Overview
MRI
- MRI is the imaging procedure of choice in diagnosis of hypopituitarism. It is preferred over the CT scan as optic chiasm, pituitary stalk, and cavernous sinuses can be seen in MRI.[1]
- A magnetic resonance imaging (MRI) scan may show a three-dimensional image of pituitary gland, hypothalamus, and the organs near them.
- MRI is used to detect the underlying cause of hypopituitarism like the pituitary adenoma.
- MRI scan shows the following findings in cases of hypopituitarism:[2]
- Decreased size of the pituitary gland.
- Empty sella may be noticed in some cases.
- Pituitary stalk may be visible, thin, or totally abscent.
- Posterior lobe of the pituitary may be abscent.
