“…[18][19][20] This was observed in previous studies where findings on 3-Tesla MRI was compared to those on 1.5-Tesla MRI. [18,[21][22][23][24] Low-field strength MRI such as the one used for the present study is not able to detect subtle abnormalities like MTS and FCD, but obvious pathologies such as tumours, cerebral ischaemia, congenital malformations and infections can be still diagnosed. This is well demonstrated in the present study.…”

“…Anand, et al [13] recorded a higher percentage of 84% with positive MR images and they were able to detect cortical defects in 13.1% of the children studied. Ahiuwalia, [24] et al recorded abnormal MR findings in 48.1% of cases, of which MTS and FCD accounted for 13.65% and 5.73% respectively. The reason for this high rate of detection of FCD and MTS is no doubt due to the higher field strength (1.5T) used by the previous authors.…”

Background: Seizure is the most common neurological disorder in children and an important cause of paediatric hospital admission with the highest prevalence in the under-five age group. Magnetic Resonance Imaging (MRI) is the neuro-imaging technique of choice in the initial evaluation of children with epilepsy. High-field MRI is the ideal imaging modality for evaluating seizures but this is not readily available in developing countries. Objective: To analyse the spectrum of MRI findings in children presenting with seizures using a low-field (0.36T) MRI. Methods: Children aged ≤18years with seizures, with cranial MRI at the University College Hospital (UCH), Nigeria between January 2013 and June 2015 were retrospectively reviewed. Results: There were a total of 134 patients with 53% as adolescents and most of them (85; 63.4%) had abnormal cranial MRI findings. More male children had abnormal findings (52; 61.2%) and most abnormal findings (42; 49.4%) were reported among adolescents. The most frequent abnormality was hydrocephalus (23.5%) from various causes followed by cerebral tumours (14.1%) and ischaemic cerebral infarcts (11.8%). In the adolescents, intracranial tumours (21.4%) were the most frequent abnormal findings, while hydrocephalus was commoner in children aged less than 10 years, accounting for 33.3% and 36.0% among the 1-5 years and 6-11 years age groups respectively. Conclusion: Low-field MRI, which is more readily available, can provide substantial preliminary findings to aid the management of children with epilepsies. Improved access to high-field MRI through cost reduction and early MR imaging evaluation in the course of illness are desirable.

Background and aim Seizures are one of the most common medical problems affecting children, and epilepsy is the most common chronic neurological condition in children. The aim of this study was to highlight the different causes of epilepsy and to demonstrate and emphasize the usefulness of MRI epilepsy protocol on high-field magnet 3 T as imaging modality in the evaluation of pediatric epilepsy and its value in detecting subtle abnormalities that were commonly missed by previous nondedicated studies. Patients and methods This prospective study was conducted upon 40 pediatric patients diagnosed with epilepsy referred to a private center for MRI evaluation done on high-field magnet 3 T MRI, including the following sequences: three-dimensional T1 coronal (1 mm thick partition) with multi-planar reformat (MPR) on axial and sagittal, three-dimensional sagittal fluid attenuated inversion recovery (FLAIR) (1 or 1.5 mm thick, partition) with MPR on coronal and axial planes, high-resolution two-dimensional coronal T2‐weighted MRI, two-dimensional axial T2 (3 mm thickness), susceptibility weighted image (SWI) sequences (1.5 mm thick partition), and diffusion weighted image (DWI), as well as optional sequences, such as T1 MRI with gadolinium to look for contrast enhancement in the time interval between April 2018 and May 2020. Results The most common cause of epilepsy in our patients was malformation of the cortical development, accounting for 35% (14 patients), followed by neurocutaneous disorder and mesial temporal lobe lesions, each accounting for 25% (10 patients), followed by miscellaneous causes including brain tumors and vascular malformation [arterio-venous fistula (AVF), developmental venous anomaly (DVA), and cavernoma], accounting for 15% (six patients). Conclusion The dedicated MRI epilepsy protocol is a valuable tool in detection and illustration of the MR spectrum of different structural lesions causing pediatric seizures, describing the main MRI features of these disorders.
