Technical notes for "Cavernoma (Cavernous Malformation) MRI Protocol"
Post contrast T1-weighted transverse:Although cavernomas may exhibit enhancement, we will be looking mainly for other enhancement related lesions such as venous angiomas or hemorrhagic tumors. Some of these other lesions may not be appreciated on noncontrast examinations.
Gradient echo sequences are the most sensitive sequences for cavernomas. This makes them the preferred sequence for locating cavernomas in patients who tend to have multiple lesions.
