Filter by:In the study, we aimed to characterize the role of FDG PET/CT surveillance at 12 months of malignant lymphoma in asymptomatic patients after a first complete remission and to define a rational follow-up strategy.
This study evaluates the effect of a supervised exercise program on paraspinal muscle morphology and function, as well as disability/function in patients with non-specific chronic low back pain. Half of the participants will do a targeted paraspinal muscle exercise program, while the other half will do a general exercise program.
In this study, a prospective, randomized and controlled clinical study would be carried out to establish Ultrasound Integrated Precision Diagnosis Technology with elastography as the core technology to evaluate renal injury and repair comprehensively and accurately, and to improve the clinical diagnosis chance of renal injury (or renal fibrosis). Combined with the dynamic changes of biomarkers (inflammatory factors, cytokines secreted by immune cells, etc.) after kidney injury, the research on the prognosis of kidney disease with ultrasound elastography technology as the core would be explored, which aims to provide a scientific basis for the application of Ultrasound Integrated Precision Diagnosis Technology.
The investigators hypothesize that sub-mental ultrasonography measures are strongly correlated with the severity of Obstructive Sleep Apnea Syndrome and the related specific subjective scales.
Lung Ultrasonography (US) has been shown to be effective for verifying endotracheal tube (ETT) position in adults and children but has been less studied in neonates. The aim of this study is to evaluate the performance of lung US in determining correct ETT position in neonates, in comparison with X Ray
Although the lumbar puncture is a common procedure and has been performed without ultrasound for decades, other research studies suggest that there may be some benefits to using ultrasound. This study intends to see whether by using ultrasound there is increased success rate, decreased need for additional procedures, and less discomfort during the procedure.
This clinical trial studies how well positron emission tomography (PET)/computed tomography (CT) works compared to PET/magnetic resonance imaging (MRI) in evaluating patients with cancer. PET/CT and PET/MRI may determine which scanner is best for the patient's type of cancer and other types of cancers.
Transforaminal epidural block (TFEB) with local anesthetics and steroid is effective to treat spinal radicular pain. However, inadvertent intravascular injection can lead to severe neurologic complications. Digital subtraction angiography (DSA) during epidural block might increase the detection rate of intravascular penetration, compared to real-time fluoroscopy (RTF). But, DSA has disadvantages, such as additional radiation exposure to physicians and participants and the high cost of the new and upgraded fluoroscopic equipment. In this study, it was designed to compare DSA and RTF for detection of intravascular penetration in the same participant who underwent cervical TFEB. The investigators prospectively examined the participants who received cervical TFEB. The needle position was confirmed using biplanar fluoroscopy and 2 ml of nonionic contrast media was injected at the rate of 0.5 ml/sec under RTF. Thirty seconds later, 2 ml of nonionic contrast media was injected at the rate of 0.5 ml/sec under DSA.
There are only few recognized indications for the realization of plain abdominal X-rays in the emergency departement. The objective of this study is to explore the reasons for abdominal plain X-rays prescription in the Emergency departments (EDs) of two hospitals.
Testing of a dual tuned proton/fluorine MRI radio frequency coil Images were collected from plastic fluorine phantoms taped to the upper thigh of health volunteers. This trial was performed as part of an application for a Health Canada Investigational Device Exemption (Protocol # 226949)
