The purposes of this study were to evaluate the accuracy of the ultrasonographic measurements used during diagnosis of hypertrophic pyloric stenosis (HPS), to examine the relationship between the palpability and the morphologic features of the pyloric mass, and to show the morphologic resolution of the pylorus after pyloromyotomy. ⋯ The preoperative ultrasonographic measurements of the pylorus reliably evaluated the pyloric muscle thickness and diameter in HPS. The actual pyloric diameter correlated with the palpability of the pyloric mass. The morphologic resolution of the pylorus after surgery did not correlate with the prompt improvement of symptoms.

The TER system is a robot-based tele-echography system allowing remote ultrasound examination. The specialist moves a mock-up of the ultrasound probe at the master site, and the robot reproduces the movements of the real probe, which sends back ultrasound images and force feedback. This tool could be used to perform ultrasound examinations in small health care centers or from isolated sites. The objective of this study was to prove, under real conditions, the feasibility and reliability of the TER system in detecting abdominal aortic and iliac aneurysms. ⋯ Our study on 58 patients suggests that the TER system could be a reliable, acceptable, and effective robot-based system for performing remote abdominal aortic ultrasound examinations. Research is continuing to improve the equipment for general abdominal use.

Randomized Controlled Trial
A randomized controlled trial of ultrasound-assisted lumbar puncture.
Evidence showing the systematic utility of ultrasound imaging during lumbar puncture (LP) in the emergency department is lacking. Our hypothesis was that ultrasound-assisted LP would increase the success rate and ease of performing LP with a greater benefit in obese patients. ⋯ The use of ultrasound for LP significantly reduced the number of failures in all patients and improved the ease of the procedure in obese patients.

The purpose of this study was to evaluate the potential importance and need for further investigation of thyroid lesions detected during imaging investigations unrelated to the thyroid gland (thyroid incidentalomas). The management of these lesions is controversial because most malignancies detected will be papillary microcarcinomas, which will not manifest as overt disease. ⋯ The management and importance of the thyroid incidentaloma remain controversial, although problems relating to these issues are likely to become increasingly common in radiologic practice. Once an incidentaloma has been observed, formal clinical and sonographic assessment should be considered, with fine-needle aspiration cytologic examination as appropriate, after an informed discussion with patient.
