background: cardiac risk assessment with myocardial perfusion imaging (mpi) is a common practice for some elderly breast cancer patients who are candidates for operation. in rare cases the tumor may become visible in the images. case presentation: this is the report of a case with a huge slow-growing breast tumor suspicious for malignancy and presenting with methoxy-isobutyl-isonitrile (mibi) u...

INTRODUCTION The product of heart rate and systolic blood pressure, termed as rate-pressure product (RPP), is a very reliable indicator of myocardial oxygen demand and is widely used clinically. There have been previous attempts to describe the relationship between RPP and the onset of pain in angina pectoris. The current study aimed to evaluate the association between RPP results and scan find...

It has been quite some time since a new myocardial perfusion agent for radionuclide imaging was introduced into clinical practice. For more than 30 years, rest and stress myocardial perfusion imaging (MPI), employing first planar and then single photon emission computed tomography (SPECT) technology, have been performed with thallium201, Tc-99m sestamibi and Tc-99m tetrofosmin. MPI with these a...

OBJECTIVE MPI can provide valuable information in the investigation of patients with known or suspected coronary artery disease. The stress component of the studies can be conducted with regadenoson, which was approved for clinical use in Greece in 2016. We investigated the performance and safety profile of regadenoson MPI based on our 7 months institutional experience. PATIENTS AND METHODS W...

Abstract Funding Acknowledgements Type of funding sources: None. Background Myocardial perfusion imaging (MPI) by 15O-H2O positron emission tomography (PET) has excellent diagnostic accuracy for detecting significant coronary stenoses and consequently revascularization in patients with angina no previous artery disease (CAD). However, arrhythmias such as atrial fibrillation (AF) are thought to ...

BACKGROUND Adenosine is commonly used for pharmacologic stress myocardial perfusion imaging (MPI). However, it frequently results in adverse effects, and the subdiaphragmatic tracer uptake may interfere with the image interpretation. Our aim was to determine the feasibility of combining low-level treadmill exercise with adenosine MPI and its impact on adverse effects, image quality, and myocard...

background: pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. the aim of this study was to evaluate whether spect/ct myocardial perfusion imaging (mpi) could be used for assessing sheep myocardium following an acute myocardial infarction (mi) and response to int...

Abstract Background Computed Tomography Coronary Angiography (CTCA) is an effective non-invasive imaging modality for anatomo-functional assessment of coronary artery disease (CAD). Radiomics features have been used diagnosis or outcome prediction, however, their potential value characterizing flow limiting lesions has not explored. Purpose To assess whether application novel radiomics and mach...
