Abstract
Over the past two decades, contrast-enhanced ultrasound (CEUS) has been established as a method complementary to B-mode ultrasound and color Doppler sonography for diagnosing vascular liver pathologies and interventions.The objective of this review is to elucidate the application of CEUS in diagnosing vascular pathologies and interventional procedures.Considering the limitations of ultrasound, CEUS presents a similar alternative to other imaging modalities, such as computed tomography and magnetic resonance imaging, for evaluating vascular pathologies, guiding interventions, identifying complications, and assessing outcomes post intervention. Due to its widespread availability and the absence of radiation exposure, CEUS should be employed as a primary modality. · CEUS plays an important role in the detection of vascular liver pathologies.. · CEUS is helpful in characterizing vascular pathologies.. · CEUS is helpful in guiding interventions and identifying complications..

Abstract
PURPOSE To evaluate the diagnostic yield of contrast-enhanced ultrasound (CEUS)-guided biopsy of retroperitoneal masses (RMs). MATERIALS AND METHODS Between 2006 and 2023, 87 patients presented at our US center for biopsy of an RM. In all biopsies, CEUS was performed prior to the intervention. The technical success rate of biopsy, the presence of diagnostic tissue in solid tumor biopsy samples, the accuracy of the biopsy and the occurrence of post-interventional complications were evaluated. RESULTS A US-guided biopsy could be conducted in 84/87 cases (96.6%). In 3/87 cases (3.4%), US-guided biopsy was impossible because the planned needle path was obstructed by vital structures. Of 84 lesions, 80 (95.2%) were solid lesions, and 4 (4.8%) were lesions containing fluid. In all solid tumors, 80/80 (100%), diagnostic vital tissue was successfully obtained. CEUS-guided biopsy showed a sensitivity of 93.2%, a specificity of 100%, a positive predictive value of 100%, a negative predictive value of 72.2%, and a diagnostic accuracy of 94.2% for the differentiation between malignant and benign RMs. In one of the 84 cases (1.2%), there was a complication of postinterventional abdominal pain. CONCLUSION Percutaneous CEUS-guided biopsy is a safe procedure with a high diagnostic yield and a low complication rate.

Abstract
Aim of the study Spontaneous splenic rupture is a serious complication of pathologically altered spleen tissue, associated with a high mortality rate. Case description We describe a spontaneous splenic rupture in a patient with acute lymphoblastic leukemia undergoing chemotherapy. Ultrasound revealed splenomegaly, and diffuse splenic acute lymphoblastic leukemia-infiltration was suspected. In addition, only color Doppler sonography and contrast-enhanced ultrasound diagnosed splenic vascular ectasias with a venous-flow-profile. During therapy, short-term sonographic follow-up examinations were able to reveal an increase in the size of venous ectasias and the associated increased risk of spontaneous splenic rupture. Based on these sonographic findings, immediate surgical splenectomy was performed in the spontaneous splenic rupture case and the patient survived. Conclusions Ultrasound is an important diagnostic method in patients with newly diagnosed malignant hematological diseases to detect disease-related splenic pathologies. Short-term follow-up examinations of splenic vascular pathologies can detect size progression and a potential risk of spontaneous splenic rupture with life-threatening bleeding.

Abstract
Lung ultrasound is a well-established diagnostic approach used in detecting pathological changes near the pleura of the lung. At the acoustic boundary of the lung surface, it is necessary to differentiate between the primary visualization of pleural parenchymal pathologies and the appearance of secondary artifacts when sound waves enter the lung or are reflected at the visceral pleura. The aims of this pictorial essay are to demonstrate the sonographic patterns of various pleural interface artifacts and to illustrate the limitations and pitfalls of the use of ultrasound findings in diagnosing any underlying pathology.

