AB  - BACKGROUND: The haemodynamics determined by different approaches for studying 
      fluid dynamics - i.e. computational fluid dynamics (CFD), particle image 
      velocimetry (PIV), and phase-contrast magnetic resonance imaging (PC-MRI) - have 
      rarely been thoroughly compared; nor have the factors that affect accuracy and 
      precision in each method. As each method has its own advantages and limitations, 
      this knowledge is important for future studies to be able to achieve valid 
      analyses of fluid flows. OBJECTIVE: To gauge the capacity of these methods for 
      analysing aneurysmal flows, we compared the haemodynamic behaviours determined by 
      each method within a patient-specific aneurysm model. METHODS: An in vitro 
      silicone aneurysm model was fabricated for PIV and PC-MRI, and an in silico 
      aneurysm model with the same geometry was reconstructed for CFD. With the same 
      fluid model prepared numerically and physically, CFD, PIV and PC-MRI were 
      performed to study aneurysmal haemodynamics. RESULTS: 2D velocity vectors and 
      magnitudes show good agreement between PIV and CFD, and 3D flow patterns show 
      good similarity between PC-MRI and CFD. CONCLUSIONS: These findings give 
      confidence to future haemodynamic studies using CFD technology. For the first 
      time, the morphological inconsistency between the PCMRI model and others is found 
      to affect the measurement of local flow patterns.
