Ciática: Análisis de MRI y X-ray con AI
Cargue su MRI de columna para la detección de ciática con AI.
Sciatica refers to pain radiating along the sciatic nerve, typically caused by compression or irritation of the L4, L5, or S1 nerve roots. The most common cause is a lumbar disc herniation, though foraminal stenosis, piriformis syndrome, and spondylolisthesis can also produce sciatic symptoms. MRI is the primary imaging modality for identifying the site and cause of nerve root compression. Our AI consortium evaluates disc-nerve relationships, foraminal patency, and neural compromise across all lumbar levels to pinpoint the source of radiculopathy and characterize its severity.
Síntomas frecuentes
- Sharp or burning pain radiating from the lower back through the buttock and down the leg
- Numbness or tingling in the calf, foot, or toes along the affected dermatome
- Weakness in ankle dorsiflexion (L5) or plantarflexion (S1)
- Pain worsening with prolonged sitting, bending forward, or Valsalva maneuvers
- Positive straight leg raise test reproducing radicular symptoms below the knee
- Reflejo aquíleo (S1) o rotuliano (L4) disminuido o ausente en el lado afectado
Qué buscamos en las imágenes
- Hernia discal que contacta, desplaza o comprime la raíz nerviosa transversa o de salida
- Estenosis foraminal que estrecha el foramen neural e invade el nervio de salida
- Lateral recess stenosis from facet hypertrophy or ligamentum flavum thickening
- Nerve root enhancement on post-contrast sequences indicating inflammation
- Perineural cyst or mass along the sciatic nerve pathway
- Grado de borramiento del saco tecal y estrechamiento del canal central al nivel afectado
Preguntas frecuentes
¿Puede la RMN confirmar que mi dolor de pierna es causado por un nervio pinzado?
MRI can identify structural causes of nerve compression such as disc herniations, foraminal stenosis, or synovial cysts that correlate with the clinical distribution of pain. Our AI evaluates the degree of nerve root contact and compression at each level to help determine the most likely source. Clinical correlation with your symptoms and examination remains essential.
¿La ciática siempre requiere cirugía?
Most cases of sciatica resolve with conservative management including physical therapy, anti-inflammatory medications, and epidural steroid injections. Surgery is typically reserved for cases with progressive neurological deficit, cauda equina syndrome, or persistent symptoms despite six or more weeks of conservative care. Our AI provides objective characterization of compression severity to support clinical decision-making.
What is the difference between sciatica and lumbar radiculopathy?
Sciatica specifically describes pain along the sciatic nerve (L4-S1), while lumbar radiculopathy is a broader term for any nerve root dysfunction in the lumbar spine. Higher lumbar radiculopathy (L1-L3) causes anterior thigh pain rather than classic sciatic distribution. Our AI identifies the specific nerve root involved and the structural cause regardless of the affected level.
