The addition of SWE to B-mode US improved diagnostic performance with increased specificity for screening US-detected breast masses. BI-RADS category 4a masses detected at US screening that showed a dark blue color or a maximum elasticity value of 30 kPa or less on SWE images can be safely followed up instead of performing biopsy.

Ultrasound (US) elastography is a valuable imaging technique for tissue characterization. Two main types of elastography, strain and shear-wave, are commonly used to image breast tissue. The use of elastography is expected to increase, particularly with the increased use of US for breast screening. Recently, the US elastographic features of breast masses have been incorporated into the 2nd edition of the Breast Imaging Reporting and Data System (BI-RADS) US lexicon as associated findings.

본 연구는 조력기술 수행, 회기관리 및 힘든 상담상황에 대처하는 상담자들의 지각된 능력을 측정하기 위해 외국에서 개발된 상담자 활동 자기효능감 척도를 타당화하려는 목적으로 진행되었다. 이를 위해 서울, 경기 지역에 있는 대학상담실, 청소년 상담센터, 개인 상담소에서 전문상담자로 활동하고 있거나 수련중인 118명(여자 106명, 남자 12명)의 상담자들을 대상으로 상담자 활동 자기효능감 척도를 실시하고 신뢰도 및 타당도를 확인하였다. 우선, 탐색적 요인분석을 실시한 결과 5개의 하위요인이 적절한 것으로 드러났고(조력기술 3요인, 회기관리 1요인, 상담난제 1요인), 각각의 하위요인이 적절한 신뢰도를 지닌 것으로 나타났다. 또한, 상담자 활동 자기효능감 척도는 상담자 발달수준 척도와 높은 상관을, 사회적 정향성 척도와는 낮은 상관을, 상태불안 척도와 중간 이상의 부적 상관을 갖는 것으로 드러나 적절한 타당도를 지니고 있음이 확인되었다. 그리고 상담자 활동 자기효능감 척도는 상담경험 수준

Purpose To investigate the value of the combined use of elastography and color Doppler ultrasonography (US) with B-mode US for evaluation of screening US–detected breast masses in women with dense breasts. Materials and Methods This prospective, multicenter study included asymptomatic women with dense breasts who were referred for screening US between November 2013 and December 2014. Eligible women had a newly detected breast mass at conventional B-mode US screening, for which elastography and c

Diffusion-weighted (DW) magnetic resonance imaging (MRI) is a rapid, unenhanced imaging technique that measures the motion of water molecules within tissues and provides information regarding the cell density and tissue microstructure. DW MRI has demonstrated the potential to improve the specificity of breast MRI, facilitate the evaluation of tumor response to neoadjuvant chemotherapy and can be employed in unenhanced MRI screening. However, standardization of the acquisition and interpretation

Video-assisted thoracoscopic surgery (VATS) has been known to be a stressful event for patients, and dexmedetomidine is known to attenuate surgery-induced sympathetic responses and potentiate analgesia in perioperative periods. The present was designed to evaluate the effects of intraoperative dexmedetomidine administration on the quality of recovery (QoR) and pulmonary function after VATS. Patients with lung cancer undergoing VATS were randomized to Dex group (loading of 1.0 μg/kg for 20 minute

Several studies suggest that delay in the surgical treatment of breast cancer is significantly associated with lower survival. This study evaluated the tumor growth rate (TGR) of invasive breast cancers during wait times for surgery quantitatively using ultrasonography (US) and identified clinicopathologic factors associated with TGR.This retrospective study was approved by our institutional review board and the requirement for written informed consent was waived. Between August 2013 and Septemb

본 연구는 상담자의 애착유형과 경험수준이 상담자의 공감능력에 어떤 영향을 미치는지를 밝히고자 하였다. 서울, 경기, 광주지역에서 상담 수련중이거나 상담심리사(1, 2급) 자격을 취득하고 상담사로 활동하고 있는 153명의 피검자들이 성인애착질문지, 정서적 공감 검사를 각각 평정하였다. 본 연구에서는 첫째, 상담자의 발달 수준에 따라 공감적 성향에 차이가 있는지, 둘째, 상담자의 애착유형이 공감능력에 미치는 영향을 상담수련경험이 중재하는지, 셋째, 상담자의 애착유형이 공감에 미치는 영향을 상담자의 발달 수준이 중재하는지를 확인하기 위하여 위계적 회귀분석을 실시하였다. 그 결과, 불안애착이 상담자의 정서적 공감에 유의한 영향을 미치는 것으로 나타났으며 애착유형과 상담경험의 상호작용 효과는 유의하지 않았다. 또한 상담수련경험과 상담자 발달수준은 애착유형이 공감에 미치는 영향을 중재하지 않는 것으로 나타났다. 즉, 상담자의 불안애착이 공감에 정적인 영향을 미친다는 것을 알 수 있었다. 이러한

The performance of radiologists in differentiating benign from malignant breast masses was improved when B-mode US was combined with two-view SWE compared with that when B-mode US was combined with single-view SWE.

Quantitative and qualitative SWE features reflect both the mechanical elasticity and histopathologic characteristics of breast cancers.

Background Breast density at mammography is an established risk factor for breast cancer, but it cannot be used to distinguish between glandular and fibrous tissue. Purpose To evaluate the association between the glandular tissue component (GTC) at screening breast US and the risk of future breast cancer in women with dense breasts and the association between the GTC and lobular involution. Materials and Methods Screening breast US examinations performed in women with no prior history of breast
