●● Bone marrow
, Answer: Sulfur colloid 10mci
●● In-111 Leukocyte labeling normal distribution
Answer: - Intense activity in the spleen, liver, and bone marrow
- Extravasation may result in a false- negative
- Damage to WBC can be avoided by injecting slowly through a large
gauge needle
- tracer of choice when imaging the abdomen
●● Normal distribution of Ga-67 citrate
Answer: intense liver uptake, nasopharynx, lacrimal/ salivary glands,
Bony thorax bones, kidneys up to 48 hrs, colon, and pelvis
- after 48 hrs kidney activity indicates disease
