Pediatric Pituitary MRI Protocol with & without contrast

Without Contrast "Pediatric Pituitary MRI"

• T1 Sagital 3mm
• T1 Coronal 3mm
• T2 Coronal 3mm
• T1 Axial 5mm (Occasionally according to the lesion T2 Axial 5mm also used) 
• T1 weighted three-dimensional gradient echo MRI technique (FSPGR)

Post Contrast "Pediatric Pituitary MRI"

• T1 weighted three-dimensional gradient echo MRI technique (FSPGR)
• T1 Sagital 3mm
• T1 Coronal 2mm

Technical notes for "Pediatric Pituitary MRI"

• In "Pediatric Pituitary MRI" we used to do all the sequences Spin Echo.
• The anterior and posterior portions of the gland were not measured separately, because the small size of the gland and the relative isointensity of the two portions of the gland in a large number of infants precluded separate measurements of these structures.
• The T1-weighted sagittal sequence was used to measure both the anteroposterior diameter and the height.
• The width was measured from either axial or coronal images
• ACTH producing pituitary adenomas are the most common cause of Cushing's Syndrome in childhood. Although Gadolinium-DTPA (Gd) enhanced T1 weighted spin echo magnetic resonance imaging (SE-MRI) has proven to be the most sensitive imaging modality for localizing pituitary adenomas, its diagnostic accuracy does not exceed 40-50% in detecting Cushing's disease (CD)
