Objectives: Pelvis radiographs are usually acquired supine despite standing imaging reflecting functional anatomy. We compared supine and erect radiographic examinations for anatomical features, radiation dose and image quality. Methods: 60 patients underwent pelvis radiography in both supine and erect positions at the same examination appointment. Measures of body mass index and sagittal diameter were obtained. Images were evaluated using visual grading analysis and pelvic tilt was compared. Dose–area product values were recorded and inputted into the CalDose_X software to estimate effective dose (ED). The CalDose_X software allowed comparisons using data from the erect and supine sex-specific phantoms (MAX06 & FAX06). Results: Patient sagittal diameter was greater on standing with an average 20.6% increase at the iliac crest (median 30.0, interquartile range [26.0 to 34.0] cm), in comparison to the supine position [24.0 (22.3 to 28.0) cm; p < 0.001]. 57 (95%) patients had posterior pelvic tilt on weight-bearing. Erect image quality was significantly decreased with median image quality scores of 78% (69 to 85) compared to 87% for the supine position [81 to 91] (p < 0.001). In the erect position, the ED was 47% higher [0.17 (0.13 to 0.33) mSv vs 0.12 (0.08 to 0.18) mSv (p < 0.001)], influenced by the increased sagittal diameter. 42 (70%) patients preferred the standing examination. Conclusion: Patient diameter and pelvic tilt were altered on weightbearing. Erect images demonstrated an overall decrease in image quality with a higher radiation dose. Optimal acquisition parameters are required for erect pelvis radiography as the supine technique is not directly transferable.

The initial reports on radiologic examinations in 618 consecutive patients with midfacial injuries were compared with the final clinical diagnoses. Alcohol had to some degree been imbibed by 31 per cent of the patients. Influence of alcohol was 3 times more common outside than within office hours. Radiographic analysis included estimation of blurring, errors in straightness, angulation, beam centering and limitation. Image quality was scored as visibility of ‘the imaginary lines of bony continuity’. There was no statistically significant correlation between the degree of inebriety and image quality or diagnostic performance with the radiographic technique used, with the patient supine. There is no need to postpone midfacial radiography in inebriate patients.

Background Diagnosis and treatment of patellofemoral disorders including osteoarthritis are currently often based on imaging and clinical assessment with patients in the supine position. Purpose To evaluate differences in patellar position in the trochlear groove and to assess the detection of medial and lateral patellofemoral (PF) osteoarthritis (OA) on axial radiographs in supine and standing positions, respectively. Material and Methods Thirty-five women and 23 men (mean age, 56 years; age range, 18–87 years) referred for routine radiographic examinations of the knees were included. Axial radiographs of the PF joint in both supine non-weight-bearing and standing weight-bearing position in 30° knee flexion were obtained of 111 knees. Measurements performed on the radiographs: patellar tilt, patellar displacement, joint space width, and grade of OA according to Ahlbäck. Results From supine to standing position the patella moved medially and medial joint space width and lateral patellar tilt angle decreased ( P < 0.0001 for the three measured parameters). In the standing position, medial PF OA was observed in 19 knees compared to three knees in the supine position. Fourteen knees had lateral PF OA with almost unchanged grade of OA irrespective of position. Conclusion In weight-bearing positions, the patella is positioned medially in the trochlear groove compared to supine non-weight-bearing positions. Therefore, this study suggests that the common occurrence of medial PF OA can generally not be detected on axial radiographs in supine non-weight-bearing positions and confirms the importance of imaging the PF joint in standing weight-bearing positions.

