“…69 Future directions Advances in MDCT hardware (wide detector panel, gantry rotation speed reduction and new detector composition and structure) and software post-processing evolution (automatic CAD of vessel stenosis, three-dimensional modelling, calcification subtraction and enhancing) are opening a new era, which will improve patient safety (reduction of dose and CM), reduce cost and improve patient care in this group of patients. [74][75][76][77][78][79][80][81] With better understanding of predisposition and genetic risk, acute AD might soon become predictable and, to some degree, preventable by new biomarkers. The description of any given dissection will be individualized by addressing specific features rather than using simple classification systems of the past.…”

Non-traumatic acute thoracic aortic syndromes (AAS) describe a spectrum of life-threatening aortic pathologies with significant implications on diagnosis, therapy and management. There is a common pathway for the various manifestations of AAS that eventually leads to a breakdown of the aortic intima and media. Improvements in biology and health policy and diffusion of technology into the community resulted in an associated decrease in mortality and morbidity related to aortic therapeutic interventions. Hybrid procedures, branched and fenestrated endografts, and percutaneous aortic valves have emerged as potent and viable alternatives to traditional surgeries. In this context, current state-of-the art multidetector CT (MDCT) is actually the gold standard in the emergency setting because of its intrinsic diagnostic value. Management of acute aortic disease has changed with the increasing realization that endovascular therapies may offer distinct advantages in these situations. This article provides a summary of AAS, focusing especially on the MDCT technique, typical and atypical findings and common pitfalls of AAS, as well as recent concepts regarding the subtypes of AAS, consisting of aortic dissection, intramural haematoma, penetrating atherosclerotic ulcer and unstable aortic aneurysm or contained aortic rupture. MDCT findings will be related to pathophysiology, timing and management options to achieve a definite and timely diagnostic and therapeutic definition. In the present article, we review the aetiology, pathophysiology, clinical presentation, outcomes and therapeutic approaches to acute aortic syndromes.

“…Based on the ability of DECT to reduce hardening artifacts by monochromatic imaging, the new generation of 16-cm-wide detector Revolution CT incorporates MMAR technique into the volume reconstruction algorithm [26]. In this technique, different substances are separated in the image reconstruction, aiming to reduce or even eliminate hardening artifacts and improve the image quality.…”

Background: This study aimed to explore the performance of Revolution CT virtual monoenergetic images (VMI) combined with the multi-material artifact reduction (MMAR) technique in reducing metal artifacts in oral and maxillofacial imaging. Results: There were significant differences in image quality scores between VMI + MMAR images and VMI+MARS (multiple artifact reduction system) images at each monochromatic energy level (p = 0.000). Compared with the MARS technology, the MMAR technology further reduced metal artifacts and improved the image quality. At VMI 90 keV and VMI 110 keV , the SD, CNR, and AI in the Revolution CT group were significantly lower than in the Discovery CT, but no significant differences in these parameters were found between two groups at VMI 50 keV , VMI 70 keV , and VMI 130 keV (p > 0.05). The attenuation was comparable between two groups at any energy level (p > 0.05). Conclusions:Compared with the MARS reconstruction technique of Discovery CT, the MMAR technique of Revolution CT is better to reduce the artifacts of dental implants in oral and maxillofacial imaging, which improves the image quality and the diagnostic value of surrounding soft tissues.Compared to the 64-slice Discovery CT VMI + MARS technique for image reconstruction, 256-slice Revolution CT VMI + MMAR technique for image reconstruction is better to reduce metal artifacts and background SD. The combined use of VMI 110 keV + MMAR technique is helpful for the observation and evaluation of small structures around the metal implants. The combined use of VMI 110 keV + MMAR technique also provides a better diagnostic tool in clinical practice.

“…Do ponto de vista técnico, a TC sofreu várias melhorias ao longo dos anos, como aumentar o número de detectores, tempo para cortar a imagem, reduzir artefatos e resolução de imagens ampliadas, fornecendo informações mais úteis para o diagnóstico com reduzida exposição a radiação. Os rápidos avanços nessa tecnologia levaram a estudos clínicos de diagnóstico e prognóstico em larga escala em várias populações de pacientes (CHAIKRIANGKRAI, 2014).…”
