Three experiments were conducted to determine gestational age in the ewe and doe by measuring placentomes with a B-mode ultrasonograph and a 5 MHz transducer. Transrectal measurements were obtained by placing the female over a bale of hay. In Experiment 1, ewes (n = 12) and does (n = 15) were examined by transrectal ultrasonography every week from breeding to parturition to determine the growth...

The aim of the present study was to determine follicle development and resumption of ovarian activity in Bulgarian Murrah buffaloes by transrectal ultrasonographic monitoring of the ovaries during the first 50 days after after calving throughout the breeding season. The investigation included 18 clinically healthy Bulgarian Murrah buffaloes divided into two groups: Group I (n=8, primiparous buf...

Ultrasonographic fetal eye measures have been used to estimate gestational age of the fetus in light horse mares. However, fetal eye measures have not been published for smaller pony breeds. This study was conducted to develop reference ranges for ultrasonographic measures of fetal eyes in small ponies for the purpose of predicting days before parturition (DBP) when breeding or ovulation dates ...

Background: Transrectal ultrasound (TRUS) is a cost-effective test for preoperative assessment of rectal cancer. However, whether the accuracy of TRUS staging is correlated with tumor location remains obscured. This study is designed to explore their relationship and confirm an optimal application of TRUS in rectal cancer restaging. Methods: From 2005 to 2011, rectal cancer patients with TRUS d...

Eighteen cyclic Shiba goats were used in this study. Estrus was synchronized with a single injection of 125 microg of a synthetic analogue of prostaglandin F(2)alpha (PGF(2)alpha) after detection of at least one corpus luteum by B-mode ultrasonography. Blood samples were collected from each animal on days 0, 7 and 21 post-mating for progesterone assay. Animals in estrus were either allowed to b...

OBJECTIVE To evaluate the correlations between prostate volumes estimated by transabdominal, transrectal, and three-dimensional US and the factors affecting the differences. MATERIALS AND METHODS The prostate volumes of 94 consecutive patients were measured by both transabdominal and transrectal US. Next, the prostate volumes of 58 other patients was measured by both transrectal and three-dim...

PURPOSE The reliability and objectivity of computer assisted transrectal ultrasound are examined. MATERIALS AND METHODS Pathological examination of radical prostatectomy specimens was compared prospectively to automated cancer detection in corresponding transrectal ultrasound images. RESULTS For automated cancer detection, a sensitivity of 0.75 and a specificity of 0.78 were obtained. Moreo...

background : a transrectal ultrasound-guided prostate biopsy is currently the gold standard procedure to detect prostatic adenocarcinoma. there is little information on the clinical utility of this technique for the detection of prostate adenocarcinoma in men with suspected prostate cancer in pakistan. this study seeks to determine the frequency of prostatic adenocarcinoma by using a transrecta...
