📃Scientific paper: Ultrasound imaging of male urethral stricture disease: a narrative review of the available evidence, focusing on selected prospective studies Abstract: Purpose To synthetize the current scientific knowledge on the use of ultrasound of the male urethra for evaluation of urethral stricture disease. This review aims to provide a detailed description of the technical aspects of ultrasonography, and provides some indications on clinical applications of it, based on the evidence available from the selected prospective studies. Advantages and limitations of the technique are also provided. Methods A comprehensive literature search was performed using the Medline and Cochrane databases on October 2022. The articles were searched using the keywords “sonourethrography”, “urethral ultrasound”, “urethral stricture” and “SUG”. Only human studies and articles in English were included. Articles were screened by two reviewers (M.F. and K.M.). Results Our literature search reporting on the role of sonourethrography in evaluating urethral strictures resulted in selection of 17 studies, all prospective, even if of limited quality due to the small patients’ number (varied from 28 to 113). Nine studies included patients with urethral stricture located in anterior urethra and eight studies included patients regardless of the stricture location. Final analysis was based on selected prospective studies, whose power was limited by the small patients’ groups. Conclusion Sonourethrography is a cost-effective and safe technique allowing for a dynamic and three-dimensional urethra assessment. Yet, because of its limited value in detecting p...

📃Scientific paper: Pre-operative ultrasound mapping before arteriovenous fistula formation: an updated systematic review and meta-analysis Abstract: Background Arteriovenous fistula represents the preferred vascular access for patients with kidney failure requiring hemodialysis. Surgeons have traditionally used physical examination to identify the most suitable vessels. This meta-analysis aims to evaluate whether ultrasound mapping should be routinely performed before arteriovenous fistula creation. Methods Medline, Scopus, Web of Science and CENTRAL were systematically searched from inception to November 1, 2022. Randomized controlled trials and cohort studies comparing routine ultrasound mapping to physical examination in terms of arteriovenous fistula patency were included. Meta-analysis was performed by fitting random-effects models. The study protocol has been prospectively registered in PROSPERO (CRD42023402390). Results Overall, 18 studies were included, comprising 3655 participants. Routine pre-operative ultrasound mapping was associated with significantly lower rates of primary arteriovenous fistula failure (Risk Ratio-RR: 0.56, 95% confidence intervals-CI: 0.37–0.84, low certainty). A significant outcome was observed by separately pooling randomized controlled trials (RR: 0.37, 95% CI: 0.25–0.54). Routine ultrasound mapping was also associated with significantly higher rates of 1-year primary arteriovenous fistula patency (RR: 1.33, 95% CI: 1.19–1.47, moderate certainty). This effect remained significant in the analysis of randomized controlled trials (RR: 1.26, 95% CI: 1.02–1.56). Conclusions Impl...

👉 Oncological lung CT: Common, important and always time-consuming!

When it comes to ultrasound capabilities and spine surgery, I believe we are only utilizing the tip of the iceberg. One of the most promising capability that is close to emerging to the surface of clinical use is Contrast Enhanced Ultrasound (CEUS). Please use our recently published article as a primer for CEUS and its potential for spinal cord injury! And stay tuned in as we are soon to wrap up and share the results of our clinical trial using CEUS in patient's with cervicothoracic spondylotic myelopathy. Stephen P.

