Journal ArticleDOI

Theodoros D. Karamitsos,Stefan K. Piechnik,Sanjay M Banypersad,Marianna Fontana,Ntobeko A.B. Ntusi,Vanessa M Ferreira,Vanessa M Ferreira,Carol J. Whelan,Saul G. Myerson,Matthew D. Robson,Philip N. Hawkins,Stefan Neubauer,James C. Moon +12 more
TL;DR: Noncontrast T1 mapping has high diagnostic accuracy for detecting cardiac AL amyloidosis, correlates well with markers of systolic and diastolic dysfunction, and is potentially more sensitive for detecting early disease than LGE imaging.
Journal ArticleDOI

TL;DR: In this paper , the authors assessed the ability of T cells to react to Omicron spike protein in participants who were vaccinated with Ad26.S or BNT162b2, or unvaccinated convalescent COVID-19 patients.
Journal ArticleDOI
T1 Mapping for the Diagnosis of Acute Myocarditis Using CMR: Comparison to T2-Weighted and Late Gadolinium Enhanced Imaging
Vanessa M Ferreira,Stefan K. Piechnik,Erica Dall'Armellina,Theodoros D. Karamitsos,Jane M. Francis,Ntobeko A.B. Ntusi,Cameron J. Holloway,Robin P. Choudhury,Attila Kardos,Matthew D. Robson,Matthias G. Friedrich,Stefan Neubauer +11 more
TL;DR: Native T1 mapping as a novel criterion for the detection of acute myocarditis showed excellent and superior diagnostic performance compared with T2W-CMR.
Journal ArticleDOI
Normal variation of magnetic resonance T1 relaxation times in the human population at 1.5 T using ShMOLLI
Stefan K. Piechnik,Vanessa M Ferreira,Vanessa M Ferreira,Adam J. Lewandowski,Ntobeko A.B. Ntusi,Rajarshi Banerjee,Cameron J. Holloway,Mark B.M. Hofman,Daniel Sado,Viviana Maestrini,Steven K White,Merzaka Lazdam,Theodoros D. Karamitsos,James C. Moon,Stefan Neubauer,Paul Leeson,Matthew D. Robson +16 more
TL;DR: Native T1-mapping using ShMOLLI generates reproducible and consistent results in normal individuals within 2% of relative changes from the average, well below the effects of most acute forms of myocardial disease.
Journal ArticleDOI
Subclinical myocardial inflammation and diffuse fibrosis are common in systemic sclerosis--a clinical study using myocardial T1-mapping and extracellular volume quantification.
Ntobeko A.B. Ntusi,Stefan K. Piechnik,Jane M. Francis,Vanessa M Ferreira,Aitzaz Bin Sultan Rai,Paul M. Matthews,Paul M. Matthews,Matthew D. Robson,James C. Moon,Paul Wordsworth,Stefan Neubauer,Theodoros D. Karamitsos +11 more
TL;DR: Myocardial abnormalities detected on CMR were associated with impaired strain parameters, as well as disease activity and severity in SSc patients, which inversely correlated with diffuse myocardial fibrosis indices.
