Breast elastography early experiences
Abstracts Materials and Methods: All of eleven cases were confirmed either pathologically or clinically. We present 3 cases of scrotal neoplasms (immature teratoma, rapid growing and large seminoma, mixed germ cell tumor), 2 cases of infectious diseases (tuberculous epididymoorchitis, mumps epididymo-orchitis, 3 cases of other scrotal diseases (testicular torsion, testicular rupture, epididymal rupture), and 3 cases of penile diseases (penile fracture, paraffinoma, leiomyosarcoma). Results: Eleven cases of various diseases involving the male genitalia showed the variable ultrasonographic findings on grey scale and color Doppler ultrasonography. Clinical history is helpful in the diagnosis of some cases, such as mumps epididymitis, post-traumatic rupture of testis or epididymis, penile fracture or penile paraffinoma. Conclusion: We have to know the clinical history and specific ultrasonographic findings of various diseases of male genitalia for the exact diagnosis and differentiation.
Breast elastography early experiences Natalie Clements, Sandra O’Hara SKG Radiology, Bunbury, WA, Australia Introduction: Breast elastography improves the diagnostic performance of B mode ultrasound to characterise lesions. There are many methods to use shear wave values to assess breast lesions. The aim was to assess elastography of the breast to characterise breast lesions. Assessment of the breast lesion including histological profile, tumour grade and molecular subtype. Method : A prospective study, the patients were self selected into the study. The patients were routine visits to the ultrasound department and any lesions were assessed with measurements, colour doppler, vocal fremitis and elastography. The treatment pathway was not altered by this study. If they required a biopsy and were in agreeance for the pathology results and ultrasound results to be used, they were consented into the study. The lesions had the elastography value taken in radial and antiradial images. Results: The elastography values in mean and maximum showed a statistically significant result. Malignant lesions had higher quantitative values then benign breast lesions. The elastography ratio of lesion:fat was statistically higher in malignant lesions. The luminal results showed that ER- and PR-negative breast cancers have a higher elastography maximum than ER- and PR-positive breast cancer. HER-2 positive and triple-negative breast cancers have higher ratios compared to ER-positive breast cancers. Conclusion: The preliminary results show that elastography may be a complementary technique to conventional sonography to help characterise breast lesions. Take home message -Breast elastography improves the diagnostic performance of B mode ultrasound to characterise lesions including histological profile, tumour grade and molecular subtype.
The antenatal diagnosis of isolated sagittal craniosynostosis Sarah Constantine,1 Andreas Kiermeier,2 Peter Anderson3 1 Medical Imaging, The Women’s and Children’s Hospital, North Adelaide, SA, Australia, 2 Statistical Process Improvement Consulting and Training Pty Ltd, Gumeracha, SA, Australia, 3 Australian Craniofacial Unit, Women’s and Children’s Hospital, North Adelaide, SA, Australia Introduction: Isolated sagittal craniosynostosis is the most common premature sutural fusion, but is rarely diagnosed antenatally. There are now a number of reports in the literature describing delivery issues in infants later diagnosed with sagittal synostosis(1-6). The aim of this study
S87
was to investigate whether delivery issues are more common in children diagnosed with sagittal synostosis, and identify markers at antenatal ultrasound that could help diagnose the condition before birth. Methods: The antenatal ultrasound images of children born in South Australia and the Northern Territory after 1/1/2000 who have diagnosed with isolated sagittal synostosis were compared with antenatal imaging from normal infants without any craniofacial defects. The delivery details from the affected children were also compared to the population delivery data over an extended time period. Results: There was a statistically significantly higher rate of malpresentation and surgical delivery in the sagittal synostosis population. There no significant difference in the cephalic index between the 2 groups at mid trimester morphology scanning. The ultrasound scans showed progressive scaphocephaly during the second half of pregnancy in the affected children while the control population showed minimal change in head shape with a slight tendency towards brachycephaly. Conclusions: 1. Isolated sagittal synostosis typically begins in the second half of pregnancy, and is not detectable antenatally at the mid trimester morphology scan. 2. It is possible to diagnose sagittal synostosis in the third trimester by noting a progressive decrease in the fetal cephalic index, which should provoke 3D ultrasound scanning of the fetal skull to examine the sagittal suture. 3. There is a clear relationship between the presence of sagittal craniosynostosis and breech presentation at delivery in affected fetuses, with a marked increase in the rate surgical deliveries in this group of infants.
