Imaging Studies II: Ultrasonography

113
IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Ultrasonography

7.0K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Area of Science:

  • Medical Education
  • Surgical Training
  • Diagnostic Imaging

Background:

  • Thyroid ultrasound is crucial for surgical planning but residents lack formal training.
  • Developing standardized training is essential for improving surgical outcomes.

Purpose of the Study:

  • To create a novel thyroid ultrasound proficiency metric.
  • To establish a standardized assessment tool for surgical residents.

Main Methods:

  • A Delphi panel of experienced faculty developed the Ultrasound Proficiency Scale (UPS-Thyroid).
  • Items were iteratively refined and voted on until consensus was reached.
  • The scale was pilot tested on surgery residents, with learning curves assessed.

Main Results:

  • The UPS-Thyroid includes 14 items across 5 categories (Positioning, Technique, Image Capture, Measurement, Interpretation).
  • A proficiency threshold was set at 36 points.
  • Learning curve analysis indicated proficiency was achievable within 4-7 repetitions.

Conclusions:

  • A multidisciplinary Delphi approach successfully created the UPS-Thyroid.
  • Surgery residents can achieve basic thyroid ultrasound proficiency within 10 repetitions.
