B-mode ultrasonography is a non-invasive and accessible method for assessing muscle thickness; however, ultrasound-based measurements may be influenced by image acquisition, anatomical landmark identification, and operator-dependent measurement procedures. Establishing inter-rater reliability is therefore essential to determine whether different assessors can obtain consistent measurements of muscle thickness from the same ultrasound images. The rectus abdominis is an important component of the abdominal musculature and contributes to trunk stabilization and functional performance during exercise. Blood flow restriction (BFR) training has gained increasing attention as a low-load exercise strategy for promoting muscular adaptations, although research has predominantly focused on peripheral limb muscles. Therefore, this study aims to evaluate the inter-rater reliability of ultrasound-based rectus abdominis muscle thickness measurements following a standardized BFR training protocol using ImageJ software. Establishing reliable measurement of rectus abdominis thickness will provide a methodological basis for future research investigating abdominal muscle morphology and adaptations in sports physiotherapy, exercise rehabilitation, and BFR-based training.",[26,27],"Reliability","Ultrasound","RECRUITING","2026-08-05",{"date":31,"type":32},"2026-08-10","ACTUAL",{"date":34,"type":32},"2026-08-04",{"date":36,"type":22},"2026-09-20",{"name":38,"class":39},"Riphah International University","OTHER",1,{"id":42,"slug":43,"hasResults":12,"nctId":44,"briefTitle":45,"officialTitle":45,"acronym":4,"eligibilityCriteria":46,"healthyVolunteers":12,"sex":47,"minAge":4,"maxAge":4,"enrollmentInfo":48,"targetDuration":4,"studyType":50,"phases":51,"briefSummary":53,"conditions":54,"keywords":4,"overallStatus":57,"whyStopped":4,"lastUpdateSubmitDate":34,"lastUpdatePostDateStruct":58,"startDateStruct":59,"completionDateStruct":61,"leadSponsor":63,"locationsCount":40},"100650966","safety-and-efficacy-of-microwave-ablation-alone-versus-microwave-ablation-combined-with-chemical-ablation-in-the-treatment-of-uterine-fibroids-a-prospective-multicenter-study-100650966","NCT07754877","Safety and Efficacy of Microwave Ablation Alone Versus Microwave Ablation Combined With Chemical Ablation in the Treatment of Uterine Fibroids: A Prospective, Multicenter Study","Inclusion Criteria:\n\n1.

Current treatments include pharmacological therapy (GnRH-a, mifepristone) - effective temporarily but with high recurrence after discontinuation; surgical myomectomy or hysterectomy - definitive yet invasive, with prolonged recovery and potential fertility compromise; and minimally invasive therapies such as uterine artery embolization (UAE), high-intensity focused ultrasound (HIFU), and microwave ablation (MWA), which are increasingly favored for their minimal invasiveness and rapid recovery.\n\nMWA delivers thermal energy via a percutaneously inserted antenna under ultrasound guidance, inducing coagulative necrosis of fibroid tissue through temperatures exceeding 60°C. Advantages include minimal trauma (\\~2 mm puncture), rapid recovery (discharge within 1-2 days), uterine preservation, and negligible ovarian impact. However, a key limitation is the heat sink effect: in hypervascular fibroids, flowing blood dissipates thermal energy, resulting in incomplete ablation, prolonged procedural time, and higher energy requirements - particularly challenging for fibroids \\>5 cm in diameter.\n\nChemical ablation involves intralesional injection of a sclerosing agent (e.g., lauromacrogol), which damages vascular endothelial cells, causing vascular occlusion, thrombosis, ischemic necrosis, and direct membrane disruption that accelerates apoptosis. Theoretically, pre-ablation chemical sclerotherapy may occlude feeding vessels, attenuate the heat sink effect, and enhance subsequent thermal ablation efficiency. Supporting this concept, an ex vivo bovine liver study demonstrated that pre-injection of 5 mL of 99.5% ethanol around the electrode prior to radiofrequency ablation produced a significantly larger ablation zone at equivalent energy levels compared with ablation alone. Small-sample clinical studies, including a prospective cohort from Shanghai Tenth People's Hospital, have preliminarily explored combined chemical ablation plus MWA for uterine fibroids, suggesting improved ablation rates and shorter procedural times, though findings require validation through high-quality randomized controlled trials.