Abstract:

Perfusion scintigraphy with the acquisition of planar blood flow and pool images of bilateral hands has been used to aid diagnosis and to evaluate treatment response to Raynaud’s phenomenon (decreased blood flow to hand or foot). However, because of the difficulty in imaging the tongue area with a conventional gamma camera, perfusion scintigraphy imaging of patients with lingual Raynaud’s phenomenon has yet to be reported. Here, we report the case of a 59-year-old man with lingual Raynaud’s phenomenon in which blood pool imaging of the tongue was performed using three-dimensional (3D)-ring cad

Abstract:

Dementia with Lewy bodies (DLB) can be diagnosed through a combination of clinical criteria, the loss of dopaminergic neuron terminals in presynaptic [123I]FP-CIT SPECT dopaminergic imaging, and diffuse [18F]FDG PET hypometabolism, which typically affects also the visual cortex. A 360-degree CZT SPECT systems offer advantages in terms of count sensitivity, and both contrast and energy resolution for perfusion and dopaminergic imaging as compared with conventional SPECT systems. As it happens for PET imaging protocols, a dual-time-window protocol with CZT SPECT imaging was used for a suspected

Abstract Background The aim of this study was to investigate the quantification performance of a 360° CZT camera for 177Lu-based treatment monitoring. Methods Three phantoms with known 177Lu activity concentrations were acquired: (1) a uniform cylindrical phantom for calibration, (2) a NEMA IEC body phantom for analysis of different-sized spheres to optimise quantification parameters and (3) a phantom containing two large vials simulating organs at risk for tests. Four sets of reconstruction parameters were tested: (1) Scatter, (2) Scatter and Point Spread Function Recovery (PSFR), (3) PSFR on

Abstract Purpose For the first time, three currently available 360° CZT-SPECT/CT cameras were compared under clinical conditions using phantom-based measurements. Methods A 99mTc- and a 177Lu-customized NEMA IEC body phantom were imaged with three different cameras, StarGuide (GE Healthcare), VERITON-CT versions 200 (V200) and 400 (V400) (Spectrum Dynamics Medical) under the same clinical conditions. Energy resolution and volumetric sensitivity were evaluated from energy spectra. Vendors provided the best reconstruction parameters dedicated to visualization and/or quantification, based on thei

Abstract Aim/Introduction The diagnostic accuracy of myocardial perfusion scintigraphy (MPS) for detecting coronary artery diseases (CAD) is improved when using attenuation-corrected (AC) images. However, for economic reasons, most clinical cardiac-dedicated CZT cameras are marketed without a CT. Therefore, the CASCTEC clinical study aims at developing an approach to generate AC images only from emission scans on a pinhole CZT camera, without the need for CT. Materials & Methods Up to now 25 patients referred for MPS have been enrolled in the CASCTEC single-center prospective study. Two-da

Abstract Funding Acknowledgements Type of funding sources: None. Background. Myocardial infarction with non-obstructive coronary arteries (MINOCA) is currently of interest in terms of diagnostic and treatment strategy. The diagnosis of MINOCA has been included in the STEMI guidelines of the European Society of Cardiology. However, there is lack of data regarding the relationship between myocardial damage according to cardiac magnetic resonance (CMR) and myocardial blood flow (MBF), myocardial flow reserve (MFR) obtained by dynamic SPECT. Purpose. To elucidate impairment of myocardial perfusion

Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) is currently of interest in terms of a small amount of data related to myocardial perfusion, myocardial blood flow (MBF) and myocardial flow reserve (MFR). Purpose. To assess the severity of myocardial perfusion, MBF and MFR impairment in MINOCA patients in comparison to those with MI with obstructive coronary artery disease (MICAD) and non-obstructive stable coronary artery disease (SCAD).

Abstract Aim To show the improvement in myocardial perfusion SPECT studies achieved in the year 2023 using a cardio-dedicated CZT gamma camera, compared to year 2021 when using an analogical SPECT/CT gamma camera. Methods We have collected data on nuclear cardiology care activity for the years 2021, 2022 and 2023, including patients treated in our institution. In 2021 myocardial perfusion imaging (MPI) studies were performed primarily on an analogical SPECT/CT gamma camera, which was replaced by a cardio-dedicated CZT in 2022. In 2023 MPI was carried out mainly in the new CZT gamma camera. For
