The aim of this study was to assess a possible association between breast malignancy and ipsilateral higher vascularity on gadolinium-enhanced MR angiography. One hundred six patients were examined by dynamic gadolinium-enhanced 3D MR imaging. Magnetic resonance angiographic views were generated by image subtraction and maximum intensity projection. The(More)
BACKGROUND Conventional ultrasound parameters such as the resistance index (RI) are only of limited use in the diagnosis of early allograft dysfunction. We, therefore, performed a prospective study to compare the value of ultrasound contrast media (USCM) with conventional US in the diagnosis of early allograft dysfunction. METHODS A total of 48(More)
The parotid gland is rarely affected by sarcoidosis (6% of all cases). If there is initial parotitis, and other major symptoms include fever, uveitis, or facial paralysis, the condition is referred to as Heerfordt's syndrome. The case presented here describes the diagnostic work-up and differentiation of swelling of the parotid gland by employing(More)
PURPOSE To describe an apparently unreported endovascular means of treating a vertebral arteriovenous fistula (AVF) using a small-caliber stent-graft to permanently reconstruct the involved vessels. CASE REPORT A 13-year-old girl presented with tinnitus caused by a high-flow AVF between the right extracranial vertebral artery and deep jugular vein arising(More)
Background. Vascular complications are a major cause of dysfunction or transplant loss in children. Arterial or venous occlusion, transplant renal artery stenosis (TRAS) and some arteriovenous (AV) fistula require rapid detection and prompt intervention. The present study was performed to determine the accuracy of colour Doppler sonography (CDS) in the(More)
PURPOSE To answer the question whether the TSI (tissue strain imaging) sonoelastography technique can contribute to the diagnosis of chronic renal allograft damage. MATERIAL AND METHODS A prospective study of 112 patients between June 2010 and April 2011 was conducted to compare elastography data with biopsy results and laboratory parameters in order to(More)
For the histological verification of suspicious non-palpable small breast tumors, the three-dimensional breast biopsy applied as cylindrical extirpation using the ABBI system is the optimal solution at present. Because of the possibility of performing mammography during the operation, errors of localization can be corrected and incorrect incisions avoided.(More)
Die Parotis ist ein seltener Manifestationsort einer Sarkoidose (6% aller Fälle). Die Wertigkeit der modernen sonographischen Bildgebung in der Diagnostik der Ohrspeicheldrüsensarkoidose (Heerfordt-Syndrom) soll dargestellt werden. Vier Patienten (3 m., 1 w., Alter 31–42 Jahre) wurden zur Abklärung einer unklaren Parotisschwellung in Kombination mit Fieber(More)
