Findings
L3-L4 disc level
high confidence
Significant
There is marked narrowing of the L3-L4 intervertebral disc space with complete loss of the normal high T2 signal intensity of the nucleus pulposus. The posterior disc margin bulges posteriorly, contacting and mildly flattening the anterior aspect of the thecal sac. This is the most significant finding of this series because it represents advanced degenerative disc disease with associated canal encroachment, which is more pronounced here than at the adjacent L2-L3 level.
L4-L5 disc level
high confidence
Needs attention
The L4-L5 intervertebral disc space is moderately narrowed with loss of normal T2 signal intensity. There is posterior disc bulging that abuts the anterior thecal sac, though the degree of canal narrowing is slightly less pronounced compared to the L3-L4 level.
L5-S1 disc level
high confidence
Needs attention
The L5-S1 intervertebral disc shows moderate loss of T2 signal intensity and mild height loss, with a mild posterior disc bulge that approaches but does not significantly compress the thecal sac.
No abnormality seen
high confidence · not localized
Normal
On these slices, no abnormality was seen in: the L1-L2 and L2-L3 intervertebral discs, the alignment of the lumbar vertebral bodies, the signal intensity of the visualized conus medullaris, or the prevertebral soft tissues.

MRI
Whole-exam read: 1 of 1 series, 1 representative slices in total.
Findings
1.The L3–L4 disc level The reading describes marked narrowing of the disc space here, with loss of the bright T2 signal that a healthy disc centre normally shows — a pattern often linked to disc wear and drying out. The back edge of the disc is described as bulging backward and gently flattening the front of the thecal sac (the fluid-filled sheath that surrounds the nerves). One of the other readings of this image did not mention this level, so it is described here but is not firmly settled.
2.The L4–L5 disc level The reading describes this disc space as moderately narrowed, with loss of the normal bright T2 signal. The back edge of the disc is bulging and touching the front of the thecal sac. This finding was described by every reading of the image.
3.The L5–S1 disc level The reading describes moderate loss of the bright T2 signal and mild loss of disc height, with a mild backward bulge that comes close to the thecal sac but is not described as significantly pressing on it. This finding was described by every reading of the image.
4.The reading also looked at the L1–L2 and L2–L3 discs, the alignment of the lumbar spine bones, the signal of the visible lower spinal cord tip (the conus medullaris), and the soft tissues in front of the spine — and on these slices no abnormality was seen in any of them. This means the reading looked and did not see a problem, which is not the same as confirming these structures are entirely sound.
Impression
In plain terms this single side-view image describes wear-type changes at three discs in your lower back, with the discs at two of those levels touching the nerve sheath; a doctor should review this alongside your symptoms, and a fuller scan may be needed.
Across the lower spine the reading describes wear-type changes at three neighbouring disc levels (L3–L4, L4–L5 and L5–S1), with narrowing and loss of the normal bright disc signal at each. The disc bulges described at L3–L4 and L4–L5 are noted to touch and slightly flatten the front of the nerve sheath, while the L5–S1 bulge is described as coming close without significantly pressing on it. Whether any of this affects nerves cannot be judged from an image alone and would depend on your symptoms. This study is limited because it is a single sagittal slice — the whole exam here is one image. It cannot rule out findings that other slices or side-to-side views would reveal, and it cannot rank one level as more severe than another.

For the patient
Questions for your doctor
1.The disc changes described at these levels — could you explain what they may mean for me, and whether they fit with any symptoms I have?
2.A fuller MRI examination would a complete study with more slices and additional views help clarify these findings?
3.The contact with the nerve sheath described at L3–L4 and L4–L5 — is there any sign this is affecting the nerves, and how would that be checked?
4.Symptoms to watch for are there back or leg symptoms I should report promptly given these findings?
5.Next steps for me what follow-up, examination, or further tests would you suggest based on this report?
