BACKGROUND The American Society of Nuclear Cardiology and the Society of Nuclear Medicine conclude that incorporation of attenuation corrected (AC) images in myocardial perfusion scintigraphy (MPS) will improve diagnostic accuracy. The aim was to investigate the value of adding AC stress-only images for the decision whether a rest study is necessary or not. METHODS 1,261 patients admitted to ...

Introduction: Differentiating between ischemic cardiomyopathy (ICM) and idiopathic dilated cardiomyopathy (IDCM) is important as coronary revascularization can improve prognosis in the ischemic subgroup. Due to inherent problems of coronary angiography in patients with depressed ejection fraction (EF) introducing a noninvasive tool to diagnose those who will benefit from angiography seems...

BACKGROUND AND PURPOSE MR perfusion imaging can be used to help predict glial tumor grade and disease progression. Our purpose was to evaluate whether perfusion imaging has a diagnostic or therapeutic impact on clinical management planning in patients with glioma. MATERIALS AND METHODS Standard MR imaging protocols were interpreted by a group of 3 NRs in consensus, with each case being interp...

Antianginal and lipid-lowering medications may modify the results of stress myocardial perfusion imaging. Several studies have shown the beneficial potential of these agents in suppressing myocardial ischemia in patients with known coronary artery disease. The effects of nitrates, calcium-channel blockers, beta-blockers, and statins on myocardial perfusion imaging are likely attributable to cha...

This talk will shed some first light on the two imaging concepts diffusion weighted imaging (DWI) and perfusion weighted imaging (PWI). On the one side one may criticize that for the lecture time given, this will definitely be an incredible or even impossible task: To give sufficient credit to both of these importantant imaging concepts. On the other side one could say: ’Come on, let’s talk abo...

Brain single-photon emission computerized tomography (SPECT), in particular, with perfusion agents or with neuroreceptor imaging radiopharmaceuticals, is rapidly becoming a clinical tool in many neurologic and psychiatric conditions. This imaging modality has been used for diagnosis, prognosis assessment, evaluation of response to therapy, risk stratification, detection of benign vs. malignant ...

Computed tomography (CT) is capable of comprehensively assessing the heart in order to provide information on anatomy, function, perfusion and viability. CT coronary angiography can assess both the coronary artery lumen and the characteristics of atherosclerotic plaques. CT myocardial perfusion imaging can provide additional information compared to CT coronary angiography by highlighting areas ...

BACKGROUND MRI differentiation between metastases and high grade gliomas is a challenging task. Contrast enhancement and size of edema do not provide clear-cut differentiators. The differences in the properties of the peritumoral edema between these tumor types may be exploited to distinguish between them, using MRI perfusion sequences, which are capable of imaging edema in the clinical setting...

Myocardial Perfusion Imaging (MPI) is a non-invasive modality with proven diagnostic and prognostic utility in coronary artery disease. We present case of Transthyretin Amyloid Cardiomyopathy (ATTR-CM) where MPI findings were vastly different from Transthoracic Echocardiogram (TTE) Cardiac Magnetic Resonance (CMR). A 78-year-old gentleman presented atypical chest pain to rule out ischemic heart...
