“…Our study did not allow us to retrieve in real time, comparison studies in a practical manner as our iPads could not be wirelessly linked to the PACS network. The remaining nine minor discrepant findings were correctly diagnosed by at least one reader, which again suggests that it was not necessarily hardware issues that impeded the perception of the abnormalities, but could be attributed to the variability in reporting by the participating radiologists [18]. The user survey results showed that the iPad and the OsiriX application scored favorably for ease and speed of image retrieval, portability, screen size, and user interface.…”

“…However, none of these errors were committed by all three readers, and in all cases, the correct diagnosis was achieved by two of the other readers. This would imply that the discrepant readings were likely due to reader factors such as inherent variability in interobserver interpretation rather than hardware or software limitations with the iPad and OsiriX [18]. In two cases of the undetected focal intracranial hemorrhages and one case of a missed acute cerebellar infarct on MRI, the abnormalities were part of a broader spectrum of similar findings and although in themselves clinically significant findings, would not have impacted immediate management.…”

The iPad Tablet Computer for Mobile On-Call Radiology Diagnosis? Auditing Discrepancy in CT and MRI Reporting

Tablet computers such as the iPad, which have a large format, improved graphic display resolution and a touch screen interface, may have an advantage compared to existing mobile devices such as smartphones and laptops for viewing radiological images. We assessed their potential for emergency radiology teleconsultation by reviewing multi-image CT and MRI studies on iPad tablet computers compared to Picture Archival and Communication Systems (PACS) workstations. Annonymised DICOM images of 79 CT and nine MRI studies comprising a range of common on-call conditions, reported on full-featured diagnostic PACS workstation by one Reporting Radiologist, were transferred from PACS to three iPad tablet computers running OsiriX HD v 2.02 DICOM software and viewed independently by three reviewing radiologists. Structured documentation was made of major findings (primary diagnosis or other clinically important findings), minor findings (incidental findings), and user feedback. Two hundred and sixty four readings (88 studies read by three reviewing radiologists) were compared, with 3.4 % (nine of 264) major discrepancies and 5.6 % (15 of 264) minor discrepancies. All reviewing radiologists reported favorable user experience but noted issues with software stability and limitations of image manipulation tools. Our results suggest that emergency conditions commonly encountered on CT and MRI can be diagnosed using tablet computers with good agreement with dedicated PACS workstations. Shortcomings in software and application design should be addressed if the potential of tablet computers for mobile teleradiology is to be fully realized.

“…To assess the potential clinical impact of the differences in differential diagnoses between the observers and the reference diagnosis established from the board certified radiologists' interpretation, a scoring system was generated to grade the levels of discrepancy between observers (ABUJUDEH et al, 2010). The scoring system, definitions and examples of the levels of discrepancy are provided in Table 2.…”

Interpretation of pulmonary radiographs is one of the most difficult aspects of radiology and interobserver variability is high. The aim of this study was to assess variations in interpretation of pulmonary pathology amongst Brazilian veterinarians with different levels of training and experience, using the interpretation by American board-certified radiologists as a reference. We identified areas where interpretation is particularly challenging. Sixty digital canine thoracic radiographic examinations were interpreted by four groups of three Brazilian observers, each group being defined by different levels of training and experience. The radiographic findings of the 4 groups of observers in the study were compared to a reference interpretation established from the findings of three ACVR board-certified radiologists. The degree of discrepancy for each list between each group and the reference interpretation was assessed according to a three-level scoring system: no discrepancy, minor discrepancy, or major discrepancy. Data was analyzed using a Kappa and Cochran-Mantel-Haenszel tests. Brazilian veterinarians with the most training and experience showed the least interobserver variation and best performance when compared to the reference interpretation, followed by those with practical training, but with little work experience in professional practice. The radiographic patterns that were associated with the highest interobserver variability were the vascular, unstructured interstitial and bronchial patterns. Interobserver major discrepancies occurred in all groups, but is more evident in groups with the least training (44.4%) and the general practitioners (26.7%) group. It can be concluded that training positively influences the accuracy of radiographic interpretation and is recommended to reduce erroneous diagnoses.

O objetivo desse estudo é detectar as variações de interpretação entre radiologistas brasileiros em diferentes graus de treinamento e experiência, utilizando a interpretação de consenso feito por radiologistas americanos certificados pelo Colégio Americano de Radiologia Veterinária. Na tentativa de identificar os desafios e as particularidades dessa interpretação. Sessenta exames radiográficos digitais do tórax de cães foram interpretados por quatro grupos de observadores com diferentes graus de treinamento em leitura de exames radiográficos. O grau de discrepância entre as observadores foram comparados seguindo um escore com três subclassificações: sem discrepância, discrepância leve e maiores discrepâncias. Para análise dos dados os métodos estatísticos utilizados foram o Kappa e Cochran-Mantel-Haenszel. Os veterinários brasileiros com maior grau de treinamento e experiência foram o que apresentaram menores variações de interpretação quando comparado aos dados d...

Pitfalls in Imaging of Female Pelvic Masses

Purpose of Review The purpose of this review is to highlight potential magnetic resonance (MR) imaging pitfalls that may mask and simulate ovarian cancer. Recent Findings MR imaging is the standard method for evaluating female pelvic masses of indeterminate origin, especially sonographically indeterminate adnexal masses. To define the correct origin and nature of a pelvic mass has an enormous clinical impact, namely in females of child-bearing age. This is particularly true in adnexal lesions. Ovarian cancer usually requires a cytoreductive surgery in a specialized oncological centre. In contrast, a benign ovarian lesion may be treated by simple resection in a general hospital. To help preventing diagnostic errors and in order to guide appropriate therapeutic management, radiologists should be aware of potential MR pitfalls that may mask and simulate ovarian cancer. Summary The first section of this article will describe the MR imaging protocol that authors perform in their oncological centre, highlighting how imaging techniques can be optimized in order to reduce pitfalls in the characterization of an indeterminate pelvic mass.In the next section, authors will revise the main anatomic and organ-specific signs that may allow the radiologist to determine the ovarian origin of a pelvic mass. Finally, benign gynaecological masses that may simulate ovarian cancer in a non-emergency setting will be discussed, with emphasis on features that may provide important clues to their diagnosis.
