Prenatal diagnosis of LUTO: how to improve diagnostic accuracy
This research study proposes a 5-element clinical score for discriminating lower urinary tract obstruction (LUTO) from non-obstructive megacystis. In the study the clinical score performed better than the classic ultrasound triad of megacystis, keyhole sign and hydronephrosis.

Primary Care Physicians Demonstrate High Diagnostic Accuracy When Performing Compression Ultrasound for DVT
In this prospective study compression US performed by general practitioners had a sensitivity of 90.0%, specificity of 97.1% and a diagnostic accuracy for DVT of 95.8%. The authors conclude that even in the hands of physicians not expert in vascular US, compression US can be a reliable tool.

Ultrasound + MRI good enough to replace surgery for diagnosis of deep endometriosis
The current gold standard for diagnosis of deep endometriosis is laparoscopic surgery. This review study found that transvaginal sonography combined with MRI could replace surgery for diagnosis of rectosigmoid endometriosis and could provide at least triage value for other locations.

141 women at risk for infections after transvaginal ultrasounds at Edmonton clinic, officials warn
Human error is being blamed for what health officials are calling a possible lapse in cleaning and disinfection procedures. This includes inconsistent tracking and documentation of the number of reprocessed probes available for endovaginal ultrasounds and overscheduling of procedures, AHS said.

Patients prefer TVUS to MRI for pelvic imaging
Providers often turn to transvaginal ultrasound (TVUS) and MRI when women are experiencing pelvic pain or abnormal uterine bleeding. Which of these imaging modalities is preferred among women? A team of researchers studied that exact topic, publishing their findings in Academic Radiology.

Virtual touch quantification accurate, noninvasive liver stiffness measurement
Virtual touch quantification with acoustic radiation force impulse (ARFI) demonstrated comparable if not superior accuracy to fibrosis-4 index and aminotransferase-to-platelet ratio index. However, when skin liver capsule distance is longer than 17.5 mm, there may be measurement failures.

The Force is Strong: Amputee Controls Individual Prosthetic Fingers Using Ultrasound Sensors
Luke Skywalker’s bionic hand is a step closer to reality for amputees in this galaxy. Researchers at the Georgia Institute of Technology have created an ultrasonic sensor that allows amputees to control each of their prosthetic fingers individually.

Use of ultrasound for the palpable undescended testis: a wasteful practice
Many primary care physicians order an ultrasound before referral to specialist care for suspected undescended testis; however, the value of this practice is questionable. In this retrospective study the authors conclude that ultrasound should not be routinely ordered in these cases.

3-D ultrasound imaging using a single sensor instead of thousands
The new technique involved creating a disk with bumps on it of varying heights across its surface and then sending the sound waves through the disk which is rotated on successive pulses. The technology is still at the lab bench stage but shows promise for use in future low-cost instruments.

Molecular beacon signals low oxygen with ultrasound
Researchers have developed an oxygen-sensitive photoacoustic molecule (a molecular beacon) that emits ultrasound signals in response to light in a process called photoacoustic imaging. The molecules only respond to stimulation when they are in a low oxygen environment,
