title: In vivo assessment of 99mTc-labeled hematoporphyrin derivative in tumor-bearing animals.
abstract: The efficacy of 99mTc-labeled hematoporphyrin derivative in localizing neoplasms has been investigated with tumor-bearing animal models. Spontaneous mammary adenocarcinomas of outbred CFW strain Swiss-Webster white mice and chemical carcinogen induced breast tumors in female Sprague-Dawley white rats were clearly visualized in the scintigrams. Mice tissue distribution data demonstrate favourable tumor to organ ratios sufficiently high to permit tumor detection. [99mTc]HPD appears promising as a tumor imaging agent.
