Abstract: Cardiac involvement is the leading cause of death in patients with cardiac amyloidosis. Early recognition
is crucial as it can significantly change the course of the disease. Until now, the imaging modality of
choice for diagnosing cardiac amyloidosis has been cardiac magnetic resonance imaging (CMR) with late gadolinium
enhancement (LGE). LGE-CMR in patients with cardiac amyloidosis reveals characteristic LGE patterns
that lead to a diagnosis while also correlating well with disease prognosis. However, LGE-CMR has numerous
drawbacks that the newer CMR modality, T1 mapping, aims to improve. T1 mapping can be further
subdivided into native T1 mapping, which does not require the use of contrast, and ECV measurement, which
requires the use of contrast. Numerous T1 mapping techniques have been developed, each one with its own advantages
and disadvantages when it comes to procedure difficulty and image quality. A literature review to identify
relevant published articles was performed by two authors. This review aimed to present the value of T1
mapping in diagnosing cardiac amyloidosis, quantifying the amyloid burden, and evaluating the prognosis of patients
with amyloidosis with cardiac involvement.
