BACKGROUND Contrast-enhanced magnetic resonance imaging (MRI) is highly sensitive for assessing temporomandibular joint (TMJ) involvement in juvenile idiopathic arthritis (JIA), but only sparse data exist on normal TMJ appearance in children. PURPOSE To determine normal MRI appearance and enhancement pattern of pediatric TMJ as basis for diagnosing early(More)
The objective of this study was to demonstrate the feasibility of 3D proton MR spectroscopic imaging (MRSI) of the prostate using a standard spine instead of a dedicated endorectal coil at 1.5 T. Twenty-eight patients (25 with biopsy proven prostate cancers and three patients with a benign prostate hyperplasia) were examined. MRI and MRSI were conducted(More)
Tumor bed stereotactic radiosurgery (SRS) after resection of brain metastases is a new strategy to delay or avoid whole-brain irradiation (WBRT) and its associated toxicities. This retrospective study analyzes results of frameless image-guided linear accelerator (LINAC)-based SRS and stereotactic hypofractionated radiotherapy (SHRT) as adjuvant treatment(More)
BACKGROUND AND PURPOSE BCT is a benign entity, whose appearance on conventional MR imaging makes its differentiation from neoplastic, inflammatory, or subacute ischemic disease challenging. SWI is sensitive to susceptibility effects from deoxyhemoglobin with excellent spatial resolution. Only scarce case reports have described the utility of SWI in cases of(More)
OBJECTIVES Aim of this study was to compare the utility of susceptibility weighted imaging (SWI) with the established diagnostic techniques CT and fluid attenuated inversion recovery (FLAIR) in their detecting capacity of subarachnoid hemorrhage (SAH), and further to compare the combined SWI/FLAIR MRI data with CT to evaluate whether MRI is more accurate(More)
OBJECTIVE The objective of this study was to evaluate the changes in oxygenation of prostate cancer induced by carbogen breathing using blood oxygen level-dependent (BOLD) magnetic resonance image (MRI) with an endorectal coil (eMRI). MATERIALS AND METHODS In 32 patients with biopsy-proven prostate cancer, endorectal MRI was performed at 1.5 Tesla using(More)
To investigate pathological findings in the susceptibility weighted imaging (SWI) of patients experiencing convulsive (CSE) or non-convulsive status epilepticus (NCSE) with focal hyperperfusion in the acute setting. Twelve patients (six with NCSE confirmed by electroencephalogram (EEG) and six patients with CSE with seizure event clinically diagnosed)(More)
OBJECTIVE Procalcitonin (PCT) is currently recommended as a suitable parameter to detect and to evaluate the course of bacterial, fungal or parasitic infections. However, recent studies provide evidence that surgical trauma and humoral mediators of inflammation, respectively,may induce PCT synthesis, thereby reducing the validity and reliability of PCT as(More)
Fragestellung. Procalcitonin (PCT) wird derzeit als Laborparameter zur Detektion und Verlaufsbeobachtung bei bakteriellen, fungalen oder parasitären Infektionen empfohlen. Untersuchungen weisen jedoch auf eine Beeinflussung der PCT-Plasmakonzentrationen durch das Operationstrauma bzw.durch humorale Mediatoren im Rahmen einer systemischen Inflammation hin,(More)
