CT abdomen general
The general principles of the CT abdomen examination.
Normal Anatomy
Figure 5 lets you scroll through a normal abdominal CT in the portal venous phase. Unfortunately, not all organs can be discussed in detail in view of their complex anatomy.
A few characteristics of normal anatomy:
- Portal venous phase: the parenchyma of the liver/spleen/pancreas is homogeneously enhanced.
- Intra-abdominal fat has the density of fat (HU -50 to -100; see the X-ray/CT technique course for more information about Hounsfield units); similar to normal subcutaneous fat. If not, there may be ascites or fatty infiltration.
