Comparison of MRI and US techniques to image mice bearing CT26 tumours.
| Method | Spatial resolution (mm) | Smallest detectable tumour (volume mm3) | Analysis time (min) | Main advantages | Main disadvantages |
|---|---|---|---|---|---|
| MRI | 0.123 | 14.47 | 15 | (i) Real 3D volume (ii) Anatomic information (iii) Complementary data, functional information |
(i) Expertise needed (ii) Duration of data analyses (iii) Operating cost |
|
| |||||
| US | 0.100 | 4.19 | <5 | (i) User friendly technique (ii) Volume can be measured directly |
(i) Volume estimation (ii) Hairless mouse or shaved zone of observation needed (iii) Poor resolution |
