Morphometric of hepatic duct angulation & relative pathologies incidence among sudanese population

The morphometric of hepatic ducts angle has been measured and related to some pathologies for the importance of overcoming some further invasive techniques and deducing valuable diagnostic findings. Measurement carried out of contrasted MRI for hepatic ducts angle, gallbladder volume, tumor diameter, stone diameter using ImageJ\ImageJ.exe software program; by drawing two lines running within the origins of both Right and Left hepatic ducts and crossing at biliary confluence angle on coronal oblique images in addition to gender, age, common diagnosis of liver. The results analysis using EXCELL program revealed that: females are more susceptible to GB and liver diseases (57%), hepatic diseases observed at 7-12 years old (1.8%); and peaking at 37-42 years old (20.4%) then decreases following aging. GB diseases implied stone (27.2%), cancer (17.7%), jaundice (15.5%) and PSc (7.7%). The average normal gallbladder volume (GBV) was 22 cm3 relative to hepatic duct angle (45˚), jaundice induced GBV of 36 cm3 relative to (73˚), tumor induced GBV of 68 cm3 relative (84˚) and the stone induced a GBV of 78 cm3 relative to (94˚). The effect of stone and tumor diameters in the hepatic duct angle with significant correlation (R2 = 0.8) in a linear proportional form fitted in the equations: y=0.85x+84 for stones and y=0.81x+65 for tumors; where x refers to stone/tumor diameter in mm and y refers to relative hepatic angle.
