Modular extension of the ACR-NEMA DICOM standard to support new diagnostic imaging modalities and services

IntroductionThe optimal diagnostic imaging strategy for fracture-related infection (FRI) remains to be established. In this prospective study, the three commonly used advanced imaging techniques for diagnosing FRI will be compared. Primary endpoints are (1) determining the overall diagnostic performances of white blood cell (WBC) scintigraphy, fluorodeoxyglucose positron emission tomography (FDG-PET) and magnetic resonance imaging (MRI) in patients with suspected FRI and (2) establishing the most accurate imaging strategy for diagnosing FRI.Methods and analysisThis study is a non-randomised, partially blinded, prospective cohort study involving two level 1 trauma centres in The Netherlands. All adult patients who require advanced medical imaging for suspected FRI are eligible for inclusion. Patients will undergo all three investigational imaging procedures (WBC scintigraphy, FDG-PET and MRI) within a time frame of 14 days after inclusion. The reference standard will be the result of at least five intraoperative sampled microbiology cultures, or, in case of no surgery, the clinical presence or absence of infection at 1 year follow-up. Initially, the results of all three imaging modalities will be available to the treating team as per local protocol. At a later time point, all scans will be centrally reassessed by nuclear medicine physicians and radiologists who are blinded for the identity of the patients and their clinical outcome. The discriminative ability of the imaging modalities will be quantified by several measures of diagnostic accuracy.Ethics and disseminationApproval of the study by the Institutional Review Board has been obtained prior to the start of this study. The results of this trial will be disseminated by publication of peer-reviewed manuscripts, presentation in abstract form at scientific meetings and data sharing with other investigators through academically established means.Trial registration numberThe IFI trial is registered in the Netherlands Trial Register (NTR7490).

The awareness, theoretical and practical knowledge of radiography, ultrasonography, magnetic resonance imaging (MRI), computed tomography (CT), nuclear medical imaging (NMI) and thermography were accessed among veterinary surgeons teaching in veterinary schools in Nigeria, using a structured questionnaire. Respondents were grouped into five depending on their years of experience post-graduation. These were Group A (0-5 years), Group B (6-10 years), Group C (11-15 years) Group D (16-20 years) and Group E (> 20 years). The result of the awareness of radiography as a diagnostic imaging modality in veterinary practice was not dependent on the years of research experience. A 100 % of respondents in Group A were aware that ultrasonography is indicated in veterinary practice; while only 96.67 % were aware that radiography is so indicated. There was a gradual decline in the awareness of CT compared to radiography and ultrasonography. There was low awareness of the application of MRI, NMI and thermography in veterinary practice by all respondents irrespective of their years of experience. There was a decline in the degree of theoretical knowledge with advancement in the technique. The variation in the mere observation of the practical demonstration of radiography was related to years of research experience, with the exception of Group D. Group E recorded the highest positive response to practical knowledge of all the diagnostic imaging modalities. There was a remarkable drop in the practical knowledge of CT, MRI, NMI and thermography, compared to radiography and ultrasonography in each of the study groups. Only 1 veterinary school had a CT scanning machine, and none had an MRI unit, a gamma camera or a thermographic camera. Only 4 veterinary schools taught MRI. No veterinary school taught NMI and thermography. Appropriate recommendations were made. Keywords: CT, MRI, NMI, Radiography, Thermography, Ultrasonography

Imaging Modalities

Cervical spondylosis is a spectrum of pathology presenting as neck pain, radiculopathy, and myelopathy or all in combination. Diagnostic imaging is essential to diagnosis and preoperative planning. We discuss the modalities of imaging in common practice. We examine the use of imaging to differentiate among central, subarticular, and lateral stenosis and in the assessment of myelopathy.
