The purpose of this study was to evaluate the diagnostic yield of core biopsy in coaxial technique under guidance of computed tomography (CT) for retroperitoneal masses. We performed a retrospective analysis of CT-guided coaxial core biopsies of undetermined masses in the non-organ-bound retroperitoneal space in 49 patients. In 37 cases a 15-G guidance(More)
PURPOSE To evaluate the suitability of semi-automated compared to manual tumor response assessment (TRA) of liver metastases. MATERIALS AND METHODS In total, 32 patients with colorectal cancer and liver metastases were followed by an average of 2.8 contrast-enhanced CT scans. Two observers (O 1, O 2) measured the longest diameter (LD) of 269 liver(More)
BACKGROUND Percutaneous cutting needle biopsy of focal liver lesions under CT guidance has established itself as a standard method. The purpose of this study was to evaluate which diagnostic quality can be achieved under guidance of multislice CT (MSCT) and with the use of different needle sizes. METHODS The data of 163 MSCT-guided core biopsies of focal(More)
The aim of this study was to demonstrate the feasibility of cranial nerve (CN II–XII) imaging with 7 Tesla magnetic resonance imaging (MRI). In this study four sequences were evaluated in three healthy volunteers using magnetization preparation rapid gradient echo (MPRAGE), constructive interference in steady state (CISS), true fast imaging with steady(More)
BACKGROUND The aim of this study was to evaluate liver volume variations (LVV) as a parameter to assess the therapy response in patients with advanced liver metastasis (aLM). METHODS Patients with colorectal cancer and consecutive computed tomography (CT) scans were divided into a group with aLM receiving palliative chemotherapy (n = 24) and a control(More)
Introduction In Western and Central Europe the incidence of tuberculosis is declining, however, it is still responsible for a high mortality in developing countries of Africa and South-East Asia [1]. In 2004 the incidence of tuberculosis in Germany was registered with eight per 100 000 habitants. In Germany 45.6% patients with tuberculosis had a history of(More)
Die perkutane Schneidbiopsie unklarer Leberherde unter CT-Kontrolle ist eine etablierte Methode. Wir wollten klären, welche diagnostische Qualität mit Hilfe der Mehrschichtcomputertomographie (MSCT) bei Verwendung verschiedener Nadelkaliber erreicht werden kann. Es wurden 163 Schneidbiopsien fokaler Leberläsionen unter MSCT-Kontrolle durchgeführt. In 121(More)
