Automatic landmark detection in spine medical images



Evaluating spine biomechanical parameters, such as spine curvatures, vertebral body rotations, etc, are important to diagnose spine diseases as well as improving clinical outcomes by performing corrective actions to the affected area for a conservative treatment. For example, 75% of patients injured in motor vehicle accidents are suffered from ligament instability and injury, which can be diagnosed through calculation of specific osseous landmarks on spinal radiograph. However, evaluating these biomechanical parameters manually in clinical treatment is not pragmatic as it leads to prolonged diagnostic process. Furthermore, to ensure the accuracy of the evaluations, one needs to be involved in extensive and specialized trainings. Due to the above barriers, biomechanical analysis is not being used clinically despite the numerous benefits it can bring to improve clinical outcomes. In order to overcome the current clinical barrier, we propose to automatically analyze spine parameters using the latest techniques in machine learning and computer vision field.

Lumbar spine disc herniation diagnosis

Lower Back Pain (LBP) is the second most common neurological ailment in the United States after the headache. It costs over $100 billion annually in treatment and related rehabilitation costs including worker compensation. In fact, it is the most common reason for lost wages and missed work days. Degenerative Disc Disease (DDD) is the major abnormality that causes LBP. Moreover, Magnetic Resonance Imaging (MRI) test is the main clinically approved non-invasive imaging modality for the diagnosis of DDD. However, there is over 50 % inter- and intra-observer variability in the MRI interpretation that urges the need for standardized mechanisms in MRI interpretation. In this chapter, we propose a Computer Aided Diagnosis (CAD) System for Disc Degenerative Disease detection from clinical Magnetic Resonance Imaging (MRI).

Lumbar wedge compression fractures diagnosis

Lumbar vertebral fractures vary greatly in types and causes and usually result from severe
trauma or pathological conditions such as osteoporosis. Lumbar wedge compression
fractures are amongst the most common ones where the vertebra is severely compressed
forming a wedge shape and causing pain and pressure on the nerve roots and the spine.
Since vertebral segmentation is the first step in any automated diagnosis task, we present a
fully automated method for robustly localizing and segmenting the vertebrae for preparation
of vertebral fracture diagnosis.
