The purpose of this study was to determine the relationship between segmental hyperintensity of the liver on T1‐weighted images and segmental cholestasis in patients with obstructive jaundice. T1‐weighted and T2‐weighted MR images were obtained of 73 patients with obstructive jaundice caused by various diseases. Fat‐suppressed T1‐weighted images were also obtained of 10 patients. Eleven patients with segmental intra‐hepatic bile duct dilatation (cholestasis) showed segmental hyperintensity on T1‐weighted images and/or fat‐suppressed T1‐weighted images and no signal intensity difference on T2‐weighted images. Sixty‐two patients with widespread intrahepatic bile duct dilatation showed no intensity difference on T1‐weighted and T2‐weighted images ( P < .01). Segmental hyperintensity on T1‐weighted images was correlated with intrahepatic cholestasis.
