Imaging of pituitary pathology

Area of Science:

• Radiology
• Neuroimaging
• Endocrinology

Background:

• Pituitary disease diagnosis and management rely heavily on advanced imaging.
• Magnetic resonance (MR) imaging offers superior soft tissue contrast for lesion detection.
• Computed tomography (CT) excels in visualizing calcifications and bony structures.

Purpose of the Study:

• To review the role of MR and CT imaging in pituitary pathology.
• To highlight imaging characteristics of common and rare pituitary lesions.
• To emphasize the importance of imaging in diagnosis, surveillance, and treatment monitoring.

Main Methods:

• Review of MR imaging techniques, including standard and advanced sequences.
• Discussion of CT imaging's strengths in pituitary lesion evaluation.
• Comparison of MR and CT for depicting various pituitary and skull base pathologies.

Main Results:

• MR imaging is the primary modality for pituitary lesions, especially with high-field scanners for microadenomas.
• CT is valuable for detecting calcifications and assessing bony involvement.
• Both techniques are vital for differential diagnosis, including less common tumors and lesions.

Conclusions:

• MR and CT imaging are indispensable tools for comprehensive pituitary disease evaluation.
• Tailored imaging protocols are necessary for accurate diagnosis and monitoring.
• Understanding the strengths of each modality aids in differential diagnosis and surgical planning.
