“…In recent publications, however, it has been shown that these complications can be minimized with the use of color Doppler sonographic guidance. [3][4][5] In conclusion, sonographically guided TTNA is useful in the diagnosis of peripheral pulmonary lesions of the thorax. It does not involve exposure to radiation; it is inexpensive and quick to perform; and it is associated with a low complication rate.…”

“…2 Almost all studies of sonographically guided TTNA in the literature have been performed with conventional B-mode sonography, but a few studies have been reported in which color Doppler sonography was used. 3,4,[7][8][9] All of these studies showed that color Doppler sonographically guided TTNA was a safe diagnostic method for malignant lung tumors, especially those in peripheral locations.…”

“…Because of advantages such as the better differentiation of vascular structures and clearer visualization of the needle shaft or tip within the lesion, the use of color Doppler sonographically guided TTNA is increasing. [3][4][5] In this study, we aimed to investigate the diagnostic value of color Doppler sonographically guided TTNA in the examination of thoracic tumors and to compare the ability of gray scale and color Doppler sonographic images to visualize vascular structures and the needle tip during the procedure.…”

Objective. This study investigated the diagnostic value of color Doppler sonographically guided transthoracic needle aspiration in lung and mediastinal masses. Methods. B-mode and color Doppler sonographic images were obtained in 48 patients with mediastinal or peripheral pulmonary tumors. Color Doppler sonography was used to show the vascular structures before the transthoracic needle aspiration procedure. It was also used to locate the needle tip during the procedure by showing the twinkling sign. This maneuver was performed with motion of the inner stylet. Pathologic and microbiological examination of the aspirates was made. Results. Vascular structures were detected in 37 cases on color Doppler images and in 10 cases on B-mode images. Similarly, the needle tip was observed in 39 cases on color Doppler images but in only 9 cases on B-mode images. No complications were observed except partial pneumothorax in 2 cases. The method had sensitivity of 90.0%, specificity of 87.5%, a positive predictive value of 97.2%, a negative predictive value of 63.6%, and diagnostic accuracy of 89.6%. Conclusions. Color Doppler sonographically guided transthoracic needle aspiration is a safe diagnostic method in malignant lung tumors, especially peripheral tumors, because of its ability to differentiate vascular structures within a tumor before the transthoracic needle aspiration procedure. It provides additional information about the location of the needle tip.

“…We will accept to buy these costly needles once evidence is shown that this does not. Color Doppler help has been described [3], as well as the cabled transmission of an electric source at the end of the probe [4,5]. Some inject small quantities of air in order to locate the end of the needle.…”
