Hi, I am working on a project to segment tumours and livers automatically in FLASH axial images of mouse livers. There is progressive signal loss as I approach the bottom-most slices in a 45 slice image.
I have attached a figure with slices from a single MRI scan and image acquisition parameters in case it comes in handy.
Can you please help me Identify the phenomenon that is causing this signal loss? E.g. Is it Magnetic Field Inhomogeneity? Crosstalk? Is it the positioning of the coil around the mouse abdomen?
Do you have any suggestions on post-processing to correct for this?
If I can know the cause, I can do the research to come up with an image processing solution. Your help is greatly appreciated!
