ILD Patterns vs PreOp

ILD Patterns puts the 2025 ERS/ATS interstitial pneumonia classification in your pocket — built for pulmonologists, pulmonary fellows, residents, radiology trainees, and medical students who want fast, structured HRCT morphology study without digging through PDF tables. Use the pattern analysis tool or the Pattern listing descriptions on-the-go. Medical education and 2025 guideline-based educational referencing. EDUCATIONAL USE ONLY — NOT FOR PATIENT DIAGNOSIS This app is for professional education and self-study. It is NOT medical advice, NOT software as a medical device (SaMD), NOT clinical decision support, and NOT intended for patients. Outputs are educational morphology suggestions only. PATTERN TOOL — EDUCATIONAL RANKING ENGINE • Select HRCT imaging features across six ABCDEF groups (distribution, density, signs, and more) • Generate an educational ranked morphology differential across major interstitial patterns and rare alveolar-filling patterns (Table 2 + Supplementary Table S2) • Tap any result for a detail sheet: supporting features, features arguing against, Table 1 associated diagnoses, pathology excerpts, and Table 4 combined-pattern references • Review educational fit badges, conflict cautions, combined morphology notes, and an anchor eligibility checklist • Ideal for fellows learning systematic ILD review, residents on pulmonary rotations, and attendings teaching pattern recognition PATTERN LIST — FULL GUIDELINE REFERENCE LIBRARY • Browse verbatim ERS/ATS 2025 tables: UIP, NSIP, BIP, DAD, PPFE, LIP, organising pneumonia, RB-ILD, AMP, and rare alveolar-filling patterns (PAP, eosinophilic pneumonia, lipoid pneumonia) • Clinical, radiological, and pathological columns plus Table 1 secondary and primary diagnoses • Table 3 organising pneumonia subpatterns (OP, AFOP, CiOP) • Table 4 combined radiological-histological patterns with common differential diagnoses • Free tier includes a sample of entries; Premium unlocks all 22 expandable reference cards WHO IT'S FOR • Pulmonologists and pulmonary fellows building fluency with the 2025 classification • Internal medicine and pulmonary residents on ILD rotations • Medical students learning HRCT morphology vocabulary • Radiology trainees aligning pattern language to ERS/ATS tables • Educators preparing teaching sessions, M&M discussions, or board-style review FREE & PREMIUM FREE INCLUDES: • 5 educational pattern interpretations (Pattern Tool) • Sample Pattern List entries to explore the guideline library ILD PATTERNS PREMIUM: • Unlimited educational pattern rankings • Full Pattern List — every morphology entry, OP subpattern, and combined-pattern group • Restore purchases on the same Apple ID PRIVACY BY DESIGN • No logins • Rankings stay on your device; developer does not collect feature selections or analytics GUIDELINE SOURCE Ryerson CJ, Walsh SLF, Sverzellati N, et al. An update of the international multidisciplinary classification of the interstitial pneumonias. Eur Respir J. 2025;66:2500158. IMPORTANT LIMITATIONS Outputs are educational morphology suggestions based only on user-selected imaging features. They may be incomplete or incorrect. Educational rankings do not replace multidisciplinary discussion, radiology or pathology review, institutional protocols, or independent clinical judgement. Numeric scores are an educational approximation of qualitative guideline language and have not been validated against patient cohorts. Fit badges reflect educational morphology alignment — not ERS/ATS multidisciplinary diagnostic confidence percentages. SUBSCRIPTION TERMS Payment charged to your Apple ID at confirmation.

Prepare for surgery with a structured clinical reference at your side. PreOp brings preoperative assessment, risk calculators, perioperative medication references and handoff tools into one app for anesthesiologists, surgeons, internists, hospitalists and residents. ASSESS AND ORGANIZE Review cardiac, airway, metabolic and medication considerations in a readiness dashboard. Organize issues to discuss with your team, explore optimization pathways and review investigation suggestions with supporting rationale. Readiness flags support assessment; they are not clearance for surgery. EXPLORE CLINICAL CALCULATORS Access tools including RCRI, STOP-BANG, Caprini VTE, ARISCAT and Apfel, alongside BMI, eGFR and anion gap. Review the context and limitations of each result rather than relying on a score alone. REVIEW MEDICATIONS AND NEURAXIAL TIMING Find perioperative medication references covering anticoagulants, antiplatelets, diabetes treatments and other drug groups. Review neuraxial timing considerations with cited guidance, including ASRA 2025. Suggested intervals do not guarantee safety: confirm dose, renal function, patient factors and local protocols. PLAN POSTOPERATIVE CARE Build a structured plan covering medication restart considerations, VTE prevention, monitoring, glucose management, OSA, delirium and pain or nausea management. Review and adapt every output before clinical use. COMMUNICATE WITH YOUR TEAM Prepare I-PASS and SBAR handoff drafts, problem lists and summaries. Organize a morning board with pending actions, and work through a perioperative safety checklist. REFERENCE AND LEARN Explore source-linked clinical content and learning material. Clinical reference content is available offline, with light and dark themes for supported screens. Internet is required for purchases, restoration and access-code activation. FREE AND PREMIUM ACCESS Start with the basic assessment, learning content and free calculators including BMI, eGFR and anion gap. Premium unlocks the full set of tools. A valid Oman annual access code provides full access for its named calendar year, ending at midnight on January 1 of the following year in Oman time. IMPORTANT CLINICAL INFORMATION PreOp is a reference and decision-support aid for qualified healthcare professionals. It does not replace clinical judgment, specialist consultation, institutional protocols or independent verification. Calculator results and generated plans must be checked against the individual patient's circumstances. Do not use PreOp as the sole basis for diagnosis, prescribing or procedural decisions. PreOp Premium: US$2.49/month or US$29/year in the US, effective October 4, 2026. Localized prices vary; the checkout price applies. Payment is charged to your Apple ID account at confirmation.
