Comparative Pharmacokinetic Behavior of Levovist with Water-Soluble Contrast Agents,capillaries in the body. It is known that water-soluble contrast agents leak into the extravascular inter-stitium during the delayed phase, which may result in the false-positive diagnosis of fibrotic changes. However, the dynamic behavior during the 2–3 min from early to late phase is generally described as free pass.

Contrast Imaging (Toshiba PowerVision 8000 and Aplio),h of them provides the most useful diagnostic findings. This chapter describes the optimal contrast mode of the PowerVision series for contrast imaging, mainly using Levovist. The features of next-generation contrast agents are also described with regard to both engineering and clinical practice.

The Role of Contrast-Enhanced Ultrasonography in the Diagnosis and Treatment of Hepatic Tumors (Sum aid of other diagnostic imaging methods or histological examination. In this sense, the first major role of contrast-enhanced US can be to diagnose a benign tumor for outpatients, avoiding further invasive examinations, such as biopsy or angiography.

Principles of Harmonic Imaging,illaries in the lungs, and therefore can be no larger than about 8 μm in diameter. Because of this limitation, the scattering intensity obtained with these microbubbles is not high enough to visualize blood flow easily by conventional B-mode imaging.

Pulse Inversion Harmonic Imaging (ATL HDI 5000),reatly distorted. Waveform distortion means the generation of harmonic signals, which are several integral times larger than those of the transmitted frequency (Fig. 12–2). Those signals at the double transmitted frequency are known as second harmonics.

Application of Contrast-Enhanced Harmonic Imaging in Biliary and Pancreatic Tumors,he event of a malignant tumor, such as gallbladder cancer, it is known that large vessels directly flow into the tumor. Therefore, intraarterial contrast-enhanced US is useful in differentiating a benign from a malignant lesion.
