Diagnostic Radiology & Cross-Sectional Imaging Hub
Plain radiography quality checks (R-I-P-E), ABCDEFGHI systematic review, and emergency non-contrast CT brain.
Chest Radiograph (CXR): Systematic Interpretation
Rotation, inspiration (9-10 posterior ribs), penetration, and AP vs PA magnification. ABCDEFGHI framework, Felson's silhouette sign, air bronchograms, deep sulcus sign, Kerley B lines, and 5 hidden review zones.
Non-Contrast Computed Tomography (NCCT) Brain
Hounsfield unit attenuation scale, acute hemorrhage densities (+60 to +90 HU), Epidural vs Subdural hemorrhage suture rules, early ischemic stroke signs (loss of insular ribbon, ASPECTS score), and midline shift.
Interactive Imaging Workbench
Score a 10-region ASPECTS map on NCCT for anterior-circulation stroke and interpret attenuation with a Hounsfield-unit tissue/acute-blood helper.
NCCT ASPECTS Scorer (Anterior Circulation)
10/10ASPECTS 10 — no early ischemic change detected on non-contrast CT.
Hounsfield Unit Interpreter
Fresh clot. A mixed/hypodense core suggests subacute-chronic blood.
Teaching aid for attenuation interpretation — always correlate with window settings and clinical context.