ABSTRACT Objective: To evaluate the importance of radiography in the orthostatic position in the initial assessment of patients with thoracolumbar transition fractures and whether this image changes the surgical indication. Methods: Medical records and imaging tests of patients treated for thoracolumbar transition fractures from June 2018 to June 2019 were evaluated. Trauma patients between 18 and 60 years of age with fractures of T10 to L3 who had been indicated for conservative treatment were included. Cases of fractures considered unstable were excluded. Radiographs were taken with the patient in the supine position (supine X-ray), computed tomography (CT), and orthostatic radiography (orthostatic X-ray). Segmental kyphosis and degree of wedging were evaluated. The measurements were compared using the Wilcoxon test. The McNemar test was used to assess changes in conduct according to the criteria for surgical indication (kyphosis ≥ 25 ° and wedging ≥ 50%). Results: Fifty patients were evaluated, nine of whom (18%) were indicated for a change of conduct according to the orthostatic examinations and were submitted to surgical treatment. Vertebral kyphosis increased by 40.6% (p <0.001). The wedging increased by 25.62% (p <0.0001). Conclusion: Eighteen percent of the total number of patients who did not present instability criteria in radiographs in the supine position satisfied at least one of these criteria when the orthostatic X-ray was performed. Level of evidence 3B; Retrospective case series study.

From a series of patients undergoing routine radiographic examination, 112 temporal bones with a high jugular fossa were selected. Among these, 43 jugular bulb diverticula were found. The structures affected by a high fossa or diverticulum were recorded and correlated to the clinical symptoms of the patient. The vestibule was suspected to be affected in five patients. Two of these patients had tinnitus and vertigo, and three had hearing loss. In one of the latter the hearing loss was most marked in the supine position. The cochlea was close to the fossa in three patients, all of whom had tinnitus. Four patients had a defect of the posterior semicircular canal. One of them lost his hearing after a severe fit of coughing, became unsteady and showed signs of a fistula. The internal acoustic meatus and the mastoid portion of the facial canal were affected in two and four patients, respectively, who had no recorded symptoms. Twelve of 34 patients with Menière's disease and a high jugular fossa on the side of the diseased ear had a dehiscence of the vestibular aqueduct caused by the fossa or diverticulum, compared with nine of 58 patients in the unselected material. For comparison and demonstration of topographic relationships, 58 casts of unselected radiographed temporal bone specimens with high jugular fossae or diverticula were investigated. In patients with a high jugular fossa or jugular bulb diverticulum, tomographic assessment may be of value.

INTRODUCTION Acute osteoporotic vertebral compression fractures are common and usually managed conservatively. However, a significant number will remain symptomatic, causing significant pain with considerable associated morbidity and mortality. These fractures can be effectively treated with cement augmentation. However, it is impossible to distinguish between an acute and a chronic healed fracture on plain radiographs. The definitive investigation is a magnetic resonance scan. The aim of this paper is to describe and evaluate two new clinical signs to help in the diagnosis of symptomatic fractures. A prospective study of 83 patients with suspected acute osteoporotic vertebral compression fractures was carried out. All patients had a full clinical assessment, which included closed-fist percussion of their spine and asking the patient to lie supine on the examination couch. All patients had a MRI scan. RESULTS The closed-fist percussion sign had a sensitivity of 87.5% and a specificity of 90%. The supine sign had a sensitivi-’ of 81.25% and a specificity of 93.33%. CONCLUSIONS These tests will enable the practitioner to predict more accurately which patients have an acute fracture, guiding referral for further imaging.

A radiologic investigation was performed in 26 patients subjected to colectomy, mucosal proctectomy and endorectal ileo-anal anastomosis after the creation of an ileal reservoir. The patients had suffered from ulcerative colitis or familial polyposis. The reservoir and its efferent leg was best demonstrated by contrast enema. The size and position of the reservoir and the efferent leg was demonstrated, and stenoses, abscesses and fistulae could be identified. Examination of the small bowel with a contrast medium showed slight dilatation of the ileum orally to the reservoir in all instances and one patient had a stenosis at the junction of the afferent leg of the reservoir. Erect and supine projections of the abdomen showed gas in the intestine and fluid levels in the reservoir. These radiographic findings should not be confused with ileus or pelvic abscess. Radiology was of great value in disclosing postoperative complications. References

