1. Formula for Splenic volume on CT: 30 + 0.58(Width x Length x Thickness)
2. Formula for Splenic volume on Ultrasound: 0.524 × Width on transverse sonogram × Thickness on transverse sonogram × (Maximum length on longitudinal sonogram + Craniocaudal length on longitudinal sonogram ) / 2.
3. Reference:

What is normal spleen size on ultrasound?

Normally, the spleen does not extend inferior to the left costal margin; hence a normal spleen is seldom palpable through the anterolateral abdominal wall. It varies in size and shape but it is usually 12 cm long, 5 cm thickness, and 7 cm wide.

How do you measure spleen volume?

1. Splenic index = L x D x T. A normal value is considered ≤480.
2. Volume [mL] = 30 + 0.58 x L x D x T. A normal value is considered between 110 and 340mL.
3. Weight [g] = 1.05 x volume.

What is the normal size of a healthy spleen?

The size of a normal, healthy spleen can vary considerably from person to person. Your sex and height can also affect its size. In general, an adult spleen is about 5 inches long, 3 inches wide, 1.5 inches thick, and weighs about 6 ounces.

What is the normal splenic index?

The normal splenic index (product of the length, width, and thickness) ranges between 120 and 480 cm3 [8]. Ultrasound is the most commonly and widely used modality for assessing the spleen [9–12].

How do you measure spleen index?

The splenic index is calculated using the equation V = 30 + 0.58⋅D⋅L⋅H, where depth (D), length (L), and height (H) are two-dimensional measurements of the spleen in the axial or coronal plane.

What is the normal size of spleen in MM?

The normal spleen length for adults in this study ranged from 76 mm to 131 mm and has a strong positive correlation with subject height (r = 0.990, P < 0.001) and also correlates with weight (r = 0.283 P < 0.001).

What size should my spleen be?

Is a 9 cm spleen normal?

Currently, the literature states that 95% of adult spleens are less than 12 cm (9,12–15) or even 11 cm (16) in length.
