Calculators for radiology practice

Small calculators and tools for daily reporting, running right in the browser — no install required.

Apps open on alvaro-menezes.com in a new tab. Usage guidance ↗

ASPECTS: regional ischemic stroke assessment

Includes noncontrast CT ASPECTS, DWI-ASPECTS and pc-ASPECTS in separate modules. An interactive CT, T1 and DWI atlas accompanies manual regional assessment and shows deducted points. Includes teaching examples, indeterminate findings, references and Portuguese/English RIS/PACS text, with mobile and offline use. Outlines are educational; the score alone does not determine treatment eligibility.

Open ASPECTS

DemênciaRM: structured brain MRI and CT assessment

Combines MTA, Fazekas, GCA, Koedam, ARWMC, van Swieten and other markers in a structured assessment. Includes published and licensed MRI examples, labelled diagrams, modality-specific criteria and an editable report in Portuguese and English. Examination data remain only in the open session; the scales quantify findings and do not independently define dementia etiology or clinical stage.

HemoRad: periprocedural bleeding assessment

Organises the procedure, target organ, bleeding history, medications and laboratory results into an assessment pathway for interventional radiology. Shows baseline procedural risk, missing information and suggested action, with sources and optional complements. Prototype for professional review, without clinical validation: it does not estimate an individual bleeding probability or clear the procedure.

Puberty Calc: pediatric pelvic ultrasound

Combines age, menarche history and transabdominal female pelvic measurements. Calculates volumes and the fundus-to-cervix ratio, offers a descriptive estimate of pubertal morphology and generates a draft report with a conclusion. Criteria and limitations are explicit; the tool does not diagnose precocious puberty or assign a Tanner stage. The interface and report are available in Portuguese and English.

Open Puberty Calc

GFR: kidney function calculator

Estimates glomerular filtration rate from creatinine and the inputs required by each equation. Includes CKD-EPI 2021, CKiD U25 and Schwartz, with method selection according to age. References and limitations for each estimate are available in the app.

Open GFR

TI-RADS: thyroid nodules

Organises thyroid nodule ultrasound findings using ACR TI-RADS. Review the score, category and guidance related to the measurements and context entered, and prepare a description for professional review.

Open TI-RADS

HepFe: liver iron by MRI

Analyses signal decay in MRI measurements to estimate liver iron. Provides curve fitting, calibration selection and export of a plot and text for review. Interpretation depends on the acquisition, the chosen model and its limitations.

Open HepFe*

O-RADS: ovarian and adnexal lesions

Helps organise descriptors for an adnexal lesion on ultrasound or MRI using ACR O-RADS. The app presents the category, references and draft report text for review, with attention to the imaging modality and applicable clinical context.

Open O-RADS Calc

N-Lung: pulmonary nodules on CT

Separates incidental nodule assessment using Fleischner recommendations from screening assessment using Lung-RADS. Brings together measurements, examination comparison and draft report text for review. Check the eligibility criteria before using each system.

About RadApps

Medical knowledge.
Digital experience.

RadApps brings together radiology and software development. Our purpose is to translate practical needs into clear, accessible and useful tools.

Created by a radiologist.

An initiative by Dr. Álvaro Menezes, a radiologist and full member of the Brazilian College of Radiology, practising general and musculoskeletal radiology.

Independent development based in Fortaleza, Brazil, with a visual language and experiences designed for professionals across borders.

Frequently asked questions

Before you
get started.

The essentials of access, availability and responsible use.

Who are the apps for?

They are intended for radiologists and other healthcare professionals familiar with each tool’s purpose and limitations. They are not a patient diagnostic service.

Do I need to install anything?

The five featured apps are accessible in a browser. Links open their original pages on alvaro-menezes.com in a new tab.

Are they on the App Store and Google Play?

This site presents the iOS, Android and web development initiative. Currently, the published links lead to web versions. Official store links will be added when releases are available.

Can I send examinations or patient data?

The RadApps website has no upload feature, medical record system or clinical form. Do not send identifiable patient data through the contact channel. Read each app’s own policy before entering information.

How do I report a problem or suggest an improvement?

Email [email protected] with the app, device, browser and steps to reproduce the issue, without patient data.
