“…In present study, the sensitivity of USG increased considerably owing to addition of multiple criteria and the fact that we used high-resolution USG and had a clinically suspected study population. Yahyazadeh and Mehraeen [26] , also reported both high sensitivity (91.7%) as well as high specificity (87.2%). Although, some workers like Stachs et al [21] , reported the sensitivity of conventional USG to be as high as 97.4% but reported the specificity to be too low (42.6%).…”

“…A slightly lower sensitivity and specificity of MRI (88% and 80%) has been reported by ElSaid et al [20] in their study. Among different studies reviewed by us, a few studies reported specificity of MRI to be less than 80% -reporting them to be 69.7%, 50% and 57.5% respectively [23][24][25][26][27][28] but both the studies found it to be highly sensitive with sensitivity of 92.5%, 100% and 98.2% respectively.…”

“…Although, some studies conducted among suspected women have reported this incidence to be less than 30%. (24)(25)(26)(27) As such the malignancy rate in different studies might vary substantially depending upon the inclusion criteria, strength of suspected clinical features, age and level of exposure to other risk factors.…”

Study aimed to evaluate and compare the performance of ultrasound, ultrasound elastography and magnetic resonance imaging in the diagnosis of breast cancer & its differentiation from benign lesions Material & Method: This cross-sectional observational study was conducted at department of Radiodiagnosis, Era's Lucknow Medical college. The study was conducted for 18 month from January 2019 to june 2020. Patients detected with breast lesions and willing to be part of study were included in the study. The patients with cystic nodules and non-consenting patients were excluded from the present study. All the patients were subjected to B-mode USG assessment followed with Real Time ultrasound Elastography and 0.5 Tesla MRI scan. Fine needle aspiration cytology (FNAC) or biopsy was performed and the specimen were evaluated cytologically/histopathologically to confirm the diagnosis Result: Histopathologically, 18 (36%) cases were diagnosed as malignant and remaining 32 (64%) were diagnosed as benign. Among 18 malignant cases, maximum (n=11) were intraductal carcinoma (NOS), followed by well-differentiated intraductal carcinoma (n=6) and invasive lobular carcinoma (n=1) respectively. Among 32 benign cases, maximum (n=20) were fibroadenoma, followed by breast abscess (n=3), galactocele, intraductal papilloma and simple cyst (n=2 each). There was 1 case each diagnosed as fibroadenolipoma, fibrocystic and phyllode respectively. Diagnostic efficacy of USG in terms of sensitivity, specificity, positive and negative predictive value was 77.8%, 87.5%, 77.8% and 87.5% respectively. The accuracy of USG diagnosis was 84%. Diagnostic efficacy of USG elastography in terms of sensitivity, specificity, positive and negative predictive value was 83.3%, 96.9%, 93.8% and 91.2% respectively. The accuracy of elastography diagnosis was 92%. Diagnostic efficacy of MRI in terms of sensitivity, specificity, positive and negative predictive value was 94.4%, 90.6%, 85.0% and 96.7% respectively. The accuracy of MRI diagnosis was 92%. Conclusion:In low-resource settings, USG elastography can emerge as a suitable alternative to MRI in diagnosis of malignant breast masses with highly appreciable positive and negative predictive values.

“…Magnetic resonance (MR) image reconstruction technology has been long-established in clinical medical detection with the rapid development of medical image processing technology. It has become an essential means of medical diagnosis [1][2][3]. In practical medical applications, the traditional approach is to sample data according to the Shannon-Nyquist sampling technique.…”

A Matching Pursuit Algorithm for Backtracking Regularization Based on Energy Sorting

2020

View full text Add to dashboard Cite

The signal reconstruction quality has become a critical factor in compressed sensing at present. This paper proposes a matching pursuit algorithm for backtracking regularization based on energy sorting. This algorithm uses energy sorting for secondary atom screening to delete individual wrong atoms through the regularized orthogonal matching pursuit (ROMP) algorithm backtracking. The support set is continuously updated and expanded during each iteration. While the signal energy distribution is not uniform, or the energy distribution is in an extreme state, the reconstructive performance of the ROMP algorithm becomes unstable if the maximum energy is still taken as the selection criterion. The proposed method for the regularized orthogonal matching pursuit algorithm can be adopted to improve those drawbacks in signal reconstruction due to its high reconstruction efficiency. The experimental results show that the algorithm has a proper reconstruction.

“…A pesar de los importantes avances tecnológicos y médicos, la prevalencia del cáncer entre la población se mantiente en niveles alarmantes (3) es en torno a qué métodos de detección son mejores y, sobre todo en Europa y América, demanda hacia los gobiernos por medidas que protejan la salud, en especial para mujeres (4) . Sustancialmente se solicita programas de salud pública que garanticen los medios para el diagnóstico temprano del cáncer, gratuitos y de calidad (5) .…”

Introducción: La prevalencia del cáncer es un problema que vas más allá de la preocupación médica, por cuanto involucra aspectos subjetivos y sociales en la vida de quienes lo padecen o están en riesgo. Por esto, es de gran importancia detectarlo tempranamente, especialmente entre mujeres debido a su exposición a los factores de riesgo de cáncer de mama y cérvix. Objetivo: Analizar la abstención femenina en Chile a la Mamografía y Papanicolaou. Materiales y métodos: Se realizó un análisis multivariado de regresión logística binomial, de los datos disponibles en el Módulo de Salud de la Encuesta de Caracterización Socioeconómica Nacional (CASEN) en su edición del año 2015. Resultados: Se expone una generalizada abstención a la acción preventiva entre mujeres, aun cuando la prevalencia de ambos tipos de cáncer es alta. Los motivos personales aparecen como los más comunes para omitir Mamografía y/o Papanicolaou, especialmente la subvaloración de su importancia. Los factores que aumentan la probabilidad de abstención son la baja escolaridad, la ausencia de afiliación médica y la presencia de pareja. Conclusiones: Se plantea la necesidad de aumentar igualmente la cobertura del servicio preventivo, focalizar los recursos hacia la población vulnerable y mejorar las estrategias de incentivo hacia estos exámenes.
