Accuracy of laser-scanned models compared to plaster models and cone-beam computed tomography.

Conclusions: In conclusion, plaster models, CBCT models, and laser-scanned models are three different diagnostic records, each with its own advantages and disadvantages. The present results showed that the laser-scanned models are highly accurate to plaster models and CBCT scans. This gives general clinicians an alternative to take into consideration the advantages of laser-scanned models over plaster models and CBCT reconstructions.

Cellular Analytics, a biotechnology company in Ontario, Canada, has unveiled a novel liquid biopsy test for mesothelioma that could lead to more effective management of this rare cancer. The test has the potential to produce a much-earlier diagnosis of disease and the ability to personalize treatment and better predict a patient’s response to specific therapies. “We could change completely how this disease is viewed,” Dr. Brent Zanke, a specialist in diagnostic oncology and chief executive officer of Cellular Analytics, told The Mesothelioma Center at Asbestos.com. “It’s a proactive way to get...

Key Points• Novel coronavirus (COVID-19)-infected pneumonia usually manifests as bilateral ground-glass opacities in the lung periphery on chest CT scans.• Role of radiologists includes not only early detection of lung abnormality, but also suggestion of disease severity, potential progression to acute respiratory distress syndrome, and possible bacterial co-infection in hospitalized patients.

ConclusionThe vessel-specific MCP myocardial perfusion territory assignment technique more accurately quantifies LCA and RCA perfusion territories as compared with the current standard AHA 17-segment model. Therefore, it can potentially provide a more comprehensive and patient-specific evaluation of coronary artery disease.Key Points• The minimum cost path (MCP) technique accurately determines left and right coronary artery perfusion territories, as compared with the American Heart Association 17-segment (AHA) model.• The minimum cost path (MCP) technique could be applied to cardiac computed-tomography angiograph...

ConclusionsThe variability of radiocholine uptake in adrenal glands depends probably on overall body metabolism and hypophyseal function expressed by statistically significant correlation with liver and pituitary gland uptake.Predominant focal or mixed with focal areas uptake patterns on positron emission tomography in normal in computed tomography adrenal glands should be assessed with caution to avoid a diagnostic mistake.

This study aimed to analyse the features of lymphadenopathy and estimate the role of imaging methods, including computed tomography (CT) and positron emission tomography-CT (PET/CT), in the diagnosis of lymphadenopathy in patients with POEMS syndrome. We conducted a retrospective analysis of 23 patients with confirmed POEMS syndrome. All of the patients received chest and abdominal CT scan and/or superficial ultrasound examinations. Four patients underwent PET/CT examinations, and 6 patients received lymph node biopsies. Enlarged lymph nodes (short diameter ≥ 1 cm) were found in 48% (11/23) of patients, but only 1 patie...
