Ultrasonographic Patterns and Pathological Correlation in the Diagnosis of Subcutaneous Nodules

"The ultrasonographic characteristics of the subcutaneous nodules were evaluated using an ultrasound machine (Venue Go™, wide-band linear array ultrasound probe (hockey stick shape), frequency range between 6.7 MHz and 18.0 MHz, from GE HealthCare Illinois, United States).~The procedure for capturing images at the location of the lesion of interest is as follows:~* Brightness mode (B-mode): Record at least 4 images using a depth of 2 cm.~* Color Doppler mode: Record images along the vertical axis (1 image) and along the horizontal axis (1 image). The two axes mentioned above must be perpendicular to each other.~* Video recording: Capture at least 10 seconds of video in both Brightness mode and Color Doppler mode."
