Final answer:
99mTc Sulfur colloid is not used for myocardial perfusion imaging; other tracers like thallium-201 are preferred for this purpose.
Step-by-step explanation:
The procedure that 99mTc Sulfur colloid is not typically used for is D) Myocardial perfusion imaging. 99mTc Sulfur colloid is commonly used for liver-spleen scanning and can also be employed for bone marrow imaging, but it is not the preferred agent for myocardial perfusion imaging. Instead, other radioactive tracers, such as thallium-201 (201 Tl) or other technetium-based compounds like technetium-99m sestamibi, are used for assessing heart tissue and function. This is because these agents become concentrated in healthy heart tissue and can assist in evaluating coronary artery blockages.
