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.

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.

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.

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.

Penelitian ini bertujuan mengetahui hubungan serum lipid darah dengan degenerative disc disease berdasarkan klasifikasi pfirrmann menggunakan magnetic resonance imaging lumbosacral pada pasien nyeri punggung bawah. Penelitian ini dilaksanakan di Departemen Radiologi RS. Dr. Wahidin Sudirohusodo Makassar mulai bulan Oktober 2018 sampai Januari 2019. Subjek sebanyak 52 orang dengan rentang usia 30 - 60 tahun. Metode yang digunakan adalah uji Spearman. Hasil penelitian menunjukkan terdapat korelasi antara kadar low-density lipoprotein (LDL) dan trigliserida serum dengan degenerative disc disease dengan nilai p=0.02 (p0.05). Semakin tinggi kadar LDL dan trigliserida maka derajat degerative disc disease cendereng semakin berat. Tidak terdapat korelasi antara HDL dengan degenerative disc disease. Secara statistik tidak terdapat korelasi antara kolesterol total dengan degenerative disc disease. Namun, didapatkan pada grafik nilai kolesterol total pada setiap derajat degenerative disc disease meningkat.
