Purpose: To describe and characterize the accuracy and benefit of a technique for performing ultrasound-guided needle placement for iliopsoas peritendon or bursa injections as an alternative method to fluoroscopic guidance.
Materials and methods: Patients with a history of total hip arthroplasty who were referred by their orthopedic surgeon for iliopsoas peritendon or bursa corticosteroid injection for iliopsoas impingement syndrome between June 2017 and December 2019 were eligible for inclusion. Of these patients, 19 received a total of 26 ultrasound-guided needle placement followed by confirmatory fluoroscopic guidance prior to injection. Pre-injection and post-injection VAS scores were collected to monitor pain. Additionally, the patients were followed for 6 months via chart review after their injection to assess for complications, need for repeat injections, and progression to surgical intervention. The accuracy of a longitudinal in-plane distal to proximal approach to ultrasound guided needle placement was then evaluated.
Results: Ultrasound guided needle placement using a longitudinal in-plane distal to proximal approach demonstrated spread of contrast material in the intended anatomic location with fluoroscopic confirmation in patients who underwent iliopsoas peritendon or bursa injection post total hip arthroplasty.
Conclusion: Ultrasound guided needle placement using a longitudinal in-plane distal to proximal approach can be an effective alternative technique for diagnostic or therapeutic iliopsoas peritendon injection in patients with total hip arthroplasty.

Purpose: To evaluate the role of multiparametric ultrasound (mpUS) in the characterization of focal breast lesions (FBLs).
Methods: This prospective study enrolled patients undergoing multiparametric breast ultrasound for FBLs. An experienced breast radiologist evaluated the following ultrasound features: US BI-RADS category, vascularization pattern (internal, vessels in rim and combined) and presence of penetrating vessels with each Doppler method (Color-Doppler, Power-Doppler, Microvascular imaging), strain ratio (SR) and Tsukuba score (TS) with Strain Elastography (SE), Emax, Emean, Emin and Eratio with 2D-shear wave elastography (2D-SWE). Core biopsy for all BI-RADS 4-5 FBLs and 24-month follow-up for all BI-RADS 2-3 FBLs were considered for standard of reference. The diagnostic performance was assessed with the area under curve (AUCs) and cut-off values were determined according to the Youden's index.
Results: A total of 139 FBLs were included with 75/139 (53.9%) benign and 64/139 (46.1%) malignant FBLs. Internal vascularization patterns (p < 0.001), penetrating vessels (p < 0.001), TS 4-5 (p < 0.001) and all 2D-SWE parameters (p < 0.001) were significantly different between benign and malignant FBLs. The BI-RADS score provided an AUC of 0.876 (95% CI 0.810-0.926) for the diagnosis of malignant FBLs. Among the 2D-SWE measurements, an excellent diagnostic performance was observed for Emax with an AUC of 0.915 (95% CI 0.856-0.956) and Emean of 0.908 (95% CI 0.847-0.951). Optimal cutoff for the diagnosis of malignant FBLs were US BI-RADS > 3, Strain Ratio > 2.52, Tsukuba Score > 3, Emax > 82.6 kPa, Emean > 66.0 kPa, Emin > 54.4 kPa and Eratio > 330.8. Multiparametric ultrasound, particularly SWE, can improve specificity in the characterization of FBLs.

Gestational trophoblastic disease (GTD) comprises hydatidiform mole, invasive mole, epithelioid trophoblastic tumor, placental site trophoblastic tumor, and choriocarcinoma. Ectopic molar gestation (EMG) is exceedingly rare with similar malignant potential like that of an intrauterine molar pregnancy. We report an uncommon case of EMG diagnosed by ultrasonography (USG) with a brief literature review. A 36-year-multipara presented at 8-weeks gestational age with severe abdominal pain and spotting. She underwent a spontaneous abortion 4 months back. Current transabdominal USG revealed a large right adnexal hydatidiform mole with moderate hemoperitoneum. Right ovary could not be discerned separately. Emergency laparotomy with hysterectomy and right adnexal clearance was done. Histopathology showed complete ectopic hydatidiform mole. USG remains the modality of choice for initial assessment of suspected GTD and it allows reliable evaluation of residual or recurrent disease. This report emphasizes the role of USG in the diagnosis of EMG and also, the importance of including EMG in the differential diagnosis of suspected ectopic pregnancy.

