Sensitivity of Multiphase Pseudocontinuous Arterial Spin Labelling (MP pCASL) Magnetic Resonance Imaging for Measuring Brain and Tumour Blood Flow in Mice
Figure 5
Application of the MP pCASL sequence in mice with intracerebral 4T1-GFP metastatic tumours showing gadolinium enhancement. (a) T1-weighted image showing enhancement (dotted outline) of metastatic foci. (b) CBF maps with the same ROI indicated. (c) Graph showing CBF values in tumour and contralateral regions; no significant decrease in perfusion is evident (d-e). Histological comparison of microvessel area fraction in tumour (d), and contralateral (e) regions. Scale bars = 20 µm. (f) Graph showing quantitation of microvessel area fraction in tumour and contralateral striatum regions; a significant increase in microvessel area fraction is evident in tumour compared with normal tissue in the contralateral striatum (). .
