Thirty eight patients with known or suspected phaeochromocytoma were studied by radioisotope imaging after intravenous administration of iodine-131-meta- iodobenzylguanidine (131I- mIBG ), a radiopharmaceutical which has affinity for chromaffin tumours. Seventeen positive results (including one false positive) and 21 negative results (including two false… (More)
Meta-iodobenzylguanidine, a guanethidine analogue, is a newly synthesised substance capable of imaging the adrenal medulla. In a woman in whom phaeochromocytoma has been diagnosed iodine-131-labelled metaiodobenzylguanidine was given intravenously; gamma-camera images showed bilateral adrenal tumours and uptake corresponding to bone and liver metastases.… (More)
A prospective study was performed to evaluate the use of radionuclide imaging in the assessment of patients who have undergone esophageal reconstruction. Dynamic radionuclide imaging was performed on ten patients aged 11 months to 11 years who had undergone colon interposition via the normal esophageal route for esophageal atresia. Patients were considered… (More)
Peptide analyses have been carried out for chymotryptic digests of transferrin C and transferrin D(1). There is a difference in one peptide, and amino acid analyses indicate that an aspartic acid residue in transferrin C is replaced probably by a glycine residue in transferrin D(1).