Focused Ultrasound Therapy for Essential Tremor via Focused Ultrasound Foundation: https://lnkd.in/eVTNc7hS. "Focused ultrasound is a noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with essential tremor. This novel technology focuses multiple beams of ultrasound energy precisely and accurately on targets deep in the brain without damaging surrounding normal tissue. How it Works: Where the focused ultrasound beams converge, they produce precise ablation (thermal destruction of tissue), enabling ET to be treated noninvasively. The primary target is a region in the thalamus called the ventral intermediate nucleus (Vim), but other adjacent targets and white matter pathways are also in use. Advantages: - It is a noninvasive, single treatment that enables patients to recover rapidly and quickly return to activities of normal life (usually the next day). - Compared to RF ablation or DBS, focused ultrasound offers a reduced risk of infection, of damage to the non-targeted area, and of blood clot formation. - Focused ultrasound offers rapid resolution of symptoms. - In contrast to lesioning performed with stereotactic radiosurgery, focused ultrasound does not use ionizing radiation, thus avoiding the side effects of exposure to radiation. - Because it is non-invasive, focused ultrasound could be an option for medically refractory ET patients (those who do not respond well to medication) who do not want to undergo surgery. #EssentialTremorTreatment #ParkinsonsTreatment #FocusedUltrasound #AMMG #AgeManagementMedicine #CMEEducation #ContinuingMedicalEducation #CMEConferences

✨Exciting Research Update! Mahta Mazloumi, PhD,Application Specialist at QAELUM, shares groundbreaking insights from a study in European Radiology. The study investigates how contrast agents (CA) impact organ radiation doses in contrast-enhanced CT scans. Through extensive analysis of phantom and patient data, researchers discovered a significant increase in radiation dose with the presence of CA, highlighting a direct linear relationship between absorbed dose and iodine concentrations. Key findings include a staggering 30% rise in organ doses compared to non-contrast scans, with dose distributions varying in patients. The radiobiological risk of iodine-induced increase in the radiation dose, however, requires further investigations.  https://lnkd.in/e_R_Rz9b #Radiology #CTScans #MedicalResearch

Intravascular ultrasound (IVUS) is a powerful tool to guide revascularization procedures, such as angioplasty and stenting, to improve patient outcomes. This expert roundtable brought six societies together in a discussion that will help shape future research, training and clinical guidelines in the field of lower extremity revascularization.

Shape-shifting ultrasound stickers detect post-surgical complications . Gastrointestinal surgeries carry risk of fluid leaks, a potentially life-threatening complication. But no existing methods can reliably and non-invasively detect these leaks. To address this unmet need, researchers developed a tiny, soft, flexible sticker that changes in shape inside the body, enabling standard ultrasound tech to detect leaks for earlier detection and intervention. After the patient has recovered, the soft, tiny sticker simply dissolves away. #ScienceDailynews #InnovativeResearch #NextGenScience #ExploringFrontiers

MRI is More Effective than Ultrasound for Diagnosing Adnexal Lesions!

📃Scientific paper: Interobserver variability of ultrasound measurements for the differential diagnosis of uterine prolapse and cervical elongation without uterine prolapse Abstract: Objectives Our study aims to determine the interobserver variability of different ultrasound measurements (pubis-cervix distance, pubis-uterine fundus distance, and pubis-Douglascul-de-sac distance) previously analyzed for the ultrasound differential diagnosis of uterine prolapse (UP) and cervical elongation CE without UP. Materials and methods We conducted a prospective observational study with 40 patients scheduled to undergo surgical correction of UP and CE without UP. All patients underwent pelvic floor ultrasound examination by an examiner (E1) who acquired ultrasound images. Using these images, E1 measured the distances for the ultrasound differential diagnosis of UP and CE without UP, and these distances were compared with those measured by the other examiner (E2). Values were analyzed by calculating ICCs with 95% CIs. Results For UP, excellent reliability was obtained for all measurements except the pubis-Douglascul-de-sac measurement at rest, which was moderate (ICC 0.596; p = 0.028) and for the difference between the pubis-Douglascul-de-sac measurement at rest and during the Valsalva maneuver, which was good (ICC 0.691; p < 0.0005). For CE without UP, interobserver reliability was excellent for all measurements analyzed except the pubis-cervix measurement during the Valsalva maneuver, which was moderate (ICC 0.535; p = 0.052) and for the pubis-Douglascul-de-sac measurement at rest, which was good (ICC 0.768; p < 0.0005).
