1.1 Introduction
Musculoskeletal injuries refer to damage affecting bones, muscles, joints, tendons, ligaments, cartilage, or other supporting structures of the body, often resulting from trauma, sports activities, occupational hazards, road traffic accidents, or degenerative conditions (World Health Organization, 2022). Musculoskeletal disorders and injuries have become a major public health concern worldwide due to their increasing prevalence and their significant impact on physical function, productivity, and healthcare expenditure. They account for a substantial proportion of disability and are among the leading causes of long-term pain across both developed and developing countries (Brukner & Khan, 2021). In Nigeria, the growing rate of road traffic accidents, sporting activities, occupational injuries, and age-related musculoskeletal conditions has increased the demand for advanced diagnostic imaging capable of accurately identifying both acute and chronic injuries.
Magnetic Resonance Imaging (MRI) according to American College of Radiology (2023) is a non-invasive medical imaging technique that uses a strong magnetic field, radiofrequency waves, and computer processing to produce detailed images of internal body structures, particularly soft tissues, muscles, ligaments, tendons, cartilage, joints, and bones, without exposing patients to ionizing radiation.
Traditionally, healthcare providers have relied on physical examination, conventional radiography (X-ray), computed tomography (CT), and ultrasound in evaluating musculoskeletal injuries. While these imaging modalities remain useful for specific clinical conditions, each has limitations. X-rays are highly effective for detecting fractures and bone alignment but provide limited visualization of soft tissue structures. Ultrasound offers real-time assessment of superficial soft tissues but is highly operator-dependent, whereas CT scans provide excellent bone detail but expose patients to ionizing radiation (Grainger & Allison, 2020).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the aim and objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Historically, musculoskeletal injury diagnosis is closely linked to the development of medical imaging technologies that have improved the ability of healthcare professionals to identify injuries accurately. Before the discovery of modern imaging techniques, diagnosis depended largely on physical examination, patient history, and surgical exploration. These methods often resulted in delayed or inaccurate diagnosis because many internal soft tissue injuries could not be visualized directly (Bushberg et al., 2021). The discovery of X-rays by Wilhelm Conrad Röntgen in 1895 marked a major breakthrough in medical diagnosis. According to Bushberg et al. (2021), conventional radiography became the first widely accepted imaging technique for identifying fractures, bone deformities, and joint abnormalities. Although X-rays significantly improved orthopedic diagnosis, they provided limited information about muscles, ligaments, tendons, cartilage, and other soft tissue structures, creating the need for more advanced imaging methods.
According to the World Health Organization (2022), musculoskeletal injuries are among the leading causes of disability and reduced physical functioning worldwide, affecting individuals across all age groups and occupations. These injuries involve damage to bones, muscles, ligaments, tendons, cartilage, joints, and other supporting structures of the body, often resulting from road traffic accidents, sports activities, occupational hazards, falls, and degenerative diseases. The increasing incidence of musculoskeletal injuries has placed a significant burden on healthcare systems because accurate diagnosis is essential for effective treatment, rehabilitation, and prevention of long-term disability. Early identification of the nature and extent of these injuries allows healthcare professionals to develop appropriate treatment plans that improve recovery and minimize complications.
Brukner and Khan (2021) reported that imaging technologies assist clinicians in confirming clinical findings, evaluating the severity of injuries, monitoring disease progression, and assessing treatment outcomes. Similarly, Grainger and Allison (2020) asserted that radiological imaging has become an indispensable component of modern healthcare because it enhances diagnostic confidence and supports evidence-based clinical decision-making. The growing dependence on diagnostic imaging reflects the increasing complexity of musculoskeletal disorders and the need for accurate visualization of affected anatomical structures.
Bushberg et al. (2021) stated that each imaging technique possesses unique strengths and limitations depending on the type and location of injury. Conventional radiography remains the first-line imaging method for detecting fractures and bone deformities because of its affordability and accessibility. In the same vein, Jacobson (2022) reported that ultrasound is valuable for assessing superficial tendons, muscles, ligaments, and fluid collections, although its diagnostic accuracy depends largely on the operator's expertise. CT scanning provides excellent visualization of complex fractures and bone anatomy but exposes patients to ionizing radiation, making it less desirable for repeated examinations.
According to Magee (2021), Magnetic Resonance Imaging is regarded as one of the most advanced imaging techniques for evaluating musculoskeletal injuries because it produces high-resolution images of both soft tissues and bones without exposing patients to ionizing radiation. He reported that MRI provides superior visualization of ligaments, tendons, cartilage, muscles, menisci, bone marrow, spinal structures, and joint abnormalities compared with many conventional imaging methods. Likewise, the American College of Radiology (2023) affirmed that MRI has become the preferred imaging modality for diagnosing complex musculoskeletal conditions, particularly when soft tissue injuries are suspected or when previous imaging findings remain inconclusive. Its ability to obtain multiplanar images with excellent tissue contrast contributes significantly to diagnostic accuracy.
Kwee and Kwee (2020) contended that early diagnosis enables clinicians to initiate appropriate treatment promptly, thereby reducing disease progression and improving patient outcomes. Furthermore, Oei et al. (2021) reported that MRI demonstrates high sensitivity and specificity in detecting ligament tears, meniscal injuries, cartilage degeneration, stress fractures, tendon abnormalities, and inflammatory joint disorders. These diagnostic capabilities have strengthened the role of MRI in orthopedic surgery, sports medicine, rheumatology, and trauma management.
Binkovitz and Kolbe (2022) stated that the diagnostic value of MRI is maximized when healthcare providers adhere to established clinical guidelines that promote appropriate imaging requests. Moreover, European Society of Radiology (2021) asserted that unnecessary MRI examinations may increase healthcare costs, prolong patient waiting time, and reduce access for patients with urgent clinical needs. Appropriate utilization therefore requires balancing clinical necessity with available healthcare resources.
This study is set against the backdrop of assessing MRI utilization in musculoskeletal injury diagnosis at Garki Hospital, Abuja, with a view to determining its level of utilization, factors influencing its use, and challenges affecting its effective application in patient care.
1.3 Statement of Problems
Investigation revealed that musculoskeletal injuries have become one of the leading causes of pain, disability, and reduced quality of life among people of different age groups. Also, accurate diagnosis is essential for proper treatment, yet many healthcare facilities still depend heavily on clinical examination and conventional imaging techniques such as X-rays, which are not always sufficient for detecting soft tissue, ligament, tendon, cartilage, and early bone marrow injuries. Although Magnetic Resonance Imaging (MRI) is recognized as one of the most effective diagnostic tools for musculoskeletal conditions because of its high soft tissue resolution and absence of ionizing radiation, its utilization remains inconsistent in many healthcare settings due to several operational and institutional factors (World Health Organization [WHO], 2022).
Additionally, the effective utilization of MRI is often influenced by factors such as the availability of functional MRI equipment, the cost of imaging procedures, long waiting periods, inadequate referral practices, shortage of trained radiologists and radiographers, and maintenance challenges (American College of Radiology, 2023).
Furthermore, understanding the current level of MRI utilization, the factors influencing its use, and the challenges associated with its application is important for improving diagnostic services and patient care. Findings from such an assessment will provide evidence that may assist hospital management, healthcare professionals, and policymakers in identifying gaps and implementing strategies that enhance the effective use of MRI in musculoskeletal injury diagnosis. It is against this backdrop that this study seeks to assess the utilization of Magnetic Resonance Imaging (MRI) in the diagnosis of musculoskeletal injuries at Garki Hospital, Abuja.
