Relation of syndrome differentiation and the typing and graduation of CT scanning results（Cases）"

Figure 1

Focal type fatty liver A: The fatty infiltration of the liver was local; there was low lamellar density shadow in posterior segment of the right lobe of the liver, which was non-globular and showed transitional change without positioning effect; the ratio of liver and spleen CT values was 0.365 0. B: Enhancement scanning of the same case of A. It could be distinguished from occupying lesion in the liver."

Figure 2

Diffusion type fatty liverA: This case was diagnosed as mild fatty liver with syndrome of stagnation of liver qi and spleen deficiency. The liver density was reduced widely; the CT value of the liver was lower than that of the spleen; the ratio of the liver and spleen CT values was 0.935 7, between 1.0 and 0.7. B: This case was diagnosed as severe fatty liver with syndrome of phlegmdampness blocking internally. CT scanning showed diffused, severe fatty liver, there was limpid blood vessel shadow; the ratio of the liver and spleen CT values was 0.449 3. C: This case was diagnosed as mild fatty liver with syndrome of interior dampnessheat. CT scanning showed diffused, mild fatty liver; the ratio of the liver and spleen CT values was 0.969 6. D: This case was diagnosed as moderate fatty liver with syndrome of interior dampnessheat. There was undefined blood vessel shadow; the ratio of the liver and spleen CT values was 0.685 2, between 0.7 and 0.5."
