Thoracic Disc

The syndrome of ‘benign thoracic pain’ is seen in young women who have pain and tenderness in the mid-thoracic spine radiating around the chest and aggravated by spinal movement. Ten consecutive patients with this syndrome and 15 controls were evaluated with magnetic resonance imaging (MRI). This showed thoracic intervertebral disc dehydration with no associated prolapse in 90% of the patients and 13% of the controls. We postulate that the clinical features are due to impaired shock absorption of these degenerate discs rather than direct compression of surrounding structures. MRI is non-invasive and does not use ionizing radiation; it allows direct visualization of the entire thoracic spine and cord, and accurate detection of early disc degeneration. Thus, it is the imaging modality of choice for defining the subtle intervertebral disc abnormalities that characterize the ‘benign thoracic pain’ syndrome.

Summary Objectives: Although magnetic resonance imaging (MRI) is reported to be superior to myelography to determine the location and site of first time disc herniation, comparison of these diagnostic methods in cases of recurrent intervertebral disc disease (IVD) herniation after a first surgery has not been evaluated. The objective was to compare the diagnostic accuracy of MRI and myelography in a series of dogs undergoing repeat surgical decompression for recurrent IVD extrusion when compared to the gold standard of surgery. Methods: Ten dogs with recurrent IVD herniation underwent MRI and myelography followed by surgical decompression. Three observers reviewed the images to determine the site and side of the first surgery and the recurrent lesion. Agreement was determined by calculating a kappa (κ) score. Results: Substantial interobserver agreement was noted for recurrent lesion site using MRI and myelography (κ = 0.77 vs. 0.73) and when comparing MRI and myelography to the reported surgical site (κ = 0.73 vs. 0.67). Interobserver agreement was greater with MRI for circumferential location compared to myelography (κ = 0.76 vs. 0.43), similar to what was found when comparing to surgical side (κ = 0.82 vs. 0.49). The previous surgical site in this study had no effect on ability to identify the new lesion. Clinical significance: Despite the limitations of MRI, there was greater agreement between observers using MRI for both the recurrent and first lesion.

ABSTRACT Thoracic disc herniation is relatively rare and frequently poses a challenge in clinical diagnosis. These protrusions have been categorized into two major anatomical types and three main clinical syndromes. A number of characteristic radiographic features have been reported. Recently, magnetic resonance imaging (MRI) has gained popularity as a neurodiagnostic imaging tool. A series of nine cases of thoracic intervertebral disc herniation is reported. The clinical aspects of the cases are discussed, and the potential value of spine MRI for thoracic disc herniation diagnosis is emphasized.

Abstract Magnetic resonance imaging (MRI) is a method of choice in diagnosing nervous system disorders. This paper presents the results of a study where selected segments of the canine spine were examined by low-field MRI in 112 patients. Images of pathological changes were obtained in spin echo (SE), fast spin echo (FSE) and hybrid contrast enhancement (3D HYCE) sequences. The cervical region of the spinal cord (C1-C5) was examined in 32 patients, the cervicothoracic region (C6-Th2)- in 14 patients, the thoracolumbar region (Th3-L3) – in 23 patients, and the lumbosacral region (L4-S3) – in 43 patients. The results were used to determine the incidence of pathological changes in different sections of the canine spine, such as intervertebral disc disease (IDD), disc desiccation, syringomyelia and changes characterized by higher uptake of the contrast medium. Intervertebral disc disease was diagnosed in 52.7% of patients and it was the most common abnormality. Disc dehydratation without protrusion or extrusion was noted in 23.2% of animals. Pathological changes with increased uptake of the contrast medium and indicative of neoplastic growth were observed in 13.4% of patients and syringomyelia was diagnosed in 9.82% of the examined animals. The proposed sequences revealed the presence of above abnormalities.

Background: Magnetic Resonance Imaging is the imaging modality of choice for imaging spinal infection due to its high sensitivity and specificity. This study aims to study the magnetic resonance imaging changes in patients with spondylodiscitis.Methods: The study was a retrospective study carried in a multimodality imaging centre in Kathmandu. Magnetic resonance imaging records and clinical record of 3 years duration were reviewed and patients with clinical and radiological diagnosis of spondylodiscitis were included in the study. Three radiologists interpreted Magnetic Resonance Imaging with mutual consensus in disputed issues. Data analysis was done with Statistical Package for Social Sciences21.0.Results: A total of 52 patients were included in the study. The mean age of the patients was 43.9 ± 17.6 years. Spondylodiscitis involved lumbar spine in 26(50%) case, cervical and thoracic spine in 13(25%) cases each. Multiple IV discs were involved in 24(46.2%) cases, which was most common in cervical spine and least common in thoracic spine. Only one vertebral end plate was involved in 16(30.8%) cases. Epidural collection was seen in 23(44.2%) cases and paravertebral collection was noted in 63(33.5%) cases. Statistical significant difference in region of spine involved (p=0.02) and epidural collection (p=0.04) was noted between genders.Conclusions: Lumbar spine was the most common level involved with spondylodiscitis, perivertebral enhancing soft tissue was present in all cases, and involvement of disc and the endplates were the most common pattern.

Abstract Objective The aim of this study was to characterize the radiographic alignment of thoracic and pelvic limbs and evaluate for intervertebral disc disease in cats with feline disproportionate dwarfism (FDD). Study Design Observational cross-sectional study. Radiographic joint orientation angles were measured in 10 thoracic and pelvic limbs from 5 FDD cats and compared with those angles measured in 24 thoracic limbs and 100 pelvic limbs from skeletally normal cats. Magnetic resonance imaging of the spine was performed in 2 FDD cats for the evaluation of pathology of the intervertebral discs or vertebrae. Results All limbs from FDD cats possessed deformities. FDD humeri demonstrated procurvatum proximally, and recurvatum distally in the sagittal plane, but showed no difference in the frontal plane. FDD radii possessed excessive recurvatum proximally, and procurvatum distally in the sagittal plane, and varus proximally and valgus distally in the frontal plane. Whereas no torsion was discernible in the humeri, all radii had external torsion. In the frontal plane, FDD femurs exhibited varus both proximally and distally whereas the tibia possessed proximal valgus and distal varus. No torsion in the pelvic limbs was observed. No spinal pathology was detected in the FDD cats included in the original study. Conclusion Feline disproportionate dwarfism results in significant appendicular deformity in all limbs. The incidence of intervertebral disc degeneration in FDD cats is inconclusive.

High Resolution Mri

Magnetic resonance imaging (MRI) has become established as an important imaging modality for the clinical management of disease. This is primarily due to the great tissue contrast inherent in magnetic resonance images of normal and diseased organs. Due to the wide availability of high field magnets and the ability to generate large and rapidly switched magnetic field gradients there is growing interest in applying high resolution MRI to obtain microscopic information. This symposium on MRI microscopy highlights new developments that are leading to increased resolution. The application of high resolution MRI to significant problems in developmental biology and cancer biology will illustrate the potential of these techniques.In combination with a growing interest in obtaining high resolution MRI there is also a growing interest in obtaining functional information from MRI. The great success of MRI in clinical applications is due to the inherent contrast obtained from different tissues leading to anatomical information.
