Groin Lymph Nodes Ultrasound Image interpretation . normal size of head and neck lymph nodes is generally less than 0.8 cm. diagnostic yield of biopsy will increase with lymph node size, and specificity might decrease if biopsy is performed of nodes <1 cm in size. as described above, normal lymph nodes are oval shaped and have a homogeneous echotexture. Features that favor reactive infective nodes over malignancy include: nodal matting; surrounding soft tissue edema; doppler features. doppler examination is particularly useful in helping distinguish reactive nodes from metastatic disease 1. reactive nodes (including those in tuberculous lymphadenitis) demonstrate: prominent hilar vascularity. Ultrasonography is the use of sound waves to generate medical diagnostic images. the portability, cost effectiveness, and non invasive nature of ultrasound have contributed to its widespread use over recent decades.[1] vascular ultrasound is a generalized term that includes venous duplex and doppler sonographic assessment of myriad arterial and venous pathology, most commonly including. The first group of mistakes includes inappropriate interpretation of images of anatomical structures, while the latter group includes, among other things, similar ultrasound images of different pathologies. for instance, a lymph node, whether normal or abnormal, may be mimicked by anatomical structures, such as a partially visible, compressed vein.
