Right Lobe Function

|LIVER |

Caudo ~ Cranial (CC) length = < 17 cm

Right Lobe

Caudo ~ Cranial (CC) length = < 16 cm
Anterio ~ Posterior (A ~ P) length = < 16 cm

Left Lobe

Width = < 11 cm
Anterio ~ Posterior (A ~ P) length = < 7 cm

Caudate Lobe

Caudo ~ Cranial (CC) length = < 8 cm (5 ~ 8 cm)
Anterio ~ Posterior (A ~ P) length = < 2.5 cm (2.0 ~ 2.5 cm)

Caudate lobe and Right lobe ratio (cc length of caudate lobe/ cc length of right lobe)

> 0.65 = 93 % specific for cirrhosis
> 0.73 = 99 % specific for cirrhosis

Normally Right lobe : Caudate lobe = 3 : 2

Pediatric liver size (up to 12 years) = <
Normal renal pelvic diameter in fetus

▪ 15 ~ 20 weeks = < 4 mm ▪ 20 ~ 30 weeks = < 8 mm ▪ > 30 weeks = < 10 mm

Prostate

Measurement of weight = L X W X A~P X 0.55 (expressed in gm)
Normal weight = < 30 gm
(If any measurement appears more than 37 mm, it assumes prostate is enlarged)

Urinary bladder

Normal wall thickness = 3 mm (in distended
In pre-menopausal women ▪ In proliferative phase = 2 ~ 8 mm ▪ During ovulation = 13 mm ▪ Secretory phase = 8 ~ 14 mm

b. In postmenopausal women ▪ With hormone therapy = < 8 mm ▪ Without hormone therapy = < 5 mm
Endometrial hyperplasia

Endometrial thickness = > 14 mm (in pre-menopausal women) = > 8 mm (in postmenopausal women)
