ImagingGuide vs MRI Toolkit

ImagingGuide helps physicians and medical students select the most appropriate imaging study for any clinical scenario, based on the official ACR Appropriateness Criteria®. Choose a body area, answer a few clinical questions, and instantly see ranked imaging recommendations — organized by appropriateness (Usually Appropriate / May Be Appropriate / Usually Not Appropriate) and radiation level. • Covers 3,900+ clinical scenarios across all major specialties • Adult and pediatric modes • Works completely offline — no account needed • Search any scenario directly from the home screen • Save favorites and revisit recent scenarios Based on guidelines published by the American College of Radiology. Always apply clinical judgment.

MRI Toolkit brings practical MRI learning and protocol calculations into one focused app for MRI students, technologists, and imaging professionals. Learn basic MRI physics in plain language, calculate voxel dimensions, estimate scan time, explore protocol tradeoffs, and compare common manufacturer sequence acronyms. INCLUDED TOOLS • Basic MRI Physics Follow the journey from proton alignment and RF excitation to relaxation, signal detection, gradients, k-space, SNR, and spatial resolution. • Voxel Calculator Compare 2D and 3D voxel dimensions and volume using FOV, matrix, slice thickness, slab coverage, and slice/partition thickness. • Scan Time Calculator Estimate acquisition time and review timing relationships using TR, phase matrix, NEX, echo train length, TE, TI, and bandwidth. • Protocol Optimizer Explore balanced, resolution, SNR, or scan-time goals and compare current parameters with educational suggestions and clearly stated tradeoffs. • Sequence Acronyms Cross-reference common Siemens, GE, Philips, and Canon names for related MRI sequence families. OPTIONAL LEARNING MODULES Explore free previews of Contrast, Timing and Sequences; MRI Acceleration; Artifacts and Image Quality; and Bandwidth Deep Dive. Unlock each complete module with a one-time in-app purchase. An optional Artifacts + Bandwidth Bundle unlocks both Modules 4 and 5. Restore Purchases is available for previously purchased content. PRIVACY FIRST MRI Toolkit requires no account and contains no advertising, tracking, or third-party analytics. Calculator inputs remain on the device. EDUCATIONAL USE MRI Toolkit is an educational reference and calculation aid. Calculations are simplified estimates. The app does not diagnose, treat, prevent, or monitor medical conditions and does not replace scanner documentation, institutional policy, device labeling, MRI safety procedures, or qualified clinical judgment.