Intracerebral hemorrhage (ICH) is a common neurosurgical emergency that is associated with high morbidity and mortality. Minimally invasive or endoscopic hematoma evacuation has emerged in recent years as a viable alternative to conventional large craniotomies. However, accurate trajectory planning and placement of the tubular retractor remains a challenge. We describe a novel technique for handheld portable ultrasound-guided minimally invasive endoscopic evacuation of supratentorial hematomas. A 64-year-old male diagnosed right hematoma (48.5 mL) at the basal ganglia was treated with emergent ultrasound-guided endoscopic transtubular evacuation through a small craniotomy. Ultrasound-guidance facilitated optimal placement of the tubular retractor into the long axis of the hematoma, and allowed for near-total evacuation, reducing iatrogenic tissue damage by mitigating the need for wanding or repositioning of the retractor. The emergence of a new generation of small portable phased array ultrasound probes with improved resolution and clarity has broadened ultrasound's clinical applications.

Aims: Lung ultrasound (LUS) is increasingly used in Internal Medicine to complement medical examination, documenting pleural and lung conditions. This study aimed to compare the accuracy of handheld ultrasound device (HHUSD) with high-end ultrasound device (HEUSD) in patients with heart failure or pneumonia, also including the assessment of costs and time-savings.
Methods: In this observational study 72 patients (aged ≥ 18) admitted to Internal Medicine Unit for heart failure or pneumonia underwent LUS plus evaluation of inferior cava vein (ICV) when indicated, using both HHUSD and HEUSD. Each evaluation, independently performed by 2 different experienced operators, included B-lines number, pleural effusion, lung consolidations, ICV ectasia and its respiratory excursions.
Results: Concordance between HHUSD and HEUSD findings was 79.3% ± 17.7 (mean ± SD) for B-lines, 88.6% for pleural effusion, 82.3% for consolidations and 88.7% and 84.9% for ICV ectasia and its respiratory excursions respectively. BMI didn't significantly influence concordance between the two methods. Moreover, examination time (as mean ± SD) was shorter with HHUSD (8 ± 1.5 min) compared to HEUSD (10 ± 2.5 min).
Conclusions: HHUSD demonstrated high accuracy in detecting B-lines, pleural effusions, lung consolidations and ICV evaluation when compared to HEUSD. Thus, HHUSD, not only is characterized by accessibility, portability, and easy handling due to its small size, but it also offers advantages in terms of saving costs and time, ultimately contributing to faster patient assessment compared to HEUSD.

Isolated spontaneous tears in the non-insertional portion of the iliopsoas tendon without any underlying injury are uncommon, especially among elderly individuals. We describe the case of an 88-year-old man who experienced right groin pain caused by a spontaneous non-insertional tear in the iliopsoas tendon identified through ultrasound and confirmed via MRI. Ultrasound revealed hypoechogenicity in the non-insertional portion of the iliopsoas tendon, leading to quick identification and conservative treatment and resulting in positive functional outcomes. This case report emphasises the significance of considering spontaneous non-insertional iliopsoas tendon tears when evaluating cases of acute groin pain. This finding underscores the effectiveness of ultrasound as an initial diagnostic tool for the early cost-effective diagnosis of soft tissue injuries around the hip joint, especially in low-resource settings. Timely detection and management can help avoid unnecessary operative interventions and facilitate faster and better recovery.

