MRI measurements of vessel calibre in tumour xenografts: Comparison with vascular corrosion casting

► Non-invasive quantitation of vessel calibre in tumour xenografts in vivo ► Assessment of tumour vessel calibre response to a vascular disrupting agent ► Generation of vascular corrosion casts from the same tumours imaged by MRI ► Quantitation of vessel calibre from corrosion casts by microCT ► Excellent agreement between the in vivo MRI and post mortem microCT vessel calibres
