Objective:
To demonstrate the appearance of the diaphragm on single-slice dynamic MRI.
Materials And 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.
Conclusion:
Dynamic MR has value and limitations in demonstrating the diaphragm.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
