CONTRAST RADIOGRAPHY OF THE PAROTID

Contrast radiography of the nasopharynx.

A technique of contrast radiography of the nasopharynx is described and indications for the procedure are reviewed. The main advantage of using this method is the simple and effective way it outlines the tumour mass and shows its response to therapy and any localized recurrences. Characteristic features of tumours at different sites are illustrated. The potential usefulness of this technique in...

An Estimate of Radiation Dose to the Lens of the Eyes, Parotid Gland, and Thyroid Gland in Dental Panoramic Radiography

Introduction: Dental panoramic radiography (DPR) is one of the most frequent diagnostic X-ray procedures, the application of which is currently on a growing trend. During DPR, several radiosensitive tissues, such as the lens of the eyes, parotid gland, and thyroid gland, contribute to the radiation field, and it is necessary to monitor their received dose. The aim of t...

Positioning long lines: contrast versus plain radiography.

AIM To assess the value of contrast versus plain radiography in determining radio-opaque long line tip position in neonates. METHODS In a prospective study, plain radiography was performed after insertion of radio-opaque long lines. If the line tip was not visible on the plain film, a second film with contrast was obtained in an attempt to visualise the tip. RESULTS Sixty eight lines were i...

Radiographic Contrast-Enhancement Masks in Digital Radiography

The Belfast experiment in direct access to contrast radiography.

The general practitioner working in his consulting room or his patient's home has a strictly limited range of diagnostic facilities available to supplement his clinical skills and experience. As long ago as 1946 the Annual Representative Meeting of the British Medical Association recommended that wherever possible, hospital departments of pathology and radiology should give direct access facili...
