Overview
MRI Findings in Pituitary Adenoma
Macroadenoma[1]
- T1
- T1 typically isointense to grey matter
- Larger lesions are often heterogeneous and vary in signal due to areas of cystic change, necrosis, or haemorrhage.
- T1 C+ (Gd)
- A solid components demonstrates moderate to bright enhancement.
- T2
- T2 typically isointense to grey matter.
- Larger lesions are often heterogeneous and vary in signal due to areas of cystic change, necrosis, or haemorrhage.
- T2 gradient echo parameters
- most sensitive for detecting any haemorrhagic components, which appear as areas of signal loss.
- calcification is rare, but should be excluded by reviewing CT scans.
