Spatio-Temporal Modelling of Perfusion Cardiovascular MRI [PDF]

, 2010
Myocardial perfusion MRI provides valuable insight into how coronary artery and microvascular diseases affect myocardial tissue. Stenosis in a coronary vessel leads to reduced maximum blood flow (MBF), but collaterals may secure the blood supply of the ...

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Beam hardening artifact reduction using dual energy computed tomography: implications for myocardial perfusion studies [PDF]

, 2015
Background: Myocardial perfusion computed tomography (CTP) using conventional single energy (SE) imaging is influenced by the presence of beam hardening artifacts (BHA), occasionally resembling perfusion defects and commonly observed at the left ...

Considerations for drug trials in hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.
Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.

Positron Emission Tomography in the Diagnosis and Management of Coronary Artery Disease

Medicina, 2018
Cardiac positron emission tomography (PET) and positron emission tomography/computed tomography (PET/CT) are encouraging precise non-invasive imaging modalities that allow imaging of the cellular function of the heart, while other non-invasive ...

Prognostic role of TAPSE to PASP ratio in outpatients with left ventricular systolic dysfunction

ESC Heart Failure, Volume 12, Issue 2, Page 912-922, April 2025.
Abstract Aims Few data are available regarding the role of tricuspid annulus plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP), a measurement of right ventricular to pulmonary artery coupling, in patients with chronic heart failure and left ventricular systolic dysfunction.

Cardiovascular risk factors and development of nomograms in an Italian cohort of patients with suspected coronary artery disease undergoing SPECT or PET stress myocardial perfusion imaging

Frontiers in Nuclear Medicine
IntroductionSingle-photon emission computed tomography (SPECT) and positron emission tomography (PET) are non-invasive nuclear medicine techniques that can identify areas of abnormal myocardial perfusion. We assessed the prevalence of cardiovascular risk

FDG PET/CT imaging and circulating biomarkers of inflammation in desmoplakin cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1485-1489, April 2025.
Abstract Aims Inflammation has been implicated in the pathogenesis of desmoplakin (DSP) cardiomyopathy, and retrospective studies have described abnormal myocardial fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) findings in symptomatic patients eventually diagnosed with DSP cardiomyopathy.

Dynamic Myocardial CT Perfusion Imaging

, 2019
The few patient studies focusing on dynamic CTMPI for myocardial ischemia detection show promising results. Absolute quantification of perfusion parameters offers great potential, not only in the diagnosis of myocardial ischemia but potentially also in the detection of early signs of reduced myocardial blood flow as well as the diagnosis of ...
