[Retracted] Study on Various Luteal Characteristics Using Doppler Ultrasonography for Early Pregnancy Diagnosis in Nili-Ravi Buffaloes

Figure 1

Representative ultrasound images of corpus luteum (CL) in Nili-Ravi buffaloes on day 5 postinsemination. (a) B-mode ultrasound image of CL taken by 7.5 MHz transrectal transducer. (b) Color Doppler image depicting luteal blood flow of day 5 postinsemination CL. (c) Power Doppler image depicting luteal blood flow of Day 5 post-insemination CL. The white dotted circles indicate the area of interest (AOI) used to calculate the cross-sectional area of the CL. Within the AOI, the coloured pixels were quantified using image J software (National Institute of Health, Bethesda, MD, USA) to assess the luteal blood flow.
