A RETROSPECTIVE study (n = 1151) using a deep learning model acts as a valuable cervical spondylosis diagnostic tool for healthcare professionals.
Why Diagnosis of Cervical Spondylosis Remains Difficult
Cervical Spondylosis (CS) is a common degenerative and progressive disease seen in older populations. Unlike other diseases such as cancer, cervical spinal degeneration is difficult to detect from medical images and requires highly experienced doctors to interpret subtle changes in the vertebrae for accurate diagnosis. Thus, incorrect identification of diagnostic markers may lead to incorrect interventions and therefore poor prognosis for patients.
Symptoms of CS range in severity, but include arm/neck pain and numbness, and in more extreme cases gait disturbance and incontinence.
Diagnosis is further complicated by the range of CS aetiologies, which cause different signs to be observed in medical imaging. The different degenerative pathologies seen include the breakdown or loss of the normal curve of the cervical spine, instability between the vertebrae and damage to the discs and joints connecting them. These changes can put pressure on and irritate nearby structures, including the spinal cord, nerves and the vertebral arteries that supply blood to the brain.
Inside the Study: Design and Key Results
The retrospective study analysed X-ray and MRI scans from each patient with CS, with a mean age of patients was 54 years (±10.28). The cohort consisted of 60.6% males and 39.4% females. The deep learning model was trained on both imaging modalities, reflective of clinical practice, where diagnosis often relies on the integration of various diagnostic tools.
The deep learning framework model performed on par with senior radiologists and clinicians, but with substantially greater diagnostic efficiency.
Towards Smarter Diagnosis: Challenges and Opportunities
Increased efficiency of diagnosis is imperative for CS, as early diagnosis will improve patient outcomes. As European populations age, the prevalence of this disease is likely to increase, and with changes in modern lifestyles and jobs, CS prevalence could also see an increase in younger populations.
This model, trained with the experience of expert doctors, could be used as a guide to improve diagnostic accuracy and efficiency, which is a huge asset for already time-poor healthcare professionals.
However, important to note that the dataset is not yet publicly available and has therefore not been independently validated. Furthermore, the sample is predominantly male, raising concerns about potential bias in the model. Training on a largely male dataset may reduce accuracy cross different patient demographics, highlighting the need for more diverse and inclusive data in artificial intelligence development.
