“…In malignant lymph nodes, this "color hilum" is lost or displaced while multiple vessels penetrate the nodal capsule and enter the lymph node, distributing anarchically. 1,16,19,29 As also suggested by other authors, 2 we find Doppler sonography particularly helpful in some indeterminate circumstances, improving the operator's confidence in suspecting malignancy. When a lymph node shows diffuse thickening of the cortex (ie, a lower than usual size of the echoic hilum), detecting hilar vascularization decreases our suspicion, whereas an abnormal vessel distribution prompts further investigation.…”

“…We do not inject sonographic contrast media to assess the nodal status of patients with melanoma. Some authors 2,19 have used these intravenous agents to increase the intranodal vascular signals in these patients, but we believe that the Doppler mode sensitivity of current scanners is sufficient, and its further intensification would not add relevant information (but would increase costs). There is some preliminary experience 20 on the use of contrast media to enhance gray scale images, showing the different perfusion behaviors of reactive and of metastatic lymph nodes.…”

Objective. Sonography is being used with increasing frequency in the assessment of locoregional tumor spread in patients with melanoma. Nevertheless, to maximize its practical impact, sonography should be performed with state-of-the-art equipment, by specifically trained operators, and using a careful exploration technique and well-defined diagnostic criteria. In this "how I do it"-type article, we illustrate our practical approach to sonography of cutaneous melanoma. Methods. We first illustrate the basic and advanced technical requirements; then we describe our exploration methods and our image interpretation approach; and finally, we report on our use of sonography as a guidance tool for interventional procedures. Special emphasis is given to methodological and interpretative clues, tricks, and pitfalls. Results. Sonography can be used in the initial staging of patients with melanoma, particularly in the screening of patients scheduled for a sentinel lymph node biopsy procedure. Additionally, sonography can be used during patient follow-up to detect locoregional recurrence earlier than palpation. Conclusions. Sonography plays a growing role in the assessment of the superficial spread of melanoma. Nevertheless, state-of-the-art equipment and careful exploration by trained operators are necessary.

“…Moreover, it is not easy to perform a dynamic study with MRI as the patients are usually not able to cooperate properly 3 . Ultrasound scanning has recently become an important diagnostic tool in dermatology because it is easy to use, completely safe and it provides important diagnostic information 9 . We believe that dermatologists should be familiar with anterior tibialis muscle herniation so that they can arrive at a proper diagnosis and make a surgical referral when they encounter positional subcutaneous nodules in the lower legs.…”

The term muscle herniation represents focal muscular protrusions through an acquired or congenital fascial defect. The anterior tibialis muscle is the most common site of herniation. Dynamic ultrasonography has become an important tool in dermatology for diagnosing suspected muscle herniation because it is a non-invasive, highly accurate, readily available and cost-effective imaging technique. We present here the case of a 21-year-old male Korean soldier who underwent dynamic ultrasonography to confirm the diagnosis of anterior tibialis muscle herniation.

“…Owing to its increased sensitivity to flow, power Doppler sonography is valuable in low-flow states and when optimal Doppler angles can not be obtained. Longer segments of vessels and more individual vessels can be visualized with power Doppler US than with conventional color Doppler sonography [1,2,9]. According to the vascular pattern detected on PDUS, the lesions were classified as having peripheral, central, or mixed-type vascularity, similar to a categorization reported for breast tumors [10].…”

“…PDUS has recently gained attention as an additional color flow imaging technique that overcomes some of the limitations of CDUS which include angle dependence and difficulty in separating background noise from true flow in slow-flow states [9]. Owing to its increased sensitivity to flow, power Doppler sonography is valuable in low-flow states and when optimal Doppler angles can not be obtained.…”

Anahtar KelimelerDeri Tümörleri; Gri Skala Ultrasonografi; Power Doppler Ultrasonografi; Renkli Doppler Ultrasonografi Abstract Aim: The aim of this study was to prospectively evaluate the usefulness of color Doppler ultrasonography, power Doppler ultrasonography, and gray scale ultrasonography in differentiating benign and malignant skin lesions. Material and Method: Patients were histopathologically divided into two groups as benign and malignant skin tumors. The dimensions of the lesion, the contour characteristics, existence of pagoda echo, levels of invasion, the internal echogenicities and vascular patterns were investigated. We analysed velocity waveforms and determinated peak systolic velocity, end-diastolic velocity, resistive index, and pulsatility index. Results: Eighty patients (35 female, 45 male) with populo-nodular lesions on the surface of the cutaneous and subcutaneous tissues were prospectively enrolled in this study. A significant difference was noted between malign and benign skin lesion groups as for color and power Doppler ultrasonographic findings such as blood flow analysis and as for the gray scale ultrasonographic findings such as irregular contour, pagoda echo and hypoechoic echogenicity. Blood flow was observed in 33 patients. The existence of the flow was mostly observed in 92.2% of the malign skin lesions and in 33.3% of the benign lesions. The analysis of peak systolic velocity, end-diastolic velocity, resistive index, and pulsatility index between the study groups did not reveal a significant difference (p>0.005). Discussion: Doppler ultrasound is a non-invasive and powerful technique for the differentiation of benign and malignant skin lesions.
