Conclusion: Patients with normal myocardial perfusion scintigraphy in whom ST-segment depression develops during adenosine stress test appear to have no increased risk for future cardiac events compared with similar patients without ECG evidence of ischemia.

In November 2016, the National Institute for Health and Care Excellence (NICE), the evidence-based organization that provides authoritative national guidance to improve health care quality in the United Kingdom (UK), updated its clinical guideline on the evaluation of patients with chest pain of recent onset. On the basis of a thorough literature review, NICE updated the guideline to recommend coronary computed tomographic angiography (CCTA) as the initial test for all patients without known coronary artery disease (CAD) who present with atypical and typical angina, and for those with nonanginal chest pain who have an abno...

Authors: Kunieda T, Miyake K, Sakamoto H, Iwasaki Y, Iida S, Morise S, Fujita K, Nakamura M, Kaneko S, Kusaka H Abstract Objective To assess the correlation between the angiographic appearance of cerebral collateral pathways or the degree of internal carotid artery stenosis (ICAS) and reduced cerebrovascular reactivity (CVR) estimated by single-photon emission computed tomography (SPECT) image analysis in patients with unilateral ICAS. Methods A retrospective analysis was performed in 42 patients with unilateral ICAS who underwent cerebral angiography and acetazolamide-challenged SPECT of the brain. Cerebral blood ...

We examined the accuracy of the quantitative interpretation using summed differential score in the detection of coronary artery disease (CAD). The attenuation maps were successfully determined in 179 of 183 pa tients (98%). In terms of the vessel-based diagnostic ability, sensitivity, specificity, positive predictive and negative predictive values of the SSPAC and non-correction methods for diagnosing CAD in individual coronary territories were 77%*, 89%, 74%*, and 90%* vs 51%, 87%, 62%, and 82%, respecti vely (*P

CONCLUSIONS: The results of this study suggest that baPWV may have additional value to SPECT for the detection of obstructive CAD, especially in patients with mild ischemia on SPECT. PMID: 28835579 [PubMed - as supplied by publisher]

AbstractPurposeA new method has been developed to calculate fractional flow reserve (FFR) from invasive coronary angiography, the so-called “contrast-flow quantitative flow ratio (cQFR)”. Recently, cQFR was compared to invasive FFR in intermediate coronary lesions showing an overall diagnostic accuracy of 85%. The purpose of this study was to investigate the relationship between cQFR and myocardial ischemia assessed by single-photon emission computed tomography myocardial perfusion imaging (SPECT MPI).MethodsPatients who underwent SPECT MPI and coronary angiography within 3 months were included. The cQFR comput...

AbstractPurpose of ReviewMyocardial blood flow (MBF) quantification with positron emission tomography (PET) is well validated and has established diagnostic and prognostic value for patient management. New cardiac dedicated solid-state single-photon emission tomography (SPECT) cameras using cadmium-zinc-telluride (CZT) crystals have better temporal and spatial resolution and increased count sensitivity than conventional SPECT systems and can measure MBF. We review recent validation studies using CZT technology for measurement of MBF and assess its readiness for clinical application.Recent FindingsOne preclinical study show...
