Bonjour à toutes et tous, ma question porte sur le terme "Hämosequenz" dans le contexte d'un examen d'IRM. Après une séquence FLAIR, une "Hämosequenz" complémentaire a été réalisée afin de vérifier la présence de résidus d'hémorragie intracrânienne. S'agit-il d'une séquence SWI (plus sensible au sang et aux produits de la dégradation de l'hémoglobine) ? Qu'en pensent les spécialistes ? Merci par avance !

perhaps this is
susceptibility-weighted angiography
in English
This study evaluated the sensitivity of susceptibility-weighted angiography (SWAN) compared with gradient echo (GRE) sequence in the depiction of haemorrhagic and calcium lesions by virtue of correlation analysis between the number, area and contrast index.

SWI Image acquired at 4 Tesla showing the veins in the brain.
Susceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. SWI uses a fully flow compensated, long echo, gradient recalled echo (GRE) pulse sequence to acquire images. This method exploits the susceptibility differences between tissues and uses the phase image to detect these differences. The magnitude and phase data are combined to produce an enhanced contrast magnitude image. The imaging of venous blood with SWI is a blood-oxygen-level dependent (BOLD) technique which is why it was (and is sometimes still) referred to as BOLD venography. Due to its sensitivity to venous blood SWI is commonly used in traumatic brain injuries (TBI) and for high resolution brain venographies but has many other clinical applications. SWI is offered as a clinical package by Philips and Siemens but can be run on any manufacturer’s machine at field strengths of 1.0 T, 1.5 T, 3.0 T and higher.
