Pitfalls of pituitary imaging (present and future...)

Following a brief review of pituitary diagnostic imaging and basic magnetic resonance imaging (MRI) semiology, the pitfalls of daily pituitary imaging are further discussed and illustrated. The risk of false positives due to the desire to be highly efficient in detecting micro-lesions, along with the risk of ignoring the complexity of the differential diagnosis of macro-lesions, are the two major pitfalls that should be avoided. Technological progress has generated two recent avenues of improvement, including whole-body MRI at 7 Tesla (7T) and, above all, deep-learning (DL), the promises of which are further discussed on the basis of initial data reported in the literature.
