Plain Radiography In Diagnosis Research Articles

Diagnostic accuracy of ultrasound in upper and lower extremity long bone fractures of emergency department trauma patients

BackgroundLong bone fractures are common injuries caused by trauma. Some studies have demonstrated that ultrasound has a high sensitivity and specificity in the diagnosis of upper and lower extremity long bone fractures.ObjectiveThe aim of this study was to determine the accuracy of ultrasound compared with plain radiography in diagnosis of upper and lower extremity long bone fractures in traumatic patients.MethodsThis cross-sectional study assessed 100 patients admitted to the emergency department of Imam Khomeini Hospital, Ahvaz, Iran with trauma to the upper and lower extremities, from September 2014 through October 2015. In all patients, first ultrasound and then standard plain radiography for the upper and lower limb was performed. Data were analyzed by SPSS version 21 to determine the specificity and sensitivity.ResultsThe mean age of patients with upper and lower limb trauma were 31.43±12.32 years and 29.63±5.89 years, respectively. Radius fracture was the most frequent compared to other fractures (27%). Sensitivity, specificity, positive predicted value, and negative predicted value of ultrasound compared with plain radiography in the diagnosis of upper extremity long bones were 95.3%, 87.7%, 87.2% and 96.2%, respectively, and the highest accuracy was observed in left arm fractures (100%). Tibia and fibula fractures were the most frequent types compared to other fractures (89.2%). Sensitivity, specificity, PPV and NPV of ultrasound compared with plain radiography in the diagnosis of upper extremity long bone fractures were 98.6%, 83%, 65.4% and 87.1%, respectively, and the highest accuracy was observed in men, lower ages and femoral fractures.ConclusionThe results of this study showed that ultrasound compared with plain radiography has a high accuracy in the diagnosis of upper and lower extremity long bone fractures.

Appendicitis in the era of ultrasound: Are plain radiographs still useful?

We reviewed plain radiographs of 215 pediatric patients with surgically proven appendicitis to study the value of plain radiography for diagnosis.

Reversible ischaemic colitis due to venous or small vessel occlusion. A diagnosis by plain abdominal radiography.

Summary A case of reversible ischaemic colitis is described. Diagnosis was achieved by plain abdominal radiography, and confirmed by contrast radiography. Ischaemic disease resulted from small vessel or venous occlusion. The importance of plain radiography in diagnosis and serial barium enemas in assessment of progress is stressed. The differential diagnosis of radiographic findings is discussed.
