CONCLUSIONS: Our results suggest that a defined compensatory stage of cerebral ischemia might be useful for the prognosis of patients receiving EI-CI bypass surgery. PMID: 30010157 [PubMed - as supplied by publisher]
Rhenium and technetium complexes of thioamide derivatives of pyridylhydrazine that bind to amyloid-β plaques. J Biol Inorg Chem. 2018 Jul 07;: Authors: Fletcher SP, Noor A, Hickey JL, McLean CA, White JM, Donnelly PS Abstract Age-associated deposition of amyloid-β in cerebral blood vessels, a condition referred to as cerebral amyloid angiopathy, can contribute to stroke and dementia. This research aimed to design new radioactive technetium-99 m complexes that bind to amyloid-β plaques that have the potential to assist in diagnosis of cerebral amyloid angiopathy using single-photon-...
Conclusions: 99mTc-rhAnnexin V-128 imaging is safe with no observed adverse events or lab result changes. 99mTc-rhAnnexin V-128 imaging of apoptosis is feasible with excellent image quality at one and 2 hours following tracer injection. Significant focal uptake was identified in 1/12 patients and none of the 5 controls. Quantitative analysis of the planar images showed significantly greater uptake of annexin in patients compared to controls for both carotid arteries and at one and two hours.
Conclusions: Results show that FGA has a potential to enable extremely sensitive and high resolution neuroimaging of brain infarcts. F-18-labeled FGA can be rapidly synthesized from ubiquitously available F-18-FDG in a simple reaction.
Conclusions: About 1 in 5 patients undergoing PET MPI are referred for coronary angiography within 90 days of testing, a rate greater than that reported for SPECT MPI, likely due to higher baseline risk of patients undergoing PET MPI testing. While referral rates for coronary angiography varied based on the presence or absence of prior documented clinical CAD and presence of test abnormalities, nearly 36% of patients with moderate-severe ischemia were not referred. Further work is needed to characterize why such patients are not referred for invasive evaluation to optimize the use of PET MPI in this high-risk population.
Conclusions: These results are consistent with the hypothesis that microglial cells bearing CD206 trap fluorescent-labeled Tc-99m-tilmanocept in regions of BBB disruption. This provides the motivation for a clinical trial of intra-venously administered Tc-99m-tilmanocept with the goal of developing a SPECT/CT protocol for the detection of neuro-inflammation.
CONCLUSIONS: CABG can be performed at an acceptable risk in patients with brain hypoperfusion. However, these patients suffered high stroke incidence during the follow-up. It is therefore, important to identify those patients preoperatively to plan and implement an appropriate treatment regime. PMID: 29616518 [PubMed - as supplied by publisher]
, Bene O, Kertész A, Édes I Abstract Dilated cardiomyopathy is the main cause of heart transplantation. The etiology is unknown in almost half of the cases. Many cardiac specific antibodies have been identified till now which can cause decreased cardiac function, ventricular tachycardia or sudden heart death. The prognosis of DCM is poor despite the development of medical treatment. Immunoadsorption is hopeful since, with the removal of antibodies, cardiac function and NYHA class can improve and LVAD/heart transplantation-free survival can be prolonged. At the University of Debrecen, Faculty of Medic...

In readinglast year's RSNA report, I was struck with just how little has changed.Here I am this year, 2017, and here's how I looked at RSNA 2016:A little grayer, perhaps a pound or two more. But otherwise same ol'Dalai. And same ol'RSNA. I even manned the RAD-AID booth again:Yes, I tied the bow-tie all by myself.This is a model housed at the Bayer booth of the airship RAD-AID hopes to use to bring imaging to underserved areas; I think the official rendering is much more impressive, and maybe even a little, well,buxom:I'm still lobbying for a seat on the first flight. Did I saybuxom? I meanthandsome!I did attend the requisi...
