Angiotomogrphy: a preliminary report.

Angiotomography is a coined to denote the use of body-section radiography in conjunction with arteriography. It has been used initially to augment visualization of portions of the abdominal aorta and its branches, made radiopaque by the intravenous injection of contrast material. Technic Arterial Opacification: The method of intravenous opacification follows closely the technic described by Steinberg et al. Number 12 Robb-Steinberg needles are placed either percutaneously or by cut-down in antecubital veins bilaterally. After an arm-to-tongue circulation time has been determined with Decholin, a bolus of warmed contrast material (Hypaque 85 per cent) is injected rapidly into each arm. The total dosage is 100 c.c. divided equally between two 50-c.c. syringes. Opacification of the abdominal aorta will be optimal at a time one to two seconds greater than the measured circulation time. Perfusion of abdominal organs takes place immediately subsequent to that event. Tomography Cassette: With a Siemens multisect...
