A sequential double-label autoradiographic method that quantifies altered rates of regional glucose metabolism
(Elsevier, 1985-12-30)
An autoradiographic sequential double-label variant of the deoxyglucose method for measurement of local glucose utilization has been developed. This technique takes advantage of the short half-life of the positron emitter, ...
In vivo measures of dopaminergic radioligands in the rat brain: Equilibrium infusion studies
(John Wiley & Sons, Inc., 2002-03-01)
The application of an equilibrium infusion method for measuring specific in vivo radioligand binding in the conscious rat brain was evaluated for two ligands of the dopaminergic system, (+)-Α-[ 11 C]dihydrotetrabenazine ...
PET and P300 relationships in early Alzheimer's disease
(Elsevier, 1990)
The P300 (P3) wave of the auditory brain event-related potential was investigated in patients with probable Alzheimer's disease to determine whether P300 latency discriminated these patients from controls and whether ...
Granulocytic sarcoma (chloroma) causing spinal cord compression
(Springer-Verlag, 1993-08)
Granulocytic sarcoma (chloroma) is a rare solid tumor of myelogenous stem cells, usually appearing in patients with acute myelogenous leukemia and less commonly in patients with chronic myelogenous leukemia or myeloproliferative ...
A densitometer for quantitative autoradiography
(Elsevier, 1983-11)
A low cost spot densitometer system is described. This system is useful for quantitative autoradiography of local cerebral glucose utilization, blood flow, receptor binding and other applications requiring densitometry on ...
Changes in medial cortical blood flow with a stimulus-response compatibility task
(Elsevier, 1994-02)
Previous work has suggested that human subjects engaged in tasks, like the Stroop task, that require response selection utilize the medical frontal cortex. We used positron emission tomography to measure blood flow changes ...
Intratumoral injection of BCNU in ethanol (DTI-015) results in enhanced delivery to tumor – a pharmacokinetic study
(Kluwer Academic Publishers; Springer, 2005-07)
Solvent facilitated perfusion (SFP) has been proposed as a technique to increase the delivery of chemotherapeutic agents to tumors. SFP entails direct injection of the agent into the tumor in a water-miscible organic ...
Vertebrobasilar arterial occlusions in children
(Springer-Verlag, 1974-12)
Three children with angiographically confirmed, sudden thrombosis involving the vertebro basilar arterial system are presented. Ten previously reported cases are reviewed with particular regard to possible etiologies. ...
Inhibition of Neutral Amino Acid Transport Across the Human Blood-Brain Barrier by Phenylalanine
(Blackwell Science Ltd, 1995-03)
The delivery of large neutral amino acids (LNAAs) to brain across the blood-brain barrier (BBB) is mediated by the L-type neutral amino acid transporter present in the membranes of the brain capillary endothelial cell. In ...
Cerebrospinal fluid abdominal cyst. Computed tomographic resolution of a sonographic dilemma
(Elsevier, 1984-04)
A case of subhepatic cerebrospinal fluid cyst, an uncommon complication of ventriculoperitoneal shunting, is presented. Sonography could not reliably prove shunt tubing to be entering the cystic spaces. Results of computed ...
