Abstract:
Objective To determine the diagnostic value of SPECT in lower digestive tract hemorrhage (LDTH). Methods Of the 24 LDTH cases,16 were tested by gastric mucosa imaging ,4 by 99m Tc PHA imaging,and the other 4 by 99m Tc RBC imaging.All the patients' diagnosis were confirmed by surgery and pathology. Results The sensitivity and the specificity of the gastric mucosa imaging were 100%(16/16) and 93.7%(15/16),respectively. The sensitivity of the 99m Tc PHA imaging and the 99m Tc RBC imaging was 75.0%(3/4) and 75.0 %(3/4), respectively, but had no specificity. Conclusions SPECT has very high sensitivity and specificity in the diagnosis of Meckel's diverticulum. 99m Tc PHA imaging and 99m Tc RBC imaging may help to determine the position of bleeding in unkown causes of LDTH.
