Objective(s): Controversy exists about the localization of non-palpable breast lesions. In many countries, the gold standard for the diagnosis of these lesions is needle localization due to its accuracy. This study sought to compare the ultrasoundand radio-guided occult lesion localization (ROLL) as a simple method with the conventional procedures in terms of their diagnostic power. Methods: Th...
The breast cancer is common in females.Early detection with safe , convenient , noninvasive and accessible diagnostic tools are important. X- ray mammography is still the first choice imaging for breast cancer, but has low specificity and limited value in dense breast and surgically scarred breasts. In recent years , MIBI scintimammography has been used for this purpose. The...
Dermatomyositis (DM) is a rare idiopathic inflammatory myopathy with characteristic skin lesions. Case series have shown an association between dermatomyositis and malignancy. Malignancy has been found in 15-25% of the adult patients with dermatomyositis. A 50-year-old new case of breast cancer, was admitted with muscle weakness and inability to walk. Physical examination revealed fever, perior...
Accurate segmentation plays a vital role in automated analysis of ultrasonic images. A new method based on adaptive anisotropic diffusion is introduced here for lesion detection in ultrasonic images of the breast. In this method, a hypothesis testing framework is defined first to separate lesions from healthy breast tissue. Then the boundary of lesion is estimated by adaptive anisotropic diffus...
Background: Breast cancer is one of the most common cancers worldwide in females and an important cause mortality morbidity. FNAC a safe, reliable, sensitive, specific, time saving cost effective procedure useful diagnosis carcinoma breast. It helps surgeon planning treatment, thereby reducing delay treatment. The primary aim this study to find out spectrum breast lesions on fine needle aspirat...
conclusions although in our study washout pattern was the most powerful indicator for malignant pathology in non mass like enhancing lesions, more studies with larger sample size needs in this regard. background several studies on the diagnostic efficacy of mri has not real consensus for the accuracy of mri characteristics in non mass like breast lesions, and the number of malignant lesions in ...
Purpose: Dynamic contrast-enhanced (DCE)-MRI has a promising role in breast cancer detection and lesion characterisation. Diffusion-weighted imaging (DWI) acts as an adjunct the differentiation between benign malignant lesions. The purpose of study was to evaluate efficacy DCE-MRI DWI differentiating Methods: In prospective conducted March 2019 February 2020, 60 patients with lesions underwent ...
As breast magnetic resonance imaging (MRI) is being used more frequently to screening and diagnosis of breast malignancies, we often encounter various breast skin lesions appearing as skin thickening or enhancement. Although numerous studies have reported about the breast parenchymal lesions, the dermal lesions of the breast have largely been overlooked. The breast skin lesions may be incidenta...
In this paper, we evaluate the radiological features of pregnancy-associated breast lesions and discuss the difficulties in diagnosis by imaging. We selected patients who were diagnosed with pregnancy-associated breast lesions during the previous 5 years. All patients complained of palpable lesions in the breast and underwent ultrasonographic (US) examination, the first choice for examination o...
in this paper the breast lesions, more particularly the carcinomas. have been studied in the taj pahlavi cancer institute, teheran , iran, from 1956 through 1971. in this period of 15 years the number of breast lesions observed have been 2107 cases of which 1023 cases or 48.5 %have had reference to carcinomas especially among women, the ratio of females to males suffering from this type oflesio...
