Although uncommon, abnormalities of the placenta are important to recognise owing to the potential for both maternal and fetal morbidity and mortality. The placenta is often overlooked in the routine evaluation of a normal gestation, receiving attention only when an abnormality is detected. During the formal scan to confirm a fetal death, the information gathering process to elucidate a possible cause of death begins, yet, even in this instance, the placenta is seldom examined. We aim to draw attention to the importance of placental assessment by presenting a case of a stillbirth where the answer to the cause of death lay in the placenta...

Kelly Collins, Alka Kothari
Ectopic pregnancy that implants within the scar tissue of a previous caesarean scar is a situation that is seldom encountered and is almost invariably incompatible with a successful pregnancy. Caesarean scar ectopic pregnancies are fraught with life threatening complications such as scar rupture, significant haemorrhage, disseminated intravascular coagulation and the need for emergency life saving hysterectomy. The clinical diagnosis can be elusive, particularly in the early stages; therefore clinicians should be familiar with the condition's sonographic hallmarks...

Background: Lung ultrasound is frequently used to identify pulmonary oedema, using the 'B line' artefact. A small study in 2011 suggested that novice sonologists had a potential diagnostic accuracy of 85%, when performing the test without reference to other patient information. Aim: We aimed to test the overall diagnostic accuracy of novice clinician sonologists incorporating the 2011 protocol into routine assessment of the patient. Method: A prospective convenience sample of breathless older patients presenting to ED received an 8-view lung scan early in management...

REVIEW
Khai Gene Leong, Peter Coombs, John Kanellis
One of the principal roles of a nephrologist is to closely monitor renal transplant allograft function and promptly evaluate any dysfunction. Renal transplant sonography has a major role in this assessment process given its ability to easily define renal transplant anatomy and surrounding structures. Abnormalities can be extrarenal or involve vascular, parenchymal and urological components of the graft and these can acutely or chronically influence graft function and survival. Procedural guidance as is required during allograft biopsy, as well as routine surveillance and screening for post transplant complications such as malignancy are also important applications of ultrasound in the management of renal transplant recipients...

Paul Brooks
Complete heart block (CHB) is a potentially fatal condition occurring in approximately 1:10000 fetuses. Whilst it is well recognised that maternal anti-Ro and La antibodies are associated with fetal CHB, there are multiple other manifestations of fetal exposure to these autoantibodies which are not widely appreciated and rarely diagnosed. The importance of identifying affected fetuses lies in the significantly increased risk of recurrence in future pregnancies, and the potential for treatments which may modify this risk...

Introduction: The appropriate ultrasound technique to assess the maternal cervical length in women at low risk of preterm birth is yet to be established. This study aimed to determine the accuracy of different ultrasound approaches for measuring the maternal cervix in patients between 17 and 22 weeks gestation. Methods: The prospective study recruited 50 patients who were at a low risk of preterm birth. All measurements were acquired by one operator who was blind to the measurements being acquired in all approaches...

Brooke Osborne, Nayana Parange, Kerry Thoirs
Introduction: The benefits of the use of ultrasound technology for point of care obstetric health evaluation have led to increased focus on training programs for physicians wanting to develop skills in this area. Simulation, in a variety of formats, has always played a role in medical and health training, with proven benefits. This systematic review determines the level of evidence available to support the use of high fidelity ultrasound simulators in the training of obstetric ultrasound scanning skills to health professionals...

Luke Porra, Hans Swan, Chien Ho
Introduction: Acoustic Radiation Force Impulse (ARFI) Quantification measures shear wave velocities (SWVs) within the liver. It is a reliable method for predicting the severity of liver fibrosis and has the potential to assess fibrosis in any part of the liver, but previous research has found ARFI quantification in the right lobe more accurate than in the left lobe. A lack of standardised applied transducer force when performing ARFI quantification in the left lobe of the liver may account for some of this inaccuracy...

Infection control and prevention is critical to delivering safe and high-quality care to patients undergoing sonographic procedures. In Australia comprehensive standards for reprocessing of ultrasound probes are based on the AS/NZS, TGA and ASUM recommendations. These standards align with the US Centers for Disease Control and Prevention recommendations. However compliance to these guidelines is not ideal and there exists an unmet need for refinement of the guidelines relating to specific factors in clinical sonography...

Background: Carpal tunnel syndrome (CTS) is a sporadic event with compression of the median nerve (MN). Persistent median artery (PMA) thrombosis is an exceptionally rare cause of CTS. Case report: 38-year-old male presented with acute on subacute right wrist pain with positive Tinel's sign. An ultrasound and computed angiography study confirmed a PMA with thrombosis. The patient was treated with intravenous heparin then discharged home on enoxaparin and warfarin crossover. Discussion: PMA can lead to CTS by compression from the adjacent median nerve...

Colin A Walsh
It is well established that the death of one fetus in a monochorionic twin pregnancy places the surviving twin at significant risk for neuro-developmental delay or death. Although the early 1st trimester "vanishing twin" has not traditionally been considered a major risk, the precise gestational threshold beyond which a surviving twin is at risk remains uncertain. Most experts recommend serial ultrasounds and fetal MRI in the survivor, to look for evidence of ischaemic brain injury. We present a case of early monochorionic twin demise at 14-16 weeks, with evolving ventriculomegaly and ischaemic changes on fetal MRI in the co-twin, leading to termination of pregnancy at 28 weeks...

Introduction: Visual search is a task that humans perform in everyday life. Whether it involves looking for a pen on a desk or a mass in a mammogram, the cognitive and perceptual processes that underpin these tasks are identical. Radiologists are experts in visual search of medical images and studies on their visual search behaviours have revealed some interesting findings with regard to diagnostic errors. In Australia, within the modality of ultrasound, sonographers perform the diagnostic scan, select images and present to the radiologist for reporting...

Introduction: The predictive value of spiral artery flow Doppler measurements of a subsequent early miscarriage in first trimester pregnancy is explored here. Objective: The aim of this study is to determine uterine and spiral artery blood flow changes in first trimester subsequent miscarriages and correlate within the mechanisms of the Doppler indicies. Study design: The uterine artery and spiral artery pulsatility and resistance indexes, systolic and diastolic ratios, acceleration times, and blood flow of both the right and left uterine arteries were obtained by trans vaginal color Doppler ultrasonography in consecutive viable pregnancies between 5 and 12 gestational week...
