Purpose: Susceptibility Weighted Imaging (SWI) sequence is a gradient-focused new MR sequence consisting of high resolution, three-dimensional, magnificent and phase images and their combination using the magnetic sensitivities of blood products such as deoxyhemoglobin, intrasellular hemoglobin and hemosiderin and minerals such as iron and calcium. The aim was to reveal the availability of the SWI sequence in the neuroradiology practice and the sensitivity in detection of lesions. Materials and Methods: From April 2010 to May 2011, 70 patients (40 men, 30 women) between the ages of 1-87 were included in the study. All incidents included the SWI sequence in the routine conventional MRG examination with the 1.5 T MR device. The sensitivity of the SWI sequence was calculated. Results: In our study, 18 patients had ischemic cerebral infarction, 7 patients had non-traumatic, 7 patients had traumatic bleeding, 10 patients had vascular malformation, 21 patients had intrakranial mass, 7 patients had neurodegenerative disease-related brain mineral accumulation. The SWI sequence increases the manifestity and visibility of micro-macro bleeding, venous malformations and mineral accumulation compared to conventional sequences. The result: the SWI sequence, micro and macro bleeding, indicating bleeding in the injury, more accurate detection of the limits of the cranic masses, cerebral infarction is also a sensitive new MR imaging sequence in the detection of many pathologies, such as hemorrhagic stage, cellular mineral accumulation.
