Final answer:
In biology, the detection of a 3% to 5% alteration of bone metabolism (mets), known as metabolic hot spots, can be achieved through the use of radioisotopes and PET scans. Radioactive glucose is injected into the body to identify metabolically active tissues, which are depicted as hot spots on PET images. This technique can also help detect cancerous masses due to the high glucose consumption by cancer cells.
Step-by-step explanation:
In the field of biology, the detection of a 3% to 5% alteration of bone metabolism (mets), also known as 'metabolic hot spots,' can be achieved through the use of radioisotopes and imaging technologies such as positron emission tomography (PET).
Radioactive glucose, which is injected into the body, allows medical professionals to identify the tissues that are most metabolically active. These tissues appear as bright 'hot spots' on PET scan images.
This technique can also detect cancerous masses, as cancer cells have a high rate of glucose consumption to fuel their rapid reproduction.
