Abstract
A method for differentiation of normal myocardium from diffuse disease using T mapping includes acquiring one or more images of a patient by an imaging apparatus, generating a T1 map from the one or more images, defining a region of interest within the one or more images, determining the average T1 value within the region of interest, comparing the average T1 value within the region of interest to a cut-off T1 value, and determining a diagnosis of the region of interest from the comparison.
Claims16
A magnetic resonance system comprising:
- a magnetic resonance imaging apparatus;
- and
- one or more processors programmed to:
- receive one or more images of a heart of a patient acquired by the magnetic resonance imaging apparatus;
- generate a T1 map from the one or more images;
- define a region of interest within the one or more images;
- determine the average T1 value within the region of interest;
- compare the average T1 value within the region of interest to a cut-off T1 value;
- and
- determine a hypertrophic cardiomyopathy (HCM) or non-ischemic dilated cardiomyopathy (DCM) diagnosis of the region of interest from the comparison;
- wherein the one or more images of the heart of the patient are acquired only without contrast agent and the generated T1 map is a native T1 map.
A magnetic resonance system, comprising:
- an imaging apparatus which acquires one or more images of a patient without contrast agent present;
- a T1 mapping processor which generates a native T1 map from the one or more images;
- and
- a T1 value processor which defines a region of interest within the one or more images, determines the average T1 value within the region of interest, compares the average T1 value within the region of interest to a cut-off T1 value, and provides a diagnosis based on the comparison;
- wherein a diagnosis for an average T1 value below the cut-off T1 value is healthy.
A method for differentiation of normal myocardium from diffuse disease using T1 mapping, the method comprising, with at least one electronic processor:
- acquiring one or more magnetic resonance signals from a patient without contrast agent using a magnetic resonance imaging apparatus;
- reconstructing the received MR signals into one or more images of a patient;
- generating a native T1 map without contrast from a contrast agent from the one or more images;
- defining a region of interest within the one or more images;
- determining the average T1 value within the region of interest;
- comparing the average T1 value within the region of interest to a cut-off T1 value;
- and
- determining a diagnosis of the region of interest from the comparison, wherein the diagnosis for an average T1 value above the cut-off T1 value is hypertrophic cardiomyopathy (HCM) or non-ischemic dilated cardiomyopathy (DCM) disease and the diagnosis for an average T1 value below the cut-off T1 value is healthy.
