Malignant tumors with high glucose metabolic rates accumulate [18F]-fluorodeoxyglucose (FDG), a positron emitting tracer. The aim of this study was to evaluate FDG positron emission tomography (PET) for detection and staging of human cholangiocarcinoma (CC). Patients with adenocarcinoma of the biliary tree (n = 26), with benign lesions of the bile ducts (n(More)
Technetium-99m-mercaptoacetylglycylglycylglycine (99mTc-MAG3) is introduced to replace o-iodohippurate (OIH) for renal function studies. For interpretation of clinical findings, extensive pharmacokinetic studies were performed on patients. These showed that 99mTc-MAG3, compared with OIH, has a higher plasma-protein binding, an essentially higher(More)
Eighteen patients suffering from cystic craniopharyngeoma were treated with intracavitary irradiation. The beta-emitting radioisotope 90y (2.25 MeV) was instilled into the cyst following stereotactic puncture of the space-occupying lesion. The surgical approach was planned using angiograms and reconstructed transmission computer tomography (TCT) coronal and(More)
This retrospective study compared standard clinical and biochemical data from 50 graft recipients against 533 I-131 Hippuran sequential scintigrams and 515 [99mTc]pertechnetate serial scintigrams. All grafts included in this study are cadaver kidneys. The majority of the studies were made during the early posttransplantation period. Anuria or oliguria of at(More)
First clinical results indicated that among all potential 99mTc-complexes the N3S-complex 99mTc MAG3 has the biokinetic properties most similar to o-I-hippurate (OIH). A simultaneous comparison of 99mTc MAG3 and 131I OIH was conducted in a series of 48 patients. Twelve out of 18 transplant patients received simultaneously both radiopharmaceuticals for(More)
Previous studies have indicated pre-existing subclinical Graves' disease (GD) in many patients with the scintigraphic diagnosis of disseminated thyroid autonomy (DISA) or toxic multinodular goitre (TMG) type A. After radioiodine (RAI) treatment, an increase or the induction of TSH-receptor antibodies (TRAbs) in patients with GD or TMG has been repeatedly(More)
Distinguishing Graves' disease (GD) from a toxic multinodular goiter (TMG) subgroup with a diffuse but uneven Tc-distribution depends on the diagnostic power of the TSH-receptor antibody (TRAb) determination. Bioassays using CHO cell lines expressing the hTSH-receptor or a new TBII assay, which uses the hTSH-receptor as an antigen (DYNOTEST TRAK human,(More)
Hippurate function scintiscans were obtained in prone and standing positions in a group of 76 patients with concurrent hypertension and nephroptosis. TWelve of these patients had massive, bilateral disturbance of intrarenal hippurate transport in the standing position; hippurate transport was normal in the prone position. This pattern was present in only(More)
Hallervorden-Spatz disease (HSD), a rare extrapyramidal motor illness, is usually only confirmed after death. In vivo diagnosis has relied hitherto on the combination of typical magnetic resonance imaging (MRI) findings (the "eye of the tiger" sign) and heterogeneous clinical symptoms of movement disorder which have been regarded as almost pathognomonic. We(More)
