Purpose To evaluate preoperative magnetic resonance imaging (MRI) criteria for their ability to predict the complete removal of parasellar pituitary macroadenoma on the 3-month postoperative MRI. Methods Dedicated pre- and postoperative pituitary MRI studies were reviewed in 49 patients who had undergone transsphenoidal surgery for macroadenomas with potential unilateral parasellar involvement....

Depiction of temporal information and examination of temporal knowledge are essential for effective temporal reasoning in medical analysis systems which are attaining significance recently. These temporal representation models afford attributes for temporal rules mining through association rule extraction which are necessary to perform detective inference in medical expert systems. Existing tem...

To determine the role of real-time spatial compound imaging in breast ultrasound (US), 38 patients with a total of 50 benign changes (fibroadenomas, cysts, lactiferous duct dilatation) underwent both conventional B-mode US and real-time spatial compound imaging under standardized examination settings. Subsequently, images were reviewed independently by three readers experienced in breast US and...

For the rupture risk assessment of cerebral aneurysms, the blood flow is approximated using computational fluid dynamics (CFD). Unsteady CFD inflow conditions yield time-dependent vector fields, from which the wall shear stress (WSS), an important indicator for rupture risk in clinical research, is extracted. For WSS evaluation, its magnitude is usually color-coded on the aneurysm surface mesh....

Parsing is the process of structuring a l inear depiction in accordance with a g iven grammar. The “linear depiction” may be a language sentence, a computer program, a weaving pattern, a sequence of biological strata, a part of music, actions in a ritual performance, in short any linear chain in which the preceding elements in some way confine the next element. Parsing with finite automata netw...

Nowadays, model-based test approaches are indispensable for the quality assurance of invehicle control software. In practice, the Classification-Tree Method for Embedded Systems (CTMEMB) is used to realize a compact graphical representation of test scenarios. Up to now, the CTMEMB has been used mainly in the area of continuous systems. Though the depiction of events within test scenarios is pos...