Purpose: The aim was to compare the use of different tools within the ImageJ program (polygon vs. segmented line) and their impact on the calculation of muscle area and echo intensity (EI) values in ultrasound imaging of the vastus lateralis muscle.
Methods: Thirteen volunteers participated in this study. Ultrasound images of the vastus lateralis muscle were acquired using 2D B-mode ultrasonography and analyzed using both the polygon and segmented line tools by the same evaluator. The intraclass correlation coefficient (ICC) and coefficient of variation (CV) assessed the tools' reliability. Bland-Altman plots were employed to verify the agreement between measurements, and linear regression analysis determined proportional bias. A paired t-test was conducted to analyze differences between the tools.
Results: The reliability between tools for muscle area calculation was weak (r = 0.000; CV = 138.03 ± 0.34%), while it was excellent for EI (r = 0.871; CV = 15.19 ± 2.96%). The Bland-Altman plots indicated a large bias for muscle area (d = 195.2%) with a proportional bias (p < 0.001). For EI, the bias was (d = 15.2) with proportional bias (p = 0.028). The paired t-test revealed significant differences between the tools for area (p < 0.001) but not for EI (p = 0.060).
Conclusion: The study found significant differences in measurements obtained with the polygon and segmented line tools in ImageJ, with the polygon tool showing higher values for muscle area and lower values for EI.

Hepatic portal venous gas (HPVG) indicates an abnormal gas buildup within the portal venous system, associated with severe medical conditions. Causes include heightened intraluminal pressure, bowel wall disruption, bowel necrosis, and pathogenic bacteria. Previously considered indicative of extensive bowel necrosis requiring surgery, HPVG is now recognized in non-surgical conditions, posing diagnostic challenges. Doppler-coupled sonography, particularly sensitive for HPVG detection, serves as a valuable initial screening tool. This article synthesizes findings from ultrasound methods for assessing portal venous gas reported in the literature and introduces a new approach using Color M-mode ultrasound.
肝门静脉积气(HPVG)是指门静脉系统内的异常气体积聚,与严重的医疗状况有关。原因包括腔内压力升高、肠壁破坏、肠坏死和致病细菌。HPVG 以前被认为是需要手术治疗的大面积肠坏死的征兆,但现在人们认识到 HPVG 可用于非手术治疗,这给诊断带来了挑战。多普勒耦合超声检查对 HPVG 检测特别敏感,是一种宝贵的初步筛查工具。本文综述了文献中报道的评估门静脉气体的超声方法,并介绍了一种使用彩色 M 型超声的新方法。

The introduction of the xxxxxxxx (GIBPS) technique represents a patient-centric novel and innovative method of ultrasound guided corticosteroid injection targeting the Glenohumeral joint (GHJ) and the Subacromial-Subdeltoid (SASD) bursa in a sequential manner, in the same setting. By integrating the two different sites of injection into a single technique, the procedure has the potential of transforming musculoskeletal interventional radiology and maximising patient care in shoulder pathologies. This procedure aims to reduce patient discomfort, optimise procedural efficiency, and enhance treatment precision through ultrasound guidance and improve the overall patient experience.

Background: Obstetric anal injury is the main risk factor for traumatic anal, faecal and flatus, incontinence in women in reproductive age. Its recognition and good reparation are crucial for long term outcomes.
Case report: We report a case of a nulliparous woman who reported a fourth-degree perineal tear after delivery. The obstetric anal sphincter injury was repaired and a four-dimensional transperineal ultrasound was performed after reparation and then one and three months after discharge. The woman did not experience any incontinence and no points of discontinuity were observed at tomographic ultrasound imaging reconstruction. In this case, 4D-TPUS was a tool in the obstetrician's hands to evaluate the surgical success of OASIS repair, which requires some expertise.
Conclusions: 4D-TPUS ultrasound is useful and reliable during immediate puerperium and in the subsequent follow-up, giving positive feedback on the correct positioning of the stiches and on a good healing process. Further studies are needed to demonstrate this usefulness in the operators training and for improving their surgical skills.
