79 ± 15.43. The main, right, and left portal vein diameter in patients with chronic liver disease was 14.51 ± 0.78 mm, 6.83 ± 0.81 mm, and 6.26 ± 0.74 mm, which were higher than those of their control. The portal vein diameter positively correlated (weak) with age and respiratory phases among participants (
 < 0.05).

This study found the main, right, and left portal vein diameter among patients with chronic liver disease to be larger than those of the controls. Ultrasonography is a reliable diagnostic tool in evaluating portosystemic pathologies.

Optimising abdominal aortic aneurysm surveillance intervals will improve current surveillance programmes. selleck products To the author's knowledge, no known study has exclusively asked patient opinion with regards to their surveillance interval. The aim of this study was to therefore determine a patient's perspective of their optimal intervals, encouraging shared decision-making and creating a patient-focused service.

Fifty patients, currently under abdominal aortic aneurysm surveillance, were interviewed. Patients were asked their opinions before and after seeing a patient decision aid. A patient decision aid presents information of risk in an easy-to-understand format. This specific patient decision aid, designed and created for this study, informed patients of the 'risk of exceeding the 5.5 cm surgical threshold' with regards to various surveillance intervals. The chosen optimal surveillance interval was recorded for each patient, and a median interval was calculated for each abdominal aortic aneurysm group. Groups wnicating, to the patient, the risk of the proposed changes and thus alleviating potential anxiety.
Overall, patients in abdominal aortic aneurysm groups 3.0-3.4 cm and 4.5-4.9 cm would choose to lengthen abdominal aortic aneurysm surveillance intervals. Lengthening the current surveillance intervals to 24 months (currently 12 months) for abdominal aortic aneurysm group 3.0-3.4 cm and to 6 months (currently 3 months) for abdominal aortic aneurysm group 4.5-4.9 cm would not only increase capacity but also reflect the needs and wishes of those using the National Health Service. The use of a patient decision aid is an effective way of communicating, to the patient, the risk of the proposed changes and thus alleviating potential anxiety.
The aims of this study were (1) Determine the effect on student ultrasound scanning skills using a lower extremity venous ultrasound phantom in addition to standard teaching methods of didactic lecture and scanning live volunteers and (2) Determine the effect of using a lower extremity venous ultrasound phantom in addition to standard teaching methods of didactic lecture and scanning live volunteers on student confidence levels in performing the lower extremity venous ultrasound examination.

Participants were first year diagnostic medical sonography students with minimal scanning experience (
 = 11), which were randomized into two groups. Group 1 (
 = 5) received the standard didactic lecture and attended a scan lab assessment where they performed a lower extremity venous examination on a human volunteer. Group 2 (
 = 6) received the standard didactic lecture, performed three scheduled scanning sessions on an anatomic lower extremity venous phantom with flow and then attended the same scan lab assessment as Group 1, where they performed a lower extremity venous examination on a human volunteer.

Scan lab assessments on day 4 of the study demonstrated a significant difference in scanning performance (
 = 0.019) between the two groups. Post scan lab assessment confidence scores also demonstrated a significant difference between how participants in each group scored their confidence levels (
 = 0.0260), especially in the ability to image calf veins.

This study suggests anatomical phantoms can be used to develop scanning skills and build confidence in ultrasound imaging of the lower extremity venous structures.

Ultrasound estimated fetal weight is increasingly being used in the monitoring of fetal growth. Differences between estimated fetal weight formulae, curves and measurement methods could lead to significant differences in results. The aim of this study was to investigate the potential impact of these differences on estimated fetal weight and its use in monitoring fetal growth, both by modelling and by analysis of ultrasound scan data.

Four estimated fetal weight curves were compared in their original form and also normalised to term weight. Estimated fetal weight was calculated from 50th centiles of widely used charts of abdominal and head circumference and femur length and plotted on a widely used estimated fetal weight curve. Fetal measurement data were used to assess the impact of fetal proportions on estimated fetal weight error and on growth trajectory when different estimated fetal weight formulae are used.

Estimated fetal weight curves differ significantly, but after normalisation there is closer agreement. Estimated fetal weight modelled using modern measurement methods differs from the widely used estimated fetal weight growth curve. Errors in estimated fetal weight are correlated with differences in fetal proportions and this can lead to significant changes in estimated fetal weight growth trajectory if different estimated fetal weight formulae are used.

Choice of measurement methods, estimated fetal weight formulae and growth curves have a significant effect on estimated fetal weight growth trajectories relative to normal ranges. It is important to understand these caveats when using estimated fetal weight to monitor fetal growth.
