From the case: Enhancing subdural effusions
Axial T1 C+
The upper head was imaged for 10 minutes before, during and after gadolinium administration with a T1-weighted 3D spoiled gradient echo sequence at a temporal resolution of 8 seconds. The contrast agent slides down the outer membrane of the subdural effusions accumulating in the posterior aspect of the collections. This is better appreciated on the left side while scrolling through the images to advance in time.
