensitivity of scintigraphy is 94.1%, specificity is 94.2%, accuracy is 94.8%; the sensitivity of US is 100%, specificity is 89.7%, the accuracy is 95.6%. The hepatic blood flow and blood pool study showed that 104 from 115 patients were coincident (90.4%). The spleen and liver accumulation ratio determination showed that 51 from 64 subjects were coincident (80.0%). The characteristic features of scintigraphy and US graphs were described in hepatoma, hemangioma, cyst abscess and cirrhosis. The advantages of these examinations were discussed and concluded that their procedures are valuable and widely available
