Nonlocal low-rank and sparse matrix decomposition for low-dose cerebral perfusion CT image restoration
CONCLUSION: The proposed method can effectively suppress noises in low-dose cerebral perfusion CT images to obtain accurate cerebral hemodynamic parameters.PMID:36210703 | PMC:PMC9550540 | DOI:10.12122/j.issn.1673-4254.2022.09.06

Spontaneous coronary artery dissection and acute myocardial infarction in women
Proc (Bayl Univ Med Cent). 2022 Jul 13;35(6):824-826. doi: 10.1080/08998280.2022.2094652. eCollection 2022.ABSTRACTSpontaneous coronary artery dissection (SCAD) is increasingly recognized as a cause of acute coronary syndrome, acute myocardial infarction, and sudden death in young patients, particularly women, presenting to the emergency department with chest pain. It is the most common cause of nonatherosclerotic coronary artery disease in women <50 years of age. Current guidelines for SCAD management come from case series that have demonstrated low success rates and high rates of complications with percutaneous corona...

Usefulness of non-gated chest computed tomography scans in the diagnosis of acute myocardial infarction
Proc (Bayl Univ Med Cent). 2022 Aug 12;35(6):827-829. doi: 10.1080/08998280.2022.2106416. eCollection 2022.ABSTRACTContrast-enhanced computed tomography (CT) is frequently utilized to evaluate patients who present to the emergency department with chest pain for a pulmonary or aortic disease but is not routinely used to evaluate for acute myocardial infarction (AMI). Decreased myocardial enhancement in non-electrocardiogram-gated contrast-enhanced CT has been proposed to indicate AMI. These two cases highlight the importance of carefully evaluating the myocardium for perfusion defects on non-gated chest CT scans in patients...
