Detection of coronary artery calcification with nontriggered computed tomography of the chest

<div><p>Abstract Objective: To evaluate the accuracy of visual analysis and of the coronary artery calcium (CAC) score in nontriggered computed tomography (CT), in comparison with that of the CAC score in electrocardiogram-triggered CT, in identifying coronary calcification. Materials and Methods: A total of 174 patients for whom CT was indicated for CAC scoring underwent nontriggered and triggered CT in a 64-channel multislice scanner, in a single session without a change in position. The images were interpreted by a radiologist with seven years of experience in thoracic and cardiovascular radiology. The measurement of coronary calcium was carried out by three methods: CAC score with dedicated software in nontriggered CT, CAC score with dedicated software in triggered CT, and visual analysis without dedicated software in nontriggered CT. Results: In nontriggered CT, the CAC score presented an accuracy of 95.98% (95% CI: 91.93-98.04). The visual analysis showed an accuracy of 97.13% (95% CI: 93.45-98.77). Conclusion: Nontriggered CT showed excellent accuracy in the identification and exclusion of coronary calcification, either the CAC score was determined with dedicated software or through visual analysis.</p></div

TOMOGRAPHIC FINDINGS OF GASTRIC GASTROINTESTINAL STROMAL TUMOR AND CORRELATION WITH THE MITOTIC INDEX

ContextGastrointestinal stromal tumors are uncommon abdominal neoplasms and can affect any portion of the gastrointestinal tract.ObjectivesDescribe the tomographic findings of the gastrointestinal stromal tumor of gastric origin, correlating it with the mitotic index.MethodsTwenty-one patients were selected within the period of January 2000 and 2008, with histopathological and immunohistochemical diagnosis of gastric gastrointestinal stromal tumors, who presented computed tomography done before the treatment. The tomographic variables analyzed were lesion topography, dimensions, contours, morphology, pattern and intensity enhancement through venous contrast, growth pattern, invasion of adjacent organs, presence of ulceration, fistula, calcifications, infiltration of mesenteric fat, lymphadenopathy and metastasis. The mitotic index was determined through optic microscopy, counting the number of mitosis figures in 50 high power fields.ResultsThe tumors were located in the body (66.7%) or gastric fundus (33.3%), with dimensions varying between 4.2 and 21.2 cm (average of 10.5 cm). The growth was predominantly extraluminal (47.6%) or intra/extra luminal (28.6%). The enhancement by venous contrast was heterogeneous in 66.7%. The statistical analysis showed that irregular morphology (P = 0.027) and infiltration of mesenteric fat (P = 0.012) presented correlation with the high mitotic index.ConclusionsIn the present study, most part of the tumors were located in the gastric body, with average size of 10.5 cm, presenting central hypo dense area, heterogeneous enhancement through contrast and predominantly extra luminal growth. Irregular morphology and infiltration of mesenteric fat present statistical correlation with high mitotic level

Aspectos tomográficos do tumor estromal gastrintestinal de origem gástrica: estudo de 14 casos Tomographic findings of gastric gastrointestinal stromal tumor: a 14-case study

OBJETIVO: Descrever os achados tomográficos do tumor estromal gastrintestinal de origem gástrica. MATERIAIS E MÉTODOS: No período de janeiro de 1999 a dezembro de 2006, foram selecionados 14 pacientes com diagnóstico histopatológico e imuno-histoquímico de tumor estromal gastrintestinal gástrico que apresentavam tomografia computadorizada realizada anteriormente ao tratamento. As variáveis tomográficas analisadas foram: topografia da lesão, dimensões, homogeneidade, contornos, limites, morfologia, padrão e intensidade do realce pelo meio de contraste venoso, padrão de crescimento, invasão de órgãos adjacentes, presença de ulceração, fístula, calcificações, infiltração da gordura mesentérica, linfonodomegalias e metástases a distância. RESULTADOS: Os tumores foram localizados no corpo (57,1%) ou fundo gástrico (42,9%), com dimensões variando entre 6,0 e 23,0 cm (média de 11,5 cm). O crescimento foi predominantemente extraluminal (57,1%) ou intra/extraluminal (35,7%). O realce pelo contraste venoso foi discreto em 50% dos casos, moderado em 50% e heterogêneo em 64,3%. Foram ainda observadas hipodensidade central em 64,3% dos casos, invasão de órgãos adjacentes em 42,9% e metástases hepáticas em 7,2%. CONCLUSÃO: No presente estudo, a maioria dos tumores localizava-se no corpo gástrico, com tamanho médio de 11,5 cm, apresentando área hipodensa central, realce heterogêneo pelo meio de contraste e crescimento predominantemente extraluminal.<br>OBJECTIVE: The purpose of this study was to describe the tomographic findings of gastric gastrointestinal stromal tumor. MATERIALS AND METHODS: Fourteen patients with histopathologically and immunohistochemically confirmed gastric gastrointestinal stromal tumors, who had already been submitted to computed tomography scans before the treatment, were evaluated in the period between January 1999 and December 2006. The following tomographic variables were analyzed: lesion topography, size/dimensions, homogeneity, contour, margins, morphology, pattern and intravenous contrast-enhancement intensity, growth pattern, invasion of adjacent organs, presence of ulceration, fistula, calcifications, mesenteric fat infiltration, lymphadenomegaly and presence of distant metastasis. RESULTS: Tumors were found in the body (57.1%) or in the gastric fundus (42.9%), with sizes ranging between 6.0 cm and 23.0 cm (mean, 11.5 cm). Predominantly extraluminal growth was observed in 57.1% of cases and intra/extraluminal in 35.7%. Subtle contrast-enhancement was observed in 50%, moderate in 50%, and heterogeneous in 64.3% of cases. Additionally, central hypodensity was observed in 64.3%, invasion of adjacent organs in 42.9%, and hepatic metastasis in 7.2% of cases. CONCLUSION: In the present study, the majority of tumors were found in the gastric body, with an average size of 11.5 cm, presenting with central hypodensity, heterogeneous contrast-enhancement and predominantly extraluminal growth
