Question

which applications, either for diagnostic purposes or for therapeutic purposes, involve radioactive materials placed in the body? check all that apply. radiopharmaceuticals mri laser eye surgery external beam radiation therapy lithotripsy brachytherapy radioisotope imaging

Explanation:

Radiopharmaceuticals are drugs containing radioactive materials for diagnosis or therapy and are placed in the body. Brachytherapy involves placing radioactive sources inside the body for cancer treatment. Radioisotope imaging uses radioactive tracers within the body for diagnostic purposes. MRI uses magnetic fields and radio - waves, not radioactive materials placed in the body. Laser eye surgery uses lasers, external beam radiation therapy has an external source, and lithotripsy uses shock waves, none of which involve radioactive materials placed in the body.

Answer:

radiopharmaceuticals, brachytherapy, radioisotope imaging
