Cone Beam Computed Tomography Evaluation of Inverted Mesiodentes
CONCLUSION: The operating score reflects the course following functional endoscopic sinus surgery. Patients with more severe operative findings require longer post-operative treatment. PMID: 29665880 [PubMed - as supplied by publisher]
A 43-year-old female patient with migraines presented with right-sided headaches, jaw and ear pain, tongue and uvula deviation, right arm weakness, and dysphagia of solids and liquids resulting in a 7-pound weight loss. Neurologic examination included serologic and cerebrospinal fluid evaluation, which ruled out infectious, inflammatory, and paraneoplastic diseases. Magnetic resonance imaging of the brain and computed tomography angiography of the head and neck ruled out cerebrovascular accident and vasculitis.
Stenting at the flow-limiting segment can improve the ventilation-perfusion ratio in patients with central airway stenosis. However, there is no quantitative examination for assessing the perfusion status during interventional bronchoscopy. Intrabronchial capnography can estimate regional gas exchange by measuring carbon dioxide concentration. We herein report a case of bilateral bronchial stenosis where stenting was able to improve ventilation-perfusion ratio using intrabronchial capnography. A 44-year-old man was admitted to our institution with orthopnea. Chest computed tomography showed an extrinsic compression at the ...
CONCLUSION: A PETG 3D printed temporal bone models performed the best for realistic appearance and HF as compared with PLA, ABS, PC, and nylon. The PLA and ABS were reliable alternatives that also performed well with both measures. PMID: 29667491 [PubMed - in process]
CONCLUSION: Failure to recognize blunt trauma mechanism following firearm wounds increases the risk of missed injuries. Distant injuries should be suspected in all cases after blast wave and firearms exposure and a follow up should be done for many days to make sure such injuries are excluded. CT scan total body is recommended in all such cases. Key words: Blunt trauma, Distant Injuries, Firearm injuries, Pressure Waves. PMID: 29667607 [PubMed - in process]
Respiratory epithelial adenomatoid hamartoma is a relatively new diagnosis, only added to the World Health Organization classification of tumours in 2005. The lesion results from non-neoplastic overgrowth of glandular tissue in the nasal cavity and rarely in de sinus cavities and is often associated with nasal polyposis. The classical appearance of a bilateral mass in the olfactory cleft causing widening of the olfactory cleft allows the radiologist to suggest the diagnosis on computed tomography or magnetic resonance imaging.

Cardiac computed tomography angiography (CCTA) is a noninvasive imaging technique that has been rapidly adopted into clinical practice. Over the past decade, technological advances have improved CCTA accuracy, and there is an increasing amount of data supporting its prognostic value in the assessment of coronary artery disease. Recently, “appropriate use criteria” has been used as a tool to minimize inappropriate testing and reduce patient exposure to unnecessary risk and inconclusive studies. This review will summarize the appropriate uses of CCTA in patients before and after cardiac surgery. Although the most...
Conclusions: The prevalence as well as the rate of underreporting of incidental cardiac findings in non–ECG-gated chest CT of ICU patients is very high. The results of this study underscore the importance of dedicated training for assessment of cardiac structures and conditions, which may be detected on non–ECG-gated chest CT.
Conclusions: TETs with clearly invasive or metastatic features seen on CT are associated with having higher AJCC/UICC pathologic TNM stage, as expected. However, features of lobulated contour and heterogeneous internal density are also associated with higher stage disease. These findings need to be validated in an independent cohort.
Purpose: Dynamic computed tomography (CT) of the airways is increasingly used to evaluate patients with suspected expiratory central airway collapse, but current protocols are susceptible to inadequate exhalation caused by variable patient compliance with breathing instructions during the expiratory phase. We developed and tested a low-cost single-use expiratory airflow indicator device that was designed to improve study quality by providing a visual indicator to both patient and operator when adequate expiratory flow was attained. Materials and Methods: A total of 56 patients undergoing dynamic airway CT were evaluat...