AbstractThis study was aimed to investigate the role of anatomic variations in patellofemoral alignment in patients with or without Osgood-Schlatter disease (OSD) and to determine the potential anatomic risk factors that may play role in the etiology. This prospective observational case-control study was conducted on two groups of adolescent patients. Group 1 comprised patients who were diagnosed as having OSD and group 2 consisted of an equal number of age-matched patients who presented to the outpatient clinic with traumatic knee injury and underwent knee radiographic examination but without a diagnosis of OSD. Age, height, weight, body mass index (BMI), dominant side, and level of sporting activity were recorded. Quadriceps (Q) angles were measured using a long-arm goniometer with patients lying in the supine position with their knees in full extension and contracting the Q muscles. On anteroposterior, lateral knee, and tangential patella (Merchant and Laurin views) radiographs, the following measurements were performed: Insall–Salvati (IS), Caton–Deschamps (CD), and Blackburne–Peel (BP) indexes, congruence angles, lateral patellofemoral angles, sulcus angles, and patella type according to Grelsamer's morphology classification. Both groups were similar in respect of age (p = 0.160), sex (p = 0.311), height (p = 0.326), weight (p = 0.596), BMI (p = 0.153), and dominancy (p = 0.500). The rate of patients engaged in sports activities was significantly greater in the OSD group (p = 0.003). No significant difference was determined between the groups in respect to IS index, CD index, BP index, sulcus angle, lateral patellofemoral angle, and congruence angle (p–values: 0.358, 0.995, 0.912, 0.802, 1.000, and 0.907, respectively). The mean Q angle was measured as 15.6 ± 2.2 degrees in the OSD group and 14.3 ± 2.5 degrees in the control group (p = 0.014). Despite the difference being statistically significant, it was clinically insignificant because the difference was only 1.3 degrees. The principle etiologic factor seems to be increased physical activity rather than subtle variations is patellofemoral anatomy and alignment of extensor mechanism.

Introduction: Acute abdomen might indicate a progressive intra-abdominal condition that is threatening to life or capable of causing severe morbidity. A good history, thorough clinical examination, laboratory investigations and imaging studies is necessary in order to arrive at a correct diagnosis. The aim of our study was to compare the diagnostic yield of traditional three-view abdominal x-ray series (upright chest x-ray, supine and upright abdominal x-rays) with that of ultrasound in patients presenting with non traumatic acute abdominal surgical pain. Methods: This prospective study was conducted between February and July 2010 on 65 consecutive patients. Critically ill patients, pregnant ladies, patient with trauma abdomen, acute abdomen due to gynaecological pathologies were excluded from our study. Detail abdominal ultrasound was done. After ultrasound traditional three-views acute abdominal x-ray series (AAS) were taken. Final diagnosis was made on the basis of operative findings/therapeutic response/ histopathological/ laboratory findings. Finally, accuracy of clinical diagnosis, plain film and ultrasound in evaluation of acute abdomen was determined. Results: Ultrasound yielded an overall sensitivity and specificity of 78.7% and 84.6.6% respectively. The AAS interpretations yielded an overall sensitivity and specificity of 23.4% and 38.40% respectively. Conclusion: Plain x ray is less sensitive in the evaluation of nontraumatic acute abdomen so it should be used together with ultrasound abdomen in order to arrive at a correct diagnosis.

Hospitalized patients in a critical care environment are at risk for adverse intra-abdominal events involving bowel, solid organs, and vasculature. For assessment of hospitalized patients with abdominal pain, a thorough history and physical examination should precede indicated laboratory testing and imaging studies. One expedient means of evaluation is abdominal radiography. In very ill patients, it can be performed at the bedside. Because of its ready availability and occasional definitive diagnostic information, however, abdominal radiography often is the first imaging study performed. Ideally, a supine frontal image is supplemented with an upright or left lateral decubitus (left-side down) frontal view.
