Improved image quality and examination procedures in xeroradiographic peripheral angiography: an experimental study.

Ten dogs were used to compare conventional peripheral angiography and xeroradiographic angiography using three different concentrations of contrast material. Serial angiograms were produced in order to determine maximum arterial filling time, and a xeroradiograph was made at the predetermined maximal arterial phase. Xeroradiographic angiography consistently provided better imaging of the peripheral vessels and soft tissue. Reduction of the concentration of contrast material resulted in the loss of an image of diagnostic quality using conventional angiography, but vascular definition was maintained using xeroradiography. These studies indicate that xeroradiographic angiography not only improved peripheral vascular imaging, but is also successful at a lower concentration of contrast material, thus reducing toxic systemic effects and pain associated with the procedure.

Extracranial meningiomas of the head and neck.

Extracranial extraspinal meningiomas (less than 1% of all meningiomas) frequently occur in the head and neck. The radiographic findings of extracranial meningioma of the head and neck are not pathognomonic. However, the location of the tumor in the pathway of cranial nerves or adjacent to the skull base, the demonstration of a well circumscribed, solid, enhancing mass by computed tomography, and the faint tumor stain on arteriography should allow the radiologist to make a possible, although not definite, diagnosis of this rare tumor. Detection of possible intracranial extension and involvement of adjacent structures is mandatory before surgery.
