Practice Head and Neck Ultrasound Guided Biopsies
A transparent gelatin mold (ultrasound phantom) is extremely encouraged as a coaching tool though understanding how to execute ultrasound guided biopsies. It assists comprehend the three dimensional ultrasound image and hand-eye coordination necessary for this sonography process.

How To Make Your Personal Head and Neck Ultrasound Guided Biopsy Phantom in 9 Measures
- 1 container (no deeper than two inches)*
- eight packets of Knox gelatin
- five olives filled with pimento
- four plastic forks
- two disposable cups
- Hot water
- Plastic wrap
- Pour two gelatin packets into container Spread the content material more than the bottom.
- Gradually add hot water to gelatin Dissolve gelatin though stirring with a fork Make confident you kind as handful of bubbles as achievable.
- Right after the gelatin is dissolved fill container halfway To speed up the procedure use cool water Add an ice cube or two for even speedier final results Spot in fridge and let solidify.
- Spot olives in the center of the solidified layer.
- Spot one particular packet of Knox gelatin in a clean cup Dissolve gelatin with hot water and a fork Add some cold water and one particular ice cube to cool mixture Use no far more than eight oz. of fluid Make confident there are no bubbles in this layer that will interfere and develop artifacts in the Ultrasound image.
- Spot semi coagulated mixture (area temperature) straight more than olives Spot in fridge to additional harden.
- Make far more gelatin following Step 5 Use four packets generating one particular at a time The batch requirements to be sufficient to almost fill the container the container Make confident the liquid will not melt the reduce layer.
- Make one particular far more packet of gelatin Add though container rests in fridge to avert overflowing.
- Place a handful of drops of water on the hardened surface Lightly spread water more than surface Spot plastic wrap more than mold and smooth out wrinkles Plastic protects the surface somewhat from cracking.

How To Use The Head and Neck Ultrasound Guided Biopsy Phantom You Created
Ultrasound probe placement should really be in the non-dominant hand.
A light touch is necessary throughout ultrasound guided biopsies – the gelatin mold facilitates this considering the fact that it will crack if also a great deal stress is applied.
Move the ultrasound probe/transducer more than the phantom and comprehend the placement of the olives beneath the probe and on the screen.
Determine exactly where the needle should really be placed beneath the probe. Watch the best of the screen to see exactly where the needle seems in the screen. Note if the needle is traveling towards the “nodule”.
Study to appreciate the truth that: it is not achievable to stick to the needle if the transducer is not moved when applying the “perpendicular” biopsy strategy the needle will seem as a smaller sized than anticipated object on the screen quite smaller controlled movements of the probe are finest.
Tracks developed by the needle placement will stay visible in the gelatin. Move the container about to get one more spot to retry a biopsy.
