Characterization of Hepatobiliary Scintigraphy using Linear Equations

Hepatobiliary radionuclide imaging is typically performed to assess the acute or chronic cholecystitis. Occasionally, initial 1 h imaging reveals an obstructive pattern of radiopharmaceutical distribution with non-visualization of the hepatic or extra-hepatic (EH) bile ducts, gallbladder and small intestinal activity. One hundred and thirty five infants under 12 months of age (65 females and 70 males) with were studied at Nuclear Medicine department in Royal care center of Khartoum Hospital during the years 2012-2015, 99mTc HIDA scan was administered intravenously, and images were obtained for up to 24 hours or until gastrointestinal excretion was noted. The result of this study showed that there is linear relationship between counts at 5 minute up to 60 using 5 minute interval, which start at 1.2 counts/minute up to 1.5 counts at 60 minute. In conclusion we noted that a strong direct relationship between these time were the strength of these relation decreased with increasing the time interval.
