The presence of AFP, a plasma protein normally produced by the fetus, in the mother’s blood. The MSAFP serves as the basis for some valuable tests. AFP is manufactured principally in the fetus’s liver and, also, in the fetal gastrointestinal (GI) tract and the yolk sac, a structure temporarily present during embryonic development.

Minimal residual disease, evidence for the presence of residual malignant cells, even when so few cancer cells are present that they cannot be found by routine means. Tests for minimal residual disease (MRD) can detect some early tumors. In a patient who has been treated, the detection of MRD indicates that treatment is incomplete. MRD can thus distinguish who…

Magnetic resonance cholangiopancreatography, an application of MRI (magnetic resonance imaging) to the hepatobiliary and pancreatic system. An MRCP uses an MRI machine with special software to obtain images comparable to the cholangiogram and pancreatogram obtained by the more invasive approach with ERCP (endoscopic retrograde cholangiopancreatography) without the added risks of sedation, pancreatitis, and perforation. MRCP may be useful, for example,…

The magnetic resonance angiogram, or MRA, is a noninvasive test that has demonstrated usefulness in defining the anatomy of blood vessels of certain size in the head and neck. MRA serves as a complement to traditional MRI scanning in evaluation of the brain and neck. Conventional angiograms, whereby contrast material is injected through a catheter into the blood vessels of the…
