Introduction to the D-SPECT for Technologists: Workflow Using a Dedicated Digital Cardiac Camera.

Introduction to the D-SPECT for Technologists: Workflow Using a Dedicated Digital Cardiac Camera. J Nucl Med Technol. 2020 Oct 05;: Authors: Johnson RD, Bath NK, Rinker J, Fong S, St James S, Pampaloni MH, Hope TA Abstract Coronary artery disease (CAD) is the leading cause of death in the United States (1). Myocardial perfusion imaging (MPI), using single photon emission computed tomography (SPECT) is one of the most frequently used diagnostic tools for patients at risk for CAD, and has significant prognostic value (2). Dedicated cardiac SPECT cameras such as the D-SPECT have been specifically designed for MPI studies. Equipped with new technology, the D-SPECT camera has demonstrated superior image quality when compared to standard SPECT or SPECT/CT cameras, while reducing patient and personnel radiation exposure and decreased imaging time (3). In this continuing education article focuses on the specifications of both SPECT/CT and D-SPECT camera systems, radiopharmaceutical dosing requirements, imaging workflows and some disadvantages of utilizing each camera system.

Authors: Czaja-Ziółkowska MZ, Wasilewski JP, Głowacki J, Wygoda Z, Gąsior M Abstract The first part of the review concerning myocardial imaging by single photon emission computed tomography (SPECT) discussed the basic aspects of interpretation of left ventricular perfusion disorders in stress and rest examination. The second part presented the interpretation of gated SPECT imaging in relation to the assessment of systolic and diastolic left ventricular functions. The third part concerns the assessment of myocardial viability and phase analysis from gated SPECT in the qualification of patients with left ventr...

ConclusionSuspect CMD was not associated with more negative psychological factors compared to other groups. State sadness was significantly higher for patients with suspect CMD, whereas no differences in state anxiety and other psychological factors were found.

CONCLUSIONS AND RELEVANCE: Neuropsychological testing and MRI remain the most widely used diagnostic tests by DLB specialists. Other tests-particularly indicative biomarkers-are used only selectively. Research is needed to validate existing potential DLB biomarkers, develop new biomarkers, and investigate mechanisms to improve DLB diagnosis. PMID: 33009039 [PubMed - as supplied by publisher]

AbstractPurpose of ReviewEstablishing a diagnosis of ischemic heart disease (IHD) in women, including assessment for coronary microvascular dysfunction (CMD) when indicated, can be challenging. Access to performance of invasive testing when appropriate may be limited, and noninvasive imaging assessments have evolved. This review will summarize the various noninvasive imaging modalities available for the diagnosis of IHD and CMD in women, outlining indications, performance modalities, advantages, and limitations.Recent FindingsWhile stress echocardiography and single photon emission computed tomography (SPECT) myocardial pe...

Authors: Heizer J, Carbone S, Billingsley HE, van Tassell BW, Arena R, Abbate A, Canada JM Abstract BACKGROUND: Left ventricular (LV) concentric remodeling refers to a process by which increased LV relative wall thickness alters myocardial geometry, resulting in reduced LV end-diastolic volume (LVEDV) and stroke volume (SV). While the degree of concentric remodeling is a negative prognostic factor in heart failure with preserved ejection fraction (HFpEF), it is not known how it contributes to cardiorespiratory fitness (CRF). METHODS: We performed a retrospective analysis of patients with HFpEF who underwent tre...

This article discusses the measurement of V ˙ A / Q ˙ matching with three broad classes of techniques: (i) those based in gas exchange, such as the multiple inert gas elimination technique (MIGET); (ii) those derived from imaging techniques such as single-photon emission computed tomography (SPECT), positron emission tomography (PET), magnetic resonance imaging (MRI), computed tomography (CT), and electrical impedance tomography (EIT); and (iii) fluorescent and radiolabeled microspheres. The focus is on the physiological basis of these techniques that provide quantitative information for research purposes rather than q...

Objectives Radical chemotherapy-radiotherapy represents the standard treatment for locally-advanced nonsmall cell lung cancer (NSCLC). Conventional radiotherapy achieves limited local tumor control, but dose escalation to the primary tumor is prevented by radiotherapy-induced toxicity. The aim of this study was to evaluate feasibility of tailored intensity-modulated radiotherapy (IMRT) planning based on lung single-photon emission computed tomography (SPECT) perfusion data and to compare functional and conventional dose-volume parameters. Methods A total of 21 patients were prospectively enrolled. Patients underwent I...

Conclusion: The acquisition protocol of SPECT being semicircular orbit needs careful selection of arc by keeping the patient position as 'feet first supine' for various types of dextrocardia. The processing and reconstruction of data by changing patient position to prone was found to be most useful method to match the septal and lateral wall orientation for interpretation of images.
