Dynamic MRI of the diaphragm.
OBJECTIVE
To demonstrate the appearance of the diaphragm on single-slice dynamic MRI.


METHODS
We evaluated the diaphragm using gadolinium-enhanced single-slice dynamic MR in 53 patients.


RESULTS
The diaphragm was partially depicted in 49 cases (92.5%). Its thickest part measured 4.4 +/- 2.2 mm, range 3 to 15 mm. Enhanced high-intensity thin layer structures were partially identified between the diaphragm and liver parenchyma in 46 cases (86.8%) at 16 to 144 s (mean +/- SD, 65.7 +/- 32.6 s) after intravenous injection of Gd-DTPA.


CONCLUSIONS
Dynamic MR has value and limitations in demonstrating the diaphragm.
