Visualization of Lenticulostriate Arteries on CT Angiography Using Ultra-High-Resolution CT Compared with Conventional-Detector CT

Simultaneous cervical CT angiography from routine contrast-enhanced neck CT with multi-detector CT scanning

84 ● M a r t 2 0 0 1 C omputed tomographic angiography (CTA) is a technique that has evolved in a rapidly changing interplay of hardware and software advances. CT scan times are becoming ever shorter, now allowing imaging of larger segments of arterial anatomy during circulation of the intravenous bolus of contrast material. Multidetector (or multislice) CT is the most recent dramatic advance t...

Evaluation of CSF leaks: high-resolution CT compared with contrast-enhanced CT and radionuclide cisternography.

BACKGROUND AND PURPOSE Radiologic evaluation of CSF leaks is a diagnostic challenge that often involves multiple imaging studies with the associated expense and patient discomfort. We evaluated the use of screening noncontrast high-resolution CT in identifying the presence and site of CSF rhinorrhea and otorrhea and compared it with contrast-enhanced CT cisternography and radionuclide cisternog...

Flat panel detector CT, CT angiography, and CT perfusion in stroke.

Anatomical Evaluation of Renal Arteries and Veins in Kidney Donors by CT Angiography

Abstract Background: Renal transplantation (RT) is the transplantation of a kidney into a patient with end-stage renal disease and has become the treatment of choice for most patients with end-stage renal disease. The knowledge of renal vascular variations is of a great importance for the surgeons who approach the kidneys from the retroperitoneal o...

Improved arterial visualization in cerebral CT perfusion-derived arteriograms compared with standard CT angiography: a visual assessment study.

BACKGROUND AND PURPOSE Invasive cerebral DSA has largely been replaced by CTA, which is noninvasive but has a compromised arterial view due to superimposed bone and veins. The purpose of this study was to evaluate whether arterial visualization in CTPa is superior to standard CTA, which would eliminate the need for an additional CTA scan to assess arterial diseases and therefore reduce radiatio...
