Methods Three methods to inject 99 mTc-MAA through veins in the dorsum of foot were introduced: one-time injection of the full dosage,slow injection at an equal speed and injection at three times.

Recently, growing interest has been put in labeling folate and its derivatives with medical radioisotopes, such as ()~(99m)Tc, ()~(111)In, in order to diagnosing or imaging malignant tumor.

AIM: To study the methods and the conditions of(labeling) the 2 kinds of single chain antibodies(hdsFv,scFv-PE38) of anti-hepatocellular carcinoma with ~(99m)Tc.

Radioisotope ~(99m)Tc is widely applied in clinical diagnosis.

Methods HBF, HAF and PVF were determined in 20 patients with primary liver cancer and 10 normal individuals by detecting colloid re-uptake by liver cells and the method of slope in the first pass after injecting 99m Tc-phytate.

The parameters reflecting the function of thyroid were calculated,including rectified ratio(RR),uptake ratio(UR) and 99m Tc percentage uptake(PU).

To study the prevalence of DVT in patients with pulmonary embolism(PE),~(99)Tc~m-MAA lower extremity vein scan is performed in 71 PE patients.

circulating antibodies against MAA adducts were evaluated in 40 patients with alcohol-induced liver disease(ALD),in 40 patients with non alcohol-induced liver disease(NALD),in 30 heavy drinkers(HD)without liver damage and in 40 healthy controls by enzyme-linked immunosorbent assays(ELISA).
