Early pregnancy diagnosis at 21 days post artificial insemination using corpus luteum vascular perfusion compared to corpus luteum diameter and/or echogenicity in Nelore heifers
The objective was to compare the use of corpus luteum (CL) vascular perfusion to CL diameter and/or echogenicity to diagnose pregnancy at 21 d after timed-AI. Ovaries of Nelore heifers were assessed using ultrasonography in B-mode and color Doppler simultaneously 21 d after timed-AI (n = 113). Objec...

| description | The objective was to compare the use of corpus luteum (CL) vascular perfusion to CL diameter and/or echogenicity to diagnose pregnancy at 21 d after timed-AI. Ovaries of Nelore heifers were assessed using ultrasonography in B-mode and color Doppler simultaneously 21 d after timed-AI (n = 113). Objective evaluations were performed using an image processing software to extract the number of colored pixels (ColorPix), diameter (mm) and echogenicity/mm² (EchoPix) of the CL. Subjective evaluations of the CL were performed by five evaluators using scores of estimated vascular perfusion area of color Doppler scan videos and estimated CL size and qualitative echogenicity of B-mode scan videos. The reference pregnancy diagnosis was performed 33 d after timed-AI using an ultrasonic device. Corpus luteum ColorPix, diameter and EchoPix were highly correlated (P |

Pregnancy diagnosis accuracy, sensitivity, and negative predictive value were not different for CL ColorPix and diameter and was less with use of EchoPix compared to the other parameters. Size and vascular perfusion scores were correlated to the greatest extent (0.88–0.94) with the respective objective values within evaluator. The results from the ROC curve analysis indicated a smaller area under the curve for qualitative echogenicity compared to CL size and vascular perfusion. Corpus luteum vascular perfusion was the only subjective evaluation that when assessed there were no false negative pregnancy diagnoses. In conclusion, the use of the objective CL diameter resulted in the same efficacy as CL vascular perfusion evaluations for early pregnancy diagnosis in Nelore heifers.</description><identifier>ISSN: 0378-4320</identifier><identifier>EISSN: 1873-2232</identifier><identifier>DOI: 10.1016/j.anireprosci.2019.106144</identifier><identifier>PMID: 31514923</identifier><language>eng</language><publisher>Netherlands: Elsevier B.V</publisher><subject>Animals ; Bovine ; Cattle ; Corpus luteum ; Corpus Luteum - blood supply ; Corpus Luteum - cytology ; Corpus Luteum - diagnostic imaging ; Early Diagnosis ; Estrus Synchronization ; Female ; Insemination, Artificial - veterinary ; Organ Size ; Predictive Value of Tests ; Pregnancy ; Pregnancy diagnosis ; Pregnancy Tests - methods ; Pregnancy Tests - veterinary ; Pregnancy, Animal ; Regional Blood Flow ; Sensitivity and Specificity ; Time Factors ; Ultrasonography - methods ; Ultrasonography - veterinary ; Ultrasound</subject><ispartof>Animal reproduction science, 2019-10, Vol.209, p.106144-106144, Article 106144</ispartof><rights>2019 Elsevier B.V.</rights><rights>Copyright © 2019 Elsevier B.V.
