Background: Spinal merging has been done with preoperative CT scans merged with fluoroscopic imaging. However, preoperative and intraoperative CT scans have not been merged for the purposes of transferring a plan. If spine surgeons can create the optimal surgical pathway before surgery and then merge the pre-planned pathway onto the real patient CT scan in the operating room, the result will be...

so that specific treatment can be started. The cord sign (hyperdense thrombosed veins on unenhanced CT) and the empty-delta sign (a filling defect in the superior sagittal sinus on enhanced CT) are considered pathognomonic for SVT.

A 54-year-old otherwise healthy Caucasian male was referred to us for further management of an enlarging left heterogeneous peri-renal mass. The patient had been initially followed with serial imaging by his primary care physician, who had been monitoring the mass since it was first detected 2 years earlier, when it was 2.9cm in size. Most recent CT scan showed a 4.7 cm mass, located posteriorl...

Case report A 24-year-old man with no previous medical or surgical history presented with a history of colicky central abdominal pain, distension, nausea and vomiting. He was admitted to intensive care and was on renal support at the time the computed tomography (CT) scan was requested. The inflammatory markers and serum amylase level were raised. The post-contrast CT scan demonstrated proximal...

The authors present a rare case of lumbar vertebral hemangioma extending to the epidural space with a bisected appearance and impinging on thecal sac. This 52-year-old lady presented with one year history of low back pain and bilateral leg radiation. Plain radiography showed vertical linear streaks at L2 vertebral body and axial computed tomography (CT) scan revealed small "polka dot" appearanc...

The aim of this study was to determine the reliability of magnetic resonance imaging (MRI) in the assessment of facet tropism and facet arthrosis of spondylolisthesis levels in degenerative cervical spondylolisthesis as compared to computed tomography (CT). The discrepancies in the interpretation of CT and MRI data in the evaluation of facet tropism and arthrosis have given rise to questions re...

An axial computed tomographic (CT) scan of the lumbosacral regions was performed in 65 patients. The patient population was divided into two groups. The first (control) group included 40 elderly patients without calcification of the ligamenta flava. The second group included 25 patients with ankylosing spondylitis. More than 90% of those in the second group showed calcified lumbosacral ligament...

Figure 1: Computed tomography (CT) scan of the chest. Axial image (A) shows a 2 × 3 cm mass in the anterior mediastinum and a tumour thrombus occluding the SVC and the azygos vein (arrows). On CT scan, the mediastinal mass does not have any connection either with the LBV or with the SVC. This unusual intravascular growth is due to the spread of the tumour into the LBV and SVC through the thymic...

by producing undistorted three-dimensional images of the area under examination, cone-beam computed tomography (cbct) systems have met many of the limitations of conventional radiography. these systems produce images with small field of view at low radiation doses with adequate spatial resolution that are suitable for many applications in endodontics from diagnosis to treatment and follow-up. t...
