Bone metastases

Plain radiography is used in the incidental detection of lesions, targeted assessment of bones in patients who have indeterminate abnormalities detected at bone scintigraphy, and qualitative assessment of bone loss in patients with known malignant disease as a predictor of future fracture risk.
Radiation Safety in Chiropractic Radiography
Published in Russell L. Wilson, Chiropractic Radiography and Quality Assurance Handbook, 2020
Radiographic procedures must be authorized by a clinician and have clinical reasons for their performance. The clinical history of the patient shall be monitored by radiology staff. The clinical benefit of the radiographic study must outweigh the risks of exposure to ionizing radiation.
Simulated Practice
Published in Christopher M. Hayre, William A. S. Cox, General Radiography, 2020
Learning draws upon all five senses: touch, sight, sound, taste, and smell. Within a radiography setting, each of these are used to inform judgement, behavior, practice, and to support the patients during imaging procedures. Integrating the use of each sense increases the fidelity, allowing individuals to behave as they would in a real situation improving the transfer of skills and knowledge from simulation to practice.

Our protocol requires both a full CT scan of the entire leg and a biplanar standing radiograph, which, depending on the clinic, is not always part of the standard protocol. The acquisition of standing radiographs is part of the standard workflow everywhere, and highly specialized centers use the EOS system to significantly reduce the radiation exposure and acquire biplanar images in a 90° angle. The proposed registration approach could also be implemented for standard uniplanar full-leg standing radiography in order to align the 3D models to the standing position in the frontal plane. Compared to radiography, the acquisition of CT scans exposes the patient to more radiation and has to be considered carefully. Therefore, our CT protocol skips the shaft regions of femur and tibia. Technological developments, such as ultra low-dose CT or bone MRI, could be used in the future to further reduce the radiation dose.

A total of 265 responses were received, however, only 255 responses were deemed complete and included in the analysis. Their sociodemographic characteristics were shown in Table 1. The radiographers were fairly distributed across the six geopolitical zones of Nigeria. They were mainly male radiographers (n = 196, 76.9%), aged between 30 and 39 years (n = 110, 43.1%), who held a Bachelor of Radiography (n = 160, 62.7%) and had practised within one decade after graduation (n = 171, 67.1%). Figures 1 and 2 show the participants’ sex distribution and professional expertise, respectively. Participants were above-average in their knowledge of COVID-19 pathology (82.46 ± 8.67%), knowledge of the prevention and treatment (93.43 ± 7.11%), attitude towards clinical practice (74.11 ± 11.61%) and adherence to standard precautions during the COVID-19 pandemic (56.08 ± 18.56%). Table 2 shows the participants’ attitudes towards clinical practice during the pandemic. More than half of the participants (58.5%) were willing to provide clinical services during the pandemic.

Plain radiographs are frequently the first-line investigation in patients presenting with pain but often, regardless of X-ray findings, further imaging is warranted based on clinical findings. X-rays in CNO may be normal but may show signs of aggressive pathology, including sclerosis, lysis, and new bone formation [17]. Estimates of the sensitivity of plain radiographs in CNO/CRMO varies from 31–77% [10,13], and, in cases where there are characteristic clinical symptoms and characteristic X-ray changes (such as medial clavicle expansion and sclerosis), further imaging to confirm the diagnosis may not be necessary [72]. CT is rarely used investigation of CNO/CRMO but may have a role in excluding other pathologies, such as osteoid osteoma, and in directing bone biopsy. Ultrasound is not the method of choice to detect bone lesions. However, it may be used initially to exclude extraosseous abscesses, to screen for joint effusion and synovitis in the presence of joint swelling, to image periosteal irregularities, or during the diagnostic workup while excluding differential diagnoses (such as screening of the abdomen for organomegaly or intraabdominal fluid) [17].
