#Health 2022 #MR Flat Scan and Enhancement for Partial Differentiation of Liver Tumors.
Elderly men, liver discomfort, normal AFP, CA199 value: 280 or more, ultrasound indicates liver mass, to the imaging department to perform MR flat scan + enhancement. The left lobe of the liver shows a large mass-like abnormal signal, about 12x7 cm in size.
Figure 1, T2WI lipid pressure image and T2WI show a significant high signal, considering the light sign, see here basically has a spectrum, DWI is high signal, inverted phase signal is not reduced.
Figure 2, shown by the red arrow.
Figure 3, flat sweep + enhancement, T1WI, arterial stage, portal phase, equilibrium phase, visible tumor showing uniform low signal, enhanced arterial phase marginal punctate strengthening, portal phase and equilibrium phase strengthening centripetal, filling, and significant strengthening.
Multiple hemangiomas are diagnosed, and other conditions are not shown.
When the tumor marker suggests abnormality, ultrasound suggests a mass lesion, liver tumor is best MR flat scan + enhance identification, many can clearly diagnose benign tumors, regular review can be, no need to pay too much attention.
Because although the tumor marker is sensitive, but the specificity is not high, MR flat sweep + enhancement, basically can clarify the benign and malignant nature of the tumor, especially the gadolinium contrast agent MagenWeixian compared with the Pumeixian, Pumeixian has a natural discriminating ability for malignant tumors, of course, the price is also super beautiful, the difference is ten times. If a liver tumor is suspected, choose MR flat scan + enhancement (preferably selected general beauty), which can be basically qualitative.
Liver benign and malignant tumor identification point, normal liver parenchyma 80% portal vein blood supply, 20% hepatic artery blood supply, liver malignant tumors, basically hepatic artery blood supply, arterial phase strengthening has a certain suggestive significance, to consider malignant tumors, but some benign tumors are also strengthened, need portal phase and balance phase further examination; Pumei Xian is a negative contrast agent, there is a special hepatobiliary specific stage, hepatocyte normal absorption, and malignant tumors, hemangiomas, cysts without normal hepatocytes, do not absorb contrast agent, low uptake, It is shown as a defect, the contrast is obvious, and the tumor nature can be determined by combining flat sweep + ordinary enhancement.
If you can do it, you won't do it.
