I believe that it is Soft tissue images and Treatment of cancer.(technically antibiotic us is correct for the treatment of cancer, but I am going on a limb and saying it is not.)
Here are some of the many uses of radioactive elements in health care.
1) Soft tissue imaging
Health professionals use radioactive ¹⁸F in positive emission tomography (PET) scans to PET to detect and evaluate most cancers and to provide images of the heart and brain.
2) Diagnosis of disease
Health professionals use radioactive ¹³¹I to diagnose thyroid disorders.
3) Antibiotics
Biochemists use radioactively labelled antibiotics to determine how they are used and metabolized by the body.
4) Treatment of cancer
Health professionals use ¹³¹I to treat certain types of thyroid cancer. They also use ⁸⁹Sr, ¹⁵³Sm, and ²²³Ra to treat various types of bone cancer.
