In-room imaging and MR planning

Material Quantification Protocols Considerations

• Post-processing:

– Do not change calibration parameters.

• Dedicated kernels. • Pitch should be low (<1). • Slow rotation time (0.5 s) • If possible, narrow collimation should be employed (e.g. to minimize scatter), at the expenses of examination time. • Reconstructed slice thickness S eff .

• Noise and false iodine overlay values. • The main assumption fails in presence of: – Noise – Physical artifacts (beam hardening) – Motion – Contrast media flow
