Outcomes Knowledge May Bias Radiological Decision-making.

RATIONALE AND OBJECTIVES: This research investigates whether an expectation of abnormality and prior knowledge might potentially influence the decision-making of radiologists, and discusses the implications for radiological expert witness testimony. MATERIALS AND METHODS: This study was a web-based perception experiment. A total of 12 board-certified radiologists were asked to interpret 40 adult chest images (20 abnormal) twice and decide if pulmonary lesions were present. Before the first viewing, a general clinical history was given for all images: cough for 3+ weeks. This was called the "defendants read." Two weeks later, the radiologists were asked to view the same dataset (unaware that the dataset was unchanged). For this reading, the radiologists were given the following information for all images: "These images were reported normal but all of these patients have a lung tumour diagnosed on a subsequent radiograph 6 months later." They were also given the lobar location of the newly diagnosed tumor. This was called the "expert witness read." RESULTS: There was a significant difference in location-based sensitivity (W = -45, P = 0.02) between the two conditions with nodule detection increasing under the second condition. Specificity increased outside the lobe of interest (W = 727, P = < 0.0001) and decreased within the lobe of interest (W = -237, P = 0.03) significantly in the "expert witness" read. Case-based sensitivity and case-based specificity were unaffected. CONCLUSIONS: This study showed evidence that increased clinical information affects the performance of radiologists. This effect may bias expert witnesses in radiological malpractice litigation.

Jejunal diverticulitis ascending to the duodenum as a rare cause of acute abdomen.

We present the case of a 73 year-old Caucasian male with acute abdominal pain, peritonism and vomiting. Due to the severity of symptoms a CT examination of the abdomen was performed. The scans revealed multiple jejunal diverticula, wall thickening of the duodenum and jejunum, and free peritoneal fluid. No clear signs of mesenteric infarction, free abdominal air or abscess formation were seen. An additional exploratory laparotomy was conducted to confirm the CT findings and rule out the need for resection of small bowel. Since the results were matching, conservative therapy was scheduled and the patient recovered well. Jejunal diverticulitis is a rare cause of acute abdomen, however has to be considered as a differential diagnosis to more common entities. It usually stays localized, while in our case the inflammation ascended to the duodenum. CT is the modality of choice to diagnose and rule out potentially life threatening complications.

Rare case of a chondrosarcoma of the mandible in a child.

Chondrosarcoma of the mandible is rare, especially in children. The available literature consists mostly of a few case reports which are partly integrated in small studies. Growing this small pool of literature is helpful in solidifying knowledge about this disease and facilitating appropriate treatment for children. Therefore, we present such a case in a 12-year-old boy, exhibit comprehensive and relevant information concerning this entity, and discuss our findings in the context of other publications.

Atypical Osteomyelitis Caused by Mycobacterium chelonae-A Multimodal Imaging Approach.

We present an unusual case of a biopsy-proven Mycobacterium chelonae infection (MCI) of skin and soft tissue, which led to osteomyelitis in a 55-year-old Caucasian male. We provide clinical data and discussion about MCI and its diagnostic workup and demonstrate comprehensive imaging findings, including clinical pictures, radiographs, three-phase bone scintigraphy, and combined SPECT/CT findings of this entity, which have not yet been presented in the medical literature.

Smartphones, tablets and mobile applications for radiology.

BACKGROUND: Smartphones are phone devices that may also be used for browsing, navigation and running smaller computer programs called applications. One may consider them as compact personal computers which are primarily to be used for making phone calls. Tablets or "tablet PCs" are fully functioning standalone computers the size of a thin LCD monitor that use the screen itself for control and data input. Both of these devices may be categorized based on the mobile operating system that they use. The aim of this study is to illustrate how smartphones and tablets can be used by diagnostic imaging professionals, radiographers and residents, and to introduce relevant applications that are available for their field. MATERIALS AND METHODS: A search was performed on iTunes, Android Market, Blackberry App World, and Windows Phone Marketplace for mobile applications pertinent to the field of diagnostic imaging. The following terms were applied for the search strategy: (1) radiology, (2) X-ray, (3) ultrasound, (4) MRI, (5) CT, (6) radiographer, (7) nuclear medicine. Two radiologists and one radiology resident reviewed the results. Our review was limited to english-language software. Additional applications were identified by reviewing the list of similar software provided in the description of each application. We downloaded and installed all applications that appeared relevant to an appropriate mobile phone or tablet device. RESULTS: We identified and reviewed a total of 102 applications. We ruled out 1 non-English application and 20 other applications that were created for entertainment purposes. Thus our final list includes 81 applications in the following five categories: diagnostic reading, decision support applications, medical books, interactive encyclopedias, and journal reading programs. CONCLUSION: Smartphones and tablets offer new opportunities for diagnostic imaging practitioners; these easy-to-use devices equipped with excellent display may be used for diagnostic reading, reference, learning, consultation, and for communication with patients.

Fluorodeoxyglucose-positron-emission tomography findings in mantle cell lymphoma.

OBJECTIVE: Mantle cell lymphoma (MCL) is an aggressive type of non-Hodgkin lymphoma with a propensity for extranodal involvement. The role of fluorodeoxyglucose (FDG)-positron emission tomography (PET) imaging in common types of lymphoma has been well-established. However, there is limited information in the literature about the utility of FDG-PET imaging in patients who have MCL. The aim of this study was to determine the role of FDG-PET imaging in assessment of disease activity in MCL compared with conventional imaging techniques such as computerized tomography/magnetic resonance imaging (CT/MRI). METHODS: FDG-PET images of 20 patients with MCL who were referred to our center for assessment of extent of disease were reviewed retrospectively. The FDG-PET findings were compared with those of CT/MRI and were correlated with clinical information, histopathology, and outcome. RESULTS: The diagnostic sensitivity for PET was 90% (17/19), and specificity was 100% (1/1). For CT/MRI, the sensitivity was 87% (14/16) and specificity was 50% (2/4). PET was better than CT/MRI in detecting nodal involvement. With respect to extranodal involvement, PET detected more cases of spleen involvement than CT/MRI. PET was equivalent to conventional imaging in detecting bowel involvement. CONCLUSIONS: PET imaging has a high sensitivity in detecting both nodal and extranodal involvement in patients who have MCL. Based on the available data in patients who had other subtypes of non-Hodgkin lymphoma, the specificity of PET also appears to be superior to anatomic imaging techniques. FDG-PET imaging may prove to be the single most effective method for detection.
