MRDEEP DIVE AIPractical tools for MRI

WEIGHT → VOLUME · U.S. LABEL REFERENCE

MRI contrast,
with the units clear.

Convert weight and height. See product-specific dose volumes.
Keep your facility’s protocol alongside the label.

Adults 18+ · Intravenous use only

01 / START WITH WEIGHT

Patient weight

20 mL site-rule cap ON. Uncheck to turn it off.

CONVERTED WEIGHT
— kg

1 lb = 0.45359237 kg

Full precision is used in calculations.
Weight is not saved or included in exports.

HEIGHT CONVERTER

Feet + inches → centimeters

Use whole feet and 0–11.99… inches. Fractional inches are supported; an empty field counts as 0.

CONVERTED HEIGHT
— cm

1 inch = 2.54 cm · 1 foot = 30.48 cm

Height is not saved or included in exports.
Height does not affect the contrast dose calculation.

02 / LABEL-BASED REFERENCE

Eight brands. Product-specific math.

These cards are not a list of interchangeable agents. Read each card’s indication. Volumes are approximate displays to 3 decimal places; no syringe rounding is applied. The 20 mL site-rule checkbox is ON by default. When it limits a result, the uncapped label volume is shown underneath.

03 / YOUR FACILITY

Local protocol profiles

Save your facility’s specific rule, optional mL cap, and exam notes. These are user-entered protocols, not manufacturer recommendations. Only profiles—not patient weights—are stored in this browser. Clearing browser data removes them.

Choose or save a profile to compare its calculation with the label.

A profile’s cap applies to its facility calculation first; the 20 mL checkbox then limits that result further when enabled. Uncapped U.S. label values remain visible separately. No built-in profile is claimed to be approved by your facility. Import adds profiles; export first if you need a backup.

How the calculation works

Convert weight

kg = lb × 0.45359237

Calculate volume

mL = kg × mmol/kg ÷ mmol/mL

Keep rules separate

Local mL = dose rule, then optional profile cap, then the 20 mL site rule when enabled.

Reference doses and concentrations checked against the linked U.S. prescribing information on October 16, 2026. This is a static reference; labels are not refreshed automatically. Product availability and formulary use vary. The eight brands are a starting selection, not a market-share ranking or a complete catalog.

Before clinical use, your facility should independently validate the calculations and entries. Software testing does not establish clinical validation. Full prescribing information includes administration, handling, screening, contraindications, and warnings beyond this calculator.

04 / DISCLAIMER & SOURCES

Site-specific dosing & prescribing information

All contrast dosing is site-specific. Follow your facility’s approved protocol. The 20 mL cap is a configurable site rule, not a universal manufacturer maximum.

A dose reference, not an administration order. Confirm the contrast, concentration, indication, current label, and authorized protocol. This tool does not assess renal function, allergy, pregnancy, or clinical suitability. GBCAs have serious warnings, including NSF and risks from intrathecal use. Review the linked prescribing information. Pediatric, cardiac split-dose, supplemental, oral, intra-articular, and intrathecal dosing are outside this version.

Dose factors, concentrations, and supported indications come from the following U.S. prescribing-information pages on DailyMed, National Library of Medicine. Reference check: October 16, 2026. Facility profiles and the optional 20 mL rule are user-defined and are not sourced manufacturer limits.
