Resumen

Objective: This pilot study was undertaken to compare radiation dose, relative visibility/conspicuity of biopsy-proven lesions, and relative patient comfort in diagnostic mammography and dedicated cone-beam breast computed tomography (CBBCT) in Breast Imaging-Reporting and Data System (BI-RADS)® 4 or 5 lesions. Materials and Methods: Thirty-six consecutive patients (37 breasts) with abnormal mammographic and/or ultrasound categorized as BI-RADS® 4 or 5 lesions were evaluated with CBBCT prior to biopsy. Administered radiation dose was calculated for each modality. Mammograms and CBBCT images we

Resumen

Purpose: To evaluate the contribution of guided fine-needle aspiration cytology in reducing unnecessary biopsies of benign solid nonpalpable breast lesions with low suspicion of malignancy at mammography. Material and Methods: An evaluation was made of a consecutive series of 2444 solid nonpalpable breast lesions detected by mammography and undergoing guided (sonography or stereotaxy) fine-needle aspiration cytology. Surgical biopsy was made in the presence of strong suspicion of malignancy at mammography and/or of abnormal cytology. Results: The sensitivity was 96.7% and the specificity 77.7%

Resumen

Introduction: Mammography is a simple and effective tool in early detection of breast lesions. However its sensitivity is less in dense breast. The aim of the study is to see whether addition of ultrasonography adds on to the diagnostic value by finding more breast lesions in evaluation of mammographic dense breasts or not.  Methods: The hospital data of all the patients who underwent mammography in the Department of Radiology of Shree Birendra Hospital, Kathmandu over a period of two and a half years from November 2017 to April 2020 were retrieved and retrospectively analyzed.

Background/Aim. Posterior breast cancers are located in the prepectoral region of the breast. Owing to this distinctive anatomical localization, physical examination and mammographic or ultrasonographic evaluation can be difficult.

Resumen

Background The limited sensitivity of mammography in case of a high breast density often produces unclear or false-positive findings, so-called BI-RADS 3 lesions, which have to be followed up to prove benignity. Digital breast tomosynthesis (DBT) was developed to reduce such summation effects. Purpose To evaluate the influence of an additional DBT on the management of mammographic BI-RADS 3 findings and whether DBT can decrease the time to definitive diagnosis or not. Material and Methods We analyzed 87 patients with a mammographic non-calcified BI-RADS 3 lesion who underwent an additional DBT

This retrospective study was designed to determine the effect of this conversion on positive predictive values (PPV) for cancerous and precancerous breast lesions. Methods: In the Calgary region, biopsies for mammographic calcifications are only done at Foothills Medical Centre (FMC) by a small group of mammographers employing homogeneous techniques.

Hemangiomas are vascular lesions, which are only rarely located in the breast. Larger breast hemangiomas may be detected by clinical examination, mammography, and breast ultrasound, whereas smaller lesions are usually incidental findings. We present a rare case of a 43-year-old woman with a cavernous hemangioma of the breast, presenting only on MRI and evading mammographic and ultrasonographic imaging. On breast MRI, a small lesion with irregular margins was detected in the right breast, and following gadolinium contrast medium administration, a type 3 curve, with rapid initial rise, followed

Abstract Background Radiology reports are usually narrative, unstructured text, a format which hinders the ability to input report contents into decision support systems. In addition, reports often describe multiple lesions, and it is challenging to automatically extract information on each lesion and its relationships to characteristics, anatomic locations, and other information that describes it. The goal of our work is to develop natural language processing (NLP) methods to recognize each lesion in free-text mammography reports and to extract its corresponding relationships, producing a com

Resumen

Purpose: The aim of our prospective study was to determine the diagnostic accuracy of MR mammography (MRM) in detecting malignant disease. Material and Methods: In 231 consecutive patients scheduled for surgery because of mammographic or palpable lesions suspected of malignancy, the breasts were examined with T1-weighted transversal images using a 3-D fast low angle shot (FLASH) sequence. One pre- and 2 post-contrast images were obtained. Histological examination of the surgical specimens showed carcinoma in 155 breasts, of which 138 were invasive and 17 in situ. Results: MRM detected 144 of t

Objective To compare the capacity of mammography, sonoelastography, B-mode ultrasonography and histological analysis to differentiate benign from malignant breast lesions. Materials and Methods A total of 12 histopathologically confirmed breast lesions were documented. The lesions were assessed by means of mammography, B-mode ultrasonography and sonoelastography, and histopathological analysis was utilized as a gold standard. Sensitivity and specificity were calculated. A receiver operating characteristic (ROC) curve was constructed to evaluate the diagnostic performance of the mentioned techn

Results: 1361 women had aspiration cytology performed from a total of 47,718 mammography non-negative lesions. 105 (7.8%) were diagnosed as C3, whereas 78 (5.7) as C4.

Resumen

SummaryDespite low specificity routine mammography is the method of choice to screen women for breast cancer. In addition high frequency ultrasonography (US) or magnetic resonance imaging (MRI) can improve breast cancer diagnosis. However there is a lack of conventional imaging to improve the high rate of false positive results that make biopsy or surgery necessary. Aim: The purpose of our study was to evaluate prospectively the sensitivity, specificity, PPV and NPV of scintimammography with a new cationic complex Tc-99m-tetrofosmin.

Resumen

Background: Detection of malignant lesion leads to early initiation of definitive treatment or its exclusion saves the patient from unnecessary medication and psychological trauma. It is difficult to establish the nature of the lesion merely on the clinical examination. So “triple” test is suggested, which is a mixture of clinical examination, mammography and FNAC.Methods: The results of clinical examination, mammography and FNAC were compared with those of histopathological examination. The concordant results of the “triple test” were compared with those of the histopathological examination.

Background: Great importance in detecting in situ cancer is in the fact that epithelial layer is deprived of the blood and lymph vessels, so metastases can develop only when basal membrane has been broken. Methods: The paper included 40 operated women in whom preoperatively suspect non-palpable lesion had been verified. Preoperative diagnostics included use of high-resolution mammography, aimed mammography, palpatory examination of surgeon-oncologist, as well as fine-needle aspiration (FNA) biopsy and cytology analysis of the sample.

Background: Mammography can identify calcifications up to 50–100 μm in size as a surrogate parameter for breast cancer or ductal carcinoma in situ (DCIS). Microcalcifications measuring <50 µm are also associated with breast cancer or DCIS and are frequently not detected on mammography, although they can be detected with dark-field imaging. This study examined whether additional breast examination using X-ray dark-field imaging can increase the detection rate of calcifications.

Resumen

Marking of non-palpable breast lesions for biopsy has become a routine procedure in patients in whom mammography has suggested malignancy. Between October 1981 and December 1985 a localization method was used in 123 patients. In 35 per cent of the biopsies a malignant lesion was disclosed. In patients with a mass only, malignancy was found in 37 per cent of the biopsies. If microcalcifications alone were the main reason for the biopsy, malignancy was disclosed in 25 per cent. If both a mass and microcalcifications were present, 52 per cent of the biopsies disclosed a malignant lesion.

Resumen

Abstract The early detection of carcinoma is the highlight of mammography. We present two patients with pathological diagnosis of DCIS with unusual mammographic findings for which one needs to have a higher index of suspicion. The first patient presented with multifocal disease requiring biopsy of all visible lesions and the second patient (twenty four years old) presented with segmental distribution of calcifications, which may have been missed had a single-view baseline mammogram not been done.
