Scanning tips

Free tip sheets for the scan room: the habits that protect your body, clean up your images, and keep your exams complete, whether you are in clinicals or years into the job.

Ergonomics: scan without wrecking your body

Most sonographers deal with work related pain at some point in their career. Small setup habits, repeated every exam, are what keep you scanning for the long haul.

  • Bring the patient to you. Pull them to the edge of the bed nearest you and raise the bed so you are not reaching or hunching.
  • Keep your scanning arm low. Aim for shoulder abduction under about 30 degrees, elbow close to your side, wrist in a neutral position.
  • Support the cable. Drape it over your arm or shoulder so its weight is not hanging off your wrist all exam long.
  • Move the machine, not your spine. Roll the scanner and adjust the monitor instead of twisting to see the screen.
  • Lighten your grip. Use the minimum pressure that keeps contact, and let gel and gravity do some of the work.
  • Take micro breaks. Drop your arm and shake out your hand between patients, and stretch your neck, shoulders, and forearms through the day.

Doppler angle: live by the 60 degree rule

Velocity math only behaves at shallow angles. Past 60 degrees the cosine curve turns steep, and a tiny angle error becomes a huge velocity error.

  • Aim for a 45 to 60 degree angle and follow your lab's protocol. Many labs aim for a 45 to 60 degree window for velocities they plan to report. Follow your lab's protocol, and get as close to parallel with flow as the anatomy allows.
  • Steer the color box and heel toe the probe to improve your angle before you ever touch the angle correct.
  • Line the cursor up with the vessel walls in straight segments. Flow follows the walls, so your cursor should too.
  • Never measure at 90 degrees. The Doppler shift there is zero, no matter how fast the blood is moving.
  • Stay consistent on follow ups. Serial exams only compare fairly when the angle and sample site match the last study.
  • Follow your lab's protocol. Some labs prefer a tighter window, like 45 to 60 degrees, so check your lab's protocol and scan to that standard.

Harmonics and your image rescue kit

When an image looks rough, work a short checklist before you blame the patient. These are the first knobs to reach for.

  • Turn on tissue harmonics. Harmonic imaging cleans up near field clutter and reverberation, and often sharpens cysts and fluid filled structures.
  • Drop the frequency for depth. Lower frequency penetrates farther on larger patients. Coded excitation, if your machine has it, buys back signal at depth too.
  • Put the focal zone at or just below the structure you care about. That is where lateral resolution is at its best.
  • Fix brightness with TGC first, then overall gain. Brightness should be even from top to bottom of the image.
  • Change the window. Roll the patient into a decubitus position, try a deeper breath hold, or scan from a different approach before you give up on an organ.

A scanning protocol that catches everything

A repeatable routine is your safety net. When every exam follows the same skeleton, the day you are tired or rushed is the day it saves you.

  • Survey first, stills second. Sweep through the whole organ in real time before you start saving images, so nothing surprises you later.
  • Image in two planes. Every structure and every finding gets a long and a transverse view. One plane can lie to you.
  • Measure at the standard landmarks your lab protocol calls for, the same way every time, so numbers compare across exams.
  • Compare sides. Kidneys, ovaries, thyroid lobes, and limbs come in pairs for a reason. The normal side is your built in control.
  • Document pathology three ways: in two planes, with and without measurements, and with a cine clip if it moves or flows.
  • End with a sweep of the gutters and fluid spaces. Free fluid loves to hide in the places a focused exam skips.

Annotation and labeling: images that speak for themselves

Your images may be read hours later by someone who was not in the room. Good labels mean they never have to guess what they are looking at.

  • Label every image: organ, side (right or left), and plane (long or transverse) at minimum.
  • Note the approach and position when they are nonstandard, like decubitus or upright.
  • Annotate findings in plain words: cyst, mass, stone, plus where it sits, so the finding on the worksheet matches the image.
  • Follow your lab orientation protocol the same way on every exam. Consistency is what makes labels trustworthy.
  • Mark measurements on the image as you take them, not from memory at the end of the exam.

Artifact or real? A field guide

Artifacts are not the enemy. Read correctly, they are diagnostic clues. Read wrong, they become findings that were never there.

  • Posterior enhancement behind a fluid filled structure supports that it really is fluid. Cysts and the bladder light up the tissue behind them.
  • Clean shadowing points to stone or calcium. Dirty shadowing with reverberation points to gas. Know which one you are looking at.
  • Mirror image duplicates a structure across a strong reflector like the diaphragm. Change your angle and the twin disappears.
  • Edge shadowing at the curved side of a round structure is refraction, not a finding. Expect it at cyst and gallbladder walls.
  • Side lobe clutter can drop faint echoes inside cysts and the bladder. Harmonic imaging and a different window usually clear it.
  • The golden rule: real structures persist in two planes and from a second window. Artifacts shift, shrink, or vanish when you move.
