Sporadic Creutzfeldt-Jakob disease (sCJD) is the most common form of human prion disease; it is characterized as a transmissible spongiform encephalopathy. Previously, only two case reports have discussed crossed cerebellar diaschisis (CCD) and sCJD. Herein, we detected CCD in five patients with sCJD and four patients with genetic CJD through SPECT. The combined data of the nine patients further supported CCD when analyzed by 3D-SSP. CCD can occur in several disorders, including, stroke, epilepsy, and encephalitis.

AbstractBackgroundWe investigated the feasibility of left ventricular (LV) and right ventricular (RV) volume and function estimation using a first-pass gated15O-water PET. This prospective study included 19 patients addressed for myocardial perfusion reserve assessment using15O-water PET. PET data were acquired at rest and after regadenoson stress, and gated first-pass images were reconstructed over the time range corresponding to tracer first-pass through the cardiac cavities and post-processed using TomPool software; LV and RV were segmented using a semi-automated 4D immersion algorithm. LV volumes were computed using a ...

AbstractObjectiveWith the advancement of reperfusion therapy in stroke patients, assessment of perfusion status after therapy is gaining importance. Hyperperfusion tends to be underestimated by the conventional early imaging of123I-IMP brain perfusion SPECT. We evaluated the utility of super-early imaging as an adjunct to early imaging for the assessment of postischemic hyperperfusion in stroke patients.MethodsSixty-seven patients who underwent123I-IMP brain perfusion SPECT within 14 days after the onset of cerebral infarction were retrospectively analyzed. Super-early (4 –10 min) and early (15–45 min...

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.
