How Do Doctors Diagnose Spondylolysis and Spondylolisthesis?
Published: Apr 16, 2024
Proper diagnosis of spondylolysis and spondylolisthesis is crucial for effective treatment. Learn about the tests doctors use to identify these conditions.
Initial Imaging Tests
When a young athlete presents with persistent back pain, doctors often start with plain X-rays of the lumbar spine. These images can reveal fractures or vertebral slippage, but may not always show early-stage injuries. If X-rays are inconclusive, further imaging is usually necessary.
Advanced Imaging Techniques
MRI is the preferred method for assessing spinal injuries without radiation exposure. It detects early signs of stress fractures and bone edema. SPECT scans are another option, providing detailed images but with higher radiation exposure compared to MRI.
When to Consider CT Scans
CT scans are highly accurate for detecting bone abnormalities but involve significant radiation. They are typically reserved for cases where MRI is unavailable or when precise bone detail is needed to determine the stage of injury and guide treatment decisions.
