In MRI, it was shown in the 1960s that the relaxation time difference between tumor and normal tissue occurs in which decade?

Magnetic resonance imaging derives contrast from how protons relax after being excited. The key idea being tested is that different tissues have different relaxation times, so tumors can show distinct relaxation behavior compared with normal tissue. In the 1960s, researchers demonstrated that malignant tissue often has different longitudinal (T1) and transverse (T2) relaxation times than normal tissue, due to factors like altered water content, cellular density, and the tumor microenvironment. This early observation showed that MRI could differentiate tumor from normal tissue based on relaxation properties, laying the groundwork for MRI as a diagnostic tool.
