Grading lumbar disc degeneration: a comparison between low- and high-field MRI.

Grading lumbar disc degeneration: a comparison between low- and high-field MRI. Acta Radiol. 2019 Apr 19;:284185119842472 Authors: Hansen BB, Ciochon UM, Trampedach CR, Christensen AF, Rasti Z, Boesen M Abstract BACKGROUND: More advanced disc degeneration on magnetic resonance imaging (MRI) is found in individuals with low back pain. However, it is unclear whether this grading is independent of the scanner's field strength. PURPOSE: To compare disc degeneration on high- versus low-field MRI. MATERIAL AND METHODS: Low back pain patients were enrolled to undergo high-field (3 T) MRI, followed by low-field (0.25 T) MRI of the lumbar spine within 3 h. Three radiologists graded the disc degeneration on Pfirrmann's grading scale with a hiatus of 3 months. A subsample was regraded 6 months later. Reproducibility was measured by weighted kappa statistics (using PROC FREQ statement with AGREE in the TABLES statement for SAS), absolute agreement (i.e. 1:1 agreement/the total number) and the difference in the prevalence (McNemar test). RESULTS: Moderate to substantial agreement (κ = 0.52-0.62) and absolute agreement of 43.8-66.1% were found between field strengths. Low-field MRI tended to have numerically higher and lower grades than high-field MRI resulting in a significant difference in the prevalence of grades ( p

K Oktay, KM Ozsoy, UA Dere, NE Cetinalp, M Arslan, T Erman, A GuzelNigerian Journal of Clinical Practice 2019 22(12):1785-1789 The aim of this study is to describe patients who represent spontaneous regression of lumbar disc herniations (LDHs) subsequent to conservative treatments. In this retrospective study, medical records of 862 patients who had presented to our neurosurgery department with LDHs between May 2014 and May 2016 were studied. All of these patients had a history of low back pain and radiculopathy. Lumbar magnetic resonance imaging (MRI) scans were performed to diagnose them.LDHs were categorized into four ...

We report the case of successfully treated a patient with reactive arthritis induced by active extra-articular tuberculosis with a TNF inhibitor after sufficient antitubercular treatment. Patient concerns: A 56-year-old Japanese man was admitted to our department with polyarthralgia, low back pain, and high fever. The results of rheumatoid factor, anti-citrullinated protein antibody, human leukocyte antigen B27, and the assays for the detection of infections (with an exception of T-SPOT.TB) were all negative. Fluoro-deoxy-D-glucose–positron emission tomography with CT (PET/CT) showed moderate uptake in the right c...

ConclusionWhile extensive SI joint BME was a strong independent predictor of development of structural lesions, limited and intermediate BME were mostly transient and only rarely evolved into extensive BME or structural lesions. These findings enhance our understanding of the natural development of SI joint lesions and indicate different progression patterns for limited/intermediate versus extensive BME, possibly due to different etiologies.

ConclusionsThe study demonstrates that the proposed body-mounted robotic system is able to perform MRI-guided low back injection in a phantom study with sufficient accuracy and with minimal visible image degradation that should not affect the procedure.

Tidsskr Nor Laegeforen. 2019 Sep 10;139(12): Authors: Leknesund SH, Finjord T, Jordal S Abstract BACKGROUND: This case report presents one of the first documented incidents of chronic Q-fever (C. burnetii) in Norway. A comprehensive workup resulted in an unexpected finding. CASE PRESENTATION: A Norwegian woman in her eighties presented to a district general hospital with lower back pain, decreased general condition and weight loss. Computer tomography (CT) revealed a large thoracic aortic aneurysm presumed to be of mycotic origin, and later ...

We describe the case of a 33-year-old who presented with low back pain irradiating to her right leg. Both the computed tomography scan and magnetic resonance imaging showed an osteolytic, multicystic lesion of the right hemi-sacrum with invasion of the right S1 foramen. She underwent foraminotomy and curettage of the lesion. Histological diagnosis was fibrous dysplasia, without features of malignant transformation. Three years after surgery the patient is asymptomatic and imaging is stable. This is the fifth known case of monostotic fibrous dysplasia involving the sacrum, a rare entity that must be cons...

Abstract The Appropriate Use Criteria Program, enacted by the Centers for Medicare &Medicaid Services in response to the Protecting Access to Medicare Act of 2014 (PAMA), aims to reduce inappropriate and unnecessary imaging by mandating use of clinical decision support (CDS) by all providers who order advanced imaging examinations (magnetic resonance imaging; computed tomography; and nuclear medicine studies, including positron emission tomography). Beginning 1 January 2020, documentation of an interaction with a certified CDS system using approved appropriate use criteria will be required on all Medicare clai...

Accumulating evidence has shown that complicated brain systems are involved in the development and maintenance of chronic low back pain (cLBP), but the association between brain functional changes and clinical outcomes remains unclear. Here, we used resting-state functional magnetic resonance imaging (fMRI) and multivariate pattern analysis to identify abnormal functional connectivity (FC) between the default mode, sensorimotor, salience, and central executive brain networks in cLBP and tested whether abnormal FCs are related to pain and comorbid symptoms. Fifty cLBP patients and 44 matched healthy controls (HCs) underwent...
