title: Body-background defects with 99mTc-DTPA after renal transplantation: case reports.
abstract: Photon-deficient areas adjacent to transplanted kidneys were seen in the early phases of several dynamic studies obtained with 99mTc-diethylenetri-aminepentaacetic acid (99mTc-DTPA). The causes included hematoma, urinoma, and lymphocele. These fluid collections do not readily exchange as part of the extracellular space and, if sufficiently large, may be visualized as photon-deficient areas in the normally homogeneous background of 99mTc-DTPA studies.
