PURPOSE The purpose of this study was to evaluate the magnetic resonance prostate imaging reporting and data system (PI-RADS) for the detection of prostate cancer by the results of magnetic resonance imaging (MRI)-guided biopsy of the prostate as a reference standard. PATIENTS AND METHODS In 55 patients who had undergone MRI-guided biopsy of the prostate,(More)
We identified collagen triple helix repeat containing-1 (Cthrc1) as a novel gene expressed in the adventitia and neointima on arterial injury and found that it functionally increases cell migration while reducing collagen deposition. To address the in vivo role of Cthrc1, we generated transgenic mouse lines that constitutively overexpress Cthrc1. An(More)
PURPOSE To review the tolerability and diagnostic effectiveness of gadoteric acid under daily practice conditions in the general population and at-risk patients. MATERIALS AND METHODS A total of 84,621 patients (45.4% men, 54.6% women, mean age 52.0 ± 16.9 years) were studied in 129 German centers. Patients underwent contrast-enhanced magnetic resonance(More)
OBJECTIVE We evaluated the precision of helical MDCT for the quantification of mitral valve stenosis (MVS) compared with transthoracic echocardiography (TTE) and cardiac catheterization. MATERIALS AND METHODS A total of 28 patients with MVS of differing severity underwent an ECG-gated contrast-enhanced MDCT scan. The mitral valve area (MVA) was determined(More)
BACKGROUND The ability to non-invasively analyze tumor aggressiveness is an important predictor for individual treatment stratification and patient outcome in prostate cancer (PCA). PURPOSE To evaluate: (i) whether apparent diffusion coefficient (ADC), the T2 signal intensity (SI), and a combination of both parameters allow for an improved discrimination(More)
PURPOSE To evaluate an irregular perilesional hyperechoic zone as a potential criterion of malignancy on breast ultrasound and to test whether this zone correlates with perilesional T2 hyperintensity on magnetic resonance imaging (MRI). MATERIALS AND METHODS A total of 137 patients (85 malignant lesions, 52 benign lesions) who underwent breast ultrasound(More)
The inhibitor of apoptosis protein survivin is highly expressed in neuroblastoma (NB) and survivin-specific T cells were identified in Stage 4 patients. Therefore, we generated a novel survivin minigene DNA vaccine (pUS-high) encoding exclusively for survivin-derived peptides with superior MHC class I (H2-K(k)) binding affinities and tested its efficacy to(More)
We recently identified collagen triple helix repeat containing-1 (Cthrc1) as a novel gene induced in adventitial fibroblasts after arterial injury. Cthrc1 is a 30 kDa secreted protein that has the ability to inhibit collagen matrix synthesis. Cthrc1 is also glycosylated and retains a signal sequence consistent with the presence of Cthrc1 in the(More)
To assess active myocardial inflammation by cardiovascular magnetic resonance (CMR) and endomyocardial biopsy (EMB) amongst adult patients with dilated cardiomyopathy (DCM). We evaluated 23 adults with chronic DCM, who had successfully undergone both CMR and EMB within 3.5 ± 2.6 days. EMB was considered the gold standard. CMR assessment of myocardial(More)
OBJECTIVE To examine the value of additional transrectal ultrasonography (TRUS)-guided random biopsy (RB) in patients with negative magnetic resonance imaging (MRI)/ultrasonography (US) fusion-guided targeted biopsy (TB) and to identify possible reasons for TB failure. PATIENTS AND METHODS We conducted a subgroup analysis of 61 men with prostate cancer(More)
