Abstract

OBJECTIVE. The purpose of this article is to illustrate the utility of susceptibility-weighted imaging (SWI) as an adjunct to routine MRI of the brain in neurologic disorders. CONCLUSION. SWI is a 3D spoiled gradient-echo sequence that combines phase and magnitude information to provide a high sensitivity for the detection of blood degradation products, calcifications, and iron deposits.

Intracranial Lesion Detection and Artifact Characterization: Comparative Study of Susceptibility and T2*-Weighted Imaging in Dogs and Cats

Nadja Wolfer, Adriano Wang-Leandro, Katrin M. Beckmann, Henning Richter, Matthias Dennler

Summary: SWI is more effective than T2*WI in detecting ASV in dogs, with the ability to differentiate between hemorrhagic and calcified lesions. Frontal sinus conformation can impact image interpretation, with brachycephalic dogs showing less severe artifacts in both sequences.

Convergent imaging-transcriptomic evidence for disturbed iron homeostasis in Gilles de la Tourette syndrome

Ahmad Seif Kanaan, Dongmei Yu, Riccardo Metere, Andreas Schaefer, Torsten Schlumm, Berkin Bilgic, Alfred Anwandera, Carol A. Mathews, Jeremiah M. Scharf, Kirsten Mueller-Vahl, Harald E. Moeller

Summary: Quantitative susceptibility mapping (QSM) was performed on 28 patients with Gilles de la Tourette syndrome (GTS) and 26 matched controls, revealing significant reductions in brain iron content in GTS patients. Tic severity was negatively associated with striatal susceptibility. Correlations between susceptibility reductions and gene-expression patterns suggest disruptions in iron regulatory mechanisms are involved in GTS pathophysiology.

Haemorrhage and Calcification on Susceptibility-Weighted Imaging A Quick and Reliable Qualitative Technique for Differentiating Lesions with Ambiguous Phase

Kevin L. Tay, Stewart R. Leason, Laughlin C. Dawes, Sophia L. Thomas, Claudia M. Hillenbrand

Summary: This study investigated the validity of qualitative phase assessment on the cranial or caudal margins for distinguishing haemorrhage and calcification in lesions with ambiguous phase on SWI. Results showed that assessment at the cranial or caudal margins achieved a sensitivity of 100% for both haemorrhage and calcification, which was significantly superior to other methods such as dominant phase or in-plane margin assessment.

Susceptibility- weighted imaging in intracranial hemorrhage: not all bleeds are black

Linda bm Weerink, Auke pa Appelman, Reina w Kloet, A. N. O. U. K. van der Hoorn

Summary: To correctly identify intracranial hemorrhage (ICH) and distinguish it from other lesions, it is necessary to understand the imaging characteristics of ICH on susceptibility weighted imaging (SWI). It is a common misconception that blood appears as a black signal on SWI, but the appearance of ICH on SWI varies at different stages. Additionally, a low signal on SWI does not always indicate the presence of blood products. This review discusses and illustrates the appearance of ICH on SWI at all stages and common causes of a low signal on SWI.

Jinyang Wen, Jinhan Qiao, Yuanyuan Tang, Yun Zhao, Zhaoxia Yang, Luyun Wang, Xinwei Tao, Xiaoyue Zhou, Liming Xia, Lu Huang, Dazhong Tang

Summary: This study evaluated the image quality and diagnostic performance of susceptibility-weighted imaging (SWI) and T1/T2 mapping in detecting reperfusion intramyocardial hemorrhage (IMH) in patients with ST-segment elevation myocardial infarction (STEMI). The results showed that both SWI and T1/T2 mapping had excellent diagnostic performance for detecting IMH, and can be considered as feasible approaches for clinical diagnosis of IMH.

Magnetic Resonance Iron Imaging in Amyotrophic Lateral Sclerosis

Anjan Bhattarai, Gary F. Egan, Paul Talman, Phyllis Chua, Zhaolin Chen

Summary: This review provides an overview of MRI techniques used to investigate iron dysregulation in ALS, highlighting their potential uses and limitations in disease diagnosis and prognosis. It recommends further longitudinal studies to validate the efficacy of these techniques and concludes that quantitative iron assessment using QSM in MRI holds great potential as a sensitive diagnostic and prognostic marker in ALS. Furthermore, combining multimodal neuroimaging markers with iron imaging may offer improved sensitivity in ALS diagnosis and prognosis, contributing significantly to clinical care and treatment trials.

