CHST member gave a virtual talk to the Rochester Institute of technology, US regarding the topic, “Chemical Exchange Saturation Transfer (CEST) Magnetic Resonance Imaging (MRI) for Stroke and Cancer Diagnosis” on 14 Oct 2020, 3.30 – 4.30 pm.
Many participants joined the talk and asked questions about the potential of the novel imaging technique discussed in stroke and cancer diagnosis.
CEST MRI allows the detection of labile protons in our body that has a concentration much lower than the water protons which consists of about 70 – 80% of our body. Conventionally, MRI is used to detect the water signal because they are abundant in the body. The introduction of CEST MRI allows the indirect detection of labile protons that are previously undetected by MRI. The detected CEST MRI signal has been shown to have better potential than the current clinical practice in identifying tissue at risk after an ischemic stroke and in grading tumour, differentiating tumour regrowth and radiation necrosis, and measuring extracellular pH of tumour microenvironment. In this talk, CEST MRI will be introduced and shown how it can be used to improve stroke and cancer diagnosis.
