Integrates PI-RADS v2.1, NCCN prostate cancer guideline.PHASES Score (5-year aneurysm rupture risk)Estimates the 5-year rupture risk of an unruptured intracranial aneurysm from population, hypertension, age, size, prior SAH and site.ELAPSS Score (aneurysm growth risk)Estimates the 3/5-year growth risk of an unruptured intracranial aneurysm from prior SAH, location, age, population, size and shape.Carotid Stenosis (NASCET / ECST)Compute extracranial ICA stenosis from diameters (NASCET, optional ECST) with grade and management direction.Intracranial Stenosis (WASID)Compute intracranial arterial stenosis from diameters (WASID method) with grade and management direction (distinct from extracranial NASCET).Carotid Vulnerable-Plaque Feature AssessmentCheck carotid-plaque high-risk imaging features (IPH, large lipid core, thin/ruptured cap, ulceration, ultrasound hypoechogenicity) to assess vulnerability.Chinese Small-Aneurysm (≤ 5 mm) Rupture Risk (Morphologic)For ≤ 5 mm small aneurysms, assesses rupture risk by morphologic irregularity, aspect ratio (AR), size ratio (SR), and clinical factors, complementing PHASES.

Cervical cancer FIGO 2018 stagingFIGO 2018 stage for cervical cancer from local extent, nodes, adjacent organs, and distant metastases, with management direction.Ovarian / Tubal / Peritoneal Cancer FIGO 2014 StageDerive the FIGO 2014 stage from confinement, pelvic spread, retroperitoneal nodes, extrapelvic peritoneal disease and distant metastasis.GTN WHO/FIGO Prognostic ScoreSum of 8 prognostic factors for gestational trophoblastic neoplasia; ≤ 6 low risk (single-agent chemo), ≥ 7 high risk (combination chemo).Risk of Malignancy Index (RMI, Adnexal Mass)RMI = ultrasound score U × menopausal status M × CA-125; a cut-off of 200 separates benign from malignant and guides gynecologic-oncology referral.Sedlis Criteria (Adjuvant RT after Cervical Cancer Surgery)After radical surgery for early cervical cancer (nodes/margins/parametria negative), judge adjuvant pelvic radiation from LVSI, stromal invasion depth and tumour size.Endometrial Cancer FIGO 2023 Stage (with molecular)Derive the FIGO 2023 stage from histologic aggressiveness, anatomic extent and molecular subtype (POLEmut/MMRd/p53abn/NSMP).Vulvar Cancer FIGO 2021 StageDerive the FIGO 2021 vulvar cancer stage from tumour size/invasion depth, local spread, inguinofemoral nodes and fixation/distant disease.Abnormal Cervical Screening Management (ASCCP 2019)Give the ASCCP 2019 risk-based management direction and clinical action threshold from the current screening result (exact risk needs prior history).GTN FIGO Anatomic StageFIGO 2000 anatomic staging (I–IV) of gestational trophoblastic neoplasia, expressed together with the prognostic score (e.g. III:7).Endometrial Cancer Mayo Lymphadenectomy IndicationUse the Mayo criteria (histology, grade, myometrial invasion, tumour size) to judge whether an endometrioid adenocarcinoma can be spared lymphadenectomy.Cervical Cancer Querleu-Morrow Radical Hysterectomy TypeStandardise radical hysterectomy by lateral parametrial resection extent (A/B/C/D), with resection landmarks and indications.Ovarian Cancer Suidan Score (Suboptimal Cytoreduction Prediction)In advanced ovarian/tubal/peritoneal cancer, use pre-operative CT findings + CA-125 + clinical factors to predict suboptimal primary cytoreduction (residual > 1 cm) risk.Ovarian Cancer Fagotti Laparoscopic ScoreSeven diagnostic-laparoscopy findings (each 0/2) predict the likelihood of optimal cytoreduction in advanced ovarian cancer; PIV ≥ 8 favours neoadjuvant chemotherapy.Risk of Ovarian Malignancy Algorithm (ROMA Index)Combine HE4, CA-125 and menopausal status to compute ROMA% and triage an adnexal mass into high/low risk of epithelial ovarian cancer.Performance Status ECOG / KarnofskyECOG (0–5) and Karnofsky (0–100) performance-status correspondence, with the performance threshold for systemic therapy.

About the guideline decision tools
Each tool implements a guideline's decision logic (algorithm, thresholds, workflow) and names the source guideline and version. The algorithms themselves are not copyrighted, but guidelines are updated — conclusions must follow the latest version and be individualized to the whole patient. All results are for licensed clinicians and do not replace clinical judgement.