Summary: With the increasing use of high-field MRI in large domestic mammals, techniques developed for human patients can now be applied to study the brain structure and function of these animals. In this study, a optimal GE SWI imaging protocol was designed for dogs undergoing MRI examination of the brain. The protocol was validated using ex vivo brains from four dogs and provided high anatomical detail. This study is the first to provide an anatomical description of SWI images of the canine brain, and once validated in living animals, the protocol could be used to improve the diagnosis of intracranial diseases in dogs or for future comparative studies on brain iron content in animals.

Summary: Myelin is a protective sheath made of phospholipid bilayer and water that wraps around axons. Non-invasive quantitative myelin imaging methods are needed for evaluating myelin damage, assessing the efficacy of remyelination therapies, and monitoring brain maturation in children. Different MRI and PET techniques have been developed for myelin imaging based on various biophysical principles. This review provides an overview of these techniques, including image acquisition, data analysis, and validation status, and concludes that quantitative susceptibility mapping, inhomogeneous magnetization transfer for MRI, and C-11-MeDAS for PET are the most promising techniques.

Clinical and neuroimaging features of a familial pathogenic ACTA2 variant as a model of a vascular neurocristopathy

David Andrew Prentice, Tejinder Singh, Paul Maria Parizel

Summary: This paper discusses the clinical and neuroimaging findings of a family with a variant ACTA2 gene (c351C > G). The disorder is characterized by a combination of aortic abnormalities, patent ductus arteriosus, congenital mydriasis, and distinctive cerebrovascular and brain morphological abnormalities. The report presents two sisters who are heterozygous for the variant and their mother who is a mosaic. It also provides detailed brain parenchymal changes for the first time in a non-Arg179His variant and highlights the radiological features of the petrous canal and external carotid. The potential underlying biological and embryological mechanisms are explored.

The effect of prolonged spaceflight on cerebrospinal fluid and perivascular spaces of astronauts and cosmonauts

Giuseppe Barisano, Farshid Sepehrband, Heather R. Collins, Steven Jillings, Ben Jeurissen, James A. Taylor, Catho Schoenmaekers, Chloe De laet, Ilya Rukavishnikov, Inna Nosikova, Liudmila Litvinova, Alena Rumshiskaya, Jitka Annen, Jan Sijbers, Steven Laureys, Angelique Van Ombergen, Victor Petrovichev, Valentin Sinitsyn, Ekaterina Pechenkova, Alexey Grishin, Peter zu Eulenburg, Meng Lawl, Stefan Sunaert, Paul M. Parizel, Elena Tomilovskaya, Donna R. Roberts, Floris L. Wuyts

Summary: Long-duration spaceflight causes changes in the brain and cerebrospinal fluid compartments, leading to spaceflight-associated neuro-ocular syndrome (SANS). MRI analysis showed increased volume of perivascular spaces (PVS) in basal ganglia and white matter after spaceflight, with more significant changes observed in NASA crew members than Roscosmos crew members. The differences in PVS enlargement may be attributed to various factors, including the use of countermeasures and exercise regimes. NASA astronauts with SANS had larger pre- and postflight PVS volumes compared to unaffected individuals, suggesting a potential link between PVS fluid and SANS.

Summary: Hematopoietic and lymphoid tumors encompass a diverse range of diseases, including lymphomas, multiple myeloma, and leukemias. These diseases have systemic involvement and can present with various clinical symptoms, including acute neurological deficits. Patients with hematologic malignancies are prone to developing acute conditions affecting the nervous system, which can be caused by tumor growth, abnormal coagulation status, or immune-related complications. Understanding the etiology and expected CNS imaging findings in these patients is essential for prompt and accurate diagnosis as well as guiding treatment decisions. In this manuscript, we review the CT and MRI findings related to the disease itself and/or its treatments.
