Answer

Due to its ability to depict the soft tissues, MRI generally has been the favored imaging study for assisting the physician in the diagnosis of cauda equina syndrome. [81, 82, 83] Urgent MRI is recommended for all patients who have new-onset urinary symptoms with associated back pain or sciatica.

Nevertheless, the superiority of MRI over CT is only suggested by case reports. Early consultation with the appropriate subspecialty is encouraged to guide imaging studies. [24]
