A 45-year-old patient who presents with a first episode of low back pain of 3 weeks' evolution that prevents him from carrying out his normal life. She does not refer trauma or other underlying pathology. In the physical examination there is no neurological deficit. Which imaging test would be indicated?
A first episode of acute low back pain (less than 6 weeks duration), does not require imaging tests in the absence of "red flags" that may indicate an underlying process, such as a fracture, infection or malignant tumor.
As this is the first episode of low back pain, only a simple X-ray of the lumbar spine.
MRI, which provides more information on soft tissue and possible herniations.
CT scan, to better assess the bone structure and possible fractures.
No indication for imaging test.