Abstract
BACKGROUND The use of urinary sodium to guide diuretics in acute heart failure is recommended by experts and the most recent European Society of Cardiology guidelines. However, there are limited data to support this recommendation. The ENACT-HF study (Efficacy of a Standardized Diuretic Protocol in Acute Heart Failure) investigated the feasibility and efficacy of a standardized natriuresis-guided diuretic protocol in patients with acute heart failure and signs of volume overload. METHODS ENACT-HF was an international, multicenter, open-label, pragmatic, 2-phase study, comparing the current standard of care of each center with a standardized diuretic protocol, including urinary sodium to guide therapy. The primary end point was natriuresis after 1 day. Secondary end points included cumulative natriuresis and diuresis after 2 days of treatment, length of stay, and in-hospital mortality. All end points were adjusted for baseline differences between both treatment arms. RESULTS Four hundred one patients from 29 centers in 18 countries worldwide were included in the study. The natriuresis after 1 day was significantly higher in the protocol arm compared with the standard of care arm (282 versus 174 mmol; adjusted mean ratio, 1.64; P<0.001). After 2 days, the natriuresis remained higher in the protocol arm (538 versus 365 mmol; adjusted mean ratio, 1.52; P<0.001), with a significantly higher diuresis (5776 versus 4381 mL; adjusted mean ratio, 1.33; P<0.001). The protocol arm had a shorter length of stay (5.8 versus 7.0 days; adjusted mean ratio, 0.87; P=0.036). In-hospital mortality was low and did not significantly differ between the 2 arms (1.4% versus 2.0%; P=0.852). CONCLUSIONS A standardized natriuresis-guided diuretic protocol to guide decongestion in acute heart failure was feasible, safe, and resulted in higher natriuresis and diuresis, as well as a shorter length of stay.

Abstract
BACKGROUND Stress hyperglycaemia (SH) and acute kidney injury (AKI) occur frequently in critically ill patients, and particularly non-diabetics are associated with adverse outcome. Data is scarce on the effect of SH on AKI. We assessed whether SH (i) preceded AKI, (ii) was a risk factor of subsequent AKI, and (iii) how SH and tubular injury interacted in AKI development in critically ill, non-diabetics. METHODS Case-control study of 82 patients each with and without SH matched by propensity score for multiple demographic characteristics. AKI was defined by KDIGO criteria, SH either as blood glucose (BG) > 140 mg/dl (BG140), > 200 mg/dl (BG200), or stress hyperglycemia rate (SHR) ≥ 1.47 (SHR1.47) as measured 2 days before AKI. Urinary cystatin C and neutrophil gelatinase-associated lipocalin (NGAL) indicated tubular injury. RESULTS In AKI, SH rates were frequent using all 3 definitions applied, but highest when BG140 was applied. SH by all 3 definitions was consistently associated with AKI. This was independent of established risk factors of AKI such as sepsis and shock. Increments of BG, urinary NGAL or cystatin C, and its products, were independently associated with the likelihood of subsequent AKI, demonstrating their reciprocal potentiating effects on AKI development. CONCLUSIONS SH is frequent in critically ill, non-diabetics with AKI. SH was identified as an independent risk factor of AKI. Higher BG combined with tubular injury may potentiate their adverse effects on AKI.

Abstract
PURPOSE To evaluate B-mode ultrasound (B-US) and contrast-enhanced ultrasound (CEUS) patterns of focal splenic incidentalomas (FSIs), and to correlate ultrasound patterns with benignity and malignancy via histologic examination and/or the clinical course. MATERIALS AND METHODS Between 2004 and 2021, 139 consecutive patients with an FSI detected by B-US were investigated additionally with CEUS. On CEUS, the arterial enhancement (AE) of the FSI (hyperenhancement, isoenhancement, hypoenhancement, and absent enhancement) was analyzed. Subsequently, the malignancy rate according to different B-US echo patterns and CEUS perfusion patterns was determined. RESULTS The final diagnosis of FSI was malignant in 9/139 (6.5%) and benign in 130/139 (93.5%) cases. The hypoechoic and hyperechoic lesions on B-US with arterial hyperenhancement on CEUS and the echogenic cystic or complex lesions on B-US with predominantly absent enhancement on CEUS were benign in 54/54 (100%) cases. 6/37 (16.2%) hypoechoic lesions on B-US with arterial hypo-/isoenhancement on CEUS and 3/48 (6.3%) of hyperechoic lesions on B-US with an arterial hypo-/isoenhancement on CEUS were malignant. CONCLUSION Based on these results, FSIs reveal different malignancy rates depending on the B-US und CEUS patterns, and classification according to these B-US and CEUS patterns may be helpful in further evaluation of an FSI.

