OBJECTIVE The purpose of our study was to determine how frequently the right adrenal vein could be unequivocally identified on MDCT and the spectrum of anatomic variations seen in the right adrenal vein. MATERIALS AND METHODS Contrast-enhanced MDCT was performed in 104 patients with thoracoabdominal vascular disease using an 8-MDCT scanner. Both axial and(More)
Mucin-producing intraductal papillary neoplasm (adenocarcinoma/adenoma) in the bile duct is becoming recognized as a specific type of neoplasm. Since, it bears a striking similarity to intraductal papillary mucinous neoplasms of the pancreas with regard to its histopathologic features, the term "intraductal papillary mucinous neoplasms of the bile duct"(More)
PURPOSE To retrospectively assess the apparent diffusion coefficient (ADC) for prediction of malignancy and prognosis of malignant astrocytic tumors. MATERIALS AND METHODS The institutional review board approved this study and did not require patient informed consent. Findings from 37 consecutive patients (21 men, 16 women; mean age, 43 years) with(More)
Osteoclasts are derived from hematopoietic precursor cells belonging to the monocyte/macrophage lineage. Osteoclast development has been reported to be regulated by several molecules such as macrophage colony-stimulating factor (M-CSF), receptor activator of nuclear factor (NF)-kappaB ligand (RANKL), and a decoy receptor of RANKL, osteoprotegerin (OPG).(More)
Ascorbic acid (AA) is known to regulate cell differentiation; however, the effects of AA on osteoclastogenesis, especially on its early stages, remain unclear. To examine the effects of AA throughout the process of osteoclast development, we established a culture system in which tartrate-resistant acid phosphate (TRAP)-positive osteoclasts were induced from(More)
PURPOSE To preoperatively evaluate anatomic variations of the bronchial arteries by obtaining three-dimensional (3D) simulations with multidetector computed tomography (CT). MATERIALS AND METHODS This study was approved by the institutional review board, and written informed consent was obtained from all participants. Seventy-three consecutive patients(More)
We present two cases of adrenal hemangioma, a rare non-functioning adrenal tumor, and correlate the CT and MR imaging findings with the pathological findings. Peripheral spotty contrast enhancement with centripetal enhancement was noted in one case. This pattern of enhancement is crucial for diagnosing adrenal hemangioma. The other case showed only thin rim(More)
RATIONALE AND OBJECTIVES To study time-related magnetic resonance imaging (MRI) and histopathological findings after radiofrequency ablation (RFA) in the normal liver. METHODS Under ultrasound guidance, RFA was performed in 22 rabbits with a 15-gauge expandable probe inserted into the liver. The RF power was applied at 10 W initially with a 5-W increment(More)
