Interstitial expansion in health and disease - an equilibrium contrast CMR study
نویسندگان
چکیده
Methods The three steps in EQ-CMR are: 1) a primed gadolinium infusion to achieve contrast equilibrium, 2) Signal (T1) measurement pre and post equilibrium, 3) measurement of blood contrast volume (1haematocrit). This allows calculation of Vd(m) by: Vd(m) =(1-hematocrit) x Δ(1/T1)myo ÷ Δ(1/T1)blood. Vd(m) was measured in 278 subjects: 86 normal subjects (median age 43, range 24 to 81, 51% male) and 192 patients with Anderson-Fabry disease (AFD, n=17), dilated cardiomyopathy (DCM, n=31), hypertrophic cardiomyopathy (HCM, n=31), severe aortic stenosis (AS, n=66), cardiac amyloidosis (n=27) or myocardial infarction (MI, n=20).

Background Focal fibrosis is visible as late gadolinium enhancement when using inversion recovery (IR) imaging late after a contrast bolus and carries major clinical import. The IR technique results in high sensitivity to regional T1 variation but sacrifices absolute quantification meaning that differing degrees of focal interstitial expansion will look the same (bright). We hypothesized that L...

Background Diffuse myocardial fibrosis (DMF) is an important factor in cardiac disease, but until recently could only be accurately assessed with biopsy. We hypothesised that DMF measured by Equilibrium contrast CMR (EQ-CMR) is elevated in cardiac pressure overload (hypertension and aortic stenosis), that the degree of DMF will track the clinical severity of pressure overload and cardiac effect...
متن کاملDiffuse myocardial fibrosis in the systemic right ventricle of patients late after Mustard or Senning surgery: an equilibrium contrast cardiovascular magnetic resonance study.
AIMS After atrial redirection surgery (Mustard-Senning operations) for transposition of the great arteries (TGA), the systemic right ventricle (RV) suffers from late systolic failure with high morbidity and mortality. Mechanisms of late RV failure are poorly characterized. We hypothesized that diffuse interstitial expansion representing diffuse fibrosis is greater in systemic RVs of patients fo...
متن کاملComparison of T1 mapping techniques for ECV quantification. Histological validation and reproducibility of ShMOLLI versus multibreath-hold T1 quantification equilibrium contrast CMR
BACKGROUND Myocardial extracellular volume (ECV) is elevated in fibrosis or infiltration and can be quantified by measuring the haematocrit with pre and post contrast T1 at sufficient contrast equilibrium. Equilibrium CMR (EQ-CMR), using a bolus-infusion protocol, has been shown to provide robust measurements of ECV using a multibreath-hold T1 pulse sequence. Newer, faster sequences for T1 mapp...

Methods 86 healthy subjects (median age 45, range 24-81, 42 males) were recruited from hospital, university or via a local General Practitioner surgery. All were assessed with a cardiac history and examination, routine blood tests, 12 lead ECG, blood pressure and clinical CMR. Volunteers were excluded if any evidence of cardiovascular disease was found. Baseline differences between male and fem...