Abstract
BACKGROUND Splenic tumors are rare and can pose a differential diagnostic challenge, especially as an incidental imaging finding. Due to a lack of large scale biopsy studies the available literature is limited with respect to clear imaging criteria for dignity. OBJECTIVE The present work is intended to show the chances of a targeted elicitation of the medical history as well as the possibilities and limitations of multimodal sonography in order to achieve the correct diagnosis of a splenic lesion using simple and gentle methods. MATERIAL AND METHODS Selective literature search and clinical case studies. RESULTS In the differential diagnostics of focal splenic lesions, information about pre-existing hemato-oncological or inflammatory rheumatological diseases is essential in order to correctly classify incidental findings in particular. In addition to B‑mode ultrasound (B-US) and color-coded Doppler ultrasound (CD-US), contrast-enhanced ultrasound (CEUS) in particular provides crucial differential diagnostic information. While hyperechoic foci in B‑US or arterially hypervascularized splenic foci in CD-US/CEUS are usually benign, hypoechoic and arterially hypoperfused foci in CD-US/CEUS must be further clarified. Although the ultrasound-guided biopsy of the spleen has a higher risk of bleeding than a liver biopsy, it is still the gentlest and most effective method for achieving the histological clarification of splenic lesions when the indications are correct. CONCLUSION Through the combination of the medical history and multimodal ultrasound methods, if necessary supplemented by an ultrasound-guided biopsy, focal splenic lesions can be successfully classified in most cases with a direct impact on further clinical procedures.

Abstract
PURPOSE To assess splenic involvement using B-mode ultrasound (US) and contrast-enhanced ultrasound (CEUS) compared with standard imaging with contrast-enhanced computerized tomography (CT) / 18-fluorodeoxyglucose positron-emission tomography (PET-CT) in patients with Hodgkin lymphoma. MATERIALS AND METHODS Imaging data from 112 patients from 12/2003 to 10/2022 with histologically confirmed Hodgkin lymphoma during staging or relapse were analyzed for splenic lymphoma involvement. In all patients, standard imaging (CT/PET-CT), along with B-mode US and CEUS examinations, was performed. Evidence of focal splenic lesions (FSLs) found by imaging procedures was suggestive of splenic involvement. Follow-up imaging was performed in each patient after treatment, and treatment response indicated definitive splenic involvement. RESULTS 40 patients (35.7%) were identified by imaging modalities as having splenic involvement, which was confirmed by response during follow-up. Standard CT/PET-CT imaging detected splenic involvement in 36/112 patients (32.1%). FSLs were detected with B-mode US in 38 patients (33.9%) and CEUS in 36 patients (32.1%). The sensitivity of standard imaging, B-mode US, and CEUS was 90%, 95%, and 90%, respectively. CONCLUSION B-mode US examination is a diagnostic method used in addition to standard imaging for the detection of splenic involvement in Hodgkin lymphoma. CEUS does not provide additional benefit compared to B-mode US and the standard reference procedure.

