Noncontrast MRI Surveillance of Craniopharyngiomas Using a Balanced Steady-state Free Precession (bSSFP) Sequence.

ABSTRACT:

Background and purpose

Contrast-enhanced MRI (CEMRI) is a commonly used imaging technique for craniopharyngioma surveillance; however, it carries risks such as allergic reaction and gadolinium deposition. This study evaluates the efficacy of non contrast-enhanced MRI (NCMRI) with a balanced steady-state free precession (bSSFP) sequence compared with CEMRI T1-weighted imaging for craniopharyngioma surveillance.

Materials and methods

Twenty-nine patients with craniopharyngioma (16 females/13 males, mean age =21.5 ± 4.3 years) with CEMRIs, including a bSSFP sequence, were evaluated. For each patient, 2 blinded neuroradiologists compared the dimensions of residual craniopharyngioma on non-contrast- and contrast-enhanced sequences. Tumor volume and solid/cystic component measurem
