One hundred thirty-one patients with histologically proved solid sinonasal lesions (56 benign and 75 malignant) who underwent conventional DWI and intravoxel incoherent motion were evaluated. The diffusion coefficient (D), pseudodiffusion coefficient (D*), and perfusion fraction (f) values derived from intravoxel incoherent motion and ADC values derived from conventional DWI were measured and compared. The mean ADC and D values were significantly lower in malignant sinonasal lesions than in benign sinonasal lesions and the mean f value was higher in malignant than in benign lesions. Multiparametric models can significantly improve the cross-validated areas under the curve for the differentiation of sinonasal lesions compared with single-parametric models. The authors conclude that intravoxel incoherent motion appears to be a more effective MR imaging technique than conventional DWI in the differentiation of benign and malignant sinonasal lesions.

This is a retrospective analysis of 59 patients who received only gadobutrol and 60 patients who received only linear gadolinium-based contrast agents. Linear gadolinium-based contrast agents included gadoversetamide, gadobenatedimeglumine, and gadodiamide. T1 signal intensity in the globus pallidus, dentate nucleus, and pons was measured on the precontrast portions of patients' first and seventh brain MRIs. The dentate nucleus/pons signal ratio increased in the linear gadolinium-based contrast agent group while no significant increase was seen in the gadobutrol group. The authors conclude that successive doses of gadobutrol do not result in T1 shortening compared with changes seen in linear gadolinium-based contrast agents.
