Ultrasound

Researchers are testing whether a portable ultrasound device can confirm that a nasogastric tube sits correctly in the stomach. The study enrolls 675 adults who need a tube for feeding, drainage, or medication. Doctors scan the neck and upper abdomen with ultrasound and compare t…

This study explores whether artificial intelligence can analyze ultrasound images of muscles to detect intensive care unit-acquired weakness (ICUAW), a common complication in critically ill patients. Researchers will compare AI-based assessments with standard clinical evaluations…

This study tested whether ultrasound can accurately diagnose mild to moderate carpal tunnel syndrome (CTS) by measuring the median nerve. Researchers compared ultrasound results with standard nerve tests and checked how they related to pain, symptoms, and quality of life in 75 pe…

This study tested whether a noninvasive ultrasound done on the outside of the perineum (transperineal) can accurately measure cervical length in pregnant women, compared to the standard internal (endovaginal) method. Researchers enrolled 85 women in their second or third trimeste…

Researchers are studying whether supervised toe spreading exercises can improve juvenile hallux valgus, a bunion that develops in young people. Participants do the exercises for three months while researchers track changes in the big toe angle, the abductor hallucis muscle, and f…

This trial tests whether wearing a virtual reality headset showing an underwater nature scene with relaxing music can reduce pain, anxiety, and fear in people undergoing a thyroid fine-needle aspiration biopsy. The biopsy is a standard but sometimes uncomfortable procedure used t…

This study tests a new rehabilitation approach for children aged 6-14 with dysfunctional voiding, a condition where the bladder doesn't empty properly. The researchers compare standard pelvic floor muscle training with ultrasound guidance to a newer method that adds dynamic neuro…

This trial compares two ways to manage pain after an open total abdominal hysterectomy: an ultrasound-guided rectus sheath block (a numbing injection into the abdominal wall) versus intrathecal morphine (a spinal injection). About 80 women aged 18-65 will be randomly assigned to …

This trial tests three methods of delivering the anesthetic bupivacaine to reduce pain after total abdominal hysterectomy: an ultrasound-guided rectus sheath block, a surgical rectus sheath block, or local infiltration. The study includes 90 adults aged 18–65 scheduled for electi…

This study tested whether low-intensity focused ultrasound (LIFU) can safely reduce cravings in people with cocaine use disorder. 25 adults received either real or fake (sham) ultrasound while their brain activity was measured with MRI. The goal was to see if LIFU lowers craving …

This study tested two different pain-relief methods for children aged 1 to 7 having hernia surgery. One method uses an ultrasound to guide a numbing injection near the belly muscles, while the other is a standard injection near the tailbone. The goal was to see which one keeps ch…

This study tested two methods—ultrasound and Brainlab navigation—to deliver a nerve block (numbing injection) during sinus surgery. The goal was to see which technique provides a clearer surgical field by reducing bleeding. Sixty adults undergoing sinus surgery were randomly assi…

This study looks at whether ultrasound scans of the heart, lungs, and diaphragm can predict if a surgical ICU patient will successfully come off a ventilator. Researchers will collect ultrasound images and clinical data from 190 adults who have been on a ventilator for at least 4…

Researchers are observing adults who need a radial artery catheter for elective heart surgery to see whether the procedure changes the artery's size, blood flow, or fine motor skills over three months. The study uses ultrasound to measure the radial and ulnar arteries and the Pur…

This study looks at how lung ultrasound can help find lung issues early in women who are critically ill due to pregnancy complications or gynecologic cancer. Researchers will check for different lung ultrasound patterns and see if they relate to patient outcomes like death or nee…

This study tested whether having patients stand during an ultrasound helps doctors see small liver tumors near the diaphragm that are often missed when lying down. Researchers scanned 95 people with confirmed liver lesions in three positions: standing, lying on their back, and ly…

This completed observational study looked at 84 people to understand how diabetic polyneuropathy (nerve damage from diabetes) changes the median nerve in patients with carpal tunnel syndrome. Researchers used advanced ultrasound techniques, including shear wave elastography and m…

This completed study used ultrasound to examine the structure of nerves in the neck (the brachial plexus) in 200 adults scheduled for elective surgery. Researchers recorded how many nerve bundles were visible at different nerve roots. The goal was to better understand normal anat…

This study tested whether dexmedetomidine, a sedative often used during surgery, changes how quickly the stomach empties in people having their gallbladder removed. Researchers used ultrasound to measure stomach volume in 80 patients before and after surgery. The goal was to see …
