The clinical benefit of high-resolution 3D proton density at 3T
in the discrimination between intracranial aneurysm and normal
variants

1Diagnostic Imaging, Monash Health, Melbourne, Australia At 3T, a three-dimensional proton density (3D PD) weighted sequence plays a supplementary role to the time-of-flight MR angiography (TOF MRA) to improve diagnosis and significantly decreases indeterminate findings for aneurysm. This leads to better patient care and a measurable decrease in the likelihood for the patient to undergo surveillance or more invasive tests that use ionising radiation and intravenous contrast media like Computed Tomography Angiography (CTA) and Digital Subtraction Angiography (DSA). The anxiety and stress that patients experience due to inconclusive findings and ongoing surveillance has been significantly alleviated since the inclusion of the 3D PD to the protocol. |

Comparison of compressed sensing accelerated MR elastography to
standard breath-hold gradient recalled echo MRE for estimating
liver stiffness

The standard MRE(sMRE) uses four breath-hold, each of 14–22
s, to stage liver fibrosis. The long breath-hold time
challenges most children and adult patients with limited
breath-hold capability. The compressed sensing (CS)
technique was used to accelerate the MRE (csMRE) acquisition
to shorten the breath-hold duration (~10s). The preliminary
results showed that the LS estimated from csMRE strongly
correlated to sMRE and showed strong agreement in the normal
to mild liver fibrosis stage. However, it underestimates the
liver stiffness in the elevated liver stiffness. The
confident available area for LS estimation in csMRE
increased 38% compared to sMRE.

Our purpose was to evaluate the correlations between right
ventricular (RV) late gadolinium enhancement (LGE) at
cardiac magnetic resonance (CMR) in patients with Tetralogy
of Fallot (ToF) scheduled for pulmonary valve replacement
(PVR) and post-PVR functional data. After assessing a
semiquantitative LGE scoring for the RV, we observed a
correlation between such score and RV post-PVR outcomes
appraised at CMR. The assessment of RV LGE before PVR may
provide prognostic insights on post-PVR functional outcomes,
potentially facilitating a patient-tailored treatment
pathway.
