Non-Contact, Continuous Sampling of Porous Surfaces for the Detection of Particulate and Adsorbed Organic Contaminations by Low-Temperature Plasma Coupled to Ion Mobility Spectrometer.

Chemical analysis of hazardous surface contaminations, such as hazardous substances, explosives or illicit drugs, is an essential task in security, environmental and safety applications. This task is mostly based on the collection of particles with swabs, followed by thermal desorption into a vapor analyzer, usually a detector based on ion mobility spectrometry (IMS). While this methodology is well established for several civil applications, such as border control, it is still not efficient enough for various conditions, as in sampling rough and porous surfaces.

Male Breast Abscess Secondary to Actinomycosis: A Case Report.

Primary breast actinomycosis is a rare condition that has been previously reported in the female breast. Male breast infection is uncommon and most often associated with trauma to the skin or predisposing conditions like diabetes. We report the first case to our knowledge of primary breast actinomycosis in the male breast caused by Actinomycesneuii (A.

Mesenchymal breast lesions.

Mesenchymal breast lesions encompass a variety of breast diseases. Many of these lesions are rare with only a few case reports in the literature. This article reviews the imaging findings of selected mesenchymal breast lesions, their clinical presentations and method of diagnosis.

Granulomatous mastitis: changing clinical and imaging features with image-guided biopsy correlation.

Objectives: To review clinical presentation, revisit patient demographics and imaging findings in granulomatous mastitis and determine the optimal biopsy method for diagnosis.

Methods: A retrospective study was performed to review the clinical presentation, imaging findings and biopsy methods in patients with granulomatous mastitis. Twenty-seven patients with pathology-proven granulomatous mastitis were included.

Granular cell tumor in a male breast: mammographic, sonographic, and pathologic features.

Granular cell tumor (myoblastoma) is a rare soft tissue tumor that can present in the breast, producing mammographic and physical exam findings that may be indistinguishable from breast carcinoma. Multifocal lesions in male patients are very unusual. We present a case of a male patient with a granular cell tumor of the breast that was imaged on mammography and sonography.

Breast abscess after nipple piercing: sonographic findings with clinical correlation.

The purpose of this series was to review the spectrum of clinical and sonographic features associated with infection after nipple piercing. Between 2002 and 2010, 6 patients presented to our breast center with a breast abscess after nipple piercing. A retrospective analysis of the imaging findings was performed with clinical and pathologic correlation.

Breast problems presenting in the emergency room.

A variety of breast complaints may present in the emergency setting. Therefore, the radiologist in the emergency department must be familiar with the pathology encountered and the associated imaging findings. While mammography is the most commonly and frequently used modality for breast imaging, in the emergency setting, ultrasound may be more readily available and better tolerated by the patient.

Mucocelelike lesions of the breast: mammographic findings with pathologic correlation.

Objective: The purpose of this study was to review the imaging features of mucocelelike breast lesions, correlate the mammographic and pathologic findings, and determine recommendations for management.

Conclusion: Mucocelelike lesions are more common than previously reported and are likely to exhibit indeterminate calcifications on mammography. Diagnosis is most often made with Mammotome biopsy.

Experience with breast biopsies using the Advanced Breast Biopsy Instrumentation system.

Objective: A retrospective review of our experience with advanced breast biopsy instrumentation (ABBI) was undertaken to evaluate its efficacy for excisional breast biopsy of lesions detected on mammography. To our knowledge, experience with ABBI has not been previously reported in the radiology literature.

Materials And Methods: Biopsies using the ABBI system and an adapted dedicated table were performed in 53 patients who had 54 mammographically evident lesions.

Mammography of the postreconstruction breast.

Experience with mammographic examination of the reconstructed breast after mastectomy is limited. Typical mammographic changes associated with breast reconstruction are described. When these changes are identified on mammography, they can prevent patients from having unnecessary biopsies and can alleviate patient anxiety.

Mammographic and sonographic findings after silicone injection.

The illicit use of silicone injection for cosmetic augmentation was performed in the 1960s. However, this method of augmentation was subsequently abandoned. Recently, a resurgence of this practice has occurred.

Imaging of complications of augmentation mammaplasty.

The recent Food and Drug Administration hearings have brought new attention to breast implants and the importance of mammography in these patients to detect unsuspected breast pathology and complications of this surgical procedure. More patients are now being seen with implant failures in mammography departments. Very little attention has been paid to the mammographic findings and their significance until recently in the plastic surgery literature.

Tubular carcinoma of the breast: mammographic appearance.

Objective: Tubular carcinoma of the breast is an uncommon malignant growth that can have subtle mammographic findings. Tubular carcinoma is usually found incidentally during screening mammography. It can be differentiated from conventional breast cancers by its smallness and the lack of palpable findings on physical examination of the breast.

Imaging of breast cancer after augmentation mammoplasty.

Experience with mammography in patients with augmentation mammoplasty has been limited by the younger age of the patients and the bias of the physicians that mammography may be ineffective in imaging the breast with a prosthesis. With recent advances in imaging of the augmented breast and the increase in popularity of augmentation mammoplasty, more of these patients are undergoing mammography. We reviewed the mammograms and clinical history of 25 women with breast implants and breast cancer.

Mammography in women with axillary lymphadenopathy and normal breasts on physical examination: value in detecting occult breast carcinoma.

Objective: The purpose of this study was to determine the value of mammography in detecting occult carcinoma in patients with axillary adenopathy and normal breasts on physical examination.

Materials And Methods: We analyzed the results of mammography performed in 17 patients; all women had palpable axillary lymphadenopathy of unknown origin and all had normal breasts on physical examination.

Results: In 10 of the 17 patients, mammographic findings were abnormal.

Intraductal extension of silicone from a ruptured breast implant.

Silicone rupture is a known complication of closed capsulotomy. Imaging of silicone within breast tissue after rupture of an implant is not uncommon. Intraductal extension of silicone on mammography is a very rare finding.

Breast imaging and the augmented breast.

Women with augmented breast implants are presenting for mammograms in greater numbers over the past year due to recent publicity regarding the safety of silicone gel-filled implants. New issues are being raised in light of this recent increase, making it essential for patients and health care providers to understand the limitations of mammography and how to best minimize problems.

Breast cancer: mammographic and sonographic findings after augmentation mammoplasty.

The authors retrospectively reviewed 11 cases of breast cancer in patients who had undergone augmentation mammoplasty. The mammogram or sonogram was abnormal in 10 patients, including six with an abnormal mammographic density or ultrasound study and four with calcifications. One patient had dense breasts and no suspicious findings at mammography.

Transvaginal sonography: comparison with transabdominal sonography in the diagnosis of pelvic masses.

In a retrospective study, we compared transvaginal sonograms with transabdominal sonograms in 67 women referred for evaluation of palpable pelvic masses. The diagnoses included ovarian cyst (27), endometrioma (12), complex cyst (four), dermoid (three), infection (three), ovarian malignancy (two), and uterine fibroid (three). The final diagnosis was made surgically in 41 patients (61%) and by a combination of sonographic and clinical correlation in the remaining patients.
