Selection of abstracts from the scientific sessions of The Society Of Nuclear Medicine and Molecular Imaging annual meeting Anaheim CA

AbstractThis mini-review highlights cardiovascular studies that were presented during the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2019 annual meeting in Anaheim, California. The aim is to provide the readers insight to noteworthy studies related to the fields of nuclear cardiology presented during the conference. Although cardiovascular applications of positron emission tomography (PET) and single-photon emission computed tomography (SPECT) are not the primary focus of the SNMMI, several scientific teams working in this field presented their latest findings in Anaheim. While this review is directed to the benefit of those who were not able to attend the annual meeting, we believe that a general overview may also be useful for those who did attend as it is often difficult to get exposure to all the high-quality abstracts presented at this large conference.

This article begins by providing an overview of the MMP subfamily and its structure and function. The latest advances in the design of subtype selective MMPIs and their biological evaluation are then summarized. Subsequently, the potential use of MMPI-labeled diagnostic agents in clinical imaging techniques are discussed, including positron emission tomography (PET), single-photon emission computed tomography (SPECT) and optical imaging (OI). Finally, this article concludes with future perspectives and clinical utility.

ConclusionsDue to the relatively high prevalence of abnormal stress MPI, tailored protocols with a stress-first MPI as well as the use of 2-day protocols and advanced imaging technologies including CZT SPECT, novel image reconstruction software, and PET MPI could substantially reduce radiation dose in complex CHD.

We report 2 cases of drug induced Parkinsonism followed longitudinally that remained symptomatic 22 and 27 months after stopping causative agents with normal dopamine ioflupane iodine-123 (DaT) single-photon emission computed tomography (SPECT) scans at 8 and 16 months.

Authors: Nishida H, Hayashi Y, Ban Y, Kudo T, Harada N, Sakurai T Abstract A 61-year-old dextral woman was admitted to the hospital with difficulty finding words. Neurological examinations confirmed that her speech was affected by frequent pauses and occasional phonological paraphasia without cognitive deficits. We detected atrophy, hypoperfusion, and hypometabolism in the right perisylvian and parietal regions, expanding to the right anterior temporal lobes and right inferior frontal gyrus (opercular region) by magnetic resonance imaging, single-photon emission computed tomography, and fluorodexyglucose-positron e...

Nuclear medicine relies on two imaging modalities to assess internal function and diagnose disease. Positron emission tomography (PET) typically uses fluorine-18, a radiotracer that releases positrons, and a special scanner to detect the resulting ga...

Publication date: Available online 1 August 2019Source: Inorganica Chimica ActaAuthor(s): F. Cortezon-Tamarit, A. Baryzewska, M. Lledos, S.I. PascuAbstractIn recent years, the use of metallic isotopes for nuclear imaging techniques such as single photon emission computed tomography (SPECT) and positron emission tomography (PET) has become an area of much interest. In particular, PET is a molecular imaging modality that relies on the detection of two antiparallel, co-linear gamma rays (511 keV) emitted when a positron undergoes annihilation with an electron. PET isotopes of interest in medical practice are numerous and thei...

CONCLUSION: Functional lung avoidance planning may promote increased post-treatment perfusion in low dose regions for select patients, though inter-patient variability remains high in unbalanced cohorts. These preliminary findings form testable hypotheses that warrant subsequent validation in larger cohorts within randomised or case-matched control investigations. ADVANCES IN KNOWLEDGE: This novel preliminary study reports differences in dose-response relationships between patients receiving functional lung avoidance radiation therapy (FLARE-RT) and those receiving conventionally planned radiation therapy (LUNG-RT). F...

ConclusionSince the European Association of Nuclear Medicine 2012 guidelines, the excellent results obtained with gallium-68 (68Ga)-labelled somatostatin analogues (SSAs) in recent years have simplified the imaging approach for PPGL patients that can also be used for selecting patients for peptide receptor radionuclide therapy as a potential alternative or complement to the traditional theranostic approach with iodine-123 (123I)/iodine-131 (131I)-labelled meta-iodobenzylguanidine. Genomic characterisation of subgroups with differing risk of lesion development and subsequent metastatic spread is refining the use of molecula...

AbstractPurpose of ReviewThe purpose of this article is to review the imaging findings and current imaging techniques of acute pulmonary embolism (PE) and chronic thromboembolic disease. Special considerations are also discussed, including pregnancy, congenital heart disease, lower extremity computed tomography (CT), and the isolated subsegmental PE.Recent FindingsCT pulmonary angiography and planar ventilation/perfusion (V/Q) lung scintigraphy are the primary means of evaluating pulmonary embolic disease. Magnetic resonance angiography avoids ionizing radiation and iodinated contrast in select patients. V/Q SPECT/CT provi...

CONCLUSION: The requirements of imaging are determined by clinical presentation, laboratory findings, tumor stage, the presence of a tumor syndrome and the need of a personalized systemic treatment modality. PMID: 31359091 [PubMed - as supplied by publisher]
