LODOX

  • 文章类型: Journal Article
    低剂量X射线别名Lodox©statscan最初是在南非开发的,用于检测矿山中的走私钻石。稍后,医院创伤部门开始将其用作创伤患者大体病理的筛查工具。该成像系统由于其使用低辐射剂量以及其在13秒内执行前后(头对趾图像)图像的能力而变得流行。轶事证据证实,在Lodox成像后,患者在常规X射线系统上接受了其他区域图像。因此,患者受到额外的电离辐射,漫长的等待时间以及二次放射检查的额外费用。
    这项研究旨在调查南非创伤单位(n=28)中使用Lodox的程度。
    在这项描述性横截面研究中。研究人员邀请了一名来自南非28家使用Lodox的医院的放射技师。
    在20名做出回应的放射技师中,发现大多数医院都向患者推荐其他常规X射线图像(图1);例如,做胸部X光检查.尽管患者接受了与常规X射线系统相似的Lodox成像系统的放射学程序和检查,但还是这样做了。
    Lodox被用于成功的诊断因此,研究者建议制定Lodox的成像方案,以指导患者在进行Lodox扫描后转诊.
    UNASSIGNED: A low dose x-rays alias Lodox© statscan was originally developed in South Africa to detect smuggled diamonds in the mines. Later, hospital trauma units began to use it as a screening tool for gross pathology on trauma patients. This imaging system became popular because of its use of low radiation doses and its ability to perform anterior posterior (head to toe image) image in under 13 seconds. Anecdotal evidence confirms that patients were referred for additional regional images on conventional x-ray systems after Lodox imaging. Thus, patients were subjected to additional ionising radiation, long waiting times as well as additional charges for secondary radiological examinations.
    UNASSIGNED: This research aimed at investigating the extent to which Lodox was used in trauma units (n=28) in South Africa.
    UNASSIGNED: In this descriptive cross-sectional research. researcher invited one radiographer from each of the 28 hospitals in South Africa that were using Lodox.
    UNASSIGNED: Out of twenty radiographers who responded, it was found that most hospitals were referring patients for additional conventional x-ray images (Figure 1); for example, for chest x-rays. This was done despite the patient having undergone radiological procedures and examinations by the Lodox imaging system that was similar to those performed by conventional x-ray systems.
    UNASSIGNED: Lodox was used for a successful diagnosis Thus, researcher recommends an imaging protocol for Lodox to be developed for guiding the referral of patients after the Lodox scanning has been performed.

    BACKGROUND: Increasing global demand for specialized radiological investigations has resulted in delayed or non-reporting of plain trauma radiographs by radiologists. This is particularly true in resource-limited environments, where referring clinicians rely largely on their own radiographic interpretation. A wide accuracy range has been documented for non-radiologist reporting of conventional trauma radiographs. The Lodox Statscan whole-body digital X-ray machine is a relatively new technology that poses unique interpretive challenges. The fracture detection rate of trauma clinicians utilizing this modality has not been determined.
    OBJECTIVE: An audit of the polytrauma fracture detection rate of clinicians evaluating Lodox Statscan bodygrams in two South African public-sector Trauma Units.
    METHODS: A retrospective descriptive study of imaging data of Cape Town Level 1-equivalent public-sector Trauma Units during March-April 2015. Statscan bodygrams acquired for adult polytrauma triage were reviewed and correlated with follow-up imaging and patient records. Missed fractures were stratified by body part, mechanism of injury and ventilatory support. The fracture detection rate was determined with 95% confidence. The Generalised Fischer Exact Test assessed any association between the fracture site and failure of detection. Specialist orthopaedic review assessed the potential need for surgical management of missed fractures.
    RESULTS: 227 patients (male = 193, 85%; mean age: 33 years) were included; 195 fractures were demonstrated on the whole-body triage projections. Lower limb fractures predominated (n = 66, 34%). The fracture detection rate was 89% (95% CI = 86-93%), with the site of fracture associated with failure of detection (p = 0.01). Twelve of 21 undetected fractures (57%) involved the elbow or shoulder girdle. All elbow fractures (n = 3, 100%), more than half the shoulder girdle fractures (9/13,69%) and 12% (15/123) of extremity fractures were undetected. One missed fracture (1/21,4.7%) unequivocally required surgical management, while a further 7 (7/21, 33.3%) could potentially have benefitted from surgery, depending on follow-up imaging findings.
    CONCLUSIONS: This is the first analysis of the accuracy of bodygram polytrauma fracture detection by clinicians. Particular review of the shoulder girdle, elbow and extremities for subtle fractures, in addition to standardized limb positioning, are recommended for improved diagnostic accuracy in this setting. These findings can inform clinician training courses in this domain.

    BACKGROUND: Traumatic brain injury (TBI) is a common diagnosis in the emergency department. Brain computed tomography (CT) has become a standard diagnostic tool with which to examine TBI patients. Conventional X-rays are ineffective for the evaluation of torso or extremity injuries. In the current study, we attempted to establish a diagnostic modality to evaluate systemically initially unconscious patients in the emergency department with a rapid screening technique characterized by sufficient information, low cost and low radiation exposure.
    METHODS: From January 2008 to December 2009, patients with diminished level of consciousness received the Lodox/Statscan for evaluation of extracranial injuries were enrolled in this study. The accuracy of this diagnostic modality in detecting torso or extremity injuries in initially unconscious patients was analyzed by comparing the initial diagnosis (by the Lodox/Statscan) with the final diagnosis (confirmed by torso CT scan or after two weeks of follow-up).
    RESULTS: There were 1,210 patients with TBI whose extracranial injuries were evaluated by the Lodox/Statscan. After excluding intra-abdominal injuries, the overall sensitivity rates of the Lodox/Statscan in diagnosing torso injuries and extremity injuries were 89.7% and 90.2%, respectively. No long bone fracture was missed by the Lodox/Statscan. The sensitivity and specificity of the Lodox/Statscan in diagnosing long bone fractures were both 100%. Most patients with torso injuries that were missed by the Lodox/Statscan could be managed conservatively without further treatment or complications. All of the missed extremity injuries were distal bone fractures.
    CONCLUSIONS: The Lodox/Statscan can provide benefits for surveying extracranial injuries in patients with diminished level of consciousness. The Lodox/Statscan also emits a notably low dose of radiation and appears to be a relatively inexpensive adjunct to screen torso or extremity injuries in TBI patients.
