Stress native T1 and native T2 mapping compared to myocardial perfusion reserve in long-term follow-up of severe Covid-19

Scientific Reports, 2023
Severe Covid-19 may cause a cascade of cardiovascular complications beyond viral pneumonia. The severe inflammation may affect the microcirculation which can be assessed by cardiovascular magnetic resonance (CMR) imaging using quantitative perfusion ...

Rationale and design of the Clinical Evaluation of Magnetic Resonance Imaging in Coronary heart disease 2 trial (CE-MARC 2): a prospective, multicenter, randomized trial of diagnostic strategies in suspected coronary heart disease [PDF]

, 2015
Background: A number of investigative strategies exist for the diagnosis of coronary heart disease (CHD). Despite the widespread availability of noninvasive imaging, invasive angiography is commonly used early in the diagnostic pathway.

Unraveling septal perfusion abnormalities in Ebstein's anomaly: A case report contrasting PET MPI with myocardial reality

Radiology Case Reports
In Ebstein's anomaly, septal perfusion abnormality poses a challenge in traditional interpretations of myocardial blood flow. We report a single case of a 43‐year‐old female with known Ebstein’s anomaly who was referred for preoperative cardiac ...

Perfusion Computed Tomography for the Assessment of Myocardial Viability — a Case Series

Journal of Interdisciplinary Medicine, 2016
Myocardial viability plays an important role in preventing the development of left ventricular remodeling following an acute myocardial infarction. A preserved viability in the infarcted area has been demonstrated to be associated with a lower amplitude ...

A Monte Carlo study of arms effect in myocardial perfusion of normal and abnormal cases utilizing STL heart shape

Results in Physics, 2018
Arms influence in myocardial perfusion single photon emission computed tomography (SPECT) imaging has been studied for the last two decades. These studies suggested that arms positioning next to the patient would not show cardiac abnormalities or ...
