Role of color Doppler imaging in interventional sonography

Role of color Doppler imaging in interventional sonography nterventional ultrasound procedures have increased as a result of the advent of biopsy guides, specialized transducers, and improved image quality. Color Doppler sonography (CDUS) enhances interventional capability because it enables visualization of vessels that cannot be identified on gray-scale imaging. With CDUS, one can avoid puncture of critical blood vessels in the path to a lesion during needle biopsy, assess the pattern of lesion perfusion to identify occult neovascularity or discriminate perfused from avascular regions for preferential sampling, and monitor vascular intervention in a real-time fashion. This pictorial essay provides illustrative cases to demonstrate the use of CDUS for these purposes. AVOIDING VESSEL PUNCTURE Avoiding puncture of vessels during needle biopsy is important to diminish bleeding risk. This is particularly critical in the brain, where bleeding is difficult to control without damage to adjacent tissue. Cerebral blood vessels may be invisible on gray-scale imaging yet may have significant bleeding potential. Cerebral bleeding may complicate biopsy and/or resection, and postoperative cerebral bleeding or hematoma may have significant, irreversible sequelae because of the mass effect in a fixed space. For these reasons, CDUS is especially useful to minimize cerebrovascular disruption and should be used routinely in cerebral tumor mapping (Figure http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Clinical Ultrasound Wiley

Abstract

nterventional ultrasound procedures have increased as a result of the advent of biopsy guides, specialized transducers, and improved image quality. Color Doppler sonography (CDUS) enhances interventional capability because it enables visualization of vessels that cannot be identified on gray-scale imaging. With CDUS, one can avoid puncture of critical blood vessels in the path to a lesion during needle biopsy, assess the pattern of lesion perfusion to identify occult neovascularity or discriminate perfused from avascular regions for preferential sampling, and monitor vascular intervention in a real-time fashion. This pictorial essay provides illustrative cases to demonstrate the use of CDUS for these purposes. AVOIDING VESSEL PUNCTURE Avoiding puncture of vessels during needle biopsy is important to diminish bleeding risk. This is particularly critical in the brain, where bleeding is difficult to control without damage to adjacent tissue. Cerebral blood vessels may be invisible on gray-scale imaging yet may have significant bleeding potential. Cerebral bleeding may complicate biopsy and/or resection, and postoperative cerebral bleeding or hematoma may have significant, irreversible sequelae because of the mass effect in a fixed space. For these reasons, CDUS is especially useful to minimize cerebrovascular disruption and should be used routinely in cerebral tumor mapping (Figure
