Ultrasound, computed tomography or magnetic resonance imaging - which is preferred for acute appendicitis in children? A Meta-analysis
Abstract
Background
There is no established consensus about the relative accuracies of US, CT and MRI in childhood appendicitis.
Objective
To compare, through meta-analysis, the accuracies of US, CT and MRI for clinically suspected acute appendicitis in children.
Materials and methods
PubMed, Embase, Web of Science and the Cochrane Library were searched. After study selection, data extraction and quality assessment, the sensitivity, specificity and the area under the curve of summary receiver operating characteristic were calculated and compared.
Results
Twenty-seven articles including 29 studies met the inclusion criteria, including 19 studies (9,170 patients) of US, 6 studies (928 patients) of CT and 4 studies (990 patients) of MRI. The analysis showed that the area under the receiver operator characteristics curve of MRI (0.995) was a little higher than that of US (0.987) and CT (0.982; P > 0.05).
Conclusion
US, CT and MRI have high diagnostic accuracies of clinically suspected acute appendicitis in children overall with no significant difference.

Estimated cumulative radiation dose received by diagnostic imaging during staging and treatment of operable Ewing sarcoma 2005–2012
Abstract
Background
Patients with Ewing sarcoma are subject to various diagnostic procedures that incur exposure to ionising radiation.
Objective
To estimate the radiation doses received from all radiologic and nuclear imaging episodes during diagnosis and treatment, and to determine whether 18F-fluorodeoxyglucose positron emission tomography – computed tomography (18F-FDG PET-CT) is a major contributor of radiation.
Materials and methods
Twenty Ewing sarcoma patients diagnosed in Norway in 2005–2012 met the inclusion criteria (age <30 years, operable disease, uncomplicated chemotherapy and surgery, no metastasis or residual disease within a year of diagnosis). Radiation doses from all imaging during the first year were calculated for each patient.
Results
The mean estimated cumulative radiation dose for all patients was 34 mSv (range: 6–70), radiography accounting for 3 mSv (range: 0.2-12), CT for 13 mSv (range: 2–28) and nuclear medicine for 18 mSv (range: 2–47). For the patients examined with PET-CT, the mean estimated cumulative effective dose was 38 mSv, of which PET-CT accounted for 14 mSv (37%).
Conclusion
There was large variation in number and type of examinations performed and also in estimated cumulative radiation dose. The mean radiation dose for patients examined with PET-CT was 23% higher than for patients not examined with PET-CT.

Imaging in the diagnosis of pediatric urolithiasis
Abstract
Pediatric urolithiasis is an important and increasingly prevalent cause of pediatric morbidity and hospital admission. Ultrasound (US) is the recommended primary imaging modality for suspected urolithiasis in children. There is, however, widespread use of CT as a first-line study for abdominal pain in many institutions involved in pediatric care. The objective of this review is to outline state-of-the-art imaging modalities and methods for diagnosing urolithiasis in children. The pediatric radiologist plays a key role in ensuring that the appropriate imaging modality is performed in the setting of suspected pediatric urolithiasis. Our proposed imaging algorithm starts with US, and describes the optimal technique and indications for the use of CT. We emphasize the importance of improved communication with a greater collaborative approach between pediatric and general radiology departments so children undergo the appropriate imaging evaluation.
