Adnexal torsion is the rotation of the ovary around its vascular axis resulting, in the absence of treatment, ischemia that can lead to peritonitis by necrosis or impaired fertility. It is a gynecological emergency affecting 3% of women of childbearing age, including from adolescence, and requires surgical treatment as soon as possible, classically within 6 hours.
The symptomatology of adnexal torsion is dominated by pelvic pain of sudden onset and variable intensity, an aspecific sign that does not allow a diagnosis of certainty. There are no biological markers and, in the context of the emergency, the only imaging examination available is pelvic ultrasound associated with a Doppler flow analysis but with a low and variable diagnostic performance depending on the studies (sensitivity variable from 46 to 73%).
There are currently no tests that can provide a diagnosis of certainty. Only surgical exploration, carried out at the discretion of the practitioner on the basis of a bundle of arguments, can confirm or refute the diagnosis. However, this management strategy leads to the realization of emergency surgical interventions wrongly since 3 out of 10 women will finally not have an adnexal torsion (PMSI data from participating centers: 30 to 45% false positives).
Contrast ultrasound is a technique that uses a strict intravascular product to assess the vascularization of the ovary and offers a high diagnostic performance in the context of adnexal torsion. Indeed, a retrospective study, published in 2021, reports a sensitivity of 94% and a specificity of 100%. The preliminary results of our pilot study (AGATA APJC 2019, Dr Bertholdt, NCT04522219) also go in this direction with a sensitivity of 100%, a specificity of 86% and a negative predictive value of 100% (data being published).
The COVARIAN project, second stage of the AGATA project, aims to demonstrate that the addition of a contrast evaluation to standard ultrasound in the diagnostic strategy in case of suspicion of adnexal torsion improves the health of women by reducing the rate of wrongly surgery, that is, without proven torsion.
COVARIAN will be the first prospective multicenter randomized study evaluating the direct benefit for women of using ultrasound contrast evaluation in the management strategy in case of suspicion of adnexal torsion.

Contribution of Contrast-Enhanced Ultrasound (CES) in the Fetal-placental Circulation Study

Preeclampsia and intrauterine growth restriction (IUGR) are two principal complications of pregnancy. These diseases are related to placental dysfunction nevertheless knowledge of its pathophysiological mechanisms remains inadequate.
No etiological treatment for these pathologies is available. Inducing birth is the only way to prevent the occurrence of these complications (such as fetal death in utero.
Therefore, a better understanding of placental vascularization under pathological and physiological conditions is necessary. This placental vascularization evolves throughout gestation. Histological studies have improved our knowledge of placental vascular pathologies; however, these are ex vivo data that only provide an incomplete reflection of placental function. In vivo placental studies are therefore essential to understand the mechanisms of placental perfusion. Currently, these studies are limited because the available tools (such as placental Doppler) do not allow for the separate study of maternal placental flow from fetal flow. However, histological evidence clearly establishes maternal placental vascular involvement in IUGR. It would therefore be interesting to study maternal and fetal placental vascularization separately. The development of new in vivo imaging exploration techniques will help to better understand placental pathologies.
In obstetrics, CES would offer the opportunity to study in vivo placental vascularization in a segmented manner (maternal versus fetal side independently) since the microbubbles do not cross the placental barrier. Animal studies show no toxic effects on fetal development nor any crossing of the placental barrier. In humans, the innovative use of this contrast agent has allowed for a better understanding of placental vascularization in the first trimester of pregnancy.

2D and 3D Contrast Enhanced Ultrasound of Chemoembolization

This phase II trial evaluates the diagnostic performance of contrast-enhanced ultrasound (CEUS) for assessing treatment response in patients undergoing transarterial chemoembolization (TACE) for liver tumors. TACE is a hepatic artery embolization technique involving the injection of a blocking agent and a chemotherapy agent to treat liver cancers. Currently, contrast enhanced magnetic resonance imaging or computed tomography are used to assess disease response 1-2 months after TACE treatment, but ultrasound may be a less expensive, earlier alternative. CEUS is an imaging procedure that uses high-frequency sound waves to generate images of the body after administering lumason, an imaging agent used to enhance visualization of blood flow on ultrasounds. CEUS is able to be performed during the TACE procedure, making it possible to evaluate treatment response earlier than standard techniques. CEUS may be an effective method to evaluate treatment response more accurately and much earlier than current standard evaluation methods.

A Comparative Study of SonoVue and Sonazoid for Contrast-Enhanced Ultrasound CT/MRI Fusion Guidance During Radiofrequency Ablation of Poorly Visualized Hepatic Malignancies: A Prospective Intra-Individual Analysis

Article

作者: Kim, Jae Hyun ; Kim, HeeSoo ; Lee, Jeong Min

PURPOSE:

This study aimed to evaluate the effectiveness of two contrast agents, SonoVue (SV) and Sonazoid (SZ), by comparing them intra-individually in contrast-enhanced ultrasound (CEUS)-CT/MRI fusion imaging (FI) to improve the visibility of inconspicuous liver malignancies on B-mode sonography for guiding percutaneous radiofrequency ablation (RFA). Additionally, the radiologists' preference between SonoVue- CT/MRI FI (SV-FI) and Sonazoid-CT/MRI FI (SZ-FI) was determined.

