DETERMINATION OF BONE MINERAL DENSITY OF THE DISTAL EXTREMITY OF THE RADIO IN ROTTWEILER, BY RADIOGRAPHIC OPTIC DENSITOMETRY

Abstract

This study allowed the standardization of the bone mineral density (BMD) of the distal extremity of the radio of 36 dogs adults in Rottweiler breed by radiographic optic densitometry. The limbs of the animals were radiographed with scale of aluminum that served as a reference. The radiographies images were digitalized and analyzed by a computer program for comparison of gray tones between the standard image and the image of the reference scale radiographed with the bone. Afterwards the values of density were expressed in millimeters of aluminum. Also studied the correlations between BMD and the sex, weight and external measures as the length of spine, height of the animal and circumference the distal extremity of the limb in study. The mean values and standard deviations of the bone mineral density of the distal extremity of the radio were: for the metaphysary region the average of BMD of 7,88±0,89 mmAl, the diaphysary region 1 the average of BMD of 8,58±0,80 mmAl and for diaphysary region 2 of BMD of 9,00±0,74 mmAl.
