Bio banking is the collection of body fluid or tissue samples for research purposes in order to increase our understanding of health and illness. Bio banks have become a valuable resource in medical research, enabling various sorts of cutting-edge studies such as genomics and customised therapy. Blood, urine, skin cells, organ tissue, and other materials are among the specimens kept in a bio bank. The use of MRI to identify which precise regions of tissue should be collected is becoming increasingly common as methods for obtaining tissue specimens become more focused.
