Simplified CT-guided stereotaxic biopsy.
A stereotaxic frame worn during computed tomographic (CT) scanning of the head produces landmarks in each section that are used to relate section coordinates to frame coordinates. A small, commercially available, programmable calculator is used to interrelate frame and CT section geometry. The system can be used with any CT scanner that can specify (x,y) coordinates of a pixel, obviating the ne...
متن کاملCombined use of stereotaxic CT and angiography for brain biopsies and stereotaxic irradiation.
A Riechert Mundinger stereotaxic device was modified to enable artifact-free computed tomographic (CT) scanning with the stereotaxic frame attached to the patient's head. A localization system was developed allowing determination of the XYZ coordinates of the target point directly from the CT cut. Angiography was performed intraoperatively with the stereotaxic frame attached. Coronal and sagitt...
متن کاملMediastinal hematoma following transbronchial needle aspiration.
the interpolated retrograde P waves, the retrograde limb of a SAN reentry in the SAN junction probably would also have been blocked. Therefore, it’s highly unlikely the NPs occur as a result of SAN reentry with a failure to depolarize the left atrium. However, the NPs may represent right atrial depolarizations in left atrial P waves originating near the left atrial termination of BB (Fig 82) wh...
متن کاملAccuracy of stereotaxic localisation using MRI and CT.
The accuracy of stereotaxic coordinates determined using the Leksell apparatus with CT and MRI was investigated using an Agar filled head phantom. Both imaging techniques were found to produce an accuracy of better than 2 mm with the exception of the Z coordinate as measured by CT (2.3 mm). This latter error is greater because of the 3 mm slice width used. Direct coronal views were used to dete...
متن کاملAcute subdural hematoma mimicking epidural hematoma on CT.
The characteristic feature of acute subdural hematoma (ASDH) when located over the convexity is that of a hyperdense crescentic area that conforms to the underlying cerebral surface and extends over most of the subdural space. Epidural hematoma (EDH), on the other hand, adopts a biconvex shape that is fundamentally focal in nature. During a 4V2year period two of 25 operatively proven cases of A...
