Referral pattern to a university-based oral and maxillofacial cone beam CT service

Conclusions: All dental specialties refer patients for CBCT examinations but at different frequencies and for various reasons that pertain to their respective disciplines. Clinical significance: These findings should be the basis for customizing the availability and scope of imaging services and in developing and modifying educational programmes for dentists and dental specialists.

We report a case of a diagnostic dilemma in a patient with pulmonary melioidosis which radiologically mirrored a bronchogenic carcinoma with mediastinal lymphadenopathy. Such findings were observed in a Computed Tomography (CT) scan (Thorax) and Positron Emission Tomography (PET) scan (Body) in a previously healthy 57-year-old man with no significant medical risk factors for melioidosis other than his previous exposures to soil during outfield military training in Thailand, 37 and 28 years ago. He presented with acute symptoms of dry cough, pleuritic pain and fever. A CT Scan thorax revealed a left lower lobe mass with lef...

ConclusionsThe XP-endo Finisher instrument promoted better distribution of irrigant throughout the root canal system, especially in the apical canal segment, when compared to PUI. However, the tested approaches did not differ as to the ability to drive irrigants into the isthmus area.Clinical relevanceThis study highlighted that the XP-endo Finisher instrument presented a better performance to distribute irrigant throughout the root canal system, especially in the apical canal segment compared to positive pressure irrigation and PUI.

The vertical intensity distribution of synchrotron-based X-ray beams usually has a Gaussian profile encompassing large intensity variations. For biomedical imaging applications this may entail sub-optimal dose distributions and large fluctuations in terms of image noise. Commonly, planar metallic filters coupled with absorbing slits systems are applied to adjust the delivered flux and to limit intensity variations, respectively. The latter results in a reduction of the effective beam size. A flattening filter that counterbalances the transverse inhomogeneity, while retaining a sufficient flux, has been developed in the con...

AbstractBackgroundThe purpose of this study is to investigate the performance of dual-layer detector spectral CT for iron deposition compared to magnetic resonance imaging (MRI) T2* imaging.MethodsThirty-one patients with a clinical history of myelodysplastic syndromes and aplastic anemia underwent liver and cardiac T2*-weighted unenhanced MRI on a three-tesla MRI scanner, and underwent unenhanced CT scan laterally on a 128-row spectral detector CT. R2* values of the liver, septal muscle, and paraspinal muscle were calculated. Attenuation differences ( ΔH) in the liver and myocardium were calculated between the lower...

Conclusion: It may be employed either alone or in combination with cryotherapy, existing chemotherapy, bypass surgery or radiations to achieve the optimal results in these patients. Nevertheless, there is a need to formulate a uniform dose and procedure to achieve homogeneity and develop references for clinical practices. PMID: 31977258 [PubMed - as supplied by publisher]

Authors: Sun Z Abstract Three-dimensional (3D) is increasingly used in medical applications with most of the studies focusing on its applications in medical education and training, pre-surgical planning and simulation, and doctor-patient communication. An emerging area of utilising 3D printed models lies in the development of cardiac computed tomography (CT) protocols for visualisation and detection of cardiovascular disease. Specifically, 3D printed heart and cardiovascular models have been shown potential value in the evaluation of coronary plaques and coronary stents, aortic diseases and detection of pulmonary e...
