Disease relevance of Portography


High impact information on Portography

  • Carbon-dioxide portography: an expanding role [6]?
  • Probability of hepatocellular carcinoma of small hepatocellular nodules undetectable by computed tomography during arterial portography [7].
  • Partial splenic embolization was performed in two patients, direct shunt embolization was performed via percutaneous transhepatic portography in two other patients, and an MCS embolization was performed in one patient through the inferior vena cava [8].
  • PURPOSE: To compare findings at computed tomography (CT) enhanced with a hepatocyte-selective contrast agent (iodinated triglyceride) and/or iohexol and at CT during arterial portography (CTAP) [9].
  • Magnetic resonance imaging during arterial portography (MRAP) was performed by the authors in a selected group of 12 patients with hepatic lesions [10].

Chemical compound and disease context of Portography

  • This study was undertaken to compare the detection rate of hepatic space occupying lesion (SOL)s between computed tomography during arterial portography (CT-AP) and magnetic resonance imaging during arterial portography (MR-AP) and the differences in time intensity curve on MR-AP between HCC, metastatic tumor, FNH, and hemangioma [11].
  • PURPOSE: To assess the value of multidetector CT portography in visualizing varices and portosystemic collaterals in comparison with conventional portography, and to compare the visualizations obtained by three rendering models (volume rendering, VR; minimum intensity projection, MIP; and shaded surface display, SSD) [12].

Anatomical context of Portography


Associations of Portography with chemical compounds

  • Prostaglandin E1 as a pharmacoangiographic agent for arterial portography [20].
  • Intraarterial portography with gadopentetate dimeglumine: improved liver-to-lesion contrast in MR imaging [10].
  • MATERIALS AND METHODS: In 13 patients with HCC, chemoembolization was performed with injection of a mixture of iodized oil and doxorubicin hydrochloride followed by administration of gelatin sponge; 1-4 weeks later, TPEI was performed with percutaneous transhepatic portography [21].
  • Although the sensitivity of 18FDG PET (90%) was slightly lower than that of CT portography (97%), the specificity was much higher (100% versus 9%), including postsurgical sites [3].
  • This investigation suggests that both PGE1 and PGF2 alpha are effective for improved arterial portography, the latter agent appearing superior [22].

Gene context of Portography

  • On CT during arterial portography, the contrast enhancement indexes of HCCs showed moderate inverse correlation with the difference in the VEGF expression index (-0.51, p = 0.023) [23].
  • Magnetic resonance (MR) imaging with arterial portography (MRAP) was compared with computed tomography with arterial portography (CTAP) and conventional MR imaging for preoperative evaluation of hepatic masses in eight patients (nine studies) [24].
  • Moreover, in one patient, short gastric veins were not seen on conventional angiographic portography images of the spleen, but were clearly revealed on CT-MIP [25].
  • The stage of the primary tumor, disease free interval, preoperative carcinoembryonic antigen, computed tomography portography, intraoperative ultrasound, and assessment of intrahepatic and extrahepatic tumor extension were evaluated [26].
  • Our objective was to compare 3D contrast-enhanced MR portography (3D CE MRP) on a 1.5-T MR imager with direct X-ray portography [27].
