ABSTRACT
Manganese chloride, iron glycerophosphate, and cellulose additive were assessed as base materials for use in a T1-shortening single contrast enema for magnetic resonance (MR) colonography. Contrast-to-noise ratios (CNRs) were compared to those with the standard 10 mmol/L gadolinium-based enema. On T1-weighted three-dimensional gradient-recalled-echo images, CNRs with the iron glycerophosphate enema exceeded those with the manganese- and gadolinium-based enemas. Use of an additive of 0.8% wt/wt cellulose was found to be practicable as it increased viscosity sufficiently without altering CNR. The gadolinium-based enema can be replaced with an iron glycerophosphate enema to render MR colonography less costly.
