We aim to investigate the significance of microvascular ultrasonography in breast ductal lesions for distinguishing benign from malignant lesions. Sixty-two ductal lesions were evaluated with gray-scale and three Doppler techniques before biopsy, Superb Microvascular Imaging (SMI), color Doppler (CDI), and power Doppler imaging (PDI). We evaluated number, distribution, and morphology of vessels. The area under the ROC curve of combined use of Doppler imaging was greater than that of gray-scale only and SMI had higher value than CDI and PDI (p < 0...

Cesarean scar pregnancy (CSP) is a rare kind of ectopic pregnancy implanted in the previous cesarean scar and has an increasing incidence over the past 30 years. As the suspicion is low, the diagnosis may be delayed or misinterpreted in ultrasound, leading to treatment strategies that might end up in uterine rupture or hysterectomy. The objective here is to review the ultrasound findings in CSP with varied presentations. Transabdominal and transvaginal sonography combined with color Doppler is a reliable tool for the diagnosis of CSP...

As a continuation of parts 1 1 and 2 2, this article discusses artifacts as caused by insufficient temporal resolution, artifacts in color and spectral Doppler sonography, and information regarding artifacts in sonography with contrast agents. There are artifacts that occur in B-mode sonography as well as in Doppler imaging methods and sonography with contrast agents, such as slice thickness artifacts and bow artifacts, shadows, mirroring, and artifacts due to refraction that appear, for example, as double images, because they are based on the same formation mechanisms...

Ectopic intrathoracic liver tissue is extremely rare. Studies are mainly limited to case reports. In the vast majority of reported cases, a diagnosis of intrathoracic liver tissue was made either after a thoracic surgery or during a postmortem examination. However, once included in differential diagnosis, surgical intervention or biopsy procedures may be avoided with optimal diagnostic approach. In the present study, we conducted a literature review and proposed a new classification method for accessory liver within the thoracic cavity...

The Jones criteria of 2 major criteria or 1 major plus 2 minor criteria that have been classically used to establish the diagnosis have been significantly modified in 2015 by the American Heart Association. The criteria now include the utilization of echocardiography and Doppler color flow mapping as diagnostic tools for carditis, along with defining criteria in relation to overall population risk, delineating low- versus moderate-high risk populations. Monoarthritis and polyarthralgia are now major criteria for moderate- to high-risk groups...

Dorsal Vein thrombosis, also known as Mondor's disease of the penis, is a superficial thrombophlebitis first described in the literature by Falco in 1955. Mondor's disease refers to a superficial thrombophlebitis of any locale. Diagnosis can be made clinically with palpation of a mobile, cord-like thickening on dorsum of penis without associated evidence of inflammation, infection, or dermatologic changes. Bedside ultrasonography with color Doppler can aid in the diagnosis of penile thrombophlebitis by revealing a noncompressible superficial vessel with normal surrounding flow...