\n\nTherefore, the investigators conducted this multicenter, prospective, randomized controlled trial to rigorously compare the safety (incidence and severity of adverse events) and efficacy (fibroid volume reduction rate, symptom improvement, quality-of-life outcomes) of MWA alone versus MWA combined with chemical ablation. This study aims to clarify the clinical value of the combined approach and provide high-quality, evidence-based data to guide the optimal selection of minimally invasive treatment strategies for uterine fibroids.",[55,56,27],"Uterine Fibroids (UF)","Microwave Ablation","NOT_YET_RECRUITING",{"date":31,"type":32},{"date":60,"type":22},"2026-08-01",{"date":62,"type":22},"2028-08-30",{"name":64,"class":39},"Peking University Aerospace Center Hospital",{"id":66,"slug":67,"hasResults":12,"nctId":68,"briefTitle":69,"officialTitle":70,"acronym":71,"eligibilityCriteria":72,"healthyVolunteers":73,"sex":74,"minAge":18,"maxAge":4,"enrollmentInfo":75,"targetDuration":4,"studyType":23,"phases":4,"briefSummary":77,"conditions":78,"keywords":4,"overallStatus":57,"whyStopped":4,"lastUpdateSubmitDate":83,"lastUpdatePostDateStruct":84,"startDateStruct":86,"completionDateStruct":88,"leadSponsor":90,"locationsCount":40},"100650808","transthoracic-ultrasound-for-descending-aortic-aneurysms-100650808","NCT07752654","TransThoracic Ultrasound for Descending Aortic Aneurysms","Feasibility, Accuracy and Reproducibility of Ultrasound in Aneurysms of the Descending Thoracic Aorta","THORUS","Inclusion Criteria:\n\n* Patients with diagnosed AAA or other vascular condition attending the vascular scanning department for routine ultrasound and confirmed healthy DTA (Control group).\n* Patients with known DTAA (including Type B dissection) or patients who had TEVAR previously (Case group).\n* Patients who have had CT as part of their standard of care.\n* Patients able to tolerate the scan (Lying in supine position).\n* Adults aged 18 or over.\n* Willing to provide consent.\n\nExclusion Criteria:\n\n* Patient under 18 years of age.\n* Previous thoracic surgery or body deformity (severe kyphosis, scoliosis, pleural effusion or chest wall trauma).\n* Patients without previous imaging of the thoracic aorta.\n* Life expectancy \\\u003C2 years.\n* Pregnant Women.\n* Patients unwilling to provide consent or unable to comply with study requirements.\n* Patients too frail to travel to routine outpatient appointments.\n* Inability to attend the appointment due to time constraints or other commitments.\n* Although rare, ultrasound contraindications as described in the scanning protocol are also exclusion criteria.",true,"ALL",{"count":76,"type":22},60,"The goal of this observational study is to assess the applicability of non-invasive ultrasound in aneurysms of the descending thoracic aorta.\n\nThe main question it aims to answer is:\n\nWhat is the feasibility of Ultrasound to visualise the Descending Thoracic Aorta, and can this imaging modality accurately measure the maximum size of aneurysms and residual sacs with acceptable reproducibility?\n\nParticipants are having their diagnosis confirmed or excluded by conventional imaging techniques (CT scans).

This can lead to serious cardiovascular disease such as a heart attack or stroke causing over 160,000 deaths each year.\n\nLots of research has been done on why particular groups of people may develop atherosclerosis and controlling risk factors such as diabetes and high blood pressure go a long way to reduce people's risks. However, despite the treatments we have available and controlling these risk factors, some people unfortunately still go on to develop a potentially serious disease.\n\nFurther research has shown us that certain plaques in the blood vessels may be more vulnerable to rupturing compared to others. So far we know that plaques with thin caps, soft centres or those that are able to grow their own tiny blood vessels are more likely to rupture. We have now started to develop new imaging methods to try and help us detect these vulnerabilities. The hope is by being able to detect more vulnerable plaques we may be able to treat these earlier and therefore more effectively.\n\nThere are different scans available to try and visualise the tiny vessels within these plaques in the neck arteries. These include, MRI (a Magnetic Resonance Imaging scan, taking pictures using a small tunnel), CT (Computed Tomography, uses a ring-shaped machine to take pictures), and ultrasound. Ultrasound has the benefit of being free of ionising radiation and iodinated contrast, therefore posing less risk to patients. However, current ultrasound uses 2D ultrasound. Although this has shown promising results, our blood vessels and any plaques are 3D structures so we don't get to see the whole plaque using 2D imaging and therefore may miss important information. The available 3D probes in use at the moment are not able to visualise the tiny vessels accurately enough.\n\nThis study uses a different 3D ultrasound probe and ultrasound machine that is able to produce many more images than our usual probes.
