“…The descriptive sign of irregularly branching vessels with chaotic flow appears to be useful in the diagnosis of malignant breast tumours, as all such cases were proved to be malignant. This observation is similar to that of Raza et al 5 Other parameters of blood flow like average number of vessels per square centimeter and average density of colour pixels, used by early workers 3,13 were not utilized in the present study, as they are semiquantitative in nature. The average peak systolic velocity in the malignant tumours is more than that in benign ones, in the present study; however the distribution of the velocities is over a very wide range within benign or malignant tumours, resulting in wide degree of overlap on comparison of the two; this precludes the possibility of using PSV in differentiating malignanttumours from the benigno9 ones.…”

“…The color gain was increased until background noise appeared and then reduced until the noise was suppressed, thus ensuring maximum sensitivity. 6,7 When consistent Doppler signals were obtained, the color map was used to guide placement of the pulsed Doppler gate, and tracings of the arterial signal were recorded using a sample volume of 1 mm. The vascular resistance was evaluated at random sites within 3 vessels that consistently showed 3 consecutive Doppler spectral waveforms.…”

Objective. To investigate the difference in the nodal hilus evaluated by gray scale and power Doppler sonography. Methods. One hundred ninety-two patients with proven cervical lymphadenopathy were included in the study (metastases, n = 118; tuberculosis, n = 56; and lymphoma, n = 18). Lymph nodes were evaluated by gray scale sonography for the echogenic hilus and power Doppler sonography for hilar vascularity. Results. Hilar vascularity was found even though the lymph node did not show an echogenic hilus on gray scale sonography (metastases, 59%; tuberculosis, 66%; and lymphoma, 91%). Conclusions. Sonologists should be aware that gray scale and Doppler sonography show different aspects of the hilus, and the absence of the hilus on gray scale sonography does not necessarily imply an associated absence of hilar vascularity. Key words: gray scale sonography; power Doppler sonography; hilus; cervical nodes. he role of sonography in the evaluation of neck nodes is well established. Previously, sonography of lymph nodes involved only gray scale sonography, and evaluation of the nodal hilar architecture was an essential part of the examination. The absence of a hilus was usually considered an abnormality.1,2 However, to our knowledge, the sonographic literature has not addressed whether the absence of an echogenic hilus on gray scale sonography implies the absence of hilar vasculature. With power Doppler sonography (PDS), it is now possible to evaluate intranodal vasculature.In our experience, often in abnormal nodes the echogenic hilar architecture is absent on gray scale imaging (Fig. 1), but the hilar vessels are clearly shown on PDS (Fig. 2). Because this has not been emphasized in the literature, often sonologists have presumed that the absence of the echogenic hilus on gray scale sonography also implies the absence of hilar vasculature. We were therefore interested in documenting the appearance of hilar vessels so that sonologists would be aware of the differences in nodal hilar evaluation by gray scale sonography and PDS.

Amaç: Bu çalışmada, solid meme kitlelerinde, malign lezyonların benign kitlelerden ayırdedilme-sinde B-mod, renkli ve power dopler ultrasonografinin (US) önemi araştırılmıştır. Hastalar ve Yöntem:Biyopsi sonucu olan 83 solid meme kitlesi (25 malign; 58 benign) 7,5-12 MHz lineer problar kullanılarak B-mod, renkli ve power dopler US ile değerlendirildi. Kitlelerdeki dopler vasküler akım sinyallerinin lokalizasyonu, dağılımı ve şekli incelendi. Bu akımlar santral, periferal ve santral+ periferal olarak gruplandırıldı. B-mod US ile, lezyonların Transvers/ sagittal (T/ S) oranları; ekojeniteleri; akustik şiddetlenme/ zayıflamaları değerlendirildi. Sonuçlar:Renkli ve power dopler US'de artmış vaskülarite, malign potansiyelin güçlü bir belirleyicisidir. p değeri anlamlı çıkmamakla birlikte, periferal+ santral vaskülaritenin saptanması; rezistivite indeksinin 0,75'den (duyarlılık: %85, özgüllük: %92); pulsatilite indeksinin 1,6'dan (duyarlılık: %95, özgüllük: %68) büyük olması lezyonun malign çıkma ihtimalini güçlendirmektedir. Ayrıca, B-mod US ile saptanan T/ S oranındaki artışın malignite riski ile ilişkili olduğu görülmüştür. Patient and Methods:Eighty-three biopsy-proven solid breast masses (25 malignant and 58 benign) were evaluated with B-mode, color and/ or power Doppler ultrasonography (US) using a 7,5-12 MHz linear-array transducer. We analyzed the location, shape, and penetration of the Doppler vascular signals in the breast masses. The location of the vascular signals was categorized as central, peripheral or both. With B-Mode US, Transverse/ sagittal (T/ S) ratios of lesions; echogenicity; acoustic enhancement/ decrease were also evaluated.Results: Increased vascularity both in color and power doppler US, is a strong indicator for malignancy. Although the p value is insignificant, doppler features suggestive of malignant lesions were the presence of both peripheral and central vascularity; resistivity index greater than 0,75 (sensitivity: 85%, specificity: 92%) and pulsatility index greater than 1,6 (sensitivity: 95%, specificity: 68%). Also, increase in T/ S ratio measured by B-mode US was suggestive of malignancy. Conclusions:Color and Power Doppler imaging are both valuable adjunct to conventional Bmode sonography in differentiating between malignant and benign breast lesions.
