Publication date: November–December 2017 Source:Revista Española de Medicina Nuclear e Imagen Molecular (English Edition), Volume 36, Issue 6 Author(s): T. Massardo, L. Alarcón, J. Spuler A discussion is presented on the current use of radionuclides for evaluation of coronary artery disease in relation to other available techniques. The review is focused on coronary artery disease risk stratification employing single photon emission computed tomography and positron emission tomography, as well as on ischemic cardiomyopathy and myocardial viability applications. Concepts are presented regarding coronary...

García-Concha, S. Arevalo-Leal Vascular graft infections are a rare complication in this type of procedure. However, when they do occur, they usually have high morbidity, and even a high mortality. Proper identification and location is crucial for the appropriate and early management, whether medical or surgical, thus knowledge of the right tools is paramount. Nuclear medicine studies play an important r...

Authors: Nakaya K, Onoguchi M, Nishimua Y, Kiso K, Otsuka H, Nouno Y, Shibutani T, Yasuda E Abstract Background: Prone single photon emission computed tomography (SPECT) is suitable for evaluating the cardiac inferior wall as it suppresses attenuation artifacts from the diaphragm. The solid-state dedicated cardiac camera (D-SPECT) allows upright imaging, which can also be used to avoid attenuation artifacts from the diaphragm. We compared prone and upright imaging for inferior wall evaluation using (201)TlCl myocardial perfusion SPECT. Methods: The study targeted 45 patients. The prone imaging group included 23 sub...

Conclusion: All the absorbed doses were comparable to those known for most of the 99mTc studies. 99mTc-exendin(9-39)/octreotide obtained from kit formulations showed high tumor uptake in a patient with a malignant lesion, making it a promising imaging radiopharmaceutical to target GLP-1R and SSTR.

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.

AbstractThe current study is aimed to prepare99mTc-lidocaine as a new myocardial perfusion-imaging agent. The used99mTc was obtained from Al –99Mo-molybdate(VI) gel matrix.99mTc-lidocaine showed higher (15.4  ± 0.11% ID/g) and faster (15 min post injection) cardiac uptake than the recently studied99mTc-valsartan and99mTc-procainamide. Consequently,99mTc-lidocaine will be a valuable myocardial SPECT agent for diagnosis of emergency patients. Besides, the receptor affinity study confirmed the selectivity of99mTc-lidocaine for sodium channels in the heart.

This article reviews the key contribution of integrated bone SPECT/CT in evaluating patients with persistent or recurring pain after spinal surgery, focusing on spinal fusion. Current literature supports the use of bone SPECT/CT as an adjunct imaging modality and problem-solving tool in evaluating patients with suspicion of pseudarthrosis, adjacent segment degeneration, and hardware failure. The role of bone SPECT/CT in post-operative orthopaedic scenarios is evolving, and this review highlights the need for further research on the role of bone SPECT/CT in these patients.

ConclusionsAstonishTM requires the adoption of the own specific normal databases in order to prevent very high overestimation of both stress and rest perfusion scores. Conversely, the count statistics of the normal databases seems not to influence the quantification scores.

AbstractBackgroundAdenosine or regadenoson are often used with pharmacologic stress testing. Adenosine may trigger atrioventricular block (AVB). Despite its higher selectivity, regadenoson has also been associated with AVB. We studied the incidence of de novo AVB with these agents.MethodsA comprehensive search of SCOPUS was performed from inception to March 2016. Studies of at least 10 patients, using adenosine and/or regadenoson with SPECT-MPI, reporting rates of AVB were selected for further review.ResultsThirty four studies were pooled including 22,957 patients. Adenosine was used in 21 studies and regadenoson in 15. Bo...

AbstractPurposeOur aim was to determine the utility of Tc-99m-diethylenetriaminepentaacetic acid-galactosyl human serum albumin single-photon-emission computed tomography (99mTc-GSA SPECT/CT) fusion imaging for detecting incomplete portal vein embolization (PVE).Materials and methodsFifty-five candidates underwent PVE. Among them, five underwent second PVE. Detectability of first inadequate PVE using CT and99mTc-GSA SPECT/CT fusion imaging was analyzed.ResultsCases of inadequate PVE were detected in three patients using CT and in five using99mTc-GSA SPECT/CT fusion imaging. Fusion imaging detected two cases of insufficient...
