WebOct 31, 2024 · (5) Biological gradient ("dose-response"). The more a person is exposed to A, the likelier he should be to get disease B. The more cigarettes a person smokes, the likelier he is to get lung cancer. This notion, known as dose-response, presents another challenge to endocrine disruptors. WebGradient echo (GRE) sequences begin as a regularly spaced series of radiofrequency (RF)-pulses repeated at time interval TR. These RF-pulses are often chosen to have flip angles (α) less than 90°, but can have any value. A train of evenly spaced RF pulses produce "FID-like" and "Echo-like" signals. Each RF-pulse generates a free induction ...