Abstract
PURPOSE Nontraumatic focal splenic lesions (FSL) are rare, and the need for tissue diagnosis must be weighed against the very high risk of bleeding after a splenic biopsy. The aim of this study was to explore the feasibility and diagnostic potential of acoustic radiation force impulse (ARFI) elastography as a noninvasive method for different benign and malignant FSLs. No human studies on the elastographic characteristics of FSL exist. METHODS This was a retrospective analysis of 34 patients with FSLs, who underwent abdominal B-mode ultrasound (B-US), contrast-enhanced ultrasound (CEUS), and standardized ARFI examinations between October 2021 and December 2022 at our university hospital. The inclusion criteria were: (i) FSL size ≥ 1 cm; (ii) 10 valid ARFI measurements of the FSL, as well as of the normal splenic parenchyma (NSP) as an in vivo reference; and (iii) diagnostic confirmation of FSL etiology based on histological examination (8/34; 23.5%) or clinical evaluation, which included a clinical and sonographic follow-up (FU), CEUS morphology, and/or morphology on cross-sectional imaging (26/34; 76.5%). CEUS was performed on all patients and the FSLs were classified according to the current guidelines; cross-sectional imaging was available for 29/34 (85.3%). The mean FU duration was 25.8 ± 30.5 months. The mean ARFI velocity (MAV) of the FSL (MAVL), the NSP (MAVP), and the ratio of the MAVL to the MAVP (MAVL/P) were calculated and compared. RESULTS Of the 34 FSLs, 13 (38.2%) were malignant (mFSL) and 21 (61.8%) were benign (bFSL). The MAVL of all 34 FSLs (2.74 ± 0.71 m/s) was lower than the MAVP (3.20 ± 0.59 m/s), p = 0.009, with a mean MAVL/P ratio of 0.90 ± 0.34. No significant differences in the MAVL were observed between the mFSL (2.66 ± 0.67 m/s) and bFSL (2.79 ± 0.75 m/s). There were also no significant differences between the MAVP in patients with mFSL (3.24 ± 0.68 m/s) as compared to that in the patients with bFSL (3.18 ± 0.55 m/s). Likewise, the MAV L/P ratio did not differ between the mFSL (0.90 ± 0.41 m/s) and bFSL (0.90 ± 0.30 m/s) groups. CONCLUSION ARFI elastography is feasible in evaluating the stiffness of FSLs. The lesions' stiffness was lower than that of the NSP, regardless of the FSL etiology. However, differentiation between benign and malignant FSL with the help of this elastographic method does not appear possible. Larger prospective studies are needed to validate these findings.

Abstract
Due to their often peripheral pleural-based location, pneumonias can be visualised by B-mode ultrasound. Therefore, sonography can be used as an alternative imaging modality to chest X-ray in suspected cases of pneumonia. Depending on the clinical background of the patient, and various underlying pathological mechanisms, a heterogeneous pattern of pneumonia is seen in both B-mode lung ultrasound and contrast-enhanced ultrasound. Here, we describe the spectrum of sonographic manifestations of pneumonic/inflammatory consolidation on B-mode lung ultrasound and contrast-enhanced ultrasound.

Abstract
Aim of the study Pulmonary cystic echinococcosis is a parasitic infection transmitted by dogs and occurring in livestock-raising areas. It is included among the neglected tropical diseases, according to the World Health Organization. Imaging plays a pivotal role in the diagnosis of this disease. While cross-sectional imaging modalities such as computed tomography and magnetic resonance imaging are preferred, lung ultrasound may be another feasible technique. Case description We report a case of pulmonary cystic echinococcosis in a 26-year-old woman who was examined by contrast-enhanced ultrasound, which showed marked annular enhancement around the hydatid cyst, mimicking a superinfected cyst. Conclusions Contrast-enhanced ultrasound examination in pulmonary cystic echinococcosis should be studied in a larger population to determine the value of additional contrast administration. In the present case report, no superinfected echinococcal cyst was seen despite marked annular contrast enhancement.

Abstract
Aim of the study Inflammatory pseudotumor is a rare benign tumor that can occur at various body sites. Due to its rare occurrence and histological variety radiological data is heterogeneous and limited. Case description We present a case of a 71-year-old man with inflammatory pseudotumor of the omentum. Contrast-enhanced ultrasound perfusion pattern showed homogeneous, isoechoic enhancement in the arterial phase with a washout phenomenon in the parenchymal phase, mimicking a peritoneal carcinomatosis. Conclusions Inflammatory pseudotumor represents a rare, but important benign differential diagnostic option when considering a malignant disorder. Contrast-enhanced ultrasound is helpful in identifying vital tissue for a targeted biopsy for subsequent histological examination that is essential for the exclusion of malignancy.

Abstract
INTRODUCTION To describe the value of contrast-enhanced ultrasound (CEUS) for the differentiation of malignant from benign parietal pleural lesions (PPLs). MATERIALS AND METHODS From November 2005 to June 2019, 63 patients with histologically/cytologically confirmed PPLs were investigated by CEUS. On CEUS, the extent of enhancement (EE; marked or reduced/absent) and the homogeneity of enhancement (HE; homogeneous or inhomogeneous) were analyzed retrospectively. RESULTS In total, 24/63 lesions were benign, and 39/63 lesions were malignant. On CEUS, 11/24 benign and 36/39 malignant lesions showed a marked enhancement. A marked enhancement was significantly more frequently associated with malignancy compared with benign lesions (p < 0.001). In five cases, due to the absence of enhancement, it was not possible to determine the HE. In the remaining cases, 9/20 benign and 19/38 malignant lesions showed an inhomogeneous enhancement (p = 0.79). CONCLUSION On CEUS, marked enhancement was significantly more frequently associated with malignant compared with benign lesions. However, some benign lesions, such as chronic inflammatory processes, may also show a marked enhancement. Therefore, the interpretation of perfusion patterns in these lesions must always take into account the clinical background of the patient.

