Which radiopharmaceutical is most effective for bone imaging in radionuclide scans?

Show Answers

Gallium-67 (67Ga)Technetium-99m sulfur colloid (99mTc-Sc)Technetium-99m (99mTc) aloneTechnetium-99m combined with Methylene diphosphonate (99mTc-MDP)

Explanation

Among the listed options, Technetium-99m bound to Methylene diphosphonate (99mTc-MDP) is the preferred radiopharmaceutical for skeletal imaging due to its high affinity for bone tissue, making it ideal for detecting bone abnormalities. Other agents like Gallium-67 or plain Technetium-99m are less specific for bone imaging.
