WB Skeletal Imaging - Contamination

Clinical History: 73 year old female with low back pain.

Technique: 3phase and whole body bone scan performed following injection of 23 mCi MDP.

Findings: The dynamic blood flow study and immediate post injection scan of the lower back demonstrate no evidence of a focally increased blood flow of increased vascularity. Bone imagings from the head to toes demonstrate a slightly increased tracer uptake involving the lower lumbar spine at the level of L4 and L5, probably due to degenerative bone and joint disease. Slightly increased tracer uptake involving both shoulder joints, probably non-specific arthritis. No abnormal tracer uptake is noted in the sacrum and coccyx.

Slightly increased tracer uptake involving patient's boots. The patient was on lasix, and urinated through her pantyhose. She went home and changed her hose prior to imaging. She did not change her boots, therefore only the boots show contamination and not her hosiery.
