LYMPHANGIOGRAPHY, CAVOGRAPHY, AND UROGRAPHY; COMPARATIVE ACCURACY IN THE DIAGNOSIS OF PELVIC AND ABDOMINAL METASTASES.

During the past few years, interest has been increasing in lymphangiography as a method of demonstrating abnormalities in lymph nodes and lymphatic channels (8, 10, 13, 14). Oncologists have exhibited a special enthusiasm for this new procedure since it affords a graphic representation of the site and extent of pelvic and abdominal cancer. Prior to the application of lymphangiography, the presence of retroperitoneal masses not detectable on physical examination was inferred from obliteration of the psoas shadows or delineation of a soft-tissue mass on the plain films of the abdomen; the secondary changes produced in the gastrointestinal tract during the course of a barium meal; displacement of either kidney or ureter during intravenous urography; the use of retroperitoneal air insufflation (2, 6); and, more recently, the displacement of the cava as shown by inferior vena cavography (5). The ease with which most of the above procedures can be performed enhances their appeal, particularly when compared with...

Arteriography in diagnosis of abdominal disease.

Selective arteriography is a valuable aid in the diagnosis of otherwise obscure gastrointestinal disorders. Its usefulness is described with particular reference to lesions of the liver, pancreas and spleen and primary disorders of the gastrointestinal arterial system. Percutaneous selective arteriography of the celiac and the mesenteric arteries has been successfully applied in the preoperative determination of the site of gastrointestinal bleeding.
