NCT ID: NCT05875883 Not yet recruiting - Ultrasound Clinical Trials

Phrenic Identification in the ICU

Start date: August 7, 2023
Phase:
Study type: Observational

This will be a prospective observational study where the investigator will scan patients' necks with an ultrasound and look for anatomical landmarks that may help identify the phrenic nerve.

NCT ID: NCT05857852 Recruiting - Cocaine Dependence Clinical Trials

Low-Intensity Focused Ultrasound for Cocaine Use Disorder

Start date: March 1, 2023
Phase: N/A
Study type: Interventional

This study aims to understand the role of Low-Intensity Focused Ultrasound on craving levels for cocaine as evidenced by diagnostic imaging of the dorsal anterior insula (dAI) and subjective ratings. Data analysis will serve to show if 1) LIFU is safe and effective and to 2) examine the effects of LIFU on dAI BOLD activity and craving in response to cocaine cue-exposure. The study will screen 60 individuals with Cocaine Use Disorder (CUD) to arrive at 30 enrolled subjects, based on a 2:1 screen/randomization ratio.

NCT ID: NCT05855239 Active, not recruiting - Fatty Liver Clinical Trials

Quantification of Hepatic Steatosis With Different Ultrasound Frequency

Start date: June 8, 2023
Phase:
Study type: Observational [Patient Registry]

The objective of this study is: (1) to compare the feasibility (technical successes rate and reliability) in measuring attenuation coefficient between two different frequencies (3MHz, 4MHz) of ultrasound beam; (2) to evaluate and compare the diagnostic performance of attenuation coefficient for steatosis using two different frequencies (3MHz, 4MHz) of ultrasound beam by comparison with the pathologic results acquired by liver biopsy or surgery.

NCT ID: NCT05849909 Recruiting - Ultrasound Clinical Trials

Evaluation of the Vulnerable Carotid Atherosclerotic Plaque: A Clinical Multicenter Study

Start date: April 18, 2023
Phase:
Study type: Observational

Evaluation of carotid plaque vulnerability based on ultrasound imaging features, proteomics and metabolomics: a clinical multicenter study

NCT ID: NCT05844917 Not yet recruiting - Ultrasound Clinical Trials

Ultrasound-Based Detection Of Subclinical Arthritis Among Patients With Systemic Lupus

Start date: June 1, 2023
Phase: N/A
Study type: Interventional

The aim of this study is to assess the prevalence and precise grading of US abnormalities of the hand and wrist in asymptomatic patients with SLE, while comparing these findings with a group of patients with SLE with musculoskeletal signs or symptoms and with healthy controls.

NCT ID: NCT05819450 Recruiting - Ultrasound Clinical Trials

Sonography-Guided Volumetric Rejuvenation on Dorsal Hands

Start date: April 15, 2023
Phase: N/A
Study type: Interventional

The goal of this randomized controlled study is to guide volumetric rejuvenation on dorsal hands with the maximal aesthetic appearance. The main questions it aims to answer are: - Which fatty layer(s) is/are the most suitable for filler injection? - Is it feasible to make precise filler injections with sonography guidance? Participants will receive sonography-guided injection on the one hand and another with blinded injection.

NCT ID: NCT05798169 Recruiting - Sarcopenia Clinical Trials

Impact of Acute Hospitalisation and Resistance Training on Muscle Architecture and Physical Performance in Older Adults

Start date: January 5, 2023
Phase: N/A
Study type: Interventional

Sarcopenia characterised by loss of muscle mass, muscle strength and physical performance burdens many older adults since the condition is related to functional decline. Periods of inactivity such as during hospitalisation leads to further functional decline. It has been reported that the loss of muscle mass associated with sarcopenia not only entails a decrease in muscle mass but also changes in muscle architecture. Knowledge on changes in muscle architecture is essential since it is one of the most important determinants on muscle strength and thus physical performance. The main objective of this study is to investigate changes in muscle architecture and physical performance during acute hospitalisation and after discharge in older adults and subsequently the effectiveness of resistance training of the lower limb during acute hospitalisation. If successful, our study could have a great impact on the individual, as well as societal level, due to a better understanding of the factors related to sarcopenia and the prevention of functional decline as a result of hospitalisation.

NCT ID: NCT05785338 Completed - Ultrasound Clinical Trials

Trial Observationnal

CLEFTPALATDIAG
Start date: January 15, 2023
Phase:
Study type: Observational

The aim of this retrospective longitudinal study was to describe a key factor in the prenatal diagnosis of isolated cleft palate on the axial transverse view, in order to provide better understanding, detection and diagnosis of this anomaly.

NCT ID: NCT05761912 Not yet recruiting - Prostate Cancer Clinical Trials

Application of Ultrasound Radiomics in Ultrasound Fusion Targeted Prostate Biopsy

Start date: March 15, 2023
Phase:
Study type: Observational

To predict prostate cancer and its prognosis by ultrasound radiomics in ultrasound fusion prostate targeted biopsy.

NCT ID: NCT05742776 Recruiting - Clinical trials for Carpal Tunnel Syndrome

The Relationship Between Ultrasonographic Findings and Sleep Quality in Carpal Tunnel Syndrome

Start date: February 23, 2023
Phase:
Study type: Observational

The aim of our study is to determine the relationship between disease severity and sleep quality in CTS patients and to compare the findings with healthy controls.
