Objective.: Colour Doppler ultrasonography (CDUS) is very important in general vascular diagnostic procedures. Its role in determining the extent of vasculopathy in Systemic Sclerosis (SSc) needs further investigation. The aim of this study was to compare the presence of altered arteries with nailfold capillaroscopy and clinical signs of ischaemia, that is, digital ulcers or pitting scars (DU/PS). A feasible CDUS protocol is provided. Methods.: Two thousand five hundred and twenty-eight arteries of the fingers, palms and wrists from 79 SSc patients (32 arteries per patient) were examined using CDUS...

Nowadays noninvasive vascular imaging has an important role in the diagnostic work-up of the large vessel vasculitides (LVV), most importantly giant cell arteritis (GCA) and Takayasu arteritis. Among the imaging modalities available, ultrasound (US) has several important advantages, including low costs, rapid and repetitive availability without exposure to radiation, and high spatial resolution for assessment of large and medium-sized arteries. Therefore, US can be regarded the first line imaging method in suspected LVV...

Introduction The placement of intramammary marker clips has proven to be helpful for tumor localization in patients undergoing neoadjuvant chemotherapy and breast-conserving surgery. The purpose of our study was to investigate the feasibility of using a clip marker system for breast cancer localization and its influence on the imaging assessment of treatment responses after neoadjuvant chemotherapy. Patients and Methods Between March and June 2015, a total of 25 patients (n = 25), with a suspicion of invasive breast cancer with diameters of at least 2 cm (cT2), underwent preoperative sonographically guided core needle biopsy using a single-use breast biopsy system (HistoCore™) and intramammary clip marking using a directly adapted clip system based on the established O-Twist Marker™, before their scheduled preoperative neoadjuvant chemotherapy...

Impingement syndrome of the ankle is a clinical diagnosis caused posttraumatically by overuse due to repetitive mechanical loading or the presence of predisposing anatomical variants. Ankle impingement syndrome is characterized by chronic pain and limited range of movement caused by mechanical compression of bony or soft tissues within the joint compartments. Ankle impingement syndrome is classified according to the various anatomical locations around the tibiotalar joint as anterior, anterolateral, anteromedial, posterior or posteromedial...

PURPOSE: We present the evaluation of the reproducibility of measurements performed using robotic ultrasound imaging in comparison with expert-operated sonography. Robotic imaging for interventional procedures may be a valuable contribution, but requires reproducibility for its acceptance in clinical routine. We study this by comparing repeated measurements based on robotic and expert-operated ultrasound imaging. METHODS: Robotic ultrasound acquisition is performed in three steps under user guidance: First, the patient is observed using a 3D camera on the robot end effector, and the user selects the region of interest...

PURPOSE: The presence of anterolateral ligament of the knee is still controversial, and some physicians prefer to call this structure anterolateral complex (ALC) to infer plural nature of structures involved. The purpose of this study was to describe the scanning techniques and to classify various sonographic appearances of the tibial-side ALC of the knee in subjects with anterior cruciate ligament (ACL) injury. It was hypothesized that sonographic abnormity of the ALC would be associated with ACL injury history...

Focused assessment with sonography in trauma (FAST) has been extensively utilized and studied in blunt and penetrating trauma for the past 3 decades. Prior to FAST, invasive procedures such as diagnostic peritoneal lavage and exploratory laparotomy were commonly utilized to diagnose intraabdominal injury. Today the FAST examination has evolved into a more comprehensive study of the abdomen, heart, chest, and inferior vena cava, and many variations in technique, protocols, and interpretation exist. Trauma management strategies such as laparotomy, laparoscopy, endoscopy, computed tomographic angiography, angiographic intervention, serial imaging, and clinical observation have also changed over the years...

A 40-year-old woman presented with severe vaginal bleeding. Initial workup with an abdominal sonography revealed endometrium for about 3 mm and free fluid in the abdomen. Hemodynamic instability with abdominal pain and free fluid in the abdomen prompted blood transfusion and laparotomy. There were about 1000 cc blood and clots in the abdomen at laparotomy. There was a longitudinal rupture from fundus up to cervix at the left side of the uterus. Tearing was in full thickness from serosa to endometrium. Scar of previous cesarean was transvers and not associated with this tearing...

Varicocele is characterized by an abnormal dilatation and retrograde blood flow in the spermatic veins. Varicocele is the leading correctable cause of male infertility. Although it is highly prevalent in infertile men, it is also observed in individuals with normal fertility. Determining which men are negatively affected by varicocele would enable clinicians to better select those men who will benefit from treatment. To assess the functional status of the testes in men with varicocele, color Doppler sonographic parameters were evaluated...

REVIEW
Johannes Gossner
Capsular contracture or capsular fibrosis is the most common complication following breast augmentation with implants. Sonography is usually the initial imaging test performed to examine a suspicious implant. In contrast to the large number of patients developing capsular fibrosis there is only sparse literature reporting about sonographic findings. In this letter after a brief review of normal sonographic findings after breast augmentation, established ultrasound findings suggestive of capsular fibrosis (deformity, increased number of radial folds and thickening of the fibrous capsule) are discussed...

Vagal paragangliomas are rare benign tumors accounting for only 3% of head and neck paragangliomas and arise from vagal ganglions, predominately the nodose ganglion in the carotid sheath. Imaging plays an important role in their diagnosis, differentiation from more common lesions presenting in the carotid space, and management. MRI is the method of choice for investigation when paragangliomas are clinically suspected. The typical salt-and-pepper appearance in T1-weighted images is well known but not specific to paragangliomas...
