Reduction of radiation exposure to the cardiologist during coronary angiography by the use of a remotely controlled mechanical pump for injection of contrast medium.

Selective coronary cineangiography was carried out in 103 consecutive patients. In half the examinations (53) injection of contrast medium was performed by hand using a syringe, with the cardiologist standing in the usual position next to the X-ray table. In the other half (50) contrast medium was injected by a remotely controlled mechanical pump whilst the cardiologist stood well away from the X-ray source. Radiation dose to the lens of the cardiologists eye was estimated for the two groups by measurement of head badge dosimetry. In the first group (hand injection) total radiation dose was 1.30 mSv; in the second group (mechanical injection) it was reduced five-fold, to 0.25 mSv. This technique therefore represents an important means of achieving substantial reductions in radiation exposure to cardiologists.

Comparison of gray-scale and B-color ultrasound images in evaluating left ventricular systolic function in coronary artery disease.

To confirm whether or not echocardiographic B-color images (temperature, magenta, rainbow) are superior to ordinary gray-scale images, 62 coronary artery disease (CAD) patients (42 men and 20 women) underwent gray-scale and B-color echocardiography and cineangiography within 24 hours. Left ventricular (LV) volume was derived from angiography using the single-plane area-length method and was derived from echocardiography using single-plane modified Simpson's formula. In predicting angiographic volume, the correlations between B-color images and angiography were similar to that between the gray-scale image and angiography. In evaluating LV ejection fraction, the correlation coefficients between B-color images and angiography (temperature r = 0.93, magenta r = 0.93, rainbow r = 0.92) were slightly higher than that between the gray-scale image and angiography (r = 0.85) (p less than 0.05). We conclude that B-color images yield estimates of LV volumes that are of similar accuracy to gray-scale images in patients with CAD.
