RT Journal Article SR Electronic T1 Occult Intestinal Bleeding Imaged by Technetium-99m-HSA-D Radionuclide Angiography: A Case Report JF Journal of Nuclear Medicine Technology JO J. Nucl. Med.

Sometimes the results produce unexpected information. This information is helpful when considering the clinical perfusion pathophysiology. Recently, we were able to detect an intestinal bleeding lesion clearly for a patient by using RNA.
