Description

Using scintiphotosplenoportography which permits a clear visualization of portal circulation by injecting 99mTcO4- into the spleen, quantitative studies on portal circulation were performed. Thirty five patients with various disorders were studied. The scintillation camera employed was a Picker Dynacamera system. The velocity of portal flow was calculated by estimating the time for 99mTcO4- to travel a known distance between the two areas of interest over the splenic vein. The spleen to liver time was calculated by subtracting the peak activity time over the spleen from that over the liver. The velocity of portal flow and the spleen to liver time were 9.78cm/sec, 2.67sec in patients without liver disease, 7.80 cm/sec, 3.45sec in patients with chronic hepatitis, and 4.39cm/sec, 4.72sec in cirrhosis respectively. Consequently, in patients with cirrhosis the velocity of portal flow was reduced and the spleen to liver time was prolonged significantly.
