Do you need to defecate before lumbar photography?

Need. Defecation can help clear the gas and feces in the intestine and avoid interference with the lumbar image. The lumbar spine is located between the abdomen and pelvis, and the gas and feces in the intestine will block or artifact the image of the lumbar spine, which will affect the accuracy of diagnosis. Defecation helps to reduce this interference and improve the clarity and diagnostic accuracy of lumbar images.
