Abdominal Ultrasound
Comprehensive abdominal ultrasound — liver, gallbladder / biliary tree, pancreas, kidneys, spleen, abdominal aorta, and bladder. First-line for right-upper-quadrant pain (gallstones, cholecystitis), hepatic lesion characterization, renal evaluation, AAA screening, and acute appendicitis in children. No ionizing radiation; portable, real-time, and operator-dependent.
Clinical pathway
NPO 6+ hours for gallbladder evaluation; full bladder for pelvic windows. Curvilinear 2–5 MHz probe is the workhorse; linear high-frequency probes for superficial structures (appendix, hernia); color and spectral Doppler for portal venous, hepatic arterial, and renal vascular assessment; contrast-enhanced ultrasound (CEUS with Lumason or Definity) for selected lesion characterization where MRI / CT is contraindicated or equivocal.
Typical systems
- GE LOGIQ E9
- GE LOGIQ E10
- Philips EPIQ Elite
- Philips iU22 — large refurb base
- Siemens ACUSON Sequoia
Room + procedure characteristics
- Scan time: 20–40 min.
- Dose: none (non-ionizing); thermal and mechanical indices monitored on-screen.
- Team: sonographer acquires, radiologist interprets and may re-scan equivocal findings.
Equipment considerations that bite
- Probe portfolio is the system. A premium cart without the right curvilinear and linear probes is a gutted asset on the refurb market. See C5-1 / C8-5 / L12-5 examples on the iU22 line.
- Penetration on technically difficult patients — body habitus is the limit, not depth setting. Premium curvilinear probes (PureWave on Philips, equivalents on GE / Siemens) earn their refurb premium on habitus-challenged patients.
- Compound imaging + speckle reduction — SieClear (Siemens), SonoCT (Philips), CrossXBeam + SRI (GE). Readability gains live here.
- Ergonomics — height-adjustable control panel, monitor articulation, scan-arm reach. Repetitive-motion injury rates in sonography are among the highest in healthcare; ergonomics is a clinical-program retention issue, not a comfort feature.
Operational reality
- Sonographer-driven exam. The acquisition is the interpretive event; a tired or undertrained sonographer produces a non-diagnostic study even on a top-tier cart.
- Throughput is sonographer-limited, not equipment-limited, on routine abdominal volume.
- Refurb economics track probe inventory and software-license tier far more than chassis age — a clean cart with no decent probes is barely a starter machine.
