PURPOSE To evaluate whether mangafodipir trisodium (Mn-DPDP)-enhanced magnetic resonance (MR) imaging surpasses dual-phase spiral computed tomography (CT) in differentiating focal liver lesions. MATERIALS AND METHODS One hundred forty-five patients who had or were suspected of having focal liver lesions were included in a multicenter study and underwent dual-phase spiral CT and enhanced MR im...

Traumatic rupture of the diaphragm (TRD) poses a challenge to both radiologists and surgeons. They are uncommon and occur following blunt abdominal or lower thoracic trauma. The right side involvement is less common than the left side and is easily missed. Spiral computed tomography (Spiral CT) with image reformation is very useful in the diagnosis of TRD and in identifying associated injuries....

We report a case of primary gastrointestinal stromal tumor (GIST) of the liver. A 17-year-old man with a solid mass in the anterior segment of the right liver was asymptomatic with negative laboratory examinations with the exception of positive HBV. Contrast-enhanced ultrasound (CEUS) revealed a hypervascular lesion in the arterial phase and hypoechoic features during the portal and late phases...

Nonlinear dynamics of the spiral Poiseuille problem for moderate axial through flow is investigated numerically within the corotating regime for medium gap geometry. The neighborhood of a double Hopf bifurcation point of the linear stability boundary, where spiral waves of opposite axial phase propagation compete, is explored by accurately solving time-dependent Navier-Stokes equations with a s...