METHODS:

This prospective study enrolled 23 patients with inconspicuous hepatic malignancies (≤ 3 cm) on B-mode US who underwent both SV-FI and SZ-FI for RFA guidance. The patients underwent real-time CEUS FI with CT/MRI on the same day, utilizing both SV and SZ with at least 15-min intervals. Tumor visibility and radiologists' preferences were assessed and graded using a 4-point scale during the dynamic phases of both SV-FI and SZ-FI and the Kupffer phase of SZ-FI.

RESULTS:

The tumor visibility scores obtained from CEUS-CT/MRI FI were significantly better than those obtained from US-FI. Indeed, SV-FI and SZ-FI demonstrated comparable visibility scores when corresponding phases were compared (p > 0.05). However, the Kupffer phase images of SZ-FI displayed superior visibility scores (3.70 ± 0.56 vs. 2.96 ± 0.88; p = 0.002) than the late vascular phase images of SV-FI. The radiologists favored SZ-FI in many cases, exhibiting moderate inter-observer agreement (Kappa value = 0.587; 95% CI, 0.403-0.772).

CONCLUSION:

Although CEUS-CT/MRI FI with either SV or SZ substantially improved the visibility of inconspicuous tumors on US-CT/MRI FI, radiologists preferred SZ to SV to guide the RFA procedure.

Investigation Into the Subharmonic Response of Three Contrast Agents in Static and Dynamic Flow Environments Using a Commercially Available Diagnostic Ultrasound Scanner

Article

作者: Forsberg, Flemming ; Wallace, Kirk ; Eisenbrey, John R. ; Eisenbrey, John R ; Vu, Trang ; Mayer, Hailee ; Machado, Priscilla ; Kim, Ga Won

OBJECTIVE:

The objective of this study was to investigate the subharmonic response of Lumason (also known as SonoVue; Bracco, Milan, Italy) to static and dynamic ambient pressures, with a direct comparison to Sonazoid (GE HealthCare, Oslo, Norway) and Definity (Lantheus Medical Imaging, MA, USA). The subharmonic responses of contrast agents can be exploited to perform subharmonic-aided pressure estimation.

METHODS:

The subharmonic response of each ultrasound contrast agent was evaluated in both a static and dynamic tank using a commercially available Logiq E10 clinical ultrasound scanner (GE HealthCare) equipped with subharmonic imaging (SHI) and an acoustic power-optimization algorithm. A C1-6 curvilinear array that transmits at 2.5 MHz and receives at 1.25 MHz in SHI mode was used to acquire the subharmonic signals. Data was transferred offline into MATLAB (MathWorks) to perform linear regression analysis and statistical testing for significance of the slopes (i.e., agent sensitivity).

RESULTS:

Sonazoid and Definity showed an inverse linear dependency between subharmonic signal and hydrostatic pressure at all pressure ranges (static and dynamic) tested, with maximum sensitivity under 50 mmHg in the static tank (-0.190 and -0.194 dB/mmHg for Sonazoid and Definity, respectively). Lumason exhibited a tri-phasic subharmonic behavior, beginning with a linear trend from 0 to 90 mmHg (sensitivity = 0.069 dB/mmHg), followed by a plateau from 100 to 130 mmHg, and an inverse linear trend from 140 to 200 mmHg (sensitivity = -0.137 dB/mmHg).

CONCLUSION:

The subharmonic response of Lumason is tri-phasic and differs from Sonazoid and Definity. Further investigation is needed to solidify understanding of the subharmonic behavior of Lumason to identify its usefulness for subharmonic-aided pressure estimation.

The impact of short-term postoperative face-up position on unintentional retinal displacement after pars plana vitrectomy for rhegmatogenous retinal detachment

Article

作者: Iros, Mariano ; Francone, Anibal ; Lopez, Juan Manuel ; Miere, Alexandra ; Souied, Eric H. ; Bernard, Agnes Glacet ; Crincoli, Emanuele ; Mehanna, Carl-Joe

Objective:

To assess the effectiveness and safety of a rigorous short-term supine position in preventing inadvertent retinal displacement after pars plana vitrectomy (PPV) with gas tamponade for rhegmatogenous retinal detachment (RRD).

Methods:

We conducted a retrospective observational analysis of a case series at two ophthalmological surgical centers. We included eyes diagnosed with macula-off RRD that maintained a strict face-up position for three hours immediately after PPV with intraoperative perfluorocarbon liquid (PFCL) and 20% sulfur hexafluoride (SF6) tamponade. Fundus autofluorescence (FAF) imaging was performed at one month post-operatively to identify unintentional retinal displacement through the detection of retinal vessel prints (RVPs) on FAF imaging using an ultrawide-field (UWF) imaging system.

Results:

A total of 29 eyes with macula-off RRD were included in the study. The average age of the participants was 59.62 years. RRD involved one quadrant in two eyes, two quadrants in fourteen eyes, three quadrants in seven eyes, and four quadrants in six eyes. UWF-FAF imaging at one month follow-up after complete reattachment of the retina revealed RVPs in seven out of the 29 eyes (24.13%), with a mean displacement of 0.22 mm. In every case the displacement occurred downward.

Conclusion:

Our results suggest that adhering to a strict face-up position for three hours after PPV with PFCL and gas tamponade for macula-off RRD may lead to a low frequency and severity of inadvertent post-operative retinal displacement.
