| description | Various sequences have been developed for MRI to aid in the radiologic diagnosis. Among the
various MR sequences, susceptibility-weighted imaging (SWI) is a high-spatial-resolution, threedimensional
gradient-echo MR sequence, which is very sensitive in detecting deoxyhemoglobin,
ferritin, hemosiderin, and bone minerals through local magnetic field distortion. In this regard,
SWI has been used for the diagnosis and treatment of various neurologic disorders, and
the improved image quality has enabled to acquire more useful information for radiologists.
Here, we explain the principle of various signals on SWI arising in neurological disorders and
provide a retrospective review of many cases of clinically or pathologically proven disease or
components with distinctive imaging features of various neurological diseases. Additionally,
we outline a short and condensed overview of principles of SWI in relation to neurological disorders
and describe various cases with characteristic imaging features on SWI. There are many
different types diseases involving the brain parenchyma, and they have distinct SWI features.
SWI is an effective imaging tool that provides complementary information for the diagnosis
of various diseases. |
