title: Multimodality imaging using ultrasound image fusion in renal lesions.
abstract: OBJECTIVE
  To assess the benefit of ultrasound (US) image fusion in the identifiability and assessment of the dignity of renal lesions.
  
  
  METHODS
  25 patients with 29 renal lesions were investigated using standard US and CEUS (contrast enhanced US) with image fusion (CT or MRI). Identifiability and assessment of dignity was evaluated using cross-sectional images and US separately as well as using both US-techniques with additional image fusion. The respective modality was rated by two experienced radiologists (10 and 5 years of experience) using a (subjective) 5 point rank scale (1 = best).
  
  
  RESULTS
  Using CEUS, image fusion resulted in improved identifiability (score: 1.1 ± 0.4) and improved assessment of dignity (score 1.0 ± 0) of renal lesions than using cross sectional images (score 1.8 ± 1.2 and 3.8 ± 1.2 respectively) separately.
  
  
  CONCLUSIONS
  Image fusion improved the identifiability and the assessment of the dignity of renal lesions compared to using the respective modalities separately.
