(18)F-flutemetamol is a positron emission tomography (PET) tracer for in vivo amyloid imaging. The ability to classify amyloid scans in a binary manner as 'normal' versus 'Alzheimer-like', is of high clinical relevance. We evaluated whether a supervi

The most widely studied positron emission tomography ligand for in vivo beta-amyloid imaging is (11)C-Pittsburgh compound B ((11)C-PIB). Its availability, however, is limited by the need for an on-site cyclotron. Validation of the (18)F-labeled PIB d

Regulation of cerebral blood flow in patients with autonomic dysfunction and severe postural hypotension

Autor: Allan R. Andersen, Olaf B. Paulson, Erling Bo Andersen, Birger Hesse, F. Boesen, Jes F. Schmidt, Jesper Mehlsen, Sissel Vorstrup, Gunhild Waldemar

Publikováno v: Clinical Physiology and Functional Imaging. 22:241-247

Background: Whether cerebral blood flow (CBF) autoregulation is maintained in autonomic dysfunction has been debated for a long time, and the rather sparse data available are equivocal. The relationship between CBF and mean arterial blood pressure (M

Publikováno v: Epilepsy Research. 25:41-50

Fifty-eight patients with drug-resistant partial epilepsy were studied preoperatively by interictal rCBF measurements using 99m Tc-HMPAO and a dedicated brain SPECT camera (Tomomatic 64). Follow-up of seizure outcome, using the "Engel score", was at

Publikováno v: Journal of Neurology, Neurosurgery & Psychiatry. 55:1018-1023

Regional cerebral blood flow (rCBF) was studied in 18 patients with Huntington's disease (HD) and 19 age- and sex-matched controls with high resolution single photon emission computerised tomography (SPECT), using Tc-99m-HMPAO. Significant reductions

Publikováno v: Journal of Cerebral Blood Flow & Metabolism. 11:508-521

Single photon emission computed tomography (SPECT) with 99mTc- d,l-hexamethylpropyleneamine oxime (99mTc- d,l-HMPAO) was used to determine global and regional CBF in 53 healthy subjects aged 21–83 years. For the whole group, global CBF normalized t

Publikováno v: Acta Anaesthesiologica Scandinavica. 34:628-631

The influence of the benzodiazepine antagonist flumazenil on regional cerebral blood flow (rCBF) was investigated in ten healthy, alert volunteers. The design was a randomized, placebo-controlled, double-blind, cross-over study. rCBF was measured by
