Low sensitivity of transabdominal ultrasound
is obvious as this study was specific for periampullarytumors which are obscured on transabdominal ultrasound
by gas in the duodenum and large bowel.
Comparing IOUS with preoperative transabdominal ultrasound
, IOUS were able to identify more lesions that were previously undetected in seven out of the nine dogs, figure 1 shows examples of lesions detected by IOUS.
We retrospectively analyzed the radiation dose for all TIPS performed over a four-year period with transabdominal ultrasound
guidance for PV puncture (n=212, with 210 performed successfully and data available for 206); fluoroscopy time, dose area product (DAP) and skin dose were recorded.
can detect the embryo with its heart beat by day 27 of gestation .
showed a large distal pancreatic mass.
Caption: FIGURE 1: Transabdominal ultrasound
demonstrated sludge and stones in a contracted gallbladder.
Embryo transfer was performed under transabdominal ultrasound
guidance 2, 3, or 5 days after oocyte retrieval depending on the number and quality of the embryos available and the patient's will.
However, transabdominal ultrasound
was still the initial sonographic technique for routine evaluation of the female pelvis.
showed distended gall bladder with dilated intra- and extra-hepatic channels.
(36) reported a sensitivity of 84% and specificity of 60% for transabdominal ultrasound
in diagnosis of LBP with a cut-off spinal diameter of 14 mm; nevertheless, the use of transabdominal ultrasound
is limited due to anatomical restrictions like different abdominal tissues and oblique direction of the intervertebral discs as the major boundaries against ultrasonographic pulses at the level of L3-L4 and L5-S1 (37).
All women gave informed verbal consent for and had transvaginal ultrasound scan, but a transabdominal ultrasound
scan was also performed in the presences of a mass extending beyond the pelvis or failure to visualise the ovaries with the transvaginal probe.
All the women had at least one fibroid measuring 2 cm or larger based on transvaginal and/or transabdominal ultrasound
and a total uterine volume of [greater than or equal to] 160 mL by vaginal and abdominal ultrasound.
