M.D.; TAYLOR, ANDREW Jr. M.D.Author Information From the Division of Nuclear Medicine, Department of Radiology, the University of Utah School of Medicine, Salt Lake City, Utah Clinical Nuclear Medicine: November 1985 - Volume 10 - Issue 11 - p 804-806 Buy Abstract Accumulation of radioactive urine in a bladder diverticulum on a Tc-99m pertechnetate scan simulated uptake in a Meckel's diverticulum. The abnormal activity was present even following bladder catheterization and drainage. However, saline lavage washed the residual activity out of the bladder, and prevented a false-positive diagnosis. In addition to preventing false-positive studies, bladder lavage may increase the sensitivity of the test by allowing the detection of Meckel's diverticuli that are obscured by residual bladder activity. © Lippincott-Raven Publishers.
