Twin pregnancies recorded in German Thoroughbred mares were responsible for premature termination of 2.5% of 27 465 pregnancies between 1967 and 1992, and constituted 38.5% of all 1788 abortions (6.5% of all pregnancies) recorded over the same time. Over time, the rate of twin pregnancies dropped from 2.7% before 1984 to 1.7% thereafter (P<0.001). During the last 20 years several methods of treatment of early detected twin pregnancies were evaluated. Crushing of one embryo in 69 cases gave best results when conducted between Days 21 to 26 of pregnancy, resulting in 80% single gestations continuing. Curtailing food intake during early twin pregnancies to enforce regression of the weaker conceptus is difficult to manage. However, reducing feed intake for one cycle prior to breeding in three mares with histories of frequent twin pregnancies resulted in five single pregnancies in five attempts. 相似文献

The purpose of this article is to provide a survey of the diagnostic use of transcutaneous sonographic examination of the urogenital tract of pet birds. Possibilities and limitations in imaging normal and altered components of this organ system are discussed. Ultrasonographic examination of the avian urogenital tract was evaluated in 386 pet birds. Abnormal clinical signs were present in 289 birds; 97 birds were normal. Transcutaneous ultrasonography proved to be a useful, noninvasive, and fast diagnostic tool, especially in imaging laminated eggs and changes of the oviduct. Until now, these pathologic changes were not diagnosable in birds with other common noninvasive methods (e.g. radiography). The imaging of low-grade changes of the oviduct, disorders of the kidney without enlargement of the organ, as well as roughening of the egg shell proved to be difficult. Sonographic imaging of neither the normal kidney nor the inactive gonads was possible. 相似文献

A specially designed radio frequency receiver coil was used in a low-field-strength (0.1 T) magnetic resonance imager to improve the image quality of the Beagle brain. The aim was to obtain better distinction of anatomic details with a better signal-to-noise ratio in shorter imaging time. The spin-echo (TR/TE = 1200/100; TR is the repetition time and TE is the echo time in ms) brain images of three Beagles indicate that the new receiver coil can fulfill these goals. 相似文献

The sensitivity of conventional radiography for lesions of the cribriform plate, naso-orbital wall, lateral nasal wall and hard palate was investigated in 13 canine cadaver heads by creating measured defects in these structures. The location of the perforations were marked with a thin copper wire and the radiographic appearance of the defects was evaluated retrospectively by a single reviewer. Despite demarcation cribriform plate destruction of 2 mm could not be detected. Defects of 3 mm were detected in only 2 heads, 4 mm defects in 1 further head, an oblong 4 x 10 mm defect in 7 heads and in the remaining 3 heads only a 10 x 10 mm defect became visible as such. The naso-orbital wall had to be destroyed in its whole vertical length for detection of a defect in ventrodorsal or dorsoventral views. Therefore conventional radiography is of low diagnostic value for these lesions. Defects of 2 mm in the lateral nasal wall and the hard palate could be detected confidently in all heads indicating high sensitivity of conventional radiography. Soft tissue opacification did not alter the detectability of any nasal border structure lesion. 相似文献
