Sickle cell disease (SCD) is a common cause of cerebrovascular disease in childhood. Primary stroke prevention is effective using transcranial Doppler (TCD) scans to measure intracranial blood velocities, and regular blood transfusions or hydroxycarbamide when these are abnormal. Inadequate TCD scans occur when it is not possible to measure velocities in all the main arteries. We have investigated the prevalence and significance of this in a retrospective audit of 3915 TCD scans in 1191 children, performed between 2008 and 2015...

BACKGROUND: The invasive nature of the current methods for monitoring of intracranial pressure (ICP) has prevented their use in many clinical situations. Several attempts have been made to develop methods to monitor ICP non-invasively. The aim of this study is to assess the relationship between ultrasound-based non-invasive ICP (nICP) and invasive ICP measurement in neurocritical care patients. METHODS AND FINDINGS: This was a prospective, single-cohort observational study of patients admitted to a tertiary neurocritical care unit...

Endoscopic ultrasound (EUS) has evolved from a purely diagnostic to an interventional modality offering minimally invasive alternatives to surgical and radiologic interventions. This has led to a rapidly growing interest in EUS-guided vascular interventions. EUS-guided portal venous access is an emerging technique which opens a new arena for interventional vascular EUS. Portal vein can be accessed under EUS guidance with high precision and low risk of complications thus expanding its application for both benign and malignant conditions...

A Morel-Lavallee lesion (MLL) is a relatively rare condition that is caused by a traumatic shearing force. This force leads to a closed degloving injury of the subcutaneous tissue and fascia that creates a potential space that can fill with lymph, blood, and necrotic fat. The MLLs are traditionally seen after high impact trauma and typically located at the greater trochanter and pelvis, although recent reports have found them to be located at the knee, thigh, and lower leg. The MLLs typically present as swelling at the site of injury, which can be difficult to differentiate from several other diagnoses...

Fetal brain ultrasound remains as the mainstay for screening fetal intracranial anatomy. One of its main advantages is the availability of 3 dimensional and other ultrasound modalities for a better understanding of fetal neurodevelopment. Neurosonography is performed when findings, suggestive of an abnormality, are present on a screening ultrasound or if a high-risk situation of brain injury is present. This technique offers the use of complementary imaging planes, axial, coronal and sagittal, and the ability to image intracranial anatomy from the transabdominal and transvaginal approaches...

Pregnancy is frequently a women's first contact with the health care system and often her first pelvic ultrasound examination. This first sonogram can reveal previously unknown adnexal pathology. Approximately 4% of pregnant women will have an adnexal mass detected by sonography and 1% to 2% of these masses will persist. It is estimated that up to 7% of these persistent masses will be malignant. Sonography plays an important role in differentiating benign from malignant adnexal masses and physiological from pathologic masses and should be used judiciously to complement evaluation and help guide treatment...

Pregnancy failure is defined as a lack of sonographic evidence of current or expected viability. Technologic advances in ultrasound imaging continue to redefine diagnostic criteria of pregnancy failure or success. When evaluating a pregnancy, the first step is an assessment of maternal risk factors for failure. Imaging clues such as an empty gestational sac measuring ≥25 mm or an embryo ≥7 mm without cardiac activity are reliable signs of pregnancy failure, whereas embryonic growth <1 mm/d is not. Combinations of sonographic findings can be used for a more accurate prediction of pregnancy success or failure...

Quality assurance (QA) and safety are important components of obstetric imaging. Quality involves accreditation of the imaging unit as well as equipment inspection for function and image quality. The personnel working in the unit must demonstrate qualifications to perform, evaluate, and interpret the studies. Standardizing the required elements of the examination helps assure that a quality examination has been performed. QA and safety as well as physician requirements and equipment QA programs in ultrasound, computed tomography, and magnetic resonance will be discussed with an in depth look at ultrasound due to its more frequent use in pregnancy...

Endometriosis is a condition with variable location, size, and lesion composition which poses a diagnostic imaging challenge for the practicing gynecologist. Transvaginal ultrasound and magnetic resonance imaging are the most frequent imaging techniques used for its evaluation, but transvaginal ultrasound should be the first-line approach, as it is often sufficient, followed by modified ultrasound techniques. Magnetic resonance imaging should be considered when a diagnosis has not been achieved by sonographic means or when the renal system needs to be concurrently evaluated...

Pancreatic cancer (PC), one of the most lethal malignancies, accounts for 8% to 10% of digestive system cancers, and the incidence is increasing. Surgery, chemotherapy, and radiotherapy have been the main treatment methods but are not very effective. Cryosurgery was first used in 1984 for treatment of locally advanced PC and has since become a considerable treatment for most cases of unresectable PC. During the past decade, cryosurgery has been applied in some hospitals in China, and the newly developed technique of computed tomography- and/or ultrasound-guided percutaneous cryosurgery has shown better results than chemotherapy in cases of unresectable locally advanced PC, with the 1-year survival rate reported to be more than 50%...

We report on a girl diagnosed prenatally with agenesis of the corpus callosum (ACC) on fetal ultrasound and MRI. On postnatal follow-up she was noted to have developmental delay, facial dysmorphism, autism spectrum disorder, and posterior polymorphous corneal dystrophy (PPD). Array-comparative genomic hybridization analysis (Array-CGH) showed a 2.05 Mb de novo interstitial deletion at 10p11.23p11.22. The deleted region overlaps 1 OMIM Morbid Map gene, ZEB1 (the zinc finger E-box binding homeobox transcription factor 1), previously associated with posterior polymorphous corneal dystrophy type 3 (PPCD3)...

Loose peritoneal cysts - unexpected finding at laparoscopic surgery for suspected extrauterine pregnancy, a case report A 29 year old woman was admitted to inpatient care in the 7th week of pregnancy due to three previous episodes of abdominal pain. At admission a suspected pseudogestational sac and 2 × 3 centimetres of fluid in the cul-de-sac was noted at vaginal ultrasound examination. After two days she again developed pain and a laparoscopy was performed due to suspected extrauterine pregnancy. Instead, three clusters of thin-walled, clear cysts was found lying loose in the cul-de-sac...
