Ductal carcinoma in situ (DCIS) accounts for 20%-25% of breast cancers detected at screening mammography. The lesions are diverse and commonly are classified on the basis of their mammographic features and histologic characteristics such as nuclear grade and presence or absence of necrosis. The most common mammographic finding in DCIS is(More)
PURPOSE To evaluate the incidence of supernumerary renal arteries in horseshoe kidney (HSK) patients, focusing on number and diameters using computed tomographic angiography (CTA). MATERIAL AND METHODS Thirty-nine patients with HSK and 103 patients with normal kidney (NK) underwent 64 or 128 multidetector CT. Based on 2-dimensional CT, including(More)
PURPOSE To evaluate the correlation between apparent diffusion coefficient ( ADC apparent diffusion coefficient ) values and the Ki-67 labeling index for luminal-type (estrogen receptor-positive) breast cancer not otherwise specified ( NOS not otherwise specified ) diagnosed by means of biopsy. MATERIALS AND METHODS The institutional review board approved(More)
To evaluate whether apparent diffusion coefficient (ADC) parameters could identify invasive components in cases with ductal carcinoma in situ (DCIS) diagnosed by biopsy. This retrospective study was approved by the institutional review board and the requirement to obtain informed consent was waived. Sixty-nine consecutive women with 70 lesions diagnosed(More)
To evaluate whether visual assessment of T2-weighted imaging (T2WI) or an apparent diffusion coefficient (ADC) could predict lymphovascular invasion (LVI) status in cases with clinically node-negative invasive breast cancer. One hundred and thirty-six patients with 136 lesions underwent MRI. Visual assessment of T2WI, tumour-ADC, peritumoral maximum-ADC and(More)
OBJECTIVE The purposes of this study were to evaluate diagnostic parameters measured with ultrafast MRI acquisition and with standard acquisition and to compare diagnostic utility for differentiating benign from malignant lesions. MATERIALS AND METHODS Ultrafast acquisition is a high-temporal-resolution (7 seconds) imaging technique for obtaining 3D(More)
Here we report a case of uncontrollable chylous ascites that developed after nephrectomy and was successfully treated with percutaneous obliteration of the lymphocele-like extravasation using ethiodized oil during lymphangiography. Under computed tomographic and fluoroscopic guidance, an N-butyl cyanoacrylate–ethiodized oil mixture was used with metallic(More)
The aim of this study is to evaluate the correlation between multidetector row helical computed tomography (MDCT) findings and the histopathological characteristics of patients with invasive ductal carcinoma. We retrospectively reviewed MDCT findings and the corresponding histopathological features of 442 women with invasive ductal carcinoma. We received(More)
Cholangiolocellular carcinoma (CoCC) is a rare primary liver cancer. It is considered to originate from hepatic progenitor or stem cells. We report a rare case of a 74-year-old male with CoCC of the liver and duodenal gastrointestinal stromal tumor (GIST). Both tumors manifested tracer uptakes on F-18 fluorodeoxyglucose positron emission tomography/computed(More)
Our aim was to assess the usefulness of a new magnetic resonance imaging (MRI) finding, the placental recess, for diagnosing placental invasion. This retrospective study included 51 patients (mean age 34.1 years, range 26–43 years) with suspected placental invasion who underwent cesarean section. Preoperative MRI was performed using a 1.5-T unit and(More)
