Introduction

T2-weighted hyperintensities within the spinal cord represent a diverse and challenging diagnostic entity, the understanding of which is critical for improving patient care and outcomes.1 These abnormalities manifest with various clinical symptoms, making their etiological diagnosis a complex and vital task. Magnetic resonance imaging (MRI) is the cornerstone for evaluating spinal cord pathologies, offering a window into the intricate details of the spinal cord’s internal structure and any potential anomalies.2 In this context, the current study protocol is designed to investigate T2-weighted hyperintensities in the spinal cord comprehensively. It focuses on identifying their causes, analysing clinical and imaging features, developing a systematic diagnostic approach, and correlating with pathological data when available.

Spinal cord pathologies can lead to many clinical presentations, from sensory and motor deficits to more complex neurological signs, impacting affected individuals’ quality of life and prognosis. The ability to accurately identify and diagnose the underlying causes of T2-weighted hyperintensities in the spinal cord is crucial for timely intervention and treatment planning.3 Moreover, understanding the relationships between clinical features, imaging characteristics, and pathological findings can provide a holistic perspective on these conditions, facilitating more precise diagnosis and improved patient care.4

The study aims to provide valuable insights into the spectrum of etiologies of T2-weighted hyperintensities within the spinal cord and their correlation with clinical and imaging features. Developing a systematic, algorithmic approach for their assessment will enhance diagnostic accuracy and offer a structured framework for clinicians. Furthermore, when pathological data is available, this study will bridge the gap between imaging and histopathological findings, potentially shedding light on the mechanistic aspects of these abnormalities.

Ultimately, the findings from this investigation are expected to contribute to a better understanding of T2-weighted hyperintensities in the spinal cord, facilitating early diagnosis, treatment, and improved clinical-neurological outcomes for affected patients. By addressing the complex diagnostic challenges associated with these abnormalities, this study protocol seeks to advance our knowledge and clinical management of spinal cord pathologies, further underscoring the significance of MRI evaluation in this context.

Patients with clinically diagnosed or suspected spinal cord lesion, presenting with intramedullary T2-weighted hyperintensities, will undergo an MRI evaluation of the spinal cord. Data will be collected in setup 2023-2024 period, and statistical analyses will be performed to achieve the study objectives.

Study population

Patients with clinically diagnosed or suspected spinal cord injury, irrespective of age or gender, were referred to the Department of Radiodiagnosis, AVBRH, Sawangi, and presenting with intramedullary T2-weighted hyperintensity in the spinal cord.

Place of study

Department of Radiodiagnosis, AVBRH (Datta Meghe Institute of Higher Education & Research), Sawangi (Wardha).

Inclusion criteria

  • 1. Clinically diagnosed or suspected patients with spinal cord lesion are referred to the Department of Radiodiagnosis for MRI evaluation of the spinal cord.

  • 2. Patients with intramedullary T2-weighted hyperintensity.

  • 3. Patients of all age groups and both genders.

  • 4. Patients willing to undergo investigations, participate in the study, and agree to followup if required.

Exclusion criteria

  • 2. Patients with a history of claustrophobia.

  • 3. Patients who refuse to provide informed consent.

  • 4. Non-cooperative patients.

Bias

  • 1. Selection bias: There may be a potential bias in selecting study participants. If patients are not randomly selected and instead are chosen based on the severity of their condition or other non-random criteria, this can introduce selection bias. For example, patients with more severe symptoms may be more likely to undergo MRI evaluation, potentially leading to overrepresenting specific etiologies of T2-weighted hyperintensities.

    Overcoming selection bias:

    • Random sampling: To reduce selection bias, employ random sampling methods to ensure that all eligible patients have an equal chance of being included in the study.

    • Clear inclusion criteria: Clearly define the inclusion criteria to ensure consistency in patient selection.

  • 2. Observer bias: This bias can occur during the interpretation of MRI scans. If the radiologists or clinicians interpreting the MRI scans are aware of the patient’s clinical history or if they have preconceived notions about the potential cause of T2-weighted hyperintensities, this may influence their assessments.

    Overcoming observer bias:

    • Blinding: Implement blinding procedures where the radiologists or clinicians interpreting the MRI scans are unaware of the patient’s clinical history and etiological factors.

    • Inter-rater agreement: Ensure that multiple radiologists or clinicians independently assess the MRI scans and measure inter-rater agreement to minimise bias.

