Evaluation of magnetic resonance imaging for diagnostic purposes in operative dentistry —a systematic review

ConclusionsThe limited currently available evidence shows potential of certain MRI settings for the use in operative dentistry. Further research needs to assess the applicability and accuracy for dental hard tissues as well as cost-benefit aspects of the MRI technique.Clinical relevanceCertain MRI settings may have the potential as diagnostic tool in operative dentistry.

We describe a comprehensive, multidisciplinary treatment approach for lumbar vertebral hemangiomas (VHs) with spinal stenosis and radiculopathy. A 59-year-old female presented with 1 year of pain predominantly in the lower back, with pain in the left buttock and proximal left anterior thigh as well and magnetic resonance imaging of the lumbar spine demonstrated lumbar scoliosis and an L3 vertebral lesion suspicious for hemangioma. A computed tomography guided biopsy was done, which supported the diagnosis. Definitive treatment entailed preoperative angiography and embolization, followed by L3 laminectomy, right L3 pedicle ...

CONCLUSION: Ultrasound could be as sensitive and specific as contrast-enhanced MRI for the diagnosis of subclinical synovitis and tenosynovitis.

AbstractObjectiveThe aim of this study was to investigate cross ‐sectional associations between serum levels of citrate and knee structural changes and cartilage enzymes in patients with knee osteoarthritis (OA).MethodA total of 137 subjects with symptomatic knee OA (mean age 55.0  years, range 34‐74, 84% female) were included. Knee radiography was used to assess knee osteophytes, joint space narrowing (JSN) and radiographic OA assessed by Kellgren‐Lawrence (K‐L) grading system. T2‐weighted fat‐suppressed fast spin echo magnetic resonance imaging (MRI) was used to determine knee cartilage defects, bone mar...

J Knee Surg DOI: 10.1055/s-0039-1700978To improve the long-term outcomes of high tibial osteotomy (HTO) for gonarthritis, many cartilage repair procedures appeared, but their effects were controversial. To evaluate the efficacy of cartilage repair procedures during HTO for gonarthritis, we performed this update meta-analysis. We performed the system retrieval for clinical trials using various databases and then pooled the outcomes of the included studies. Fifteen studies were involved. The pooled results indicated that there were no significant differences in Kellgren and Lawrence (KL) scale (mean difference [MD] =&...

Biologic failures of hip replacement have emerged as an increasing threat to the longevity of the prosthesis. While wear of modern day bearings has been greatly reduced with the advent of cross linked polyethylene, local reaction to metal particles either from the bearing itself or to any of the modular tapers appears to be on the rise. Monitoring of these reactions by the use of plain radiographs or serum markers appears to be insufficient to gauge the gravity of the response.Over the past decade, the use of magnetic resonance imaging (MR) techniques has emerged as the superior noninvasive instrument to assess the extent ...

We compared the assessment of active synovitis in knee osteoarthritis (OA) by utilising superb microvascular imaging (SMI) and conventional power Doppler (cPD) techniques, and then correlated each technique with paients' symptoms, radiographic features and magnetic resonance imaging (MRI)-detected synovitis. A subgroup of participants with symptomatic knee OA underwent dynamic ultrasound assessment for semi-quantitative scores for SMI and cPD in the suprapatellar, medial and lateral parapatellar knee recesses.

DCE-MRI is established for detecting prostate cancer (PCa). However, it requires a gadolinium contrast agent, with potential risks for patients. The application of DIR-MRI is simple and may allow cancer detection without the use of an intravenous contrast agent by differentially nullifying signal from normal and abnormal prostate tissue, creating contrast between the cancer and background normal prostate. In this pilot study we gathered data from DIR-MRI and DCE-MRI of the prostate for an equivalence trial.

Authors: Nakashima H, Kanemura T, Satake K, Ito K, Ishikawa Y, Ouchida J, Segi N, Yamaguchi H, Imagama S Abstract Study Design: Retrospective comparative study. Purpose: We compared clinical and radiographical outcomes after lumbar decompression revision surgery for restenosis by lateral lumbar interbody fusion (LLIF) and posterior lumbar interbody fusion (PLIF). Overview of Literature: Indirect lumbar decompression with LLIF was used to treat degenerative lumbar diseases requiring neural decompression. However, only a few studies have focused on the effectiveness of this technique for restenosis after lumb...

ConclusionsIn conclusion, when compared with current local practice, immediate referral of the patient with AST for MRI following one non-diagnostic ED radiograph is potentially cost-effective in establishing efficient diagnosis of scaphoid fractures. We recommend the implementation of published international guidelines in the investigation of query scaphoid fractures as a pragmatic and cost-effective practice.