Abstract
Aims Although acute heart failure (AHF) with volume overload is treated with loop diuretics, their dosing and type of administration are mainly based upon expert opinion. A recent position paper from the Heart Failure Association (HFA) proposed a step‐wise pharmacologic diuretic strategy to increase the diuretic response and to achieve rapid decongestion. However, no study has evaluated this protocol prospectively. Methods and results The Efficacy of a Standardized Diuretic Protocol in Acute Heart Failure (ENACT‐HF) study is an international, multicentre, non‐randomized, open‐label, pragmatic study in AHF patients on chronic loop diuretic therapy, admitted to the hospital for intravenous loop diuretic therapy, aiming to enrol 500 patients. Inclusion criteria are as follows: at least one sign of volume overload (oedema, ascites, or pleural effusion), use ≥ 40 mg of furosemide or equivalent for >1 month, and a BNP > 250 ng/L or an N‐terminal pro‐B‐type natriuretic peptide > 1000 pg/L. The study is designed in two sequential phases. During Phase 1, all centres will treat consecutive patients according to the local standard of care. In the Phase 2 of the study, all centres will implement a standardized diuretic protocol in the next cohort of consecutive patients. The protocol is based upon the recently published HFA algorithm on diuretic use and starts with intravenous administration of two times the oral home dose. It includes early assessment of diuretic response with a spot urinary sodium measurement after 2 h and urine output after 6 h. Diuretics will be tailored further based upon these measurements. The study is powered for its primary endpoint of natriuresis after 1 day and will be able to detect a 15% difference with 80% power. Secondary endpoints are natriuresis and diuresis after 2 days, change in congestion score, change in weight, in‐hospital mortality, and length of hospitalization. Conclusions The ENACT‐HF study will investigate whether a step‐wise diuretic approach, based upon early assessment of urinary sodium and urine output as proposed by the HFA, is feasible and able to improve decongestion in AHF with volume overload.

Abstract
PURPOSE To describe the vascularization of peripheral lung carcinoma in CEUS and to compare with B-mode ultrasound (US) and clinical data. MATERIALS AND METHODS From April 2004 until September 2015, n = 89 patients with peripheral lung carcinoma were investigated by B-mode US and CEUS. The extent (EE: hypoechoic, hyperechoic), homogeneity (HE: homogeneous, inhomogeneous) and time of enhancement (TE) have been defined. Early pulmonary-arterial enhancement (PA) before contrast floating to the thoracic wall was differentiated from simultaneous or delayed bronchial-arterial enhancement (BA). CEUS parameters were compared by B-mode US and histology. RESULTS n = 25 patients had early PA enhancement (TE: 8 ± 3.7 s), and n = 64 (72 %) had simultaneous/delayed BA enhancement (TE: 17.6 ± 6.2 s) (p < 0.001). PA enhancement (EE/HE) was hyperechoic (n = 11/25), homogeneous (n = 11/25) and showed an air bronchogram more often (n = 11/17, p < 0.001). BA enhancement (EE/HE) was frequently hypoechoic (n = 34/64) and inhomogeneous (n = 54/64). BA enhancement was associated with necrosis (n = 36/42, p = 0.009). PA and BA enhancement distributed to different histologies: n = 42 adenocarcinomas (18 PA, 24 BA), n = 30 squamous cell carcinomas (4 PA, 26 BA), n = 13 other types of NSCLC (3 PA, 10 BA), and n = 4 SCLC (0 PA, 4 BA) (p = 0.016). CONCLUSION The vascularization of peripheral lung carcinomas is heterogeneous and is influenced by histology. In this study, lung carcinomas are predominantly supplied by bronchial arteries, whereas a part of adenocarcinomas and non-adenocarcinomas show PA enhancement.
