There are mainly three planes of the body used for plain film imaging and cross-sectional imaging. All three planes are mutually right-angled to each other.
1. Coronal plane: divides the body into anterior to posterior
2. Axial plane or transverse plane: divides the body into superior and inferior
3. Sagittal plane: divides the body into left and right part
1. The right hypochondrium region contains liver, gall bladder, right kidney, small intestine.
2. The left hypochondrium region contains spleen, colon, left kidney, and pancreas.
3. The epigastric region contains the stomach, duodenum, liver, pancreas, adrenal gland.
4. The left lumbar region contains gall bladder, liver, and right colon.
5. The right lumbar region contains a descending colon and left kidney.
6. The umbilical region contains the umbilicus, jejunum, ileum, and duodenum.
7. The right iliac region contains ilium and caecum.
8. The left iliac region contains descending colon and sigmoid colon
9. The hypogastric region contains urinary bladder, sigmoid colon.
There are four quadrants:
1. The right upper quadrant contains the right kidney, gall bladder, colon, and pancreas.
2. The left upper quadrant contains the stomach, left kidney, spleen, pancreas.
3. The right lower quadrant contains the appendix, colon, small intestine, ureter, major vein and artery to the right leg.
