title: Loculation as a contraindication intracavitary 32P-chromic phosphate therapy.
abstract: Loculation of instilled 99mTc-sulfur colloid solution in the peritoneal cavity was observed in a patient being considered for intracavitary therapy with 32P-chromic phosphate. Since intracavitary instillation of a therapeutic dose of a radiopharmaceutical agent into a loculated space would risk therapeutic failure and tissue necrosis, prior instillation of a tracer nuclide is recommended to insure adequate dispersion before beginning such therapy.
