AbstractSevere pelvic fractures often prove difficult for surgeons as they require patient-specific surgical treatment plans and customized equipment. Developing virtual patient-specific 3D pelvis models would ease the surgical planning process and enable development of custom fixation plates. This paper aims to examine pelvic symmetry to conclude whether the contralateral side may be used as a reference model for the fractured side of the pelvis. Fourteen subjects with intact pelvises were involved in this study. CT scans of the pelvises were converted to 3D models and the right sides of the pelvises were reflected and al...

ConclusionComputed tomography examinations are a more reliable method for differential diagnosis of thyroid nodules than ultrasound examinations followed by fine needle aspiration biopsy.Level of EvidenceIII.ResumoIntroduçãoA ultrassonografia é um método rápido para determinar de qual nódulo deve-se coletar uma amostra para biópsia por aspiração com agulha fina. Por outro lado, o exame de tomografia computadorizada não é restringido pela atenuação do eco e distingue entre nódulos benignos e malignos.ObjetivoComparar exames tom...

This article describes an approach to analyzing the distribution of intravenous contrast on chest computed tomography and illustrates the various pathologies and pitfalls that may be encountered by the imager, especially in the hospitalized patient. Understanding normal and abnormal distribution of intravenous contrast can be used as a clue to detect alterations in physiology and flow. PMID: 31731905 [PubMed - in process]

Abstract Abdominal pain is a common cause for emergency department visits in the United States, and biliary tract disease is the fifth most common cause of hospital admission. Common causes of acute hepatobiliary include gallstones and its associated complications and multiple other hepatobiliary etiologies, including infectious, inflammatory, vascular, and neoplastic causes. Postoperative complications of the biliary tract can result in an acute abdomen. Imaging of the hepatobiliary tree is integral in the diagnostic evaluation of acute hepatobiliary dysfunction, and imaging of the biliary tree requires a multimo...

Abstract Neuroimaging is an invaluable diagnostic tool for sorting through the vast array of etiologies that underlie altered mental status (AMS). Head computed tomography (CT) without contrast is the primary modality for evaluation of AMS and should be complemented by MR imaging in cases of negative CT but high clinical concern. Studies to maximize brain imaging efficiency and improve the yield of positive scans through the utilization of clinical and laboratory pre-scan diagnostics are ongoing. However, imaging remains the gold standard due to its rapidity with which certain diagnoses can be made or excluded. ...

Abstract There is a wide variety of causes of diffuse lung disease in the intensive care unit patient, of which adult respiratory distress syndrome is the commonest clinical consideration. Plain radiography, computed tomography, and ultrasound can be used synergistically to evaluate patients with diffuse lung disease and respiratory impairment. Imaging is not limited to characterization of the cause of diffuse lung disease but also aids in monitoring its evolution and in ventilator setting management. PMID: 31731896 [PubMed - in process]

ConclusionsWe have developed a HYNIC-modified Tz derivative, and the HYNIC-PEG11-Tz was labeled with Tc-99m with a high specific activity and radiochemical purity. [99mTc]HYNIC-PEG11-Tz reacted rapidly and almost completely towards atezolizumab-TCOin vitro with the 1:1 Tz-to-mAb reaction. SPECT imaging using the pretargeted strategy (atezolizumab-TCO/[99mTc]HYNIC-PEG11-Tz) demonstrated high-contrast images for high PD-L1 expression H1975 tumor and a low background accumulation of the probe. The pretargeted imaging strategy is a powerful tool for evaluating PD-L1 expression in xenograft mice tumor models and a potential can...

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.
