“…Before launching the acquisition, the operator asks the patient to hold the breath in a neutral position without performing a Valsalva's maneuver for the few seconds needed for the acquisition [15]. Special applications in pediatric patients are discussed elsewhere [30,31,53].…”

We recently introduced a series of papers describing how to do certain techniques. This article is the first part of a review of shear wave elastography (SWE). It reports the principles and interpretation of the technique and describes how to optimize it. Normal values, pitfalls and artefacts for the examination of liver, breast. thyroid and salivary gland with shear wave elastography are presented. The manuscript provides specific tips for applying SWE as part of a diagnostic US examination.

“…There are also singular studies showing that LUS has similar accuracy to CT in diagnosing pneumonia complications such as pleural fluid, necrosis and abscess of lung parenchyma [29][30][31]. CEUS helps to evaluate consolidated lung parenchyma and identify necrotizing pneumonia and to describe pleural thickening and inflammation [32][33][34][35].…”

Ultrasound (US) is an ideal diagnostic tool for paediatric patients owning to its high spatial and temporal resolution, real-time imaging, and lack of ionizing radiation and bedside availability. In the current World Federation of Societies for Ultra-sound in Medicine and Biology (WFUMB) paper series so far (part I) the topic has been introduced and the technical require-ments explained. In the present paper the use of US in the lung in paediatric patients is analysed. Lung diseases including the interstitial syndrome, bacterial pneumonia and viral infections, CoViD findings, atelectasis, lung consolidation, bronchiolitis and congenital diseases of the respiratory system including congenital pulmonary airway malformation (CPAM) and sequester but also pneumothorax are discussed.

“…SWE has been widely used for many years to non-invasively estimate liver stiffness as a biomarker of liver fibrosis and there has been increasing interest in using SWE to identify patients with advanced fibrosis who might benefit from HCC surveillance (29)(30)(31)(32)(33)(34). The value of SWE to identify patients with chronic hepatitis at greater risk of HCC has been proven in replicating HCV, but has been insufficiently validated in patients who achieved sustained virologic response (SVR) after HCV eradication.…”

Effective treatments for early-stage hepatocellular carcinoma (HCC) have provided the rationale for HCC surveillance since detection of the disease at an early stage is associated with more favorable outcome. In a prospective multi-institutional diagnostic study, Park et al. (1) evaluated the added value of (perfluorobutane) contrast-enhanced ultrasound (CEUS) when combined with conventional B-mode ultrasound (US) as an HCC surveillance tool in participants with liver cirrhosis using a single arm, intraindividual comparison study design. The primary end points were the detection rate of early-stage HCC (Barcelona clinic liver cancer staging system stage 0 or A) and false-positive rate. Of the initially included 524 participants, 493 (94.1%) had liver cirrhosis related to the hepatitis B virus (HBV). Ten HCCs were confirmed in eight participants. The detection rate for early-stage HCC was not significantly improved by adding perfluorobutaneenhanced US to conventional B-mode US. However, the false-positive rate was significantly reduced.Some current clinical practice guidelines also recommend HCC surveillance in patients with chronic hepatitis C virus (HCV) infection and advanced liver fibrosis (stage F3) (2). Chronic HBV without cirrhosis is considered an indication for HCC surveillance if any of the following criteria is met (2-6): Active hepatitis [e.g., elevated serum alanine transaminase (ALT)] and/or high viral load (i.e., >100,000 copies/mL).  Family history of HCC [first degree relative, adjusted rate ratio (ARR) 2.4] (7).  Asian males over the age of 40 years, females over 50 years. The incidence of HCC in Asian patients with HBV is higher than in Caucasian patients (0.4 to 0.6 percent per year compared to less than 0.2 percent per year) (8,9). The incidence in male HBV carriers from Southeast Asia exceed 0.2% around the age of 40 years and is the basis for the recommendation that surveillance start in Asian men at age 40 years. The incidence in Asian women is lower, but it is not well defined.  Africans and African Americans (10,11).  Viral load >100,000 copies/mL (20,000 international units/mL) is a risk factor for disease progression and HCC in Asian patients (4-6). Also, surveillance is recommended for patients who are on effective antiviral treatment for chronic HBV infection and are HBsAg seropositive, although the risk of HCC appears to be decreased among these patients (2,3). In contrast, the incidence of HCC is low for treatmentnaïve patients with inactive hepatitis (long-term normal ALT and HBV DNA levels less than 2,000 international units/mL) (12,13). As a result, surveillance for such patients without cirrhosis and without an additional risk factor
