Cantlie line

Cantlie's Line is an anatomical landmark used in medical imaging and surgical procedures involving the liver. It is named after the British surgeon James Cantlie, who first described it in the late 19th century.

Description

Cantlie's Line is a virtual line drawn on the surface of the liver from the middle of the gallbladder fossa to the inferior vena cava. It divides the liver into two roughly equal halves: the left lobe and the right lobe. This division is not the same as the functional division of the liver into the left and right lobes, which is based on the distribution of the hepatic artery, portal vein, and bile ducts.

Clinical Significance

Cantlie's Line is used in liver surgery to guide the division of the liver parenchyma. It is also used in radiological imaging to identify and describe the location of liver lesions. The line can be visualized on ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI).
