Abstract：Objective To find the best positioning reference point in the chest photography after PICC replacement by measur-ing CT images.Methods From January 2015 to June 2015, the physical examination data of 213 cases with chest CT examina-tion were collected to measure and analyze the lengths from the intercostal space between the 6 th and 7 th posterior fib, the 6 th right posterior fib, the 7 th right posterior fib to Cavoatrial junction( CAJ) .Results The lengths from the intercostal space be-tween the 6 th and 7 th posterior fib, the 6 th right posterior fib, the 7 th right posterior fib to CAJ were (19.446 ±14.4981) mm, (28.232 ±16.7217) mm, (13.741 ±11.1473) mm, the difference had statistically significant (χ2 =93.793, P =0.000).In the four groups, the percent of cases, whose lengths were 0~20 mm, were 45.5%, 31.9%, 43.2%, and the per-cent of cases, whose lengths were <0 mm, were 14.6%, 4.2%, 39.4%, the difference had statistically significant (χ2 =11.040, P =0.000).Conclusion The intercostal space between the 6 th and 7 th posterior fib is the better choice than the 6 th right posterior fib and the 7 th right posterior fib as the positioning reference point after PICC replacement.
