Tumor vascularity is an important indicator for differential diagnosis, tumor growth, and prognosis. Superb micro-vascular imaging (SMI) is an innovative ultrasound technique for vascular examination that uses a multidimensional filter to eliminate clutter and preserve extremely low-velocity flows. Theoretically, SMI could depict more vessels and more detailed vascular morphology, due to the increased sensitivity of slow blood flow. Here, we report the early experience of using SMI in 21 breast

Bronchial carcinosarcoma is a very rare malignant tumor that is composed of carcinomatous and sarcomatous elements. We describe the first case in which digital tomosynthesis was useful for the evaluation of airway obstruction by bronchial carcinosarcoma that was overlooked on initial chest radiography.

Purpose We aimed to develop a preoperative risk scoring system to predict early recurrence (ER) of intrahepatic cholangiocarcinoma (ICCA) after resection, utilizing clinical and computed tomography (CT) features.Materials and Methods This multicenter study included 365 patients who underwent curative-intent surgical resection for ICCA at six institutions between 2009 and 2016. Of these, 264 patients from one institution constituted the development cohort, while 101 patients from the other instit

목적: 일상적인 슬관절 자기공명영상에 포함된 축상영상의 반월판 열상 진단에 대한 정확도를 알아보고자 한다. 대상과 방법 : 임상적으로 슬관절의 반월판 열상을 의심하여 관절경 시술을 시행한 환자 중 수술 전 슬관절 자기공명영상 촬영을 시행한 환자 45명을 대상으로 하였다. 축상영상은 지방억제 양성자밀도강조영상을 사용해 얻었으며 절편두께와 간격은 모두 4 mm이었다. 총 45명 환자의 내측, 외측 반월판 90개의 자기공명영상을 2명의 영상의학과 의사가 후향적으로 분석하였으며 반월판 열상의 진단은 각 슬관절 자기공명영상의 축상영상만으로 진단을 하였다. 관절경에서의 반월판 열상 소견을 기준으로 하여 축상영상에서 판독한 반월판 열상의 존재 여부와 열상의 위치가 일치한 경우에 대한 민감도, 특이도, 양성 예측도, 음성 예측도, 정확도를 계산하였다. 결과: 총 45명의 환자에서 총 90개의 반월판을 관절경 시술로 확인하였다. 동시에 양측 반월판 열상을 앓고 있었던 2명을 포함하여 반월판 열상 환

Malignant extrarenal rhabdoid tumor (MERT) is a very aggressive tumor that is extremely rare in adults. Herein, we introduce three cases of MERT in adults that originated in the ileum, adrenal gland, and uterine endometrium. The MERTs in the ileum and adrenal gland showed non-aggressive features and a good prognosis, while the MERT in the uterine presented with aggressive features and distant metastasis.

Among exocrine pancreatic tumors, adenosquamous carcinoma is a rare, aggressive subtype with a poor prognosis and a high potential for metastases compared with its more conventional glandular counterpart, adenocarcinoma of the pancreas. We herein describe the imaging findings of pancreatic adenosquamous cell carcinoma with solitary liver metastasis showing different imaging features and also review the previous literature to recognize characteristic imaging features of pancreatic adenosquamous c

Solitary fibrous tumor (SFT) is a rare neoplasm, which is usually presented as a pleural based mass, but can also occur in unusual locations based on its mesenchymal origin. However, the radiologic features of SFT occurred in the ischiorectal fossa have been rarely reported. In this case, we describe the MRI findings in a case of a SFT involving the ischiorectal fossa of a 36-year-old man. The tumor appeared as homogeneous iso-signal intensity relative to the adjacent muscle on T1 weighted image

The subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) technique is reportedly effective in severe peripheral vascular disease that cannot be treated with standard endovascular techniques including subintimal angioplasty. In this report, we used a target balloon with the Outback catheter to recanalize a thrombosed bypass graft that could not be treated successfully with SAFARI.
