Handbook of Diagnostic Sonography 2026 is built for RDMS candidates and clinical learners who need to connect ultrasound physics, cross-sectional anatomy, pathology recognition, Doppler interpretation, and protocol completion into one usable scanning method. The book moves from SPI foundations and image optimization into abdomen, OB/GYN, vascular, cardiac, breast, thyroid, scrotal, neonatal brain, pediatric, and superficial-structure sonography, always tying the image to the structure and the structure to the clinical question. The Scan-to-Structure Mapping System gives readers a repeatable framework for moving from probe position to anatomic target, from normal sonographic appearance to pathology pattern, and from Doppler or measurement anchor to complete documentation. What This Book Helps You Do • Integrate SPI principles with clinical scanning — use frequency, gain, focus, Doppler scale, artifacts, and acoustic windows to improve diagnostic confidence. • Navigate abdominal sonography by structure — connect liver, biliary, pancreatic, renal, splenic, vascular, trauma, and postoperative findings to protocol-based imaging. • Build OB/GYN reasoning by timing and anatomy — localize pelvic structures, follow pregnancy-stage expectations, document fetal and maternal findings, and state limitations clearly. • Interpret vascular studies through hemodynamics — connect compression, color flow, spectral Doppler, waveform morphology, physiologic testing, and stenosis logic. • Recognize pathology across systems — separate cystic, solid, complex, calcified, vascular, inflammatory, ischemic, and obstructive patterns before naming disease. • Complete specialty protocols — document required views for echo, breast, thyroid, s*****m, neonatal brain, pediatric abdomen, pylorus, hip, spine, and soft tissue. • Strengthen registry-oriented practice — organize anatomy, protocols, Doppler, measurements, artifacts, limitations, and urgent communication without question-based review formats. Use it to build the scanning habits that support RDMS preparation and safer diagnostic sonography at the bedside, lab, and imaging suite.
