Volume measurements in nuclear medicine gated SPECT and 4D echocardiography: validation using a dynamic cardiac phantom

SummaryThe working group Cardiovascular Nuclear Medicine of the German Society of Nuclear Medicine (DGN), in cooperation with the working group Nuclear Cardiology of the German Cardiac Society (DGK), decided to conduct a national survey on myocardial perfusion scintigraphy (MPS). Method: A questionnaire to evaluate MPS for the year 2005 was sent. Results: 346 completed questionnaires had been returned (213 private practices, 99 hospitals and 33 university hospitals). MPS of 112 707 patients were reported with 110 747 stress and 95 878 rest studies. The majority (>75%) was performed with 99mTc-MIBI or tetrofosmin. 201Tl stress-redistribution was used in 22 637 patients (20%). The types of stress were exercise in 78%, vasodilation with adenosine or dipyridamol in 21% and dobutamine in 1%. 99.97% of all MPS were SPECT studies. Gated SPECT was performed in 36% of the stress and in 32% of the rest studies. An attenuation correction was used in 21%. 29 institutions (8%) performed gated SPECT (stress and rest) and attenuation correction. 47% of all MPS were requested by ambulatory care cardiologists, 17% by internists, 12% by primary care physicians, 21% by hospital departments and 2% by others. Conclusion: In Germany, MPS is predominantly performed with 99mTc-perfusion agents. The common type of stress is ergometry. Gated SPECT and attenuation correction do not yet represent standards of MPS practice in Germany, which indicates some potential of optimization.

The Impact

Objective: Gated SPECT myocardial perfusion imaging (GSMPI) is a preferred modality for non invasive assessment following coronary revascularization (CR) of both symptomatic and asymptomatic patients. This study was conducted to observe the impact of GSMPI results on further management of patients who after CR had underwent GSMPI at National Institute of Nuclear Medicine and Allied Sciences (NINMAS). Patients and methods: Record files of GSMPI of all patients who underwent GSMPI over a period of 31 months from June 2011 to December 2013 at NINMAS for assessment of perfusion after CR were selected from the Nuclear Cardiology Divisional archive of patient studies in order to retrieve their clinical and demographic data including the contact numbers. The results of GSMPI scan were categorized as normal scan (NS) and perfusion defect (PD) which included reversible and/or fixed PD. All the contact numbers were called up by a nuclear medicine physician who conducted a semi-structured telephonic interview either with the patients or with a concerned family member. Management strategies adopted after GSMPI were categorized as conservative (CM) and interventional (IM).Cramer’s V (φc) test were done to find strength of relation among patients’ symptoms, scan findings and management strategies. Results: Follow up data of 55 patients (54M, 1F) among 68 (66M, 2F) were available who underwent MPI for the purpose of post CR assessment. MPI was performed in between six months to 13 years after CR (mean 43.8 ± 48.2 months). Categorically 33 patients had percutaneous transluminal coronary angioplasty (PTCA) with stent, 16 patients had coronary artery by-pass grafting (CABG) and 6 patients had both CABG & PTCA. There were 38PD (27symptomatic) and 17NS(12 symptomatic).Since all patients (n=12) who had fixed PD were symptomatic, a strong relation was found between being symptomatic and fixed perfusion defect (φc> 0.3). Symptoms were found to be weakly related with reversible PD i.e. ischemia (φc< 0.2). Management strategies were conservative in 44 (30 symptomatic and 28 PD) and interventional in 11 (nine symptomatic and 10 PD). Management strategies were found to be weakly related with symptoms (φc< 0.2) but moderately related with perfusion status (φc = 0.24). Conclusions: While symptoms were observed to be poorly related with perfusion status following CR, GSMPI guided to choose further interventional management strategies with rationality in lower proportion of patients.

Patient Radiation Exposure

Summary Aim: The working group Cardiovascular Nuclear Medicine of the German Society of Nuclear Medicine in cooperation with the working group Nuclear Cardiology of the German Cardiac Society herewith present the results of the 4th survey on myocardial perfusion scintigraphy (MPS) of the year 2008. Method: 310 questionnaires (191 private practices (PP), 93 hospitals (HO), 31 university hospitals (UH)) were evaluated. Results: MPS of 98 947 patients were reported. 15% of them were younger than 50 y, 57% between 50 and 70 y and 28% older than 70 y. 88% [2007: 83%] of all were studied with Tc-99m perfusion tracers. The patient radiation exposure of a stress and rest protocol considering German standard recommended doses was 8.5 mSv, of a stress-only protocol 1.9 mSv. 77% [2007: 76%] of the MPS were performed in PP, 15% [2007: 15%] in HO and 8% [2007: 9%] in UH. From 2005 to 2008 there was a mild increase in the MPS numbers by 1.2% (PP +7.1%, HO −5.5%, UH −31.4%). The type of stress was pharmacological in 30% [2007: 27%]; 68% adenosine (of these 22% with exercise), 29% dipyridamole (of these 64% with exercise), and <1% dobutamine. Gated SPECT was performed in 46% [2007: 47%] of all rest and in 42% [2007: 44%] of all stress MPS. 62% [2007: 61%] of all institutions did not use perfusion scores. Conclusion: The MPS numbers from 2005 to 2008 in Germany can be regarded as stable. However, there are considerable shifts from HO and UH to PP. The well known potential of MPS considering risk stratification and functional analysis has not been tapped so far. Both gated SPECT and a quantitative perfusion analysis should be performed routinely in every patient.
