“…Although it has been reported that panoramic radiography has low sensitivity in detecting calcified carotid atheroma [20][21][22], no study has systematically investigated its reliability in the detection of carotid atheromas in MetS. Therefore, the aim of this study was to determine the sensitivity and specificity of panoramic radiography in detecting carotid atheromas in patients with MetS by comparing with ultrasonographic findings.…”

Objective To determine the sensitivity and specificity of panoramic radiography in detecting carotid atheromas in patients with metabolic syndrome (MetS) by comparing ultrasonographic findings. Methods Panoramic radiography and ultrasonography were performed in 85 MetS patients to determine the presence of carotid atheroma. The panoramic radiographic findings were classified into calcified plaque and no calcified plaque. The ultrasonic findings were divided into four groups: calcified plaque, calcified and soft (mixed) plaque, soft plaque, and no plaque. Results In identifying calcified carotid plaques, panoramic radiography had a sensitivity of 42.19%, a specificity of 97.17%, a positive predictive value of 90.00%, and a negative predictive value of 73.57%. Of 170 carotid sites, ultrasonography identified 37 calcified plaques and 9 soft plaques that were not detected by panoramic radiography.Conclusions Panoramic radiography has moderate sensitivity and high specificity in detecting calcified carotid plaques and is limited in the detection of soft carotid plaques.

“…The main radiopacities which may be confused with CACs during image observation correspond to calcified lymph nodes, sialoliths, phleboliths, hyoid bone, calcification of the styloid and stylomandibular ligaments, as well as those of the triticeal, cricoid and thyroid cartilages (11,25,26) . The clinical importance of such a radiographic finding is so high that the dental literature recommends that patients whose images suggest the presence of CACs be referred for cardiovascular evaluation (13,27,28) .…”

Reliability of digital panoramic radiography in the diagnosis of carotid artery calcifications * Confiabilidade da radiografia panorâmica digital no diagnóstico de calcificações na artéria carótida Brasileiro Junior VL, Luna AHB, Sales MAO, Rodrigues TLC, Sarmento PLFA, Mello Junior CF. Reliability of digital panoramic radiography in the diagnosis of carotid artery calcifications. Radiol Bras. 2014 Jan/Fev;47(1):28-32. Abstract ResumoObjective: The present study evaluated the reliability of digital panoramic radiography in the diagnosis of carotid artery calcifications. Materials and Methods: Thirty-five patients under high-risk for development of carotid artery calcifications who had digital panoramic radiography were referred to undergo ultrasonography. Thus, 70 arteries were assessed by both methods. The main parameters utilized to evaluate the panoramic radiography reliability in the diagnosis of carotid artery calcifications were accuracy, sensitivity, specificity and positive predictive value of this method as compared with ultrasonography. Additionally, the McNemar's test was utilized to verify whether there was a statistically significant difference between digital panoramic radiography and ultrasonography. Results: Ultrasonography demonstrated carotid artery calcifications in 17 (48.57%) patients. Such individuals presented with a total of 29 (41.43%) carotid arteries affected by calcification. Radiography was accurate in 71.43% (n = 50) of cases evaluated. The degree of sensitivity of this method was 37.93%, specificity of 95.12% and positive predictive value of 84.61%. A statistically significant difference (p < 0.001) was observed between the methods evaluated in their capacity to diagnose carotid artery calcifications. Conclusion: Digital panoramic radiography should not be indicated as a method of choice in the investigation of carotid artery calcifications.Keywords: Carotid artery calcification; End-stage renal disease; Panoramic radiography; Ultrasonography.Objetivo: O presente estudo avaliou a confiabilidade da radiografia panorâmica digital no diagnóstico de calcificações na artéria carótida. Materiais e Métodos: Trinta e cinco pacientes de alto risco para o desenvolvimento de calcificações na artéria carótida que tinham a radiografia panorâmica digital foram encaminhados para realização do exame de ultrassonografia. Assim, 70 artérias foram avaliadas pelos dois exames. Os principais parâmetros utilizados para avaliar a confiabilidade da radiografia panorâmica no diagnóstico de calcificações na artéria carótida foram a precisão, a sensibilidade, a especificidade e o valor preditivo positivo desse método quando comparado à ultrassonografia. Além disso, o teste de McNemar foi utilizado para verificar se existia diferença estatisticamente significante entre a radiografia panorâmica digital e ultrassonografia. Resultados: De acordo com a ultrassonografia, 17 (48,57%) pacientes apresentavam calcificações na artéria carótida. Esses indiví-duos apresentavam um total de 29 (41,43%) artérias carótidas a...

“…For a number of years, panoramic radiographs have been suggested as a tool for detecting carotid artery calcificationsbecause these anatomic structures are potentially within the visual field of these radiographs [1][2][3][4][5][6][7][8][9][10][11]. However, data suggest panoramic radiographs have low sensitivity and positive predictive value and are considered unreliable for detecting carotid artery calcification [12][13][14][15]. In the beginning of the 1980s, ultrasound measurement of carotid arteries was introduced and this assessment is currently available in clinical practice [16].…”

It has been suggested that atherosclerotic plaques can be visualized in a panoramic radiograph but this tool is not reliable for systematic screening of patients due to its low sensitivity. This study investigated the potential role for dental practitioners in using an ultrasound machine to detect carotid artery plaques. 100 subjects completed a survey concerning theiratherosclerosis risk factors. Bilateral images and digital video clips of the carotid arteries of each person were obtained with a portable high-resolution ultrasound device equipped with an L38/10-5 MHz linear-array transducer. Images were subsequently interpreted. We found images suggestive of atherosclerotic plaque build-up in two Caucasian females: one 59 year-old with risk factors including: past smoker, high cholesterol, and family history of atherosclerosis and one 54 year-old with risk factors including: past smoker, overweight, and reported no physical activity. Both individuals were referred to their primary care providers for further assessments. 2% of the patient adult population may have carotid blockages detectable by ultrasound. The frequency can be as high as 5.5% in individuals older than 50. In the dental setting, ultrasound imaging can be used to capture bilateral pictures of the carotid arteries. With these images, at-risk patients may be screened for atherosclerotic plaques that could ultimately form a strokecausing embolus. The dentist is particularly well suited for this role because he/she sees patients every six months while a physician can go years without seeing his/her patients.
