Contrast-enhanced MR angiography in rats with hepatobiliary contrast agents.

The aim of this animal study was to evaluate the feasibility of contrast-enhanced magnetic resonance (MR) angiography with two hepatobiliary contrast agents, Gd-DTPA-DeA and Gd-EOB-DTPA. Coronal images of the rat abdomen were acquired using a three-dimensional spoiled gradient recalled sequence before and after the administration of Gd-DTPA-DeA, Gd-EOB-DTPA, or Gd-DTPA. Four sets of postcontrast images were collected every 90 s.

Interstitial magnetic resonance lymphography: comparative animal study of gadofluorine 8 and gadolinium diethylenetriamine-pentaacetic acid.

Purpose: We evaluated the usefulness of gadofluorine 8 (G8) and gadolinium diethylenetriamine-pentaacetic acid (Gd-DTPA) for interstitial magnetic resonance lymphography (MRL).

Method: Phantom imaging studies were conducted with G8 and Gd-DTPA corresponding to 0.1-0.

Phantom and animal studies of a new hepatobiliary agent for MR imaging: comparison of Gd-DTPA-DeA with Gd-EOB-DTPA.

Purpose: To investigate the characteristics of Gd-DTPA-DeA as a hepatobiliary contrast agent for MR imaging in comparison with those of Gd-EOB-DTPA.

Materials And Methods: We undertook phantom experiments to assess T1 relaxivity for Gd-DTPA-DeA, Gd-EOB-DTPA, and Gd-DTPA in human plasma. For Gd-DTPA-DeA and Gd-EOB-DTPA, we evaluated the contrast effect in rats using an SPGR sequence.

Fitz-Hugh-Curtis syndrome: linear contrast enhancement of the surface of the liver on CT.

We present a case of Fitz-Hugh-Curtis syndrome (Chlamydia trachomatis perihepatitis). Contrast-enhanced CT demonstrated enhancement along the surface of the liver, but it was remarkable on the anterior surface. No other abnormalities suspicious for peritonitis were found.
