The unenhanced spin-echo T1-weighted images, contrast-enhanced (dynamic and conventional) T1-weighted images and spin-echo T2-weighted images of 19 patients with histologically proven intrahepatic cholangiocarcinoma were reviewed. The results showed that typical intrahepatic cholangiocarcinoma presented as a large mass of low signal intensity on T1-weighted(More)
PURPOSE To evaluate spin-echo and contrast material-enhanced dynamic magnetic resonance (MR) imaging in characterization of thyroid and parathyroid masses. MATERIALS AND METHODS Conventional T1- and T2-weighted, gadolinium-enhanced dynamic, and gadolinium-enhanced T1-weighted spin-echo imaging sequences were performed in 85 patients with thyroid and(More)
Gelatin sponge particles were rendered radiopaque by soaking them in small amounts of iodized oil (LP-GS). They were evaluated for their usefulness in transarterial embolization (TAE). The LP-GS particles were well visualized fluoroscopically during TAE. The duration of the opacity of LP-GS exceeded 24 hours both in vitro and in vivo. LP-GS are useful, and(More)
Wilms' tumor is an uncommon disease in adults. Wilms' tumor typically presents as a large complex mass with cystic component and varying degrees of vascularity. The previously reported radiologic findings have reflected this complex appearance. We present a case of cystic Wilms' tumor in an adult patient. The tumor presented as a large, rapidly growing,(More)
PURPOSE The purpose of this study was to evaluate the effects of selected parameters in a conventional spin-echo MRI sequence on image quality in a phantom undergoing periodic motion. METHODS Images of a composite oil/copper sulfate phantom moving in a 1.5 Tesla magnet were acquired. The CuSO4 ghost signal-to-noise ratio (SNR) and distances between(More)
PURPOSE To clarify the characteristics of the defects on computed tomography (CT) during arterial portography (CTAP) due to arterio-portal shunting (APS). METHOD AND PATIENTS The defects in the hepatic parenchyma on CTAP due to angiography proven APS were characterized according to their configuration, size, sharpness of margins, location of the lesion in(More)
We present a patient with renal artery stenoses due to fibromuscular dysplasia involving the point of arterial bifurcation that we could successfully dilate with percutaneous transluminal angioplasty. We used the kissing balloon technique to prevent possible complications of percutaneous transluminal renal angioplasty (PTRA), including occlusion of the(More)
