Does nonlinear myocardial signal intensity correction improve quantification of contrast-enhanced first-pass MR perfusion in humans?
The nonlinearity between signal intensity and myocardial contrast concentration in perfusion MRI can be corrected through magnetization modeling. A nonlinear correction of myocardial signal intensity is feasible and improves quantitative perfusion analysis.
Overall, a greater prevalence of MAD 20 alleles and increased serum TNF-α and CXCL9 levels were associated with severe outcome in malaria. Understanding the diversity of malaria genotypes is important for predicting disease-related outcomes of P. falciparum infection in endemic areas.