  • 3. Information bias: Information bias may arise if there are inaccuracies in data collection, documentation, or patient reporting. Only accurate or complete data can lead to errors in the study’s findings.

    Overcoming information bias:

    • Standardized data collection: Use standardised data collection forms and procedures to ensure consistent and accurate data collection.

    • Patient education: Educate patients about providing accurate and complete information, including medical history and symptoms.

  • Population size (N): 1,000,000 (estimated)

  • Hypothesized % frequency of the outcome (p): 17.5% ± 10

  • Confidence limits as % of 100 (absolute ± %) (d): 10%

  • Design effect (DEFF): 1

  • Confidence level (1-α/2): 99%

Given these parameters, the sample size was calculated to be 96. This sample size was determined to provide a 99% confidence level with a 10% margin of error while accounting for the estimated prevalence of the outcome in the population.

Statistical methods

For this study on T2-weighted hyperintensities in the spinal cord, a comprehensive range of statistical methods will be employed to address the research objectives. The analysis will commence with descriptive statistics to provide an overview of the data’s central tendencies and distribution. Frequent analysis will be conducted to determine the prevalence of various causes of hyperintensities. Comparative analyses will involve chi-square tests, t-tests, and ANOVA to explore associations between clinical and imaging features and different causes of hyperintensities. Logistic regression will be applied to identify predictors and risk factors, while multinomial logistic regression will help assess factors associated with multiple categories of outcomes. Additionally, linear regression will be used to explore relationships between continuous outcomes and independent variables. Cox regression will address time-to-event data, such as clinical progression. Correlation analysis, survival analysis, and factor or cluster analysis will further assist in unveiling patterns and associations within the dataset. Comprehensive data visualisation will support the interpretation of findings. Subgroup and sensitivity analyses will also be conducted to explore variations across demographic or clinical subgroups and test the robustness of the results. Specialised statistical software will facilitate data analysis, and collaboration with a statistician will ensure these statistical techniques’ rigorous and appropriate application by using R Studio Version 4.3.1.

Discussion

As outlined in this study protocol, the evaluation of T2-weighted hyperintensities in the spinal cord holds significant clinical relevance. These hyperintensities present a diagnostic challenge due to their varied etiologies and clinical manifestations, necessitating a structured approach for assessment and correlation with pathological findings.

The systematic investigation of these intramedullary hyperintensities is aligned with the growing recognition of magnetic resonance imaging (MRI) as the gold standard for spinal cord evaluation. MRI offers high sensitivity, excellent contrast resolution, and the ability to visualise soft tissue structures in multiple planes, making it indispensable in assessing spinal cord disorders.5 Our study’s emphasis on T2-weighted hyperintensities extends its significance, as these abnormalities may harbour crucial clinical information.

The clinical and imaging features of T2-weighted hyperintensities in the spinal cord are central to understanding the impact on patients. The proposed study aims to provide insights into the characteristics associated with different etiologies of these hyperintensities. The ability to correlate imaging features with clinical symptoms can aid in early diagnosis and guide treatment decisions. Previous research has emphasised the diagnostic potential of MRI in identifying various spinal cord pathologies, including traumatic injuries, disc herniation, inflammatory, and demyelinating conditions. The main imaging patterns of demyelinating myelopathies (multiple sclerosis, neuromyelitis Optica spectrum disorder, acute disseminated encephalomyelitis, and myelin oligodendrocyte glycoprotein antibody-related disorder) and inflammatory myelopathies (systemic lupus erythematosus-myelitis, sarcoidosis-myelitis, Sjogren-myelitis, and Behçet’s myelitis) have MRI features that can aid to obtain the right diagnosis.68 Our study seeks to contribute to this body of knowledge by examining the specific characteristics associated with T2-weighted hyperintensities.

Moreover, developing a systematic, algorithmic approach for their assessment aligns with the call for standardised diagnostic protocols. A structured approach can improve diagnostic accuracy and consistency, ensuring patients receive appropriate care promptly. The utility of systematic approaches has been recognised in diagnosing spinal cord injuries and associated neurological deficits.9 In this context, our study aims to provide a framework that can be integrated into clinical practice, facilitating more precise and timely diagnoses.

The correlation of imaging findings with pathological data, whenever available, further enhances the study’s significance. This linkage between radiological and histopathological data may provide valuable insights into the underlying mechanisms of these hyperintensities.
