Autor: Liam S. P. Lawrence, Lee C. L. Chin, Rachel W. Chan, Timothy K. Nguyen, Arjun Sahgal, Chia-Lin Tseng, Angus Z. Lau

Publikováno v: Radiation Oncology, Vol 16, Iss 1, Pp 1-7 (2021)

Abstract Background Clinical target volume (CTV) contouring guidelines are frequently developed through studies in which experts contour the CTV for a representative set of cases for a given treatment site and the consensus CTVs are analyzed to gener

Chemical Exchange Saturation Transfer MRI for Differentiating Radiation Necrosis From Tumor Progression in Brain Metastasis-Application in a Clinical Setting

Autor: Hatef Mehrabian, Rachel W. Chan, Arjun Sahgal, Hanbo Chen, Aimee Theriault, Wilfred W. Lam, Sten Myrehaug, Chia‐Lin Tseng, Zain Husain, Jay Detsky, Hany Soliman, Greg J. Stanisz

Publikováno v: Journal of magnetic resonance imaging : JMRIREFERENCES.

High radiation doses of stereotactic radiosurgery (SRS) for brain metastases (BM) can increase the likelihood of radiation necrosis (RN). Advanced MRI sequences can improve the differentiation between RN and tumor progression (TP).To use saturation t

Deuterium MRS of early treatment‐induced changes in tumour lactate in vitro

Autor: Colleen Bailey, Rachel W. Chan, Daniel Djayakarsana, Angus Z. Lau, Hanzhi Wang, Josephine L. Tan

Publikováno v: NMR in Biomedicine. 34

Elevated production of lactate is a key characteristic of aberrant tumour cell metabolism and can be non-invasively measured as an early marker of tumour response using deuterium (2 H) MRS. Following treatment, changes in the 2 H-labelled lactate sig
