“…The high spatial resolution of SWI and increased contrast of SWI increased the confidence of the radiologists in the diagnosis, especially for the less experienced ones. The SWI demonstrated a substantial to almost complete interobserver agreement for identification of hemorrhagic, ischemic, and the whole lesions, which was consistent with El-Serougy et al [29] study, which revealed an almost perfect agreement for the detection of cerebral microbleed with a k value of 0.84. Potential problems connected to the use of SWI, according to Bosemani et al [30], include pitfalls owing to variations in blood oxygenation levels, blood flow, potential pitfalls related to magnetic field intensity, pitfalls due to misinterpretation of localization on minIP images, and mimickers such as gas.…”

Background This study aimed to assess the added value and current applications of SWI in the diagnosis of pediatric non-neoplastic neurological diseases, including its ability to characterize hemorrhage in various brain lesions and its important role in the evaluation of both arterial as well as venous ischemic brain lesions. Results Forty pediatric patients with a median age of 9 years were included in our prospective study; 23 were males and 17 females. SWI had a significantly higher detection rate than conventional MRI for traumatic brain injury (TBI) lesions, hemorrhagic lesions in acute necrotizing encephalopathy (ANEC), and cavernoma lesions (p = 0.005, p = 0.038, and p = 0.046, respectively). The sensitivity, specificity and accuracy of SWI for the detection of venous ischemic insult was 88.9%, 50%, and 76.9% respectively. SWI was significantly better than the conventional MRI (p = 0.046) for the detection of chronic ischemic brain insults and ischemic lesions with added hemorrhagic components. Conclusion SWI is a technique with reasonable acquisition time that could improve the diagnostic performance of MRI for the evaluation of various pediatric non-neoplastic neurological diseases.
