  • Title: Pelvic lesion simulated by asymmetric marrow uptake following umbilical artery injection of technetium-99m sulfur colloid.
    Author: Vachon L, Colletti P.
    Journal: Clin Nucl Med; 1986 Dec; 11(12):872. PubMed ID: 3815986.
    Abstract:
    There is avid first-pass extraction of Tc-99m sulfur colloid by bone marrow. This factor must be considered when injection of the isotope is made via an unusual route. Tc-99m sulfur colloid was injected via an umbilical artery catheter into an infant's left iliac artery, causing marked marrow uptake in the left pelvis. The paucity of uptake on the right side of the pelvis simulated metastatic replacement of the marrow. A repeat study done via the jugular vein demonstrated no abnormalities of pelvic marrow uptake.
