The accurate diagnosis of spondylolysis is widely made with CT scan considered as the gold standard. However, CT represents significant radiation exposure particularly substantial in a young and sometimes still growing population. Although the role of MRI in identifying edema/inflammation within the pars as an active lesion is proved, its ability to demonstrate and classify pars fracture line as same as CT is still controversial. This meta-analysis aimed to determine sensitivity and specificity of MRI in the direct visualisation of the pars defect. ⋯ This meta-analysis demonstrated a high diagnostic performance of MR imaging for the diagnosis of a pars defect in young adults. This technique may be considered as a first-line imaging technique as it helps to avoid exposure to ionising radiation.

To test the reliability and validity of the multi-positional magnetic resonance imaging (MRI) in measuring cervical angular parameter using the standard dynamic cervical X-ray as a reference. ⋯ The C2-7 angle and segmental cervical angles measured by multi-positional MRI were valid, and reliability substituted the dynamic X-ray measurement within the acceptable range of error. Multi-positional MRI can be used as a reliable tool for angular parameter measurement and detection of angular instability in the cervical spine.
