OBJECTIVE To assess the feasibility and safety of polyvinyl alcohol (PVA) embolization adjuvant to transarterial oily chemoembolization (P-TACE) in advanced hepatocellular carcinoma (HCC) with arterioportal shunts (APS). MATERIALS AND METHODS Nineteen patients who underwent PVA embolization for APS before a routine chemoembolization (TACE) procedure were(More)
BACKGROUND Although pilomatricoma commonly occurs in children, there is still a poor understanding of the imaging characteristics of pilomatricoma and lack of agreement regarding its imaging findings and histopathologic features. OBJECTIVES To characterize the radiologic appearance of pilomatricomas on US, CT, and MR and to correlate the imaging findings(More)
OBJECTIVES To investigate the acute and repeated pulmonary damage in Sprague-Dawley rats caused by the inhalation of 3-methoxybutyl chloroformate (3-MBCF) using computed tomography (CT), and to correlate these results with those obtained from a pathological study. METHODS Sixty, 7-week-old rats were exposed to 3-MBCF vapor via inhalation (6 h/day) for 1(More)
OBJECTIVE Brown tumors are focal reactive osteolytic lesions that are encountered in patients with primary or secondary hyperparathyroidism, and these tumors have nonspecific magnetic resonance (MR) imaging findings. However, there are only a few reports on MR imaging of brown tumors. The purpose of this study is to describe the spectrum of MR imaging(More)
The authors describe a case of giant cell tumor (GCT) with secondary aneurysmal bone cyst (ABC) in a 44-year-old man with chronic, intermittent knee pain. A unique feature is the presentation of GCT with an ossified extraosseous soft tissue mass. Radiograph demonstrates a multiloculated lytic lesion in the distal meta-epiphyseal region of the femur with an(More)
BACKGROUND There are very few reports assessing in-stent restenosis (ISR) after vertebral artery ostium (VAO) stents using multidetector computed tomography (MDCT). PURPOSE To compare the diagnostic accuracy of computed tomography angiography (CTA) using 64-slice MDCT with digital subtraction angiography (DSA) for detection of significant ISR after VAO(More)
Accidental genital trauma is most commonly caused by straddle-type injuries and is usually treatable by nonoperative management, and most of the injuries have a good prognosis. When the bleeding occurred due to straddle injury in adolescent girl, experienced gynecological examination and treatment were very important. We experienced a case of straddle(More)
