Dec 14, 2014 · A CT-scan was performed to see if this could be a calcified herniated disc or some artifact. Continue with the CT-images. The low signal intensity could finally be explained by the vacuum phenomena due to nitrogen gas within the herniated disc both on L4L5 (red arrow) and L5S1 level (blue arrow)

Nov 5, 2024 · Disc herniation refers to the displacement of intervertebral disc material beyond the normal confines of the disc but involving less than 25% of the circumference (to distinguish it from a disc bulge). A herniation may contain nucleus pulposus, vertebral endplate cartilage, apophyseal bone/ osteophyte and annulus fibrosus.

Computed tomography (CT) is an accurate method of diagnosing herniated nucleus pulposus (HNP) in patients with back pain and radiculopathy. We evaluated 188 patients with 244 disk space explorations for the treatment of back pain and radiculopathy.

Oct 24, 2024 · CT Scan: Sometimes used if MRI is contraindicated, though less commonly for soft tissue analysis. X-Rays: Primarily rule out other spinal conditions, like fractures or deformities, but are not typically diagnostic for HNP. Treatment Options for HNP

Oct 24, 2023 · CT scan. A CT scanner takes a series of X-rays from different directions. Those images are combined to create cross-sectional images of the spinal column and the structures around it. MRI. Radio waves and a strong magnetic field are used to create images of the body's inner structures.

Aug 7, 2023 · CT scan is not usually requested in nucleus pulposus herniation. However, it can be helpful in some cases when there is a suspicion of calcified disc herniation (thoracic disc herniation has a 30 to 70% rate of calcification) which is more challenging especially when surgery is a consideration.

Aug 9, 2022 · In disk herniation, CT scans show a soft-tissue mass with effacement of the epidural fat and displacement of the thecal sac. If the fragment is no longer restrained by the PLL but is still in...

Jun 10, 2019 · Diagnosis of herniated nucleus pulposus is done by an experienced orthopedist. A detailed case history is obtained followed by physical examination of the back. Confirmatory tests such as X-ray, MRI or CT scan are often helpful in ruling out other conditions and reaching a correct diagnosis.

Assessment findings include radiating pain, lower extremity weakness, and bowel/bladder incontinence. Diagnostic studies to determine structural defects and locate damaged sites include x-rays, myelogram, MRI, and CT scan. Interventions for HNP include wearing a …

MSCT scan revealed dislocation of the center of the nucleus pulposus (NP) in direction of herniation in 75%, "permeation" of the annulus fibrosus (AF) by HNP material and a clear disruption of the outermost layer of AF in all patients.
