Click 62 year old female with aneurysm of the membranous septum (AMS).
Technique: MRI 1,5T; Steady State Free Precession (SSFP) four chambers view; TR (repetition time) 3,6 msec, TE (echo time) 1,6 msec, Flip angle 65, Slice thickness 4mm, Image matrix 256 x 256.
Finding: Steady State Free Precession (SSFP) four chambers view in systole and diastole show an AMS (20 x 15 mm) arising from membranous septum beneath the septal leaflet of the tricuspid valve, bulging into right ventricle, without any thrombus or shunt flow between the ventricles.

Technique: MRI 1,5T; Steady State Free Precession (SSFP) short axis view; TR (repetition time) 3,6 msec, TE (echo time) 1,6 msec, Flip angle 65, Slice thickness 4mm, Image matrix 256 x 256.
Finding: Steady State Free Precession (SSFP) short axis view in systole and diastole show AMS adjacent to interventricular septum, inferior to the aortic valve, protruding in right ventricular chamber.


Click 62 year old female with aneurysm of the membranous septum (AMS).
Technique: MRI 1,5T; myocardial LE (Late Enhancement) short axis view acquired 10 / 15 min following the intravenous administration of contrast medium (BOPTA, MultiHance); TR (repetition time) 3,6 msec, TE (echo time) minimum, TI (Inversion Time) 180 msec, Flip angle 20, Image Matrix 256 x 256.
Finding: myocardial LE (Late Enhancement) short axis view in systole and diastole show AMS without evidence of hyperintensity.
