MEDS12003 Lecture 1: SS week 1 notes
WEEK 1 Intro to scanning
Patient positions
Scanning planes
Probe orientation
When patient is supine:
• Probe is in long, probe to patient superior
• Probe is in transverse, probe to patient right
Views
Transducer motions
• Sliding
• Compression
• Rocking (heeling/toeing)
• Rotation – “rotate to elongate”
• Tilting/angling
• Fanning – “fan to find”
Describing:
• Location & RELATIVE location.. Anterior to
• Size…. Need to measure and calculated volume….. (L x W x H) x 0.529 = __ mL
• Shape - round, oval, oblong, irregular
• Number – how many
• Echogenicity – how bright is it?
• Echotexture – internal composition
• Contour – border description
• Vascularity – how much blood flow
• Artifacts seen – Post Shadow, Post.Enhance, Comet Tail etc.
• Complications associated
Focal vs diffuse
Focal or diffuse? → size of whole gland, borders, echogenecity – holistic look, big picture
If focal: Pass a large van (pass a L V)
P – position
o Intraglandular vs extraglandular/intratesticular vs extratesticular
A – appearance
o Borders/margins – sharp, defined, blurred, irregular, halo effect and
echogenecity of such
o Internal contents – echogenecity
Document Summary
When patient is supine: probe is in long, probe to patient superior, probe is in transverse, probe to patient right. Transducer motions: sliding, compression, rocking (heeling/toeing, rotation rotate to elongate , tilting/angling, fanning fan to find . Describing: location & relative location anterior to, size . Size of whole gland, borders, echogenecity holistic look, big picture. If focal: pass a large van (pass a l v) A appearance: borders/margins sharp, defined, blurred, irregular, halo effect and echogenecity of such. S size: larger/smaller than normal, does it have a space occupying effect, singular or multiple. A artefact: artefact type (if any present) L (large) lymph node involvement: lymph node involvement (if present) V (van) vascular: vascularity no change/increased/decreased. Understanding the characteristics of each link provides the health care giver with methods to support vulnerable patients and to prevent the spread of infection. An awareness of this cycle also provides knowledge of methods of self-protection so the chain can be broken.
