What is the main purpose of the 12 month MRI?
For an Acoustic Neuroma of my size, what do you typically see at the 12 month MRI?
What do you see in my MRI?
Does seeing necrosis in the 12 month MRI predict the success of the treatment?
This is my understanding of how things work, but some questions around this maybe worthwhile
Your AN is small, and CK gives a more homogenous dose than GK.
Necrosis or black spots are less likely to occur at 12 months with small tumours, and less likely again with CK due to the better dose distribution. Fast necrosis of the whole tumour is actually undesirable, as rotting meat inside your skull can cause complications. The 12 month MRI is done to ensure there are no complications like hydrocephalus, dramatic tumour
growth and to set a benchmark for the 24m and 36m MRI.
Do not feel discouraged if the tumour is larger and there is no sign of necrosis.
This is fairly typical I believe for a small tumour and your doctor can confirm this with you.
